Which notation expresses the number of permutations of 8
items taken 2
at a​ time?
There are 56 possible permutations of 8 items taken 2 at a time. To express the number of permutations of 8 items taken 2 at a time, we use the notation P(8,2) or sometimes written as 8P2.
Permutations are arrangements of items in a specific order where the order matters.
To calculate the number of permutations, we use the formula:
P(n, r) = n! / (n - r)!
In our case, n is the total number of items (8) and r is the number of items taken at a time (2). Using the formula:
P(8, 2) = 8! / (8 - 2)!
= 8! / 6!
Now, let's calculate the factorials:
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
6! = 6 × 5 × 4 × 3 × 2 × 1
Divide 8! by 6!:
P(8, 2) = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (6 × 5 × 4 × 3 × 2 × 1)
Notice that the 6!, which is (6 × 5 × 4 × 3 × 2 × 1), cancels out from both the numerator and the denominator, leaving us with:
P(8, 2) = 8 × 7
P(8, 2) = 56
So, there are 56 possible permutations of 8 items.

A food company is designing boxes for several products. Each box is a rectangular prism. The company makes a single serving cereal box that contains 1. 2 ounces of cereal. They plan to make an extra large box for school cafeterias. The extra large box will be a dilation of the single serving box using a scale factor of 4. How many ounces of cereal will the extra large box contain? Explain or show your reasoning. The company also wants to offer a family size box of cereal. The family size box will be a dilation of the single serving 1. 2-ounce box. It must contain 18. 75 ounces of cereal. What scale factor does the company need to use for the family size box? Explain or show your reasoning. The food company is now designing soup boxes. The largest box of soup will be a dilation of the smallest box using a scale factor of 2. The smallest box must hold 8 fluid ounces or about 15 cubic inches of soup. Find a set of dimensions for the largest box. Round your answers to the nearest tenth if necessary. Explain or show your reasoning
Answer: For the extra large box, the scale factor is 4. The volume of the single serving box is:
V1 = l x w x h = 1.2 cubic inches
The volume of the extra large box, which is a dilation of the single serving box with a scale factor of 4, is:
V2 = (4l) x (4w) x (4h) = 64(l x w x h) = 64V1
So the extra large box will contain:
1.2 x 64 = 76.8 ounces of cereal.
For the family size box, the volume is 18.75 ounces, which is 15.6 times larger than the single serving box. The scale factor is the cube root of this ratio:
scale factor = (18.75/1.2)^(1/3) = 2.5
So the family size box will be a dilation of the single serving box with a scale factor of 2.5.
For the soup boxes, the largest box is a dilation of the smallest box with a scale factor of 2. The volume of the smallest box is 15 cubic inches, so the volume of the largest box is:
V2 = (2l) x (2w) x (2h) = 8(l x w x h) = 8 x 15 = 120 cubic inches.
We can choose any dimensions that satisfy this volume requirement. For example, we could use:
Length = 10 inchesWidth = 3 inchesHeight = 4 inches
The volume of this box would be:
V = 10 x 3 x 4 = 120 cubic inches
Therefore, a set of dimensions for the largest soup box is 10 inches by 3 inches by 4 inches, or any other dimensions that satisfy the volume requirement of 120 cubic inches.
A certain cold remedy has an 88% rate of success of reducing symptoms within 24 hours. Find the probability that in a random sample of 45 people who took the remedy, 40 of them had a reduction of symptoms within a day.
Round your answer to three decimal places.
The probability that in a random sample of 45 people who took the remedy, 40 of them had a reduction of symptoms within a day is approximately 0.674, rounded to three decimal places.
This problem can be solved using the binomial distribution.
Let X be the number of people out of 45 who have a reduction of symptoms within a day. Then X follows a binomial distribution with n = 45 and p = 0.88.
The probability of exactly 40 people having a reduction of symptoms is given by:
P(X = 40) = (45 choose 40) * (0.88)^40 * (1-0.88)^(45-40)
We can use a calculator or software to evaluate this expression. Alternatively, we can use the normal approximation to the binomial distribution, since n is large and p is not too close to 0 or 1.
Using the normal approximation, we can approximate X as a normal distribution with mean mu = n*p = 39.6 and standard deviation sigma = sqrt(n*p*(1-p)) = 1.964.
Then the probability of X being less than or equal to 40 can be approximated by the cumulative distribution function of the standard normal distribution:
P(X <= 40) = P((X - mu)/sigma <= (40.5 - 39.6)/1.964) = P(Z <= 0.458)
Using a standard normal table or software, we can find that P(Z <= 0.458) is approximately 0.6736.
Therefore, the probability that in a random sample of 45 people who took the remedy, 40 of them had a reduction of symptoms within a day is approximately 0.674, rounded to three decimal places.

The transformation from the function f(x) = 3x to the function f(x) = 3x + 4 indicates:
an upward shift of 4 units.
a downward shift of 4 units.
a shift to the left 4 units.
a shift to the right 4 units.
O
Answer: An upward shift of 4 units.
Step-by-step explanation:
The transformation of the function F(x) = 3x to F(x) = 3x + 4 indicates a vertical translation or shift of the graph of f(x) upward by 4 units.
More specifically, the original function f(x) = 3x has a y-intercept at (0,0) and a slope of 3, meaning that for every 1 unit of increase in x, there is a corresponding increase of 3 units in y. Adding 4 to the function shifts all the y-values up by 4 units, so the new function f(x) = 3x + 4 has a y-intercept at (0,4) and a slope of 3, which means that for every 1 unit of increase in x, there is a corresponding increase of 3 units in y, starting from the new y-intercept at (0,4).
If you meet all the criteria for an independent t-test, but do not satisfy the assumption of normality, you should technically _________________________.
a. redo the experiment
b. visit your therapist
c. ignore it
d. do a non-parametric test
If you meet all the criteria for an independent t-test but do not satisfy the assumption of normality, you should technically do a non-parametric test instead of an independent t-test.
So, the correct answer is D.
What's Non-parametric testsNon-parametric tests do not require the data to be normally distributed, unlike parametric tests such as t-tests. Non-parametric tests include the Mann-Whitney U test, Wilcoxon rank-sum test, and Kruskal-Wallis test.
These tests are based on ranks rather than the actual values of the data and are generally less powerful than parametric tests, meaning that they may require larger sample sizes to achieve the same level of statistical significance.
It is important to choose the appropriate statistical test for your data to ensure accurate results and conclusions. Simply redoing the experiment or ignoring the violation of the normality assumption is not a valid solution.

hypothesis that researcher tries to DISPROVE or REJECT. explain
A hypothesis is a tentative explanation for a phenomenon that is based on limited evidence and requires further investigation to be confirmed or rejected. When a researcher conducts a study, they formulate a hypothesis that they seek to test through their research.
In scientific research, a researcher aims to disprove or reject their hypothesis rather than prove it. This is because it is impossible to prove a hypothesis with complete certainty, but it is possible to gather evidence that contradicts it. By trying to disprove or reject their hypothesis, a researcher can either find evidence to support their hypothesis or identify flaws in their reasoning that they can address in future research.
For example, a researcher might hypothesize that a new drug will improve memory in Alzheimer's patients. To test this hypothesis, the researcher would administer the drug to a group of Alzheimer's patients and compare their memory performance to a control group that received a placebo. If the results show that the drug did not improve memory performance, the researcher would reject their hypothesis and revise their understanding of the drug's effects.
In conclusion, a hypothesis is a tentative explanation that a researcher tries to disprove or reject through their research. By doing so, they can either find evidence to support their hypothesis or identify flaws in their reasoning that they can address in future research.

The function f is continuous on the closed interval (1,7). If 7 to 1 f(x) dx= 42 and 3 to 7 f(x) dx= -32, then 3 to 1 2f(x) dx=-148 is not correct. The correct answer is option a.
We can use the linearity property of definite integrals to evaluate 3 to 1 2f(x) dx as follows:
3 to 1 2f(x) dx = 2 times the definite integral of f(x) from 1 to 3
+ 2 times the definite integral of f(x) from 3 to 7
- 2 times the definite integral of f(x) from 7 to 1
(Note that we have reversed the limits of integration for the last term.)
Using the given values, we have:
3 to 1 2f(x) dx = 2 times the definite integral of f(x) from 1 to 3
+ 2 times the definite integral of f(x) from 3 to 7
- 2 times (7 to 1 f(x) dx)
= 2 times (-32) + 2 times 42 - 2 times 42

The remaining players have scored an average of 14 runs each.
The total runs scored by the 11 players are:
11 players * 23 runs/player = 253 runs
If the first player scored 113 runs, then the remaining 10 players must have scored:
253 total runs - 113 runs scored by the first player = 140 runs
To find the average runs scored by the remaining players, we divide the total runs scored by the remaining 10 players by the number of players:
Average runs scored by remaining 10 players = 140 runs / 10 players = 14 runs/player

juan is a single father of 3 filing as a Head of Household. His income reported on his W-2 was $98,066 and he had interest and dividend income reported on a 1099 of $2,454. During the year, Juan had state and local taxes withheld $5,864, paid property tax of $6,487, paid $6,846 in mortgage interest, and had $8,147 in charitable contributions. The exemption amount for this year is $4,000. Use the table below to calculate their tax. If Juan's W-2 showed Federal Tax Withheld of $11,799, will he be receiving a refund or owe more taxes? How much?
Answer:
To calculate Juan's tax liability, we need to first determine his taxable income. We can do this by subtracting his exemptions and deductions from his total income:
Total income: $98,066 + $2,454 = $100,520
Exemption amount: $4,000
Standard deduction for Head of Household: $9,350 (for 2017)
Itemized deductions: $5,864 + $6,487 + $6,846 + $8,147 = $27,344
Total deductions: $9,350 + $27,344 = $36,694
Taxable income: $100,520 - $4,000 - $36,694 = $59,826
Using the tax tables for 2017, we can calculate Juan's tax liability:
Taxable income: $59,826
Tax liability: $10,517.50
Juan's W-2 shows that $11,799 was withheld for federal taxes, which is more than his calculated tax liability of $10,517.50. Therefore, Juan will receive a refund.
Refund amount: $11,799 - $10,517.50 = $1,281.50
Therefore, Juan will receive a refund of $1,281.50.
Answer:
Using the information provided, we can calculate Juan's taxable income and then use the tax table to determine his federal income tax liability. Here are the calculations:
Juan's total income:
W-2 income: $98,066
Interest and dividends: $2,454
Total: $100,520
Juan's adjustments:
Exemption amount: $4,000
Adjusted Gross Income (AGI):
Total income - Exemption amount
$100,520 - $4,000 = $96,520
Juan's deductions:
State and local taxes: $5,864
Property tax: $6,487
Mortgage interest: $6,846
Charitable contributions: $8,147
Total deductions: $27,344
Juan's taxable income:
AGI - Deductions
$96,520 - $27,344 = $69,176
Using the tax table for Head of Household filers, Juan's federal income tax liability is approximately $12,998.
Juan's federal tax withheld from his W-2 is $11,799. Since this amount is less than his tax liability of $12,998, he will owe additional taxes of approximately $1,199.
Therefore, Juan will owe an additional $1,199 in federal income taxes when he files his tax return.

The base of a pentagon lies on ray AB as shown.
An illustration showing a pentagon lying on ray AB, which when extended forms an exterior angle and is marked as 2x plus 14 degrees. The interior angle next to this exterior angle measures 7x plus 13 degrees.
Determine which statements are true.
(2x + 14)° = 48°
x = 7°
(2x + 14)° + (7x + 13)° = 180°
(7x + 13)° = 132°
(2x + 14)° = 90°
An illustration showing a pentagon lying on ray AB, which when extended forms an exterior angle and is marked as 2x plus 14 degrees, the correct statements are (2x + 14)° + (7x + 13)° = 180°, (7x + 13)° = 132°, x = 7°.
In the given illustration, we have a pentagon with base AB lying on a line or ray AB. Let's call the first interior angle to the right of the exterior angle marked as 2x + 14 degrees as angle C.
We can see that the sum of the measures of all interior angles of a pentagon is 180 degrees. Hence, the sum of all interior angles of this pentagon is:
C + angle D + angle E + angle F + angle G = (5 - 2) x 180 degrees (since a pentagon has five sides and angles)
(2x + 14)° + (7x + 13)° = 180° (sum of interior angles of a pentagon)
(7x + 13)° = 132° (simplifying the above equation)
x = 7° (solve for x by subtracting 14 from both sides of the first equation)

The point on the plane 4x - y + 4z = 40 nearest the origin is (-3.048, -0.762, 6.467)
Given data ,
To find the point on the plane 4x - y + 4z = 40 nearest the origin, we need to minimize the distance between the origin and the point on the plane.
The normal vector to the plane 4x - y + 4z = 40 is given by (4,-1,4). To find the perpendicular distance from the origin to the plane, we need to project the vector from the origin to any point on the plane onto the normal vector. Let's choose the point (0,0,10) on the plane:
Vector from origin to (0,0,10) on the plane = <0-0, 0-0, 10-0> = <0,0,10>
Perpendicular distance from the origin to the plane = Projection of <0,0,10> onto (4,-1,4)
= (dot product of <0,0,10> and (4,-1,4)) / (magnitude of (4,-1,4))
= (0 + 0 + 40) / √(4^2 + (-1)^2 + 4^2)
= 40 / √(33)
To find the point on the plane nearest the origin, we need to scale the normal vector by this distance and subtract the result from any point on the plane. Let's use the point (0,0,10) again:
Point on the plane nearest the origin = (0,0,10) - [(40 / √(33)) / √(4^2 + (-1)^2 + 4^2)] * (4,-1,4)
= (0,0,10) - (40 / √(33)) * (4/9,-1/9,4/9)
= (0,0,10) - (160/9√(33), -40/9√(33), 160/9√(33))
= (-160/9√(33), -40/9√(33), 340/9√(33))

What are the 2 theoretical quantities of ANOVA?
The two theoretical quantities of ANOVA (Analysis of Variance) are:
1. Between-group variance.
2. Within-group variance:
1. Between-group variance.
This is the variance that can be attributed to differences between the group means.
It is calculated by comparing the mean of each group to the overall mean of all the data points.
The larger the between-group variance, the more likely there are significant differences between the groups.
2. Within-group variance:
This is the variance that can be attributed to differences within each group, i.e., the individual differences among the data points in each group.
It is calculated by comparing the individual data points in each group to their respective group mean.
The smaller the within-group variance, the more likely the groups are homogeneous.
In ANOVA, these two quantities are compared using an F-ratio.
If the between-group variance is significantly larger than the within-group variance, it indicates that there are significant differences between the group means, and the null hypothesis can be rejected.

The new dimensions of the pictures are 2.5 inches by 3.5 inches.
How to calculate dimensions of the new photos?
Chris did image resizing of Career Week, which originally measured 5 inches by 7 inches, by a factor of 1/2. This means that he reduced each dimension of the pictures by half of its original size.
To calculate the new dimensions, he multiplied each original dimension by the scaling factor of 1/2.
If the pictures were resized by a factor of 1/2, it means that each dimension was reduced to half of its original size.
The original dimensions of the pictures were 5 inches by 7 inches.
Resizing each dimension by a factor of 1/2 gives:
5 inches x 1/2 = 2.5 inches
7 inches x 1/2 = 3.5 inches
Therefore, the new dimensions of the pictures are 2.5 inches by 3.5 inches.
This means that the new pictures are significantly smaller than the original ones, which may affect their resolution and quality.

The statement "d ⫮ n if, and only if, d is a common divisor of n and a, for any integer a" is equivalent to saying that d is a divisor of n, and that any other common divisor of n and a must also be divisible by d.
This property is important in number theory and is often used in proofs involving greatest common divisors (GCD) and least common multiples (LCM). By understanding the relationship between d, n, and a and the idea of common divisors, we can gain insight into the properties of numbers and their factors.

Jordan’s credit card has an APR of 10. 59%, compounded monthly. He is required to make a minimum payment of 3. 96% of his current balance every month. At the beginning of March, Jordan had a balance of $628. 16 on his credit card. The following table shows his credit card purchases over the next few months. Month Cost ($) March 50. 81 March 48. 04 April 77. 36 April 32. 40 April 49. 20 May 25. 79 May 79. 39 May 79. 08 If Jordan makes only the minimum monthly payments in March, April, and May, what will his balance be after he makes the minimum payment for May? (Assume that interest is compounded before the monthly payment is made, and that the monthly payment is applied at the end of the month. Round all dollar values to the nearest cent. ) a. $1,094. 10 b. $988. 97 c. $967. 60 d. $1,070. 23.
Answer: To find Jordan's balance after he makes the minimum payment for May, we need to calculate his balance at the end of each month, taking into account his purchases, the interest charged, and the minimum payment made.
In March, Jordan's balance was $628.16 and he made a minimum payment of:
$628.16 x 3.96% = $24.92
His purchases in March totaled $50.81, so his balance after March was:
$628.16 + $50.81 = $678.97
The interest charged in March would be:
$678.97 x (10.59%/12) = $5.72
So his balance after interest was added in March would be:
$678.97 + $5.72 = $684.69
In April, Jordan's balance was $684.69 and he made a minimum payment of:
$684.69 x 3.96% = $27.13
His purchases in April totaled $77.36 + $32.40 + $49.20 = $159.96, so his balance after April was:
$684.69 + $159.96 = $844.65
The interest charged in April would be:
$844.65 x (10.59%/12) = $7.10
So his balance after interest was added in April would be:
$844.65 + $7.10 = $851.75
In May, Jordan's balance was $851.75 and he made a minimum payment of:
$851.75 x 3.96% = $33.77
His purchases in May totaled $25.79 + $79.39 + $79.08 = $184.26, so his balance after May would be:
$851.75 + $184.26 = $1,036.01
The interest charged in May would be:
$1,036.01 x (10.59%/12) = $8.71
So his balance after interest was added in May would be:
$1,036.01 + $8.71 = $1,044.72
Therefore, Jordan's balance after he makes the minimum payment for May would be $1,044.72, which is closest to answer (a) $1,094.10.
Consider a hypothesis test of difference of proportions for two independent populations. Suppose random samples produce r1 successes out of n1 trials for the first population and r2 successes out of n2 trials for the second population. What is the best pooled estimate p for the population probability of success using H0: p1
This pooled estimate provides a common probability of success for both populations under the null hypothesis H0: p1 = p2, and is used in the calculation of the test statistic for the hypothesis test.
To calculate the best pooled estimate p for the population probability of success using H0: p1 = p2, we first need to calculate the individual sample proportions for each population.
The sample proportion for the first population is r1/n1, and the sample proportion for the second population is r2/n2.
Then, we can calculate the pooled estimate p as:
p = (r1 + r2) / (n1 + n2)
This is the weighted average of the sample proportions, where the weight is proportional to the sample size.
Using this pooled estimate p, we can then calculate the test statistic for the hypothesis test of difference of proportions.

Answers in bold:
S9 = 2
i = 20
R = -2
=====================================================
Explanation:
[tex]S_0 = 20[/tex] is the initial term because your teacher mentioned [tex]A_0 = I[/tex] as the initial term.
Then R = -2 is the common difference because we subtract 2 from each term to get the next term. In other words, we add -2 to each term to get the next term.
Here is the scratch work for computing terms S1 through S4.
[tex]\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{1} = S_{1-1} - 2 & S_{2} = S_{2-1} - 2\\S_{1} = S_{0} - 2 & S_{2} = S_{1} - 2\\S_{1} = 20 - 2 & S_{2} = 18 - 2\\S_{1} = 18 & S_{2} = 16\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{3} = S_{3-1} - 2 & S_{4} = S_{4-1} - 2\\S_{3} = S_{2} - 2 & S_{4} = S_{3} - 2\\S_{3} = 16 - 2 & S_{4} = 14 - 2\\S_{3} = 14 & S_{4} = 12\\\cline{1-2}\end{array}[/tex]
Then here is S5 though S8
[tex]\begin{array}{|l|l|}\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{5} = S_{5-1} - 2 & S_{6} = S_{6-1} - 2\\S_{5} = S_{4} - 2 & S_{6} = S_{5} - 2\\S_{5} = 12 - 2 & S_{6} = 10 - 2\\S_{5} = 10 & S_{6} = 8\\\cline{1-2}S_{n} = S_{n-1} - 2 & S_{n} = S_{n-1} - 2\\S_{7} = S_{7-1} - 2 & S_{8} = S_{8-1} - 2\\S_{7} = S_{6} - 2 & S_{8} = S_{7} - 2\\S_{7} = 8 - 2 & S_{8} = 6 - 2\\S_{7} = 6 & S_{8} = 4\\\cline{1-2}\end{array}[/tex]
And finally we arrive at S9.
[tex]S_{n} = S_{n-1} - 2\\\\S_{9} = S_{9-1} - 2\\\\S_{9} = S_{8} - 2\\\\S_{9} = 4 - 2\\\\S_{9} = 2\\\\[/tex]
--------------------
Because we have an arithmetic sequence, there is a shortcut.
[tex]a_n[/tex] represents the nth term
S9 refers to the 10th term because we started at index 0. So we plug n = 10 into the arithmetic sequence formula below.
[tex]a_n = a_1 + d(n-1)\\\\a_n = 20 + (-2)(n-1)\\\\a_n = 20 - 2(n-1)\\\\a_{10} = 20 - 2(10-1)\\\\a_{10} = 20 - 2(9)\\\\a_{10} = 20 - 18\\\\a_{10} = 2\\\\[/tex]
In other words, we start with 20 and subtract off 9 copies of 2 to arrive at 20-2*9 = 20-18 = 2, which helps see a faster way why [tex]S_9 = 2[/tex]
I am a quadrilateral with two pairs of opposite sides always congruent. Who am I?
(square, rhombus, rectangle, parallelogram, kite, isosceles trapezoid, trapezoid)
A quadrilateral with two pairs of opposite sides always congruent is a parallelogram. A parallelogram is a quadrilateral with two pairs of opposite sides that are parallel and always congruent.
In a parallelogram, the opposite angles are also congruent. The rectangle, square, and rhombus are all special types of parallelograms, but they have additional properties that make them unique. A rectangle has four right angles, a square has four right angles and all sides congruent, and a rhombus has all sides congruent but does not require right angles.
Kites, isosceles trapezoids, and trapezoids do not necessarily have two pairs of congruent opposite sides, so they do not fit the description.
