Answers

Answer 1

The coordinates of the vertices of the image is A'(0, -3), B'(3, -2), C'(1, -1). The correct option is B.

What are coordinates?

Triangle ABC is rotated 180 degrees clockwise about the origin and then reflected across the line y=-x.

We are to find the coordinates of the vertices of the image.

We know that

if a point (x, y) is rotated 180 degrees clockwise, then its co-ordinate changes as follows :

(a, b)   ⇒    (-a, -b).

So, after getting rotated 180 degrees clockwise, the coordinates of the vertices of triangle ABC becomes

A(-3, 0)   ⇒  (3, 0)

B(-2, 3)   ⇒   (2, -3)

C(-1, 1)    ⇒   (1, -1).

Therefore, the correct option is B. A'(0, -3), B'(3, -2), C'(1, -1).

A boy bought 3 pair of socks at $17.50 per a pair and paid with two $50.00 notes. How much change was he given

Answers

The cost of 3 pairs of socks at $17.50 per pair is:

3 x $17.50 = $52.50

The boy paid with two $50.00 notes, which is a total of:

2 x $50.00 = $100.00

To find the change, we need to subtract the cost of the socks from the amount paid:

$100.00 - $52.50 = $47.50

Therefore, the boy was given $47.50 in change.

Suppose you roll a single 6-sided die two times. Assume the two rolls are independent of each other and each of the 6 outcomes are equally likely on each of the two rolls. What would be the probability both rolls are more than 4? Write answer as a decimal written to 2 decimal places.

Answers

The probability of both rolls being more than 4 is 0.25, written to two decimal places.

What is probability?

Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. Probability is calculated by taking the number of outcomes that are favorable to the event divided by the total number of possible outcomes.

Let X1 be the outcome of the first roll and X2 be the outcome of the second roll.
We want the probability that X1 > 4 and X2 > 4.
Since each of the 6 outcomes are equally likely and the two rolls are independent of each other, we can calculate the probability as the product of the probabilities of each event.
The probability of X1 > 4 is 3/6, and the probability of X2 > 4 is also 3/6.
Therefore, the probability that both rolls are more than 4 is:
P(X1 > 4 and X2 > 4) = (3/6) * (3/6) = 0.25
The probability of both rolls being more than 4 is 0.25, written to two decimal places.

Ralph Chase plans to sell a piece of property for ​$160000. He wants the money to be paid off in two ways a ​short-term note at ​11% interest and a​ long-term note at ​8% interest. Find the amount of each note if the total annual interest paid is ​$15350.

Answers

Answer:

Let x be the amount of the short-term note and y be the amount of the long-term note.

We know that the total amount of the two notes is $160,000:

x + y = 160,000

We also know that the total annual interest paid is $15,350:

0.11x + 0.08y = 15,350

To solve for x and y, we can use the first equation to solve for one variable in terms of the other:

y = 160,000 - x

Substitute this expression for y in the second equation:

0.11x + 0.08(160,000 - x) = 15,350

Simplify and solve for x:

0.11x + 12,800 - 0.08x = 15,350

0.03x = 2,550

x = 85,000

Substitute this value for x in the equation y = 160,000 - x to find y:

y = 160,000 - 85,000 = 75,000

Therefore, the amount of the short-term note is $85,000 and the amount of the long-term note is $75,000.

a single rose costs 3$ and a bunch of roses costs 12$.How many times as much does the bunch of roses cost than the single rose?

Answers

The bunch of roses costs $12/$3 = 4 times as much as a single rose.

What is arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a fixed constant number, called the common difference, to the preceding term.

The bunch of roses costs 4 times as much as a single rose.

To see why, we can divide the cost of the bunch of roses by the number of roses it contains. If a bunch of roses costs $12 and contains, say, 4 roses, then each rose in the bunch costs $3. On the other hand, a single rose costs $3 on its own.

Therefore, the bunch of roses costs $12/$3 = 4 times as much as a single rose.

A quadratic function is a sort of second-degree polynomial equation, meaning it has at least two squared element. A quadratic equation's generic form is: [tex]ax^2 + bx + c = 0[/tex] where the variable x and the constants a, b, and c. If the coefficient a were zero, the expression would be linear rather than quadratic. Several ways to solve a quadratic equation, including factoring, squaring the square, and utilising the quadratic formula. The negative numbers or roots of the quadratic equation are the values of x which it make the equation true and are the solutions to the quadratic equation.

given

The factored form of the quadratic function f(x), which has roots of 3 and 7, is as follows:

f(x) = a(x - 3)(x - 7) (x - 7) where "a" stands for a fixed coefficient.

We can utilise the point (1, 12) through which the function passes to determine the value of "a"

12 = a(1 - 3) (1 - 3)(1 - 7)

12 = -24a

a = -1/2

Inputting the value of "a" into the factored form yields the following results:

[tex]f(x) = -1/2(x - 3)(x - 7) (x - 7)[/tex]

By extending this phrase, we get:

[tex]f(x) = -1/2(x^2 - 10x + 21)[/tex]

We need to finish the square before we can transform this into vertex form. To achieve this, add and remove the square of the coefficient of x's half:

[tex]f(x) = -1/2(x^2 - 10x + 25 - 4)[/tex]

If we condense this phrase, we get:

[tex]f(x) = -1/2[(x - 5)^2 - 4][/tex]

b. The number of boxes of chocolate left t hours C(t) = 200 - 0.15t

c. One possible solution is t ≈ 7.546 hours after the store opens.

d. there are 194 boxes of chocolates left.

e. you need to arrive at the store no later than 7.504 hours after it opens.

How to find the number of red roses left ?

a. The proportion (relative frequency) of times an event is anticipated to occur when an experiment is repeated a large number of times under identical conditions is known as the probability of the event.:

[tex]R(t) = 400/2^{t/2}[/tex]

b. Let C(t) be the quantity of boxes of chocolate left t hours after the store opens. At first, there are 200 boxes, of which 15% are purchased every hour. We can therefore write:

C(t) = 200 - 0.15t

c. We must solve the equation R(t) = C(t) in order to determine the time at which the number of boxes of chocolates and the number of roses are equal. We obtain: by substituting the formulas we discovered in parts a and b:

[tex]400/2^{t/2} = 200 - 0.15t[/tex]

Simplifying this equation, we get:

[tex]2^{t/2 + 1} + 0.15t - 400 = 0[/tex]

We can solve this equation numerically, using a calculator or a computer program. One possible solution is t ≈ 7.546 hours after the store opens.

d. At 12:30 in the early evening, which is 3.5 hours after the store opens, we can utilize the recipe we tracked down to some extent b to work out the quantity of boxes of chocolates left:

C(3.5) = 200 - 0.15(3.5) = 194.25

We ought to adjust this solution to appear to be legit with regards to the issue. Since we cannot have a fraction of a box, we can round to the nearest integer and state that there are 194 chocolate boxes remaining.

e. To buy 36 red roses, we need to solve the equation R(t) = 36. Substituting the formula we found in part a, we get:

[tex]400/2^{t/2}= 36[/tex]

Simplifying this equation, we get:

2^(t/2) ≈ 11.111

Taking the logarithm of both sides, we get:

t/2 ≈ log2(11.111)

t ≈ 2 log2(11.111)

Using a calculator, we get:

t ≈ 7.504 hours after the store opens.

Therefore, you must arrive at the store no later than 7.504 hours after it opens in order to purchase 36 red roses.

Answers

The middle 98% of most lengths of pregnancies would fall between 237.5 days and 296.5 days.

What is length?

Length is a measurement of distance or size, usually expressed in terms of feet or meters. It is one of the fundamental units of measurement in the International System of Units (SI). Length is a scalar quantity, meaning that it is measured as a magnitude without direction. Length is typically measured in linear units, such as feet and inches, meters, kilometers, and miles.

This is calculated by taking the mean of 267 days and adding and subtracting 1.5 times the standard deviation of 15 days
(1.5 * 15
= 22.5). Thus,
267 + 22.5

The following recursive algorithm computes factorials.

def fact(n) :

else:
fact(n) = n · fact(n − 1)

Use mathematical induction to prove that fact(n) = n! for all n ∈ N

Answers

By mathematical induction, we've proven that the given recursive algorithm computes factorials correctly, i.e., fact(n) = n! for all n ∈ N.

How to solve

To prove the algorithm using mathematical induction, we'll proceed in two steps: the base case and the inductive step.

Base case: n = 0

By definition, 0! = 1. According to the given algorithm, when n = 0, fact(0) = 1. Therefore, the base case holds, as fact(0) = 0! = 1.

Inductive step:

Assume that the algorithm is correct for some arbitrary non-negative integer k, i.e., fact(k) = k!. We want to show that the algorithm is also correct for k + 1, i.e., fact(k + 1) = (k + 1)!.

According to the algorithm:

fact(k + 1) = (k + 1) * fact(k)

Using the induction hypothesis that fact(k) = k!, we can substitute this into the equation:

fact(k + 1) = (k + 1) * k!

By definition of the factorial function, (k + 1)! = (k + 1) * k!, so:

fact(k + 1) = (k + 1)!

We've shown that if fact(k) = k!, then fact(k + 1) = (k + 1)!. Thus, the inductive step is complete.

Answers

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

What is banquet?

A banquet is a large formal meal that usually involves multiple courses and is served to a group of people on special occasions such as weddings, awards ceremonies, or fundraising events. Banquets often include speeches, presentations, and entertainment, and are typically held in a large venue such as a hotel ballroom, banquet hall, or conference center. Banquets can be hosted for a variety of purposes, such as to honor a special guest, celebrate an achievement, or raise money for a charitable cause.

To create a graph showing the solution region of the system of inequalities representing the constraints of the situation, we can use custom relationships to define the variables and constraints.

Let's define the variables:

Let x be the number of adult guests.

Let y be the number of student guests.

Now, let's write the system of inequalities representing the constraints of the situation:

The total number of guests cannot exceed 125: x + y ≤ 125

The cost of hosting the banquet cannot exceed $3375: 45x + 15y ≤ 3375

To graph this system of inequalities, we can plot the boundary lines of each inequality and shade the region that satisfies all the constraints.

The boundary lines of each inequality are:

x + y = 125 (the line that connects the points (0, 125) and (125, 0))

45x + 15y = 3375 (the line that connects the points (0, 225) and (75, 0))

To find the viable combinations of guests that satisfy all the constraints, we need to shade the region that is below the line x + y = 125 and to the left of the line 45x + 15y = 3375.

The resulting graph should look like this:

The point where the two lines intersect, (75, 50), represents the maximum number of adult guests (75) and the maximum number of student guests (50) that can be invited to the banquet while staying within the budget and venue capacity. Any point within the shaded region represents a viable combination of guests.

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

Find the final amount of a $750 investment after 15 years at 8% interest compounded semiannually, quarterly and daily.

Answers

With given compound interest, the final amount of the investment after 15 years at 8% interest compounded semiannually, quarterly and daily are $2,067.87, $2,094.28, and $2,101.62, respectively.

What is Compound interest?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or the interest earned on both the principal and any previously accrued interest. In other words, interest is computed not only on the original amount of money but also on any past interest gained. The interest generated on the cumulative interest can compound exponentially, resulting in enormous growth of an investment or loan sum over time. Compound interest is computed using a formula that takes the principle amount, interest rate, and compounding frequency into consideration.

Now,

To find the final amount of the investment, we can use the formula for compound interest:

A = P(1 + r/n)ⁿˣ

where:

A = final amount

P = principal (initial investment)

r = annual interest rate

n = times the interest is compounded per year

x = time in years

For semiannual compounding, n = 2 and x = 15:

A = 750(1 + 0.08/2)²*¹⁵= $2,067.87

For quarterly compounding, n = 4 and x = 15:

A = 750(1 + 0.08/4)⁴*¹⁵ = $2,094.28

For daily compounding, n = 365 (assuming no leap years) and x = 15:

A = 750(1 + 0.08/365)³⁶⁵*¹⁵ = $2,101.62

Therefore, the final amount of the investment after 15 years at 8% interest compounded semiannually, quarterly and daily are $2,067.87, $2,094.28, and $2,101.62, respectively.

Answers

a. The decision rule for this hypothesis test is: Reject H0 if the test statistic z is less than -1.645 or greater than 1.645. b. The test statistic for this hypothesis test is:  -2.05.

What is hypothesis?

In statistics, a hypothesis is an assumption or claim about a population parameter that can be tested by collecting and analyzing sample data.

According to given information:

a. The decision rule for this hypothesis test is:

Reject H0 if the test statistic z is less than -1.645 or greater than 1.645.

b. The sample proportion of customers who prefer black teas is:

= 0.41

The population proportion under the null hypothesis is:

p = 0.51

The sample size is:

n = 158

The test statistic for this hypothesis test is:

[tex]z = ( - p) / \sqrt(p * (1 - p) / n)[/tex]

[tex]= (0.41 - 0.51) / \sqrt(0.51 * 0.49 / 158)[/tex]

[tex]= -2.05[/tex]

c. The test statistic z of -2.05 is less than the critical value of -1.645, so we can reject the null hypothesis H0. At the 0.10 significance level, there is enough evidence to suggest that the proportion of customers who prefer black teas is not 0.51, and the manager of Tea for Us should consider adjusting their stock orders accordingly.

Consider two points A(0,0) and B(1, 1) on a Cartesian plane. The equation of the axis of the segment AB is: A. y = 1 2 −  B. y = 2 −  C. y = 1 −  2 D. y = 1 −  E. y = 1 −  2

Answers

So, the equation of the axis of the segment AB is (A) y = 1/2 - x/2.

What is slope?

In mathematics, slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for every unit change in the independent variable.

The slope of the line passing through points A and B can be calculated as follows:

slope = (change in y) / (change in x) = (1-0) / (1-0) = 1/1 = 1

The equation of a line in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.

To find the y-intercept, we can use point A (0,0) and substitute the slope value.

y = mx + b

0 = 1(0) + b

b = 0

Therefore, the equation of the line passing through points A and B is:

y = 1x + 0

Simplifying, we get:

y = x

So, the answer is (A) y = 1/2 - x/2. However, this is not one of the given answer choices. We can also write the equation in point-slope form as y - y1 = m(x - x1) using point A, which gives:

y - 0 = 1(x - 0)

y = x

This confirms our earlier answer.

Answers

The value of x that satisfies the equation is x = -3. So the answer is x = −3, or "x is equal to negative 3"

What is the value of xin the equation, 5(x+2)+4x=6x+1?

To solve the equation, we can begin by simplifying both sides using the distributive property and combining like terms:

5(x+2) + 4x = 6x + 1

5x + 10 + 4x = 6x + 1

9x + 10 = 6x + 1

Next, we can isolate the variable x on one side of the equation by subtracting 6x and 1 from both sides:

9x + 10 - 6x - 1 = 0

3x + 9 = 0

3x = -9

x = -3

Therefore, the value of x that satisfies the equation is x = -3. So the answer is x = −3, or "x is equal to negative 3"

The brain volumes (cm³) of 20 brains have a mean of 1128.4 cm³ and a standard deviation of 125.9 cm³. Use the
given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or
significantly high. For such data, would a brain volume of 1360.2 cm³ be significantly high?
Significantly low values are cm³ or lower.

Answers

Step-by-step explanation:

The range rule of thumb states that for data with a roughly bell-shaped distribution, about 68% of the data falls within one standard deviation of the mean, about 95% falls within two standard deviations, and about 99.7% falls within three standard deviations.

Given that the standard deviation is 125.9 cm³, one standard deviation above the mean would be 1128.4 + 125.9 = 1254.3 cm³, and one standard deviation below the mean would be 1128.4 - 125.9 = 1002.5 cm³.

Thus, significantly low values would be 1002.5 cm³ or lower, and significantly high values would be 1254.3 cm³ or higher.

Since 1360.2 cm³ is higher than 1254.3 cm³, it would fall outside the range of one standard deviation above the mean and can be considered significantly high based on the range rule of thumb.

What is frequency table?

A frequency table is a statistical tool used to organize data by counting the number of occurrences of each unique item or value in a dataset. It is a way to summarize and present data in a concise and structured manner, making it easier to understand and analyze.

For example, if you have a dataset of students' grades, you can create a frequency table by listing all the possible grades (e.g., A, B, C, D, F) and counting how many times each grade appears in the dataset. The resulting table will show the frequency or number of times each grade was earned by the students.

Frequency tables can be used to display both qualitative (categorical) and quantitative (numerical) data. For categorical data, the frequency table will show the count or percentage of occurrences of each category. For numerical data, the frequency table will show the number of times each value or range of values appears in the dataset

Based on the data you provided, here is a frequency table for the movie genres:

Movie Number of students

Write 80cm to 2km as rate

Answers

One per 2,500 can be used to represent the rate of 80cm to 2km.

Writing measures as a rate.

To write 80cm to 2km as a rate, we need to convert the units to the same system. We can convert 80cm to kilometers by dividing by 100,000 (since there are 100,000 centimeters in a kilometer):

80 cm/100,000 = 0.0008 km

Now we can express the rate as:

0.0008 km per 2 km

Or we can simplify it by dividing both the numerator and denominator by 0.0008:

1 per 2,500

Therefore, 80cm to 2km can be expressed as a rate of 1 per 2,500.

The answer is Option B; Yes. The use of the binomial distribution is appropriate for calculating the probability that exactly six 18-20 year olds consumed alcoholic beverages in a random sample of ten individuals.

Why is the use of binomial distribution effective in this case?

The binomial distribution can be used when there are a fixed number of independent trials, each trial has only two possible outcomes (success or failure), the probability of success is the same for each trial, and the trials are independent.

In this case, we have a fixed number of ten independent trials (i.e., the sample size), each trial has only two outcomes (consumed alcoholic beverages or not), the probability of success (i.e., consuming alcoholic beverages) is the same for each trial (68.2%), and the trials are independent (i.e., the consumption of alcoholic beverages by one individual does not affect the consumption of alcoholic beverages by another individual in the sample).

Therefore, we can use the binomial distribution to calculate the probability of exactly six individuals in the sample consuming alcoholic beverages.
