At Kennedy High School, the probability of a student playing in the band is 0. 15. The probability of a student playing in the band and playing on the football team is 0. 3. Given that a student at Kennedy plays in the band, what is the probability that they play on the football team?

Answers

Answer 1

The probability that a student at Kennedy High School plays on the football team given that they already play in the band is 2/1 or simply 2.

To solve this problem, we can use conditional probability. We want to find the probability that a student plays on the football team given that they already play in the band.

Let's use the formula for conditional probability:

P(Football | Band) = P(Football and Band) / P(Band)

We know that P(Band) = 0.15, and P(Football and Band) = 0.3.

So,

P(Football | Band) = 0.3 / 0.15

Simplifying, we get:

P(Football | Band) = 2

Therefore, the probability that a student at Kennedy High School plays on the football team given that they already play in the band is 2/1 or simply 2.

Note: This answer may seem unusual because probabilities are typically expressed as fractions or decimals between 0 and 1. However, in this case, we can interpret the result as saying that students who play in the band are twice as likely to also play on the football team compared to the overall population of students.

To the nearest dollar, how much did the business initially invest in 1991?

Answers

To the nearest dollar, the business initially invested approximately $3,449 in 1991.

To determine the initial investment in 1991, we can use the formula F = P(1 + R/100)^T, where F is the final amount, P is the initial investment amount, R is the annual interest rate, and T is the time in years.

In this case, F = $4,000 (the amount in the account at the end of 1996), R = 3% (the annual interest rate), and T = 5 years (1996 - 1991). We need to solve for P, the initial investment amount.

First, let's rewrite the equation: P = F / (1 + R/100)^T

Now, we can plug in the known values: P = 4000 / (1 + 3/100)^5

Next, we calculate the denominator: (1 + 0.03)^5 = 1.159274

Then, we divide the final amount by the denominator to find the initial investment: P = 4000 / 1.159274

Lastly, rounding to the nearest dollar, we get: P ≈ $3,449

So, the business initially invested approximately $3,449 in 1991.

The area of a rug is 108 square feet and the length it it’s diagonal is 14 feet. what are the length and width of the rug. write a system of equations tk answer this equation

Answers

The system of equation is 7.71 feet, under the condition the area of a rug is 108 square feet and the length it it’s diagonal is 14 feet.

Now to solve this problem, we can use the formula for the area of a rectangle which is A = L x W . Therefore, we can write the equation 108 = L x W

Now the length of the diagonal is 14 feet. We can use this information to write another equation using the Pythagorean theorem which states that for any right triangle with legs of length a and  b  and hypotenuse of length c ,
a² + b² = c²
Since a rectangle is made up of two right triangles, we can use this theorem to find the length and width of the rectangle.

Let us assume the length of the rug L and the width of the rug  W

L²+ W² = 14²

We have two equations with two unknowns

108 = L x W
L² + W² = 14²

We can solve for one variable in terms of another using substitution. From the first equation,

W = 108 / L

Substituting this into the second equation gives:


L² + (108 / L)² = 14²
L² - 196L² + 11664 = 0


This is a quadratic equation in terms of  L². We can solve for L²  


L² = (196 ± √(196² - 4 x 11664)) / 2
L² = (196 ± √(38416)) / 2
L² = (196 ± 196) / 2


Taking the positive root gives:

L² = 196

So:

L = √(196) = 14

Substituting this back into one of our original equations gives:

W = 108 / L
= 108 / 14
≈ 7.71

Therefore, the length of the rug is 14 feet and its width is approximately 7.71 feet.

One measure of student success for colleges and universities is the percent of admitted students who graduate. Studies indicate that a key issue in retaining students is their performance in so-called gateway courses. These are courses that serve as prerequisites for other key courses that are essential for student success. One measure of student performance in these courses is the DFW rate, the percent of students who receive grades of D, F, or W (withdraw). A major project was undertaken to improve the DFW rate in a gateway course at a large midwestern university. The course curriculum was revised to make it more relevant to the majors of the students taking the course, a small group of excellent teachers taught the course, technology (including clickers and online homework) was introduced, and student support outside the classroom was increased. The following table gives data on the DFW rates for the course over three years. In Year 1, the traditional course was given; in Year 2, a few changes were introduced; and in Year 3, the course was substantially revised.


Year DFW Rate Number of Students Taking Course


Year 1 42. 1% 2408


Year 2 24. 3% 2325


Year 3 19. 4% 2126


1. Do you think that the changes in this gateway course had an impact on the DFW rate? (Use α = 0. 1. )


2. State the null and alternative hypotheses.


3. State the Ï2 statistic, degrees of freedom, and the P-value.

Answers

Yes. The null hypothesis is that the changes in the course did not have a significant impact on the DFW rate. The chi-squared statistic is 44.63, with 2 degrees of freedom, and the p-value is less than 0.001.

1. Yes, it is likely that the changes in the gateway course had an impact on the DFW rate, as the rate decreased from 42.1% in Year 1 to 19.4% in Year 3.

2. The null hypothesis is that the changes in the course did not have a significant impact on the DFW rate, while the alternative hypothesis is that the changes did have a significant impact on the rate.

3. The chi-squared statistic is 44.63, with 2 degrees of freedom, and the p-value is less than 0.001. This indicates that there is a significant relationship between the year the course was given and the DFW rate, providing evidence to reject the null hypothesis in favor of the alternative hypothesis that the changes made to the course had a significant impact on the DFW rate.

The p-value of less than 0.001 indicates strong evidence against the null hypothesis, as it is less than the significance level of 0.1.

What is the minimum surface area of a box whose base is a square and with no top that holds 32 cm³. a 16 b 32 c 64 d 48

Answers

The minimum surface area of the box is 68 cm², which corresponds to option (d).

How to calculate the surface area of box?

Let the side length of the square base be x and the height of the box be h. Then, we have:

Volume of the box = x²h = 32

h = 32/x²

The surface area of the box is given by:

S = x² + 4(xh) = x² + 4x(32/x²) = x² + 128/x

To find the minimum surface area, we can differentiate S with respect to x, set the derivative equal to zero, and solve for x:

dS/dx = 2x - 128/x² = 0

2x = 128/x²

x⁴ = 64

x = 2 cm

Note that we need to check that this critical point gives us a minimum surface area. We can do this by checking the second derivative:

d²S/dx² = 2 + 256/x³

d²S/dx² at x = 2 is positive,

indicating that this critical point gives us a minimum surface area.

Substituting x = 2 in the equation for S, we get:

S = 2² + 128/2 = 4 + 64 = 68

Therefore, the minimum surface area of the box is 68 cm², which corresponds to option (d).

Stacy and clinton are setting up the community center for a freshman orientation. they set up 8 rectangular tables with 6 chairs each and 5 round tables with 4 chairs each. the chairs are randomly numbered starting with 1 and the freshman will be randomly assigned a seat number.
what is the probability that the first freshman to arrive will be seated at a round table?
a 1/20
b 12/17
c 5/17
d 5/13

Answers

"The probability that the first freshman to arrive will be seated at a round table is (5/13)."

To calculate the probability, we need to determine the total number of seats and the number of seats at round tables.

There are 8 rectangular tables with 6 chairs each, so the total number of seats at rectangular tables is 8 * 6 = 48.

There are 5 round tables with 4 chairs each, so the total number of seats at round tables is 5 * 4 = 20.

The total number of seats in the community center is 48 + 20 = 68.

The probability of the first freshman being seated at a round table is the number of seats at round tables (20) divided by the total number of seats (68), which gives us 20/68 = 5/17.

Therefore, the correct answer is option C: 5/17.

In conclusion, the probability that the first freshman to arrive will be seated at a round table is 5/17. This is obtained by dividing the number of seats at round tables by the total number of seats in the community center.

A large box of chocolates has a width that is 2 times the height of the box and a length that is 1. 5 times the width of


the box. Each of the 48 chocolates rests in a cube with a side length of 1 inch

Answers

Let's start by using algebra to represent the relationships between the dimensions of the box:

   Let h be the height of the box.    Then the width of the box is 2h (since it is 2 times the height).    And the length of the box is 1.5 times the width, so it is 1.5(2h) = 3h.

So the dimensions of the box are: height = h, width = 2h, length = 3h.

Now let's find the volume of the box:

   Volume = height x width x length    Volume = h x 2h x 3h    Volume = [tex]6h^3[/tex]

Since we know that each chocolate rests in a cube with a side length of 1 inch, the volume of each chocolate is [tex]1^3 = 1[/tex] cubic inch. So the total volume of all 48 chocolates is 48 cubic inches.

Therefore, we can set up an equation to solve for h:

  [tex]48 = (6h^3) / (1 cubic inch/chocolate)[/tex]

[tex]48 = 6h^3[/tex]

[tex]8 = h^3[/tex]

   h = 2

So the height of the box is 2 inches, the width is 4 inches (since it is 2 times the height), and the length is 6 inches (since it is 1.5 times the width).

To check our work, we can calculate the volume of the box:

   Volume = height x width x length

   Volume = 2 x 4 x 6

   Volume = 48 cubic inches

This matches the total volume of all  48 chocolates, so we can be confident in our answer.

Statement #3 is incorrect. To correct the statement:

The box plot does not provide information on the number of days of data collected.

The box plot, also known as a box-and-whisker plot, is a graphical representation of the distribution of a dataset. It displays information about the median, quartiles, and possible outliers.

However, the box plot itself does not directly provide information on the number of days of data collected.

The main components of a box plot include:

Median: This is the line inside the box that represents the middle value of the dataset. It divides the dataset into two equal halves, with 50% of the data falling below the median and 50% above it.

Quartiles: The box in the plot represents the interquartile range (IQR) of the data. The lower edge of the box corresponds to the first quartile (Q1), which is the 25th percentile. The upper edge of the box corresponds to the third quartile (Q3), which is the 75th percentile. The IQR represents the range of the middle 50% of the data.

Whiskers: These are the lines extending from the box. Typically, the whiskers extend to the smallest and largest observations within a certain range, often 1.5 times the IQR. Values outside this range are considered potential outliers and are represented as individual points beyond the whiskers.

The box plot can provide valuable information about the spread, skewness, and potential outliers in a dataset. However, it does not directly convey information about the number of days of data collected. To determine the number of days, one would need to refer to the raw data or other accompanying information.

Projectile motion. the height, y metres, of a ball after it has been hit can be modelled by the equation y = -1/8x²+x+c, where x is the horizontal distance travelled by the object in metres and c is a constant. (i) given that the maximum height attained by the ball is 2.4 metres, find the value of c and the corresponding horizontal distance travelled by the ball.​

Answers

The value of c is 0.4 and  the corresponding horizontal distance travelled by the ball is 4 meters.

How to solve projectile equations?

We are given the projectile equation:

y = -1/8x² + x + c

To find the value of c, we can use the fact that the maximum height attained by the ball is 2.4 meters. The maximum height occurs at the vertex of the parabola, which is given by:

x = -b/2a

where a = -1/8 and b = 1.

Therefore,

x = -(1)/(2*(-1/8)) = 4

So, the corresponding horizontal distance travelled by the ball is 4 meters.

Now, we can use the maximum height attained by the ball to solve for c.

y = -1/8x² + x + c

Substituting x = 4 and y = 2.4, we get:

2.4 = -1/8(4)² + 4 + c

2.4 = -1/8(16) + 4 + c

2.4 = -2 + 4 + c

c = 0.4

Therefore, the value of c is 0.4.

dP(q)/dq = 65 - (0.12q + 37)
0 = 65 - 0.12q - 37

Solve for q:

0.12q = 28
q = 28 / 0.12
q ≈ 233.33

Since the number of cars must be a whole number, we can round q to the nearest integer. Therefore, the service should wax approximately 233 cars daily to maximize profit.

Imagine some colored blocks are laid out in a row: three red, two blue, three red, two blue and so on. If there are 65 colored blocks, how many would be red?


A. 52


B. 39


C. 26


D. 13

Answers

There are 39 red blocks out of 65 total blocks.

To solve this problem, we need to find the total number of blocks in each repeating pattern. The pattern is three red blocks followed by two blue blocks. So in each pattern, there are five blocks total.

To find the number of red blocks in 65 total blocks, we need to figure out how many times the pattern repeats. We can do this by dividing the total number of blocks (65) by the number of blocks in each pattern (5):

65 ÷ 5 = 13

So the pattern repeats 13 times.

In each pattern, there are three red blocks. So to find the total number of red blocks, we need to multiply the number of red blocks in each pattern (3) by the number of times the pattern repeats (13):

3 x 13 = 39

Therefore, there are 39 red blocks out of 65 total blocks.

The correct answer is option B.

How to find the product of two matrices?

A matrix (plural matrices) is a set of numbers arranged in rows and columns so as to form a rectangular array.

The number of rows of a matrix can be determined by counting from top to bottom and the number of columns can be determined by counting from left to right.

The product (multiplication) of matrices C and D is:

CD = C * D

[tex]CD = \left[\begin{array}{ccc}2\\9\\4\end{array}\right] * \left[\begin{array}{ccc}-3&2&-1\\\end{array}\right][/tex]

To get the product, multiply each row by the column. That is:

2 * (-3) = -6

9 * 2 = 18

4 * (-1) = -4

[tex]CD = \left[\begin{array}{ccc}-6&18&-4\\\end{array}\right][/tex]

1. blinko is a game in which three dice are rolled. to win the game, a player must
roll triples – that is, three of the same number. you roll the dice 20 times.
a. verify that the situation is binomial. (8points)
b. out of 20 rolls, what is the probability you win exactly 4 times? show your
work using the formula for binomial probability. (6 points)
c. what is the probability that you win at least 3 times? (6 points)
d. what is the mean number of wins in 20 rolls of the dice?

Answers

a) It is verified that the situation is binomial

b. Probability of exactly coining 4 times is 1.83 × 10⁻³

c. Probability of winning atleast 3 times is 0.0234

d. Mean number of wins is 0.555

The total number of outcomes per toss is 6×6×6=216

a) Number of trails n = 20

Probability of win P = 6/216 = 1/36

Probability of lost Q = 1 - P

= 1 - 1/36

= 35/36

The outcome has two possibilities with P = 1/36, Q = 35/36  and with n = 20 times. Hence, it is binomial.

(B) Probability of exactly coining 4 times

[tex]P= C^{20}_{4} P^4Q^{16}[/tex]

= 4845 × (1/36)⁴ × (35/36)¹⁶

= 1.83 × 10⁻³

(C) Probability of winning atleast 3 times

[tex]P= 1-C^{20}_{0} P^0Q^{20}-C^{20}_{1} P^1Q^{19}-C^{20}_{2} P^2Q^{18}[/tex]

= 1 - 1 × (1/36)⁰ × (35/36)²⁰ - 20 × (1/36)¹ × (35/36)¹⁹ - 190 × (1/36)² × (35/36)¹⁸

= 1 - 0.5692 - 0.3252 - 0. 0882

= 0.0234

(D) Mean number of wins = nP

= 20 × (1/36)

= 0.555

a) It is verified that the situation is binomial

b. Probability of exactly coining 4 times is 1.83 × 10⁻³

c. Probability of winning atleast 3 times is 0.0234

d. Mean number of wins is 0.555.

What is logarithm function?

Since they enable us to convert an exponential equation into a logarithmic equation and vice versa, logarithmic functions are employed to solve equations involving exponents. They are also used in a variety of disciplines, including science, finance, and engineering.

Given equation:

g(x) = f(x + 4) + 8.

f(x) → f(x + 4)

Horizontal translation less 4 unit.

(x, y) → (x - y), y

f(x, y) + 8

Vertical translation up 4 unit.

(x, y) → (x, y + d)

f(x)

Vertical Asymptote x = 0,

f(x + 4) + 8

Vertical Asymptote x+ 4 = 0

x = -4

Therefore, the features of function gif g(x) = f(x + 4) + 8 is vertical asymptote of r = -4.
