Answer 1

Answer:

[tex] \frac{4}{3} \times \pi \times {21}^{3} = 38772.719999383[/tex]

Answer 2

Exact Volume =  12348pi

Approximate Volume =  38772.72   (when using pi = 3.14)

Units for the volume are in cubic inches

====================================================

Explanation:

The cube has a side length of 42 inches.

Because the sphere is as large as possible, yet fully contained in the box, this means the diameter of the sphere is 42 inches.

If the diameter is 42, then the radius is half that at 21.

Plug r = 21 into the formula below to compute the volume of the sphere

V = (4/3)*pi*r^3

V = (4/3)*pi*21^3

V = (4/3)*21^3*pi

V = 12348pi  .... exact volume

If we use the approximation pi = 3.14, then we would get,

V = 12348*pi

V = 12348*3.14

V = 38772.72 .... approximate volume

The units for the volume are in cubic inches. If you need more accuracy for the approximate volume, then use more decimal digits of pi.

Answers

Answer:

B) 1.15x, adding 15% to the cost of haircut is same as to multiply cost by 1.15

Step-by-step explanation:

Given expression = x + 15% of x

x + (15/100) x = x + 0.15x

= (1+ 0.15) x = 1.15x

15% = 0.15 , added to x = 1.15x

The values are 155 degrees, 5y degrees, and 13x degrees. find the values of x and y

Answers

Answer:

y = 5

x = 5

Step-by-step explanation:

find the complete question in the attached image

the angle opposite 5y is also 5y. this is because alternate angles are equal

180 = 155 + 5y

5y = 180 - 155

5y = 25

y = 5

the sum of 5y and 13x is equal to 90

this is because the sum of angle on a straight line is equal to 180 and one of the angle on the straight line is already equal to 90 . so, 90 (180 - 90)

5y + 13x = 90

25 + 13x = 90

13x = 90 - 25

13x = 65

x = 5

The number of wins in a season for 32 randomly selected professional football teams arelisted below. Construct a 90% confidence interval for the true mean number of wins in a season.




Mean(x) = sum of 32 observations / 32 = 7.97



Standard deviation( sd )=2.62



Sample Size(n)=32



Confidence Interval = [ 7.97 ± Z a/2 ( 2.62/ Sqrt ( 32) ) ] = [ 7.97 - 1.64 * (0.4632) , 7.97 + 1.64 * (0.4632) ] = [ 7.2,8.7 . What are the steps used to solve this? How did they find their Standard Deviation? Also what does the Z stand for in the confidence interval?

Answers

Answer:

A)CI 90 % = [ 7,2103 ;  8,7297]

B) s = √ ∑(xi - xp)²/n-1

c) z is the score for the given significance level in this case is 1,64

Step-by-step explanation:

For a confidence Interval of 90%, the significance level is α = 10 %

α = 0,1     α/2 = 0,05  and from z-table we find  z(c) for 0,05   z(c) = 1,64

CI 90 % = [ x  ±  z(c) * s/√n ]

CI 90 % = [ 7,97 ±  1,64 * 2.62/√32]

CI 90 % = [ 7,97 ± 0,7597]

CI 90 % = [ 7,2103 ;  8,7297]

B) To calculate the standard deviation of the sample the equation is:

s = √ ∑(xi - xp)²/n-1

xi - xp  is the difference between each one of the elements of the sample

xp is the mean or average of the elements of the sample and n is the sample size

Cody purchased a car for $4500 that will depreciate 28% a year. Write an exponential growth/decay equation that represents the value of Cody's car overtime. How much will the car be worth in 15 years? Round to the nearest cent.

Answers

Answer:

$32.60

Step-by-step explanation:

This question has to to do with exponential decay. The formula is given as:

y = a(1 - r)^x

y = Value of the material after x years

a = Initial value of the material

x = Time in years

r = rate of depreciation or decay

Therefore,

y = 4500 × (1 - 0.28)¹⁵

y = 4500 × 0.72¹⁵

y = $32.598675906

y = Approximately = $32.60

Therefore the of the car after 15 years = $32.60

Where t represents the number of years since 2010.

The population of Arlington High is increasing. Because b > 1.

Then the population of Arlington High school after 29 years will be

P(A) = 7/20 P(B) = 7/20 P(A or B) = 49/80, P(A and B)= ?​

Answers

Answer:

P(A and B) = 7/80

Step-by-step explanation:

The given values of the probabilities of the different events are;

P(A) = 7/20

P(B) = 7/20

P(A or B) = 49/80

P(A and B) = Required

We have by probability theory for any event;

P(A or B) = P(A) + P(B) - P(A and B)

Therefore;

P(A and B) = P(A) + P(B) - P(A or B)

Plugging in the values gives;

P(A and B) = 7/20 + 7/20 - 49/80 = 7/80

∴ P(A and B) = 7/80

What is the percent increase or decrease between $7.80 and $6.63?​

Answers

It is a 15% decrease.

Amount One: $7.80
Amount Two: $6.63

You’re looking for what percent of 7.80 is 6.63.

$7.80 * X = $6.63.
X = $6.63/$7.80
X = .85

So $6.63 is 85% of $7.80.

Percents are out if 100, so if you want to know what the percent difference is, subtract 85% from 100%.

100% - 85% = 15%.

As you’re going form $7.80 to $6.63, the number is getting smaller so it’s a decrease. Overall, it’s a 15% decrease from $7.80 to $6.63.
