76% of U.S. adults think that political correctness is a problem in America today. You randomly select six U.S. adults and ask them whether they think that political correctness is a problem in America today. The random variable represents the number of U.S. adults who think that political correctness is a problem in America today. Answer the questions below.
Answer:
[tex]E(x) = 4.56[/tex] --- Mean
[tex]s^2 = 1.0944[/tex] --- Variance
[tex]s = 1.0461[/tex] --- Standard Deviation
Step-by-step explanation:
See Comment for missing details
Given
[tex]p = 0.76[/tex] --- proportion
[tex]n = 6[/tex] -- sample
Solving (a): The mean; E(x)
This is calculated as:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 6 * 0.76[/tex]
[tex]E(x) = 4.56[/tex]
Solving (b): The variance; s^2
This is calculated as:
[tex]s^2 = n*p*(1-p)[/tex]
Substitute values for n and p
[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]
[tex]s^2 = 6 * 0.76 * 0.24[/tex]
[tex]s^2 = 1.0944[/tex]
Solving (c): The standard deviation; s
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute value for s^2
[tex]s = \sqrt{1.0944[/tex]
[tex]s = 1.0461[/tex]

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

Calculate the area of this triangle.
17 cm
8 cm
15 cm-
Area - Triangles
Overview
Answer:
There are 3 possible answers because you didn't state which value was base or height.
Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*8)
A = 1/2(120)
A = 60
Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)
A = 1/2(b*h)
A = 1/2(17*8)
A = 1/2(136)
A = 68
Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*17)
A = 1/2(255)
A = 127.5
find the value of f

Emelia earns $8.00 per hour plus a gas allowance of $3.50 per day at her job. How much does Emilia's job pay in a day when she works 5 hours? Write an expression and evaluation for 5 hours.
Answer: Required expression = 8h +3.50
Emilia's job pay $ 43.5 in a day when she works 5 hours.
Step-by-step explanation:
Given: Hourly earning = $8.00
gas allowance per day = $3.50
Pay per day = (Hourly earning ) x (Number of hours ) + (gas allowance per day)
Let h = number of hours
Pay per day = 8h +3.50
If Emily worked for 5 hours, then put h= 5, we get
Pay per day = 8(5) +3.50
= $ 40 +3.50
= $ 43.5
Required expression = 8h +3.50
Emilia's job pay $ 43.5 in a day when she works 5 hours.
