A survey asks a random sample of 2500 adults in California if they support an increase in the state sales tax from 7.50% to 7.75
Nadusha1986 [10]

Answer:

E(Y) = 750

Step-by-step explanation:

Given

Sample Size = 2500

Percentage = 30%

Required

Calculate Mean of Y

Mean or Expected Value is calculated as thus;

E(Y) = np

Where E(Y) represents the mean

n represents the sample size (or population)

p represents the success probability

n = 2500 ; p = 30%%

p = \frac{30}{100} = 0.3

So,

E(Y) = 2500 * 0.3

E(Y) = 750

Hence, the mean value of Y is 750

What is the solution to the system of equations?
Mrac [35]

Answer:

There is no solution.

Rewrite -2x + y = -6 so it starts with y =...

y = 2x - 6

Substitute that in 2/3x - 1/3y = -2 gives:

2/3x - 1/3*(2x -6) = -2

2/3x - 2/3x + 2 = -2

0 + 2 = -2

This statement is not true, and that means there is no solution.
