A 2-month membership to the
gym costs $125. Jim would like
to be a member for 8
months. What is the total
amount he will pay for 8
months?

Answers

A two month membership costs $125, which means Jim will pay $125 every two months he is a member at the gym. So instead of multiplying $125 by 8, we multiply it by 4 since he only has to pay every 2 months.
125•4= 500
Jim will pay $500 for 8 months of a gym membership

Angela wants to use a one-sample zzz interval to estimate what proportion of employees at her large corporation are satisfied with their benefits. She plans on using a confidence level of 90\%90%90, percent, and she wants her margin of error to be no more than \pm 5\%±5%plus minus, 5, percent.

Answers

Answer:

Step-by-step explanation:

It's 271 on Khan Academy

The sample space size that Angela wants to use for the employees who are satisfied with their benefits is. 271

What is margin of error?

In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.

Given that,

[tex]\^p[/tex] = 0.5

1 - [tex]\^p[/tex] = 1 - 0.5= 0.5

margin of error = E = 5% = 0.05

At 90% confidence level

= 1 - 0.90 = 0.10

0.10/2 =0.05

Z/2 = 1.645 ( Using z table )

Sample size = n = (Z/2 / E)² x (1 - [tex]\^p[/tex])²

= (1.645 / 0.05)² * 0.5 x 0.5

=270.6

Sample size = 271

The required sample size is 271.

Solve the system of linear equations by elimination -x+y=4;x+3y=4

Answers

Answer:

the solution is (-8, 4)

Step-by-step explanation:

Let's use the addition/subtraction method here to eliminate one variable:

-x+y=4

x+3y=4

Combining these two equations results in

4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:

x + 3(2) = 4, or x = -2.

Then the solution is (-8, 4)
