Answer: x = 111

Explanation: To find the missing angle, you first have to find the sun of the known angles.

75 + 36 = 111

From there you subtract it from 180, because the sun of all angles in a triangle add up to 180 degrees.

180 - 111 = 69

From there, you have the interior angle. The angle you are looking for is equal to the number you had originally found, 111.

You have $83 in your bank account each week you plan to deposit eight dollars from your allowance and $15 from your paycheck the

docker41 [41]

We know that you have 83$ in your bank account.

Okay so what is 15+8=23 So that means you get 23$ per week.

Now what is 83+23=106
106+23=129
129+23=152
152+23=175
Now that was four 23's

That means it would take 4 weeks for you to have 175 dollars in your bank account.
Hope this helped.

A Ski resort tracks the proportion of seasonal employees who are rehired each season. Rehiring a seasonal employee is beneficial

DaniilM [7]

The test statistic z will be equal to -0.946 and it shows that there is no significant difference in the proportion of rehires between full time and part time.

Given sample sizes of 833 and 386 and result of samples 434 and 189.

$n_{1} =833, n_{2}=386$

Proportion of full time=434/833=0.52

Proportion of part time=189/386=0.49.

Difference in proportion =0.52-0.49

$H_{0}:$ TTF- i∈ rho=0

$H_{1}:$ TTF+i∈ rho≠0.

Mean of difference=0.03

Z=(X-μ)/σ

σ= $\sqrt{0.4517/447}$

=0.0317

σ=0.0317

z=(0-0.03)/0.0317

=-0.03/0.0317

=-0.317

p value will be =0.1736.

Because p value is greater than 0.01 so we will accept the null hypothesis which shows that there is no significant difference in the proportions.

Hence there is no significant difference in the proportion of rehires between full time and part time.
