For A all your doing is 15/3 which gives u a whole of 5. Then your going to add the 10 to the 5. 10+5=15. For C, your going to divide 3,015 by 15. Then you will get 201. After you will subtract 201 - 186. Then your final answere will be 15. Hope this helped!

hichkok12 [17]

Answer:

The statistic for this case would be given by:

$z=\frac{0.18 -0.1}{\sqrt{\frac{0.1(1-0.1)}{100}}}=2.67$

Step-by-step explanation:

Infromation provided

n=100 represent the random sample selected

X=18 represent the people who rates Pepsi as being "concerned with my health"

$\hat p=\frac{18}{100}=0.18$ estimated proportion of people who rates Pepsi as being "concerned with my health"

$p_o=0.1$ is the value that reference to compare

z would represent the statistic

Hypothesis to test

For this case we can assume that the interest is check if the proportion of people who rates Pepsi as being "concerned with my health" is equal to 0.1 or not , then the system of hypothesis are:

Null hypothesis: $p=0.1$

Alternative hypothesis: $p \neq 0.1$

The satistic for this one sample proportion test is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing the info given we got:

$z=\frac{0.18 -0.1}{\sqrt{\frac{0.1(1-0.1)}{100}}}=2.67$

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

11111nata11111 [884]

Answer:

She earned 1,076 dollars and 25 cents.

Step-by-step explanation:

x = 7.25 * 4,500 / 100

x = 7.25 * 45

x = 326.25

So commission earned is 326.25 $

We need to add this to her base salary for the week, so:

750 + 326.25 = 1, 076.25

Therefore she earned 1,076 dollars and 25 cents.

Hopes this helps ;p

Rae earns $60 for playing music on saturday nights at the local coffee house. she makes an average of $5.25 in tips per hour. wr

insens350 [35]

Okay. So for this equation, she would make $60, plus $5.25 in tips each hour. So for this, she would get $60 + 5.25h. Plug in 4 hours, and she would make $21 off of tips, plus the $60, which brings her up to $81 total. The answer is C.
