10 dergres that is the answer
Answer: 42 - 8x
Step-by-step explanation:
Here is the complete question:
Jessica had $15. She bought 3 apples for x dollars each. Levi had $27 and bought 5 apples for x dollars each. Which expression represents how much money both Jessica and Levi have left altogether?
Select one:
27 – 5x
42 – 8x
12 – 2x
39 – 3x
From the question, Jessica had $15. She bought 3 apples for x dollars each. This means she had:
15 - (3 × x) = 15 - 3x
Levi had $27 and bought 5 apples for x dollars each. Levi will have:
27 - (5 × x) = 27 - 5x
The amount they'll have altogether will be the addition of their amount left. This will be:
15 - 3x + 27 - 5x
= 15 + 27 - 3x - 5x
= 42 - 8x

Answer:
The right answer is:
a.H0: μd = 0; H1: μd > 0
Step-by-step explanation:
The claim that want to be tested is that the sales were significantly increased after the commercial, indicanting that the advertisement campaign was effective.
This claim is usually expressed in the alternative hypothesis as it has to have enough evidence to prove that it is true.
Then, the alternative hypothesis H1 should state that the difference (sales after - sales before) is higher than 0.
The null hypothesis would state that the difference is not significantly different from 0, or, in other words, that the sales are the same before and after and that the variation is due to pure chance.
Then, the null hypothesis H0 would state that the difference is equal to 0.
The right answer is:
a.H0: μd = 0; H1: μd > 0
Because it was being impeached
