A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 40 minutes. The owner has randomly selected 21 customers and delivered pizzas to their homes. What hypotheses should the owner test to demonstrate that the pizza delivery will not be successful

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

Step-by-step explanation:

The hypotheses will be set as follows

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

The null hypothesis is that the mean delivery time is less and equal to 40 minutes.

against the claim

that the mean delivery time is greater than 40 minutes.

40 minutes is taken because the success depends on the factor that if the delivery time is less and equal to 40 minutes then the home delivery service will be successful

But if it is greater than 40 minutes then the home delivery service will not be successful

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

i think the amount would be $140.62
