Answer:
C
Step-by-step explanation:
40 minutes every day for a week is 40 multiplied by 7, which is 280. Dividing that by 60 is 4 remainder 40, so 4 hours and 40 minutes.
The T-test or T statistical test should be performed to test the given hypothesis: verage time to deliver pizza, once the order is placed, is greater than 25 minutes in the population.
As we know that, a statistical test called a t-test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment truly affects the population of interest or whether two groups differ from one another.
The three t-test used to compare means are the one-sample, two-sample, and paired t-tests. By using the formula
t = (m - μ) / (s/√n)
Where,
t = t-test
m = mean
m - μ = theoretical value
s = standard deviation
n = variable set size

Awnswer:
y=-19x+(the y intercept)
Step-by-step explanation:
y=mx+b
m(slope)=rise/run
(-11,-12) (-8,-21)
-21-12/-8-11
-33/-19
y=-19x+b
(You didn't add what the y intercept was, so you'll have to do that part when you awnswer.) :)
Step-by-step explanation:
When properly solved
In the answer the decimal point should be placed between 6 and 8
