Adult : Children = 5 parts : 2 parts
Total parts = 5+2 = 7 parts
1 part of people in the zoo = 105/7 = 15 people
Number of children in the zoo = 15×2 = 30 chidren
Y = 2.2x
to check let’s plug in numbers
6.6 = 2.2(3)
6.6 = 6.6
since it’s true it’s most likely the right answer :)

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
