Answer:
The difference in area of the two pizzas is 113.14 inch².
Step-by-step explanation:
Martin ordered a pizza with a 16 inch diameter and Ricky ordered a pizza with a 20 inch diameter.
We have to calculate the approximate difference in area of the two pizzas.
Ara of pizza ordered by Martin =
=
Area of pizza ordered by Ricky =
Difference in area =
=
= 113.14 inch²
The difference in area of the two pizzas is 113.14 inch².
Answer:
Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.

We have the next inequalitythats:
Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.
Answer:
The sample 2 has a lowest value of SE corresponding to the least sample variability.
Step-by-step explanation:
As the value of the sample means and standard deviations are not given, as similar question is found online from which the values of data is follows
The data is as attached with the solution. From this data
Sample 1 has a mean of 34 and a SE of 5
Sample 2 has a mean of 30 and a SE of 2
Sample 3 has a mean of 26 and a SE of 3
Sample 4 has a mean of 38 and a SE of 5
As per the measure of the sample variability is linked with the value of SE or standard error. Which is lowest in the case of sample 2 .
So the sample 2 has a lowest value of SE corresponding to the least sample variability.
