Answer:
The 12'' one.
Step-by-step explanation:
The crust is at the perimeter of the pizza, and the pizza is a circle, so we just need to calculate the perimeter of the different pizza sizes, and see which one has a perimeter of 37.68 in.
First, you should remember that for a circle of radius R, the perimeter is:
P = 2*3.14*R
(notice that the measures in the image are the diameters of the pizzas, and the radius is half of the diameter)
The radius that we need to have if we want a perimeter of 37.68 in is given by:
P = 37.68 in = 2*3.14*R
(37.68 in)/(2*3.14) = R = 6 inches.
Then we need a pizza of 6 inches (or a diameter of 2*6 inches = 12 inches)
Then the pizza that Ms. Van Rock should get is the 12 inch one.
Answer:
4 star fruit.

Answer:
This statement can be made with a level of confidence of 97.72%.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8.1 mm
Standard Deviation, σ = 0.5 mm
Sample size, n = 100
We are given that the distribution of thickness is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:

P(mean thickness is less than 8.2 mm)
P(x < 8.2)
Calculation the value from standard normal z table, we have,
