Answer:
Step-by-step explanation:
We have been given that Wren’s first display box is 6 inches long, 9 inches wide, and 4 inches high. We are asked to find the volume of display box.
We know that the box is in form of cuboid, so its volume would be length times width times height.
Therefore, the volume of the display box is 216 cubic inches.

Answer:
i) 0.872
ii) 0.300
iii) 0.76
iv) 0.704
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $261.50 per month
Standard Deviation, σ = $16.25
We are given that the distribution of monthly food cost for a 14- to 18-year-old male is a bell shaped distribution that is a normal distribution.
Formula:
a) P(Less than $280)
Calculation the value from standard normal z table, we have,
b) P(More than $270)
P(x > 270)
Calculation the value from standard normal z table, we have,
c) P(More than $250)
P(x > 250)
Calculation the value from standard normal z table, we have,
d) P(Between $240 and $275)
e) Thus, 0.704 is the probability that the monthly food cost for a randomly selected 14- to 18-year-old male is between $240 and $275.
