Answer:
4.2 cubic inches
Step-by-step explanation:
Find the diagram attached
Volume of the rectangular pyramid = BH/3
B is the base area
H is the height of the pyramid
Given
Base area = 3.2in * 1.4in
Base area = 4.48sq. in
Height = 2.8in
Volume of the rectangular pyramid = 4.48*2.8/3
Volume of the rectangular pyramid = 12.544/3
Volume of the rectangular pyramid = 4.2 cubic inches
Answer:
(x+9, y+3)
Step-by-step explanation:
The graph shows that T(x, y) = (x+3, y+1).
Application of that transform again gives ...
T²(x, y) = T(T(x, y)) = T(x +3, y +1) = ((x +3)+3, (y+1)+1) = (x+6, y+2)
and again ...
T³(x, y) = T(T²(x, y)) = T(x+6, y+2) = ((x+6)+3, (y+2)+1)
T³(x, y) = (x +9, y +3)
Answer:
a) 0.194
b) $440.8
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $9.40
Standard Deviation, σ = $4.40
Formula:
Standard error due to sampling =
a) P(tips from 40 parties > $400)
Thus, the average pay is
P(x > 10)
Calculation the value from standard normal z table, we have,
b) We have to find the value of x such that the probability is 0.01
Calculation the value from standard normal z table, we have,
Thus, the mean tip is $11.02
Tip for 40 parties =
Thus, he earns $440.8 on the best 1% of such weekends.
