Answer:
5.848 in
Step-by-step explanation:
Divide the piece of cardboard into nine equal squares of side z.
The centre square is the base of the cube.
When you cut out the corner squares and fold up the sides, you will have a cube with edge length z.
The cube must have a volume of 200 in³.
V = z³
200 = z³
z = 2 × 2.924
z = 5.848 in
The edge length of the cube is 5.848 in.
Answer: 90 minutes
Step-by-step explanation:
Area of the side = 15 x 18 = 270 sq. ft.
3 sq. ft take a minute to paint
270 sq. ft. will take 270 / 3
= 90 minutes
Answer:
22 3/4
Step-by-step explanation:
divide 1/4 which is 0.25, then add 3 to that, then multiply it by 7 which is 22.75
then convert it back into a fraction which is 22 3/4
10 gallons are about 38 liters.
Answer:
0.195
0.191
Step-by-step explanation:
Given that :
μ = 4
Using poisson :
P(x) = (e^-μ * μ^x) ÷ x!
P(x = 3) = (e^-4 * 4^3) / 3!
= (0.0183156 * 64) / 6
= 0.1953664
= 0.195
b. What is the probability that he will sell at most 5 policies in two weeks period?
Mean per week = 4
Mean in two weeks = 4 * 2 = 8
P(x ≤ 5) = p(5) + p(4) +... + p(0)
Using the poisson distribution calculator :
P(x ≤ 5) = 0.19124
= 0.191
