Store one since the 15% is take off 90 dollars which makes it 510
25% means 1/4
divide 268 with 4 and the answer is
67
No because they do not have a common d

Answer:
45,489.6 pounds!
Step-by-step explanation:
To solve this problem, first we need to find the volume of the pool.
We know that the dimensions of the pool are:
Width = 9ft
Length = 18ft
Height = 54in = 4.5 ft
So the volume of the pool is:
Volume = Width x Length x Height = 9ftx18ftx4.5ft = 729ft^3
We know that one cubic foot of water weights about 62.4 pounds. To fill the pool, we will need 729ft^3 of water.
So the weight of the water is:
Weight = 729ft^3 x 62.4 pounds/ft = 45,489.6 pounds!
Answer: the probability that we observe 4 cracks when inspecting a 3 m2 section is 0.034
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r = x represents the number of successes of the event(cracks).
From the information given,
µ = 3 cracks per 1 m² section
It means that for a 3 m² section of the aircraft, the average number of cracks would be 9
the probability that we observe 4 cracks when inspecting a 3 m2 section would be
P(x = 4) = (e^- 9 × 9^4)/4!
P(x = 4) = 0.034
