Answer:
5 pounds
Step-by-step explanation:
the volume of the container = 2*1.5*3.5= 10.5cubic foot.
Density of the content = 0.49 pound per cubic foot.
As already know,
Density = mass/ volume.
therefore, mass = density * volume.
mass of the content = 0.49 * 10.5 =5 pounds approximately
Given:
μ = 200 lb, the mean
σ = 25, the standard deviation
For the random variable x = 250 lb, the z-score is
z = (x-μ)/σ =(250 - 200)/25 = 2
From standard tables for the normal distribution, obtain
P(x < 250) = 0.977
Answer: 0.977

276 divides by 4 = 69
So 3x69 = 207 + 276 = $483
