Question:
Let x denote the amount of gravel sold (in tons) during a randomly selected week at a particular sales facility. Suppose that the density curve has height f(x) above the value x, where
The density curve (the graph of f(x)) is shown in the following figure:
Use the fact that the area of a triangle = 1/2 (base)(height) to calculate each of the following probabilities:
e. The probability that gravel sold exceeds 1/2 ton
f. The probability that gravel sold is at least 1/4 ton
Fantastic news! We've Found the answer you've been seeking!
Step by Step Answer:
To find the probabilities mentioned in parts e and f we will need to calculate the areas under the density curve Because the density curve forms a tri...View the full answer
