The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 40 to 75 mi

jeka57 [31]

Answer:

0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

$P(X > x) = \frac{b - x}{b - a}$

Uniformly distributed over the interval 40 to 75 minutes.

This means that $a = 40, b = 75$

It is known that the cycle time exceeds 45 minutes

This means that we can use $a = 45$

What is the probability that the cycle time exceeds 50 minutes?

$P(X > 50) = \frac{75 - 50}{75 - 45} = 0.8333$

0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes

7. The largest of the Great Pyramids in Egypt was built with a square base,

strojnjashka [21]

Answer:

Difference between the original and current volumes = 4013140.30 cubic feet

Step-by-step explanation:

Largest pyramid has the square base with one edge = 754 feet

Area of the square base = (Side)²

= (754)²

= 568516 square feet

Volume of the pyramid = $\frac{1}{3}(\text{Area of the base})(\text{Height})$

= $\frac{1}{3}\times 568516\times 481$

= 91152065.3 cubic feet

After erosion,

Area of the base = (745)² = 555025 square feet

Volume of the pyramid = $\frac{1}{3}(555025)(471)$

= 87138925 cubic feet

Difference between the original and current volumes of the pyramid

= 91152065.30 - 87138925

= 4013140.30 cubic feet

Simplify the expression below. Make sure to reduce all fractions. 8sec(x)/-7sec(x)

Sidana [21]

Answer:

- $\frac{8}{7}$

Step-by-step explanation:

Given

$\frac{8secx}{-7secx}$ ← cancel sec x on numerator/ denominator

= $\frac{8}{-7}$

= - $\frac{8}{7}$
