She would receive $3500 maximum.

Since she has $10,000 in coverage, the entire $4000 loss is covered. However, the insurance company would only pay her the amount after the deductible has been taken:

What is the volume of the triangular prism shown below?

liberstina [14]

Answer:

Step-by-step explanation:

The volume (V) of the triangular prism is calculated as

V = area of triangular face × length

Area of triangle = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 6 and h = 8, thus

Area = $\frac{1}{2}$ × 6 × 8 = 3 × 8 = 24 units², thus

V = 24 × 20 = 480 units³ → B

The distances male long jumpers for State College jump are approximately normal with a mean of 263 inches and a standard deviati

Effectus [21]

Answer:

His jump was of 272.45 inches

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 263, \sigma = 14$
