Naomi's car exponentially depreciates at a rate of 8% per

Dafna11 [192]

The approximate original price of the car is $23032

<h3>How to determine the original price?</h3>

The given parameters are:

Rate, r = 8%

Price at 4 years old = 16,500

An exponential function is represented as:

y = a(1 - r)^x

Where a represents the initial value

This gives

y = a(1 - 8%)^x

Evaluate

y = a(0.92)^x

At 4 years old, we have:

16500 = a(0.92)^4

Divide both sides by (0.92)^4

a = 23032

Hence, the approximate original price of the car is $23032

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:

$\mu = 263, \sigma = 14$
