The XYZ company is seeing its value declining at a rate of 3.2% per year. If the current value is $2,300,000, what will the valu

slega [8]

Given that its value decreases by r = -3.2% (i.e decreasing means that the rate is negative) and that the current value of the company is P = 2,300,000.

The value of the company in n = 5 years is given by

$FV=P(1+r)^n \\ \\ =2,300,000(1-0.032)^5 \\ \\ =2,300,000(0.968)^5=2,300,000(0.8499) \\ \\ =\$1,954,810.81$

lilavasa [31]

$312.50 = p x 0.25 x 25
divided by 25
12.50 = p x 0.25
divide by 0.25
50 = principal

Keenan scored 80 points on an exam that had a mean score of 77 points and a standard deviation of 4.9 points. Rachel scored 78 p

Artemon [7]

Answer:

Keenan's z-score was of 0.61.

Rachel's z-score was of 0.81.

Step-by-step explanation:

Z-score:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Keenan scored 80 points on an exam that had a mean score of 77 points and a standard deviation of 4.9 points.

This means that $X = 80, \mu = 77, \sigma = 4.9$
