QUESTION 39.1 POINT
Levart [38]

Answer:

The Z-score when x = 76 is of -0.125, which tells you that x = 76 is 0.125 standard deviations to the left of the mean.

Step-by-step explanation:

Normal Probability Distribution:

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.

X ~ N(77,8).

This means that \mu = 77, \sigma = 8

Z-score when X = 76:

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

Z = \frac{76 - 77}{8}

Z = -0.125

Negative means that its to the left of the mean.

The Z-score when x = 76 is of -0.125, which tells you that x = 76 is 0.125 standard deviations to the left of the mean.

Eric needs a $1,500 loan in order to buy a drone. Which loan option would cost him the MOST in interest?
Mashcka [7]

Answer:

the one that cost the most interest is option B.

Step-by-step explanation:

In order to select the one that costs more we need to apply the data from each one to the formula below:

M = C*r*t

Where M is the interest amount, C is the value of the loan, r is the interest rate and t is the time elapsed. We have:

A)

M = 1500*0.0625*(24/12) = 187.5

B)

M = 1500*0.06*(30/12) = 225

C)

M = 1500*0.04*(36/12) = 180

D)

M = 1500*0.0375*(42/12) = 196.875

Therefore the one that cost the most interest is option B.

A man selling computer parts realizes that when he sells 16 computer parts, his earning is $1700. When he sells 56 computer part
natta225 [31]

We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50

The man will make $3,187.50 if he sells 30 parts.
