I think you want a relationship between the number of lawns mowed and the income from doing it.

I = income

L = lawns

I = 8.50 * L If the question tells you how many lawns he mowed, just put that in for L

L = 8 means he mowed 8 lawns. This is just a made up number.

I = 8.50 * 8

I = 68 dollars from mowing 8 lawns.

Well, we could make the number of lawns he mowed as 'L'

In this case, the total money that Gavin makes is 8.5L

5. Based on recent results, scores on the SAT test are normally distributed with a mean of 1511 and a standard deviation of 312.
Mekhanik [1.2K]

Answer:

The actual SAT score is 2024.

The equivalent ACT score is 29.49.

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.

SAT score that is in the 95th percentile

Scores on the SAT test are normally distributed with a mean of 1511 and a standard deviation of 312, which means that \mu = 1511, \sigma = 312

95th percentile is X when Z has a pvalue of 0.95, so X when Z = 1.645. The score is:

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

1.645 = \frac{X - 1511}{312}

X - 1511 = 1.645*312

X = 2024

The actual SAT score is 2024.

Equivalent ACT score:

The equivalent ACT score is the 95th percentile of ACT scores.

Scores on the ACT test are normally distributed with a mean of 21.1 and a standard deviation of 5.1, which means that \mu = 21.1, \sigma = 5.1. So

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

1.645 = \frac{X - 21.1}{5.1}

X - 21.1 = 1.645*5.1

X = 29.49

The equivalent ACT score is 29.49.

if the volume of a storage room is 24 cubic feet its length is 3 feet and its width is 2 feet what is the height
viva [34]

Answer:

Step-by-step explanation:

V = L*w*h

L = 3

w = 2

h = ?

V = 24

24 = 2*3 * h       Combine the right

24 = 6* h            Divide both sides by 6

24/6 = 6h/6

4 = h
