3. A vehicle uses 15 gallons of gasoline to travel 13 miles. At this rate, how many miles can the
Tems11 [23]
1. Start by identifying what the question wants so we are looking for miles per 1 gallon.
2. Set up a statement. When the word “per” is being used it relates to a fraction or a ratio. In this question we need to find how many miles a single gallon will give us. So set it up as miles/gallons
3. Plug in your numbers. Now our statement is 13 miles/15 gallons
4. Calculate. So do 13/15 which equals 0.86 miles per 1 gallon.
Tip: always add in words into your calculations. Mainly the units you are using so you can quickly look and know what the units will be. This will help you in upper placement math as well

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
emmasim [6.3K]

Answer:

Tera had the higher z-score, so she should be offered the job.

Step-by-step explanation:

Z- score:

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:

Whoever has the higher z-score should get the job.

Brittany:

Scored 88.3, mean 63.1, standard deviation 14. So

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

Z = \frac{88.3 - 63.1}{14}

Z = 1.8

Alissa:

Scored 236.5, mean 219, standard deviation 25. So

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

Z = \frac{236.5 - 219}{25}

Z = 0.7

Tera:

Scored 7.75, mean 6.66, standard deviation 0.5. So

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

Z = \frac{7.75 - 6.66}{0.5}

Z = 2.18

Tera had the higher z-score, so she should be offered the job.
