We know that there was $5 left over, so we can set up an equation to solve for the price per water bottle:

50 - 10x = 5\\-10x = -45\\x = 4.50


Each water bottle cost $4.50

This pentagon can be split into three triangles, so the total for this pentagon is 540°. Add up all angles to equal 540°.

x= unknown angle

90° + 107° + 144° + 138° + x= 540°
479 + x= 540
subtract 479 from both sides
x= 61

CHECK:
90 + 107 + 144 + 138 + 61= 540
540= 540

ANSWER: x= 61°

Hope this helps! :)

An aptitude test has a mean score of 80 and a standard deviation of 5. The population of scores is normally distributed. What pr
konstantin123 [22]

Answer:

2.28% of tests has scores over 90.

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 = 80, \sigma = 5

What proportion of tests has scores over 90?

This proportion is 1 subtracted by the pvalue of Z when X = 90. So

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

Z = \frac{90 - 80}{5}

Z = 2

Z = 2 has a pvalue of 0.9772.

So 1-0.9772 = 0.0228 = 2.28% of tests has scores over 90.
