What is the length of the side of a right triangle that has a side length of 12ft and a hypotenuse that measures 15ft

Once again, In order to find the length of the hypotenuse, we need to use Pythagorean's Theorm.

This theorm states that a^2+b^2=c^2

a and b are sides, and c is the hypotenuse

12^2 + b^2 = 15^2\\144+b^2 = 225\\b^2 = 81\\\sqrt{b^2} = \sqrt{81}\\b = 9


The other side is 9

Answer: 9 ft


Step-by-step explanation:

 1. To solve this exercise you must apply the Pythagorean Theorem, which is:

a=\sqrt{b^{2}+c^{2}}

Where a is the hypotenuse, and b and c are the other sides of the triangle.

2. Then, when you  solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of  the side of the rigth triangle is:

 b=\sqrt{(15ft)^{2}-(12ft)^{2}}

 b=9ft

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.
