Answer:

the square root of 85 (so 85 is the answer)

Step-by-step explanation:

You can use the pythagorean theorem to find the height. So the sides of the triangle would contain the radius (4/2 = 2) and 9.

so, 2 squared plus 9 squared = 85

I hope this helps!

How does the length of the hypotenuse in a right triangle relate to the lengths of the legs?

STALIN [3.7K]

It holds the legs up. there is a right angle which is the little box in the 90 degree corner:) the hypotenuse is always the longest part on the triangle which you can not simplify:) so the right triangle has legs that you can simplify:)

On a recent day a Euro was equal to about 1.2 American dollars. Write an expression which estimates the number of dollars in x E

JulsSmile [24]

Answer:

d = 1.2e

30 dollars

Step-by-step explanation:

To write an expression, define the variables. E will be the number of euros and d will be dollars.

"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.

This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.

If I have 25 euros then d = 1.2*25 = 30 dollars.

In a sample of 1000 cases, the mean of a certain test is 14 and the standard deviation is 2.5. Assume the distribution to be nor

Maslowich

Answer:

The top 20% of the students will score at least 2.1 points above the mean.

Step-by-step explanation:

When the distribution is normal, we use 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.

The mean of a certain test is 14 and the standard deviation is 2.5.

This means that $\mu = 14, \sigma = 2.5$
