Find the value of y

Rainbow [258]

You'll apply the geometric mean formula. The idea is to multiply the two pieces of the hypotenuse: 5*11 = 55

Then apply the square root to get sqrt(55)

The exact answer in terms of radicals or square roots is sqrt(55)

Using a calculator, the approximate answer is sqrt(55) = 7.416198

If your teacher wants you to use a proportion, then one way to do it is to have
11/y = y/5
11*5 = y*y
55 = y^2
y^2 = 55
y = sqrt(55)
y = 7.416198 approximately

Sorry the question before didnt make sense.heres the full pic .

Furkat [3]

Answer:

Step-by-step explanation:

The question is:

Are 3/5 and 6/25 equivalent fractions?

Multiply the first fraction by 5/5:

3/5 * 5/5 = 15/25

3/5 is equivalent to 15/25

15/25 is not equal to 6/25.

The measure of one angle of a right triangle is 28∘ more than the measure of the smallest angle. Find the measure of the smalles

slava [35]

$\begin{gathered} x=\text{measure of the smallest angle} \\ 90+x+(x+28)=180 \\ 90+x+x+28=180 \\ 90+2x+28=180 \\ 2x+118=180 \\ 2x=180-118 \\ 2x=62 \\ x=\frac{62}{2} \\ x=31 \\ \text{The measure of the smallest angle is 31 \degree} \end{gathered}$

The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches. Use the Empiric

maks197457 [2]

Answer: c)[50,60]

Step-by-step explanation:

The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).

We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.

Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.

i.e. about 68% of the heights of students lies between $\text{Mean}\pm\text{Standard deviation}$

i.e. about 68% of the heights of students lies between $55\pm5$

Here, $55\pm5=(55-5, 55+5)=(50,60)$

i.e. The required interval that contains the middle 68% of the heights. = [50,60]

Hence, the correct answer is c) (50,60)
