<u>Answer:</u>

The correct answer option is D. 0.42.

<u>Step-by-step explanation:</u>

We are given the results of a survey in which people were asked if they prefer reading books or e-books.

We are to find the marginal frequency of the number of people who prefer to read books.

For that, we will divide the total number of people who prefer reading books by the total number of people surveyed.

Marginal frequency = 105/250 = 0.42

Convert this franction into a percentage 9/12?
kolbaska11 [484]

<span>Hello, Yoloalanis. In order to solve this question that you have just posted, you only have to do a few simple steps. So, We can do this!</span>

<span />Let's start with your fraction. You will first have to change 9/12 into a decimal. In order to do this, you will have to divide the numerator by the denominator. A numerator is also known as the top part of the fraction. A denominator is the bottom part of the fraction. So, when you divide nine by twelve, you get 0.75 as a decimal. Now, you just have to multiply the decimal by 100 or to make it simpler, just move the decimal two places to the right. To sum it all up, you will get 75%.

Hope it helps :)

The volume of the cylinder is 5275 ft and the height is 23 find the diameter please explain this is for school tomorrow
stepan [7]

\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} V=5275\\ h=23 \end{cases}\implies 5275=\pi r^2(23)\implies \cfrac{5275}{23\pi }=r^2 \\\\\\ \sqrt{\cfrac{5275}{23\pi }}=r\implies 15.144\approx r~\hspace{10em}\stackrel{diameter=2r}{d\approx 30.288}

The width of a rectangle is 6 less than half the length. If x represents the length, which equation could be used to find the wi
Shtirlitz [24]

Answer:

C. y=1/2x-6

Step-by-step explanation:

The correct answer is C. y=1/2x-6.

If we are finding 1/2 of the length, and the length is represented by x, than we would have 1/2x.

It also says 6 less than halve of the length, so we would represent that as 1/2x-6, and that shows us the proper equation to find the width.

Hope this helps!
