Evgen [1.6K]
<span>We have to calculate the length of the missing side.
Use the Pythagorean theorem:

a^2+32^2=58^2\\\\a^2+1024=3364\ \ \ |-1024\\\\a^2=2340\to a=\sqrt{2340}\\\\a=\sqrt{36\cdot65}\\\\a=6\sqrt{65}

\cos x=\dfrac{6\sqrt{65}}{58}=\dfrac{3\sqrt{65}}{29}

I think. Your answers to choice are wrong.

Last Month, Levi had written 125 words of his book. This month,he is up to 12,580 words. About how many times more words has he
VladimirAG [237]

Answer:

He has written about 100 times as many words.

Step-by-step explanation:

In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.

12,580 - 125 = 12,455

Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.

12,455/125 = 99.64 times more, or rounded, about 100 times more.

Evaluate for x = 2.<br><br> (12x + 8)<br> 4 <br> A) 4 <br> B) 5 <br> C) 6 <br> D) 8
Aleks [24]
What you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.

(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.

32/4 = 8, so your correct choice is D.

A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for p
Mumz [18]

Answer:

3

Step-by-step explanation:

We have given SS_X=10, SS_Y=40 and SP =30

We have to find the slope for regression on Y from X

The slope on Y from X is given by b_{yx}=\frac{SP}{SS_X}

As we have given the value of SP =30 and value of SS_X=10

So slope for regression will be b_{yx}=\frac{30}{10}=3
