Set of your problem as followed.<span>24.5=<span><span>−<span>2.5c</span></span>−<span>4c
</span></span></span>Then you simplify both side of your equation<span><span><span>
</span></span></span>24.5=−6.5c
Flip your equation now
−6.5c=24.5
Divide both sides of the equation by "-6.5"
−6.5c−6.5=24.5−6.5 (imagine a line going through the equal sign)
<span><span><span>
and your answer comes to</span></span></span><span>c=<span>−<span>3.769231

To simplify even further, you'll round.
Since 9 is bigger than 5 then you'll round up to the nearest number. Which is 7. So your answer comes to
6=-3.77
Hope this helps. :)</span></span></span>

The number of newly reported crime cases in a county in New York State is shown in
JulsSmile [24]

Answer:

The linear regression equation that represents  the set of data is:

y=1083.48+23.73x

The predicted number of new cases for 2013 is 1368.

Step-by-step explanation:

The general form of a linear regression is:

y=a+bx

Here,

<em>y</em> = dependent variable

<em>x</em> = independent variable

<em>a</em> = intercept

<em>b</em> = slope

Compute the values of <em>a</em> and <em>b</em> as follows:

\begin{aligned}        a &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} =             \frac{ 6857 \cdot 55 - 15 \cdot 17558}{ 6 \cdot 55 - 15^2} \approx 1083.476 \\ \\b &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2}        = \frac{ 6 \cdot 17558 - 15 \cdot 6857 }{ 6 \cdot 55 - \left( 15 \right)^2} \approx 23.743\end{aligned}

The linear regression equation that represents  the set of data is:

y=1083.48+23.73x

Compute the predicted value of the number of new cases for 2013 (i.e. <em>x</em> = 12) as follows:

y=1083.48+23.73x

  =1083.48+(23.73\times12)\\\\=1083.48+284.76\\\\=1368.24\\\\\approx 1368

Thus, the predicted number of new cases for 2013 is 1368.

You are building a skateboard ramp from a piece of wood that is 3.1 meters long. You want the ramp to make and angle of 25 with
andrew11 [14]

Answer:

30 degrees. 

Step-by-step explanation:

The ladder that extends from the floor to the storeroom makes a right triangle.  The ramp is the hypotenuse measuring 10 m and the elevation of the storeroom is the opposite side. The angle of elevation is the arcsin of the quotient of the 5/10. Thus, the answer is 30 degrees.

I need help with this question asap!
Tpy6a [65]

Answer:

x=15

Step-by-step explanation:

This is an equilateral triangle.  That means all sides are equal and all angles are equal

An equilateral triangle has angle measurements of 60 degrees

60 =4x

Divide each side by 4

60/4 = 4x/4

15 =x
