Answer: the line would start at the 4 and for every half hour you go up by 2 on the Y and for every hour you go up by 4 on the Y

So by hour 3 you should be at 16

Which expression can be simplified to find the slope of the trend line in the scatterplot?
Nutka1998 [239]

Answer:  \frac{35-21}{8-4}

Step-by-step explanation:

The slope of a line equals to the difference between points' y-coordinates divided by the difference between their x-coordinates.

That is, if (x_1,y_1) and (x_2,y_2) are the point of a line,

Then the slope of the line is,

m=\frac{y_2-y_1}{x_2-x_1}

By the given diagram,

x_1=4, y_1=21, x_2=8 and y_2=35

Thus, the slope of the given line

= \frac{35-21}{8-4}

⇒ Fourth option is correct.

A right isosceles triangle has an area of 65cm^2. What's the length of each leg to the nearest tenth of a cm.
Andreas93 [3]

Well, we know that the legs of this triangle are equal, and we know
that the area of any triangle is  (1/2)(base)(height) .

Since this is a right triangle, we can set it down on one leg, and then
the other leg will be the height.  Then ...

    Area = (1/2) (base) (height)

             = (1/2) (leg) (leg)

    65 cm²  =  (1/2) (leg)²

Multiply each side by  2 :  130 cm²  =  (leg)²

Take the square root of each side:      leg = √130 cm²  =  11.402 cm

                                        rounded to the nearest tenth:    11.4 cm
