Alicia plots a point at (0, 5) and (0, -2). What is the distance between the points?

In (5,0), five represents how many times he will move over in the X axis. Since it’s zero, you do not move at all. However you will move five spot up, because the five is on the Y axis. Then, he will do the same thing with your second pair of coordinates. You do not move on the X axis, but you will move two spots down on the Y axis. Then, trace your pencil between the two dots. You will notice that it passes seven intersections, so your answer will be seven units.

Factor the expression completely.

sashaice [31]

It would be A because -2.25*3=-6.75 and -2.25*x=-2.25x giving us are end answer of, -6.75+2.25x

Enjoy!=)

(P.s. I am not 100% sure if this is completely factored but it should be)

he accompanying data provide the heights of some singers in a chorus, collected so that the singers could be positioned on stag

stellarik [79]

The image of the histogram distribution is missing, so i have attached it.

Answer:

Option C: The distribution is unimodal. Its mode is near 60 inches

Step-by-step explanation:

Mode simply means the most occurring value in a set of data.

Now, for histogram, the mode is the highest peak represented in the bars.

Now, from the image attached, it is seen that there is a clear highest peak. Thus, the histogram has only one peak and it can be described as unimodal.

We are not given the mode height from the histogram but we can see that it is between 60 and 68 inches. And if carefully observed it will have a value closer to 60.

Thus,option C is correct.

Surface area of this right prism

Sphinxa [80]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textsf{Let's calculate the surface area of given right prism}$

$\textbf{Area of Triangles :}$

$\sf{\dfrac{1}{2}\cdot 16\cdot 12}$

$\sf{8×12}$

$\sf96 \: \: cm {}^{2}$

$\textsf{Since there are two triangles, }$

$\textsf{Area of Triangles = 96 × 2 = 192 cm²}$

$\textbf{Now, calculate the Areas of rectangles :}$

$\textsf{Area - 1 = 12 × 10 = 120 cm²}$

$\textsf{Area - 2 = 16 × 10 = 160 cm²}$

$\textsf{Area - 3 = 20 × 10 = 200 cm²}$

$\textsf{Now add them all :}$

$\textsf{120 + 160 + 200 + 192}$

$\textsf{672 cm²}$
