Answer:

yes i think the questions are statistical

Step-by-step explanation:

this is because a statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

The line segment joining A(6, 3) to B(–1, –4) is doubled in length by having half its length added to each end. Find the coordin

mr Goodwill [35]

Answer:

(9.5, 6.5) and (-4.5, -7.5)

Step-by-step explanation:

Let the extended points be A' and B' and add the point M as midpoint of AB

Coordinates of M are:

((6 - 1)/2, (3-4)/2) = (2.5, -0.5)

Now point A is midpoint of A'M and point B is midpoint of MB'

Finding the coordinates using midpoint formula:

A' = ((2*6 - 2.5),(2*3 - (-0.5)) = (9.5, 6.5)
B' = ((2*(-1) - 2.5), (2*(-4) - (-0.5)) = (-4.5, -7.5)

X+19=13 Find the value of x.

Oliga [24]

To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-

x + 19 = 13
x = ?
13 - 19 = x
13 - 19 = -6
x = - 6

CHECK OUR WORK:-

x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!

So, x = -6

Hope I helped ya!! xD
