What is the mean of the data set? {32, 33, 34, 34, 36, 38, 38, 38, 40, 42}

Add all the numbers:

32 + 33 34 + 34 + 36 + 38 + 38 + 38 + 40 + 42 = 365

There are 10 numbers.

Divide:
Total by how many numbers there are

Total = 365
Numbers = 10

365 / 10 = 36.5

The mean is 36.5

Hope this helped☺☺

36.5 is the mean of the set of data. The mean Is the average of the set. To find the average you:

1) Add up all of the numbers in your set. (365)
2) Then, divide the sum by the quantity of numbers. (365/10=36.5)

Triangle XYZ has vertices at X(–2, –1), Y(–3, –6), and Z(–7, –5). If triangle XYZ is rotated 90° clockwise, what will be the coo

Delvig [45]

Answer:1. Is right 3 down 5, because to get from x(0,0) to x'(3,-5), you need I shift to the right 3 and downwards 5.

2. Counterclockwise 180 degrees. This is because 180 degrees is half of a full rotation (360 degrees), meaning the point would be the same no matter which way you rotated 180 degrees.

3. Clockwise 90 degrees. Going counter clock wise 270 degrees is like going around 3/4 of a circle (because 270/360 is 3/4). Just as well, going clock wise 90 degrees is like going 1/4 of the circle, but in the opposite direction. This means they will both land at the same point.

Hope this Helps!

In triangle ABC, medians AD, BF, and CE intersect at G. What is the length of GE is CH=12?

sashaice [31]

You do not have any point labeled "H" in your diagram.

What I can tell you is that point "G" (where all 3 medians meet) is called a centroid.

Along each median:
the distance from EACH vertex to the centroid (point G) is TWICE the distance from the centroid to the side.
CG = 2*GE AG = 2*GD BG = 2*GF

Can someone please help me with b, d, and 9-13? I already drew a number line, thanks in advance! :)

inessss [21]

B)
$\frac{3}{13} = s$
d)
$\frac{5}{4} = s$
9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,

10)
${2}^{2} = 4$
${3}^{2} = 9$
so {5, 6, 7, 8} is the answer

11) for some reason it won't let me insert a picture but put place
$\sqrt{4}$
above 2, and then place
$\sqrt{9}$
above 3, and then place
$\sqrt{7}$
in between 2 and 3, but place it a little closer to three since
$\sqrt{7} = 2.65$
12) place
$\sqrt{5}$
between 2 and three, but closer to two since
$\sqrt{5} = 2.24$
and also
$\sqrt{5} < \sqrt{7}$
and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.

I hope this helped and if not, message me and ill try to explain!
