The class average would be all the test scores added up and divided by the number of scores.

5+5+1+1+1+1+1+0+0+0+0= 15

15/11=1.37

The class average is 1.37

2(5) + 0(4) + 0(3) +0(2) + 5(1) + 4(0) = 10 + 0 + 0 + 0 + 5 + 0 = 15
Divide by # of students, which is 11, and you get the average as 15/11, or 1.3636.

Zero students means no one scored that score, the only scores that were received were "5" (2 students earned) and "1" (5 students earned) and "0" (4 students earned).

Given that MNOP is a rectangle, find x and y.
IceJOKER [234]
In rectangle, all the angles are 90°. ∠M =∠N = ∠O = ∠P = 90°. Therefore 2X - 10 =  90 and 3Y + 9 = 90. Therefore X = 50 and Y = 27. So option B is correct.

Can someone tell me how to do this ??
suter [353]

Answer:

See step-by-step

Step-by-step explanation:

A prism is named by the shape of its bases.  That makes this an octagonal prism

The shape of the bases are octagons.

The vertices are all the letters

The lateral edges are all the vertical lines connected by the vertices.  RQ, WN, VM, are all examples.

The rectangles making up the sides are called lateral faces.

The altitudes are the same as the lateral edges.  They all represent the height of the prism.

f(2) = 2(-3) + 1

f(2) = (-6) + 1

f(2) = -5
