A.) 200cm
B.) 206cm
A explanation.) To find the mean, you add all the heights and divide by 5 (how many numbers there are), this gives you 1000 divided by 5, which equals exactly 200cm.
B explanation.) I tried the equation with numbers higher than 202, going up one each time, and 206 was the one that equaled exactly 201.
Step-by-step explanation:
angle MNP = angle QPL (corresponding angles, //lines) (A)
angle QLP is common angle (A)
By AA, the 2 triangles are similar.

Answer:
D 80 and 90
Step-by-step explanation:
using reverse problem solving
square root x = 9 then
9 squared =81
81 between 80 and 90
The slope of a line is calculated by dividing the one y portion of the line by one x portion of the line. In this problem we have two points which can indicate us one portion of the y axis and one portion of the x axis. If we have two points of one line, then we can calculate its slope:
Point one (x1, y1)
Point two (x2, y2)
then the slope can be calculated as:
m = (y2 - y1)/(x2 - x1)
So lets use our data:
Point one (2, 10)
Point two (5, 8)
then the slope can be calculated as:
m = (8 - 10)/(5 - 2<span>)
</span>m = -2/3
therefore the slope is negative and is -2/3
