The answer would be x,2x,3x because x is the first angle, the second angle is two times the amount (2x) and the third angle is the sum of the other two angles (x + 2x = 3x).

Hope this helps.

Answer:

Sample mean for solution 1:  19.27; sample mean for solution 2:  10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32

Given the two points (-1,-4) and (2,5): a. Find the slope between these two points
Dvinal [7]
Easy, using \frac{y1-y2}{x1-x2} to find the intercept:

\frac{-4-5}{-1-2}=

\frac{-9}{-3}=3

This is your slope. m=3

To find y=mx+b form

-4=3(-1)+b

-4=-3+b

-1=b

y=3x-1 in y=mx+b form
