If you have a ruler I can how you a faster why you do this
Answer:
В (50°)
Step-by-step explanation:
m∠XWY=180-95=85°
x=180-(m∠XWY+m∠XYW)=180-(85+45)=50°
The way I answered this question is by putting it in a equal equation. If y and x are directly related then you can solve it by doing the following:
<u>
y</u> <u>15</u> = <u>y</u>
x 18 = 1.6
15* 1.6 = 18*y
<u>24</u> = <u>18y</u>
18 18
1.333333333 = y
1.3 = y
The teacher made progress in standardizing the test scores from the beginning of the year to the end. The MAD tells us this because the difference in the teachers scores from the mean is less at the end. The Mean Absolute Deviation is a measure of variability, and the smaller the number, the less variability there is in the answers. So, in this example there are more scores closer to the average than when they first graded the essays.
