8
Step-by-step explanation:
2,3,5,11,13,14
Mean= 8
Standard deviation= 4.830
Reduce the common factors of the top and bottom of the fraction. You should be left with (-2d^2 ef^4)/3
Answer:
Angle x=19°
Angle Y=53°
I might be wrong though.
Step-by-step explanation:
Since a right angle is 90° and a straight line is 180°,the other side(71+x)=90.Therefore,90-71=19,which is angle x.
There is another straight line,since angle x is 19°.All you have to do is subtract 71+37+19 from 180 to get Angle Y.The answer is 53°.
Angle X=90-71=19
Angle Y=180-37-71-19=53.
The answer for that is 23/16
