Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Answer:
The answer is 60.11
Step-by-step explanation:
An adult person receives 425 pieces of mail each year with a standard deviation of 50.
Now, we have the following details :
Mean of sample = 425
sigma = 50
Standard error = 
=
= 60.11
Answer:

First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get

. The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.
