Answer:
p//q
Step-by-step explanation:
p and q are parallel since the exterior angles are congruent
Answer:
115
Step-by-step explanation:
Given :
Mean of intelligence score = 100
Standard deviation of intelligence score = 15
Since both are perfectly correlated,
The Zscore ON SAT = +1.0
Using the standard normal interpretation, Xcore on SAT of +1.0 means 1 standard deviation to the right
This means :
Mean + 1 standard deviation
100 + 1*15
= 115
We could use the Zscore formula directly too:
Zscore = (x - mean) / standard deviation
Zscore = +1 ; x = score
Hence, we have
1 = (x - 100) / 15
1 * 15 = x - 100
15 = x- 100
x = 15 + 100
x = 115
Alright, so first we'll have to get y on the other side
So
2x+y=-9
-y -y
+9 +9
2x+9=-y
Then divide is all by -1 so y is positive
-2x-9=y
Answer:
C≈62.83
Step-by-step explanation:
Use the formula C=πd
Plug in 20 for d and simplify
You then get 62.8318530718 in a calculator
So, you round it to 62.83
