Answer:
C) 27
Step-by-step explanation:
180-(90+63)
180-153= 27
The angle of QVR seems to be a 90 degree angle which is where I got the 90 from then I added it to the 63 and subtracted 180 since QVT is a straight angle the degree would be 180. Therefore, you add 90 and 63 then subtract 180 to get 27 degrees.
Ben needs to bowl at least 151 to have an average of 170.
Answer:
Undefined.

Answer:
Simplified to -281250
Step-by-step explanation:
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
