Answer:
5
Step-by-step explanation:
700-35w=450+15w
Subtract 15 from -35
700-50w=450
Subtract 700 from 450
-50w=-250
divide -250 by -50w
answer is 5
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%
