Answer:
8 and 3
Step-by-step explanation:
8 x 3 is 24
6 x 4 is 24
or in other words divide 7.5 by 9 to get your answer which is .83333.. which is the same as 5/6 of a page per minute.
Check
5/6 + 5/6 + 5/6 + 5/6 + 5/6 +5/6 +5/6 +5/6 +5/6 + 45/6 or 7 3/6 = 7 1/2
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
Well you would just multiply 374 by 15 and that would be your answer
