Your answer: 4,744,473,263,806,742
The answer is C. 4
7 - 5 x 3 + 4 x 3
= 7 - 15 + 12
= -8 + 12
= 4
Answer:
n=12
Step-by-step explanation:
I'm assuming you want to solve for <em>n</em>
First, you must use distributive property:
-30=-2n-6
Then, add 6 to both sides
-24=-2n
Finally, you must divide by -2
12=n
Answer:
Note that we need calculate the scores between the mean (
) and the mean plus 3 times the standard deviation. It is 3 times since the distance between the values given (513 and 759) divided by the standard deviation is 3 (
)
So the rule say that 99.7% of data is between
and
, as it is a normal distribution half of 99.7% is between
and
. Hence 49.85% of people score between 513 and 759.
