I believe you combine the first and last terms first because they have the same denominator
118.56. 31.2 x 3.8 = 118.56
a(n) = 6n - 7
a(12) = 6(12) - 7
a(12) = 72 - 7
a(12) = 65
The answer is B.
Using the normal distribution, it is found that 0.0329 = 3.29% of the population are considered to be potential leaders.
In a <em>normal distribution</em> with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 550, hence
.
- The standard deviation is of 125, hence
.
The proportion of the population considered to be potential leaders is <u>1 subtracted by the p-value of Z when X = 780</u>, hence:



has a p-value of 0.9671.
1 - 0.9671 = 0.0329
0.0329 = 3.29% of the population are considered to be potential leaders.

The area of a triangle is 1/2 bh. First, you add 24+37+3. Your answer is 64. Now you are gonna find 1/2 of 64, which gives you your answer of 32.
