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.

Answer:
128
Step-by-step explanation:
Split the shape into a triangle and a rectangle.
The base of the triangle is 12 cm.
The height of the triangle is the height of the whole shape minus the height of the rectangle, which is: 14-11=3.
We know that the formula for the area of a triangle is 0.5xbxh
Therefore, the area of the triangle is 0.5x12x3 = 18.
NOW, lets work out the area of the rectangle.
The formula for the area of the rectangle is bxh.
= 11*10
= 110.
Now you add the area of the triangle to the area of the rectangle
18+110.
= 128.
