Answer with Step-by-step explanation:
We are given that a function
We have to find the graph of the given function.
y-intercept:It is that value of y where the graph cut the y- axis.
Let
Substitute x=0
Then, we get
y-intercept of the graph=-15
x- intercept: It is that value of x where the graph cut the x- axis.
Substitute y=0
Substitute x=-1
Therefore,x=-1 is a solution of given equation.
Hence, the x-intercept are
-3,-1 and 5
Due to the higher z-score, the correct option regarding the highest relative score is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
<h3>What is the z-score formula?</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
The z-score measures how many standard deviations the measure is above or below the mean, hence the higher the z-score, the higher the score X is relative to other scores.
The respective z-scores for this problem are given by:
- (39 - 31)/6.1 = 1.31.
- (1136 - 1080)/67.8 = 0.83.
- (4730 - 3960)/555.5 = 1.39.
Hence the correct option is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
