The minimum grade a student needs to have to qualify for the bonus points is of 85.16.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 72 and a standard deviation of 8.
This means that
What is the minimum grade a student needs to have to qualify for the bonus points?
The 100 - 5 = 95th percentile, which is X when Z has a p-value of 0.95, so X when Z = 1.645.
The minimum grade a student needs to have to qualify for the bonus points is of 85.16.
Answer:
The required graph is shown below.
Step-by-step explanation:
The given equation is
To draw the graph we need at least two points which satisfy the given equation.
At x=0,
At y=0,
So, (0,-4) and (3,0) are two solutions of the given equation. Plot these two points on the coordinate plane and connect them by a straight line.
The required graph is shown below.
