Answer:
The score that separates the lower 5% of the class from the rest of the class is 55.6.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question:

Find the score that separates the lower 5% of the class from the rest of the class.
This score is the 5th percentile, which is X when Z has a pvalue of 0.05. So it is X when Z = -1.645.


The score that separates the lower 5% of the class from the rest of the class is 55.6.
Answer:
Step-by-step explanation:
Line is passing through the point
and has slope (m) = - 9
General equation of line in point slope form is given as:
Therefore
This is the required equation of line in point slope form.
Answer to A:
50%
Explanation for A:
We're looking for how many numbers are odd, so theres 1, 3, 5 ,7, four numbers.
We have a total of 8 numbers.

To make any number a percent we move the point over to the right by two, which makes our final answer 50%
Answer to B:
37.5%
Explanation for B:
If the number is less than four, that means we need to find if it will roll the first three numbers. We, once again, have eight total possibilities

0.375 can be turned into our final answer, 37.5%
