Answer:
The proportion of individuals score at most 74 points on this test is 70%.
Step-by-step explanation:
The complete question is:
Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.
Solution:
Let <em>X</em> represent the scores on a reading ability test.
It is provided that .
Compute the probability that an individuals score is at most 74 points on this test as follows:
Thus, the proportion of individuals score at most 74 points on this test is 70%.
Given:
From the function above, there was a horizonal stretch.
using the transformation rule:
Therefore, we can say that there is a horizontal shift of the graph to the right.
ANSWER:
B. The graph of the function g(s) is a horizontal shift of the graph of the function to the right.
Given:
The inequality is:
To find:
The values for x.
Solution:
We have,
Using distributive property, we get
On further simplification, we get
Divide both sides by 7.
Therefore, the required solution is .
Note: All options are incorrect.
