1 answer:
Answer:
B.
Step-by-step explanation:
First, using two points (0, -4) and (3, 5), find slope:
Slope, m = 3
Next, determine the y-intercept, b.
The y-intercept is the value of y when x = 0. It is the point where the line intercepts the y-axis.
From the graph given, y-intercept, b, is -4.
Substitute b = -4 and m = 3 into .
The equation would be:

Answer:
Not solvable.
Step-by-step explanation:
The normal way to answer this question would be to use the following formula formula for Standard Normal Distribution
Where
= Minimum Breaking Strength = 10,000 psi
= Mean Breaking Strength = 14,000 psi / 13,000 psi
= Standard Deviation of each manufacturer
We put in the values, get the values of Z and use the Standard Normal Distribution Table to get the values for each manufacturer and compare. The manufacturer with the lower value will produce the lower amount of defective sprints.
Since standard deviation values are not given in this question we cannot solve this equation.
