Answer:
i think its D but im not entirely sure, im sincerly sry if im wrong
Step-by-step explanation:
The 99 percent confidence interval for the true mean length of the bolt is CI = (2.8712, 3.1288)
<h3>How to find the confidence interval?</h3>
Confidence Interval is used to tell us the degree of certainty or uncertainty that is existent in a sampling method.
The general formula for confidence interval is;
CI = x' ± z(s/√n)
where;
x' is sample mean
z is z-score at confidence level
s is sample standard deviation
n is sample size
We are given;
sample size; n = 36
Sample mean; x' = 3 inches
standard deviation; s = 0.3 inches
confidence level = 99%
z at 99% CL = 2.576
Thus;
CI = 3 ± 2.576(0.3/√36)
CI = 3 ± 0.1288
CI = (2.8712, 3.1288)

Answer:
1) 0.75
2) y =
x - 3
3) (4, 0); (0, -3)
Step-by-step explanation:
Convert to slope-intercept form (y = mx + b) by solving:
y =
x - 3
m is the slope, so
or you can write as 0.75.
To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.
