Answer: y=x-2
Step-by-step explanation:
P=(x1,y1), and Q=(x2,y2), we use this to find m because m=y2-y1/x2-x1, by using this you'll see that the slope equals one. So now we have our slope. To solve for b, you need to do b=y1-m*x1, or b=y2-m^x2, it doesn't matter which one you do because the results will be the same, but it is good to check over it. Now that you have your slope and y-intercept, you can put it into the equation y=mx+b, so the answer to the problem is y=x-2.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Answer:
B is True
A, C. D are false
Step-by-step explanation:
Given :
Sample size, n = 120
Mean diameter, m = 10
Standard deviation, s = 0.24
Confidence level, Zcritical ; Z0.05/2 = Z0.025 = 1.96
The confidence interval represents how the true mean value compares to a set of values around the mean computed from a set of sample drawn from the population.
The population here is N = 10000
To obtain
Confidence interval (C. I) :
Mean ± margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.96 * 0.24/sqrt(120)
Confidence interval for the 10,000 ball bearing :
10 ± 1.96 * (0.24) / sqrt(120)
Hence. The confidence interval defined as :
10 ± 1.96 * (0.24) / sqrt(120) is the 95% confidence interval for the mean diameter of the 10,000 bearings in the box.
