Answer:
True
Step-by-step explanation:
Bisector means to cut into two equal halves. The midpoint is the middle point so it halves the line too.
If a segment is perpendicular to while cutting it in half, then it is called a perpendicular bisector.
Answer:
y=1/3x-11
Step-by-step explanation:
Perpendicular to y=-3x
Get the negative reciprocal to find your new slope
1/3x is our new slope
y=mx+b
Plug coordinates in:
-2=-3(-3)+b
-2=9+b
b=-11
Given that the scale readings of the laboratory scale is normally distributed with an unknown mean and a standard deviation of 0.0002 grams.
Part A:
If the weight is weighted 5 times and the mean weight is 10.0023 grams, the 98% confidence interval for μ, the true mean of the scale readings is given by:
Thus, we are 98% confidence that the true mean of the scale readings is between 10.0021 and 10.0025.
Part B:
To get a margin of error of +/- 0.0001 with a 98% confidence, then
Therefore, the number of <span>measurements that must be averaged to get a margin of error of ±0.0001 with 98% confidence is 22.</span>
