Answer: 67.5
Step-by-step explanation:
Given: The mass of drug = 450 mg
The mass percent error = 15%
Which can be written as 0.15.
We use the formula :-
Similarly,
Hence, the mass error would be 67.5 mg.
Answer:
The rate of change is zero
Step-by-step explanation:
When drawn on graph paper, the 2 points are horizontal (they have the same y-value). When plugging in values in the slope formula, (y2-y1)/(x2-x1) you will get 0/4, which is still zero.
The answer would be C.
If you do -5.5 + 2.5 over 6.1 - 3.1 it would be -3 over 3 which is equal to -1.
You could also do -2.5 + 5.5 over 3.1 - 6.1. It would be 3 over -3 which is also equal to -1.
Divide 5 by 1.25. That equals 4. Multiply 4 by 20 and that equals 80. So its 80 miles between Longwood and Milltown.
Answer: The point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
Step-by-step explanation:
The confidence interval for population mean is given by :-
, here is the point estimate of the population mean and E is the margin of error .
As per given , we have
Lower bound of CI = (1)
Upper bound of CI = (2)
Add (1) and (2) , we get
Subtract (1) from (2) , we get
Hence, the point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
