- 3.47
__________
4. 4 3
I couldn't regroup but of you cross out 0 and put 10, 10-7= 3
and you have to borrow one from 9 and make it 8 and 8-4=4
Answer:
A is incorrect! <u>B. should be the correct answer</u>
Step-by-step explanation
After some research, i found that the correct answer is most likely <u><em>B. a regression line and trend line are equivalent terms</em></u>
<em />
<em>A trendline and a regression can be the same.
</em>
<em>
A regression line is based upon the best fitting curve Y= a + bX Most often it’s a least-squares fit (where the squared distances from the points to the line (along the Y-axis) is minimized).
</em>
<em>
It can be quadratic or logistic or otherwise, but most often it is linear.
</em>
<em>
A trendline is often constructed by smoothing of the results, making it less peaked. (often by using a moving average); but can also come from ARIMA projections or curve fitting techniques (such as regression).</em>

You need to calculate how many times the required difference is of the standard deviation, i.e. the ratio difference / standard deviation.
These are the calculations:
Standard deviation = 0.2 mm
Difference between 25.6mm and the mean = 25.6mm - 25mm = 0.6 mm
Ratio difference / standard deviation = 0.6mm / 0.2 mm = 3.
Then, the answer is that a ball with a diameter of 25.6 mm differs 3 standard deviations from the mean.
Answer:
7.5 years
Step-by-step explanation:
P = $5000,
R = 4.25%,
A = $6593.75,
N =?
SI = A - P = 6593.75 - 5000 =$1593. 75

35 + 0.10m = 25 + 0.15m
35 - 25 = 0.15m - 0.10m
10 = 0.05m
10 / 0.05 = m
200 = m.....the price will be the same at 200 miles...they will both cost : $ 55
