it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
I believe the answer is 65%. i'm not sure
Answer:
The mean increases by 3.
Step-by-step explanation:
<u>What's an outlier?</u>
- An outlier is a data point that's very different from the other data points. In this example, the outlier is 50, as the other data points are around the number 80.
<u>What's the mean of a data set?</u>
- The mean is the average of a data set. It's found by adding up all the numbers in the set and then dividing by the number of data points there is.
<u>How do we solve this problem?</u>
First, we find the mean of the data set with the outlier, 50.
Next, we find the mean of the set without the outlier.
Lastly, we subtract 77 from 80 to find the difference.
Therefore, the answer is The mean increases by 3.
Answer:
A.
Step-by-step explanation:
In the figure attached, the oblique prism is shown.
The volume of the prism is:
V = b*h
where h is the height and b is the area of the base
Given that the base is an isosceles right triangle, its area is:
b = 1/2*x²
The height of the prism is (x + 2). Then, the volume is:
V = 1/2*x²*(x + 2)
V = 1/2*x³ + x²
