-0.2 is not a possible value of x because lengths cannot be negative.
We're given

which immediately tells us that

In other words, swapping the limits of the integral negates its value.
Also,

The integral we want to compute is

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is

The square root of 147 when rounded to the nearest tenth is about 12.1
Answer:
A
Step-by-step explanation:
Lets dissect the dot plot for information:
1 point = 1 time
2 points = 2 times
3 points = 3 times
7 points = 1 time
8 points = 3 times
9 points = 1 time
10 points = 1 time
Total number of times he gets extra credit points is:
1 + 2 + 3 + 1 + 3 + 1 + 1 = 12 times
Out of which "3" was 3 times
and "7" was 1 times
That would make it
3 + 1 = 4 times
So, out of 12 times in total he gets extra credit points, 4 times is "3" or "7". In percentage, that will be:
4/12 = 0.3333
Multiplying 0.3333 * 100 = <u>33.33%</u>
