Check the picture below.
so, let's notice, is really just a 2x20 rectangle with a quarter of a semicircle with a radius of 11.

Answer:
f(x)= (-4)/(5-X)
Step-by-step explanation:
Answer:
3 times 4 over 5 equals 2.4
Step-by-step explanation:
this Is a semi easy one the answer is 21. here is how you do it.
first change 56% into a decimal which comes out to be .56 now subtract it from 100% but in decimal form which is .1.
.1-.56=.44
now you want to take that .44 and multiply it by 14 which comes out to be 6.16 but you cant have .16th of a person so lets just say its 7 people.
now add 7 to the 14 clowns and you get 21.
plz rate my answer as brainliest also feel free to add me as a friend as I am very good at this subject.
The interval would be from 87.8 to 124.8.
68% of the data fall within one standard deviation of the mean, so we calculate
106.3 +/- 18.5:
106.3 - 18.5 = 87.8
106.3 + 18.5 = 124.8
