Answer:%28a-b%29%2Fb=c
a-b=bc
a=bc%2Bb
a=b%28c%2B1%29
a%2F%28c%2B1%29=b
b=a%2F%28c%2B1%29
So the answer is b=a%2F%28c%2B1%29

Answer:
a cone with a base circumference of about 126 mm
Step-by-step explanation:
Rotating a triangle about a line results in a cone created by the rotation. This is because the segment at the bottom forms a circle, and the point at the top stays there; the three-dimensional figure with a circular base and a point at the top is a cone.
Since we rotate the segments about a line, this makes the length of the base the radius of the circle. This means the circumference would be
C = 2πr = 2(3.14)(20) = 125.6 ≈ 126 mm
A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.
Given that your class rank in 2018 was 89 out of 360 students, while in 2019 your class rank was 95 out of 450 students, to determine A) in which year did you have the higher percentile ranking, and B) if you had the data on the cumulative GPA of each student at the end of the spring semester in 2018, which measure of average would be the most meaningful - mean, median or mode -, the following calculation should be performed:
- 360 = 100
- 89 = X
- 89 x 100/360 = X
- 24.72 = X
- 450 = 100
- 95 = X
- 95 x 100/450 = X
- 21.11 = X
Therefore, A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

Answer:
Feb. 2 marks Groundhog Day, when traditionally a Pennsylvania groundhog known as Punxsutawney Phil makes an appearance above ground, near the cozy tree stump he calls home. Legend has it that if he sees his shadow, North America is in for six more weeks of winter weather.

Answer:
Less than 100. Z=83
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(101+116+Z)/3
300=217+Z
83=Z
