Hello!
To find the circumference, you multiply the diameter by pi. We will do so below.
2.5≈7.85
a. 7.85 feet
___________________________________________________
To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.
5,280/7.85≈672.61
b) 672.61
I hope this helps!
50, 66, 73, 74, 75, 75, 76, 76, 81, 81
Remember, the range is when you subtract the lowest number from the highest number :)
Range : 81 - 50 = 31
Remember, the median is the middle number of an ordered data set from least to greatest.
Median : 75
Remember, the mode is the number that is on there the most.
Mode : 75, 76, 81 are all considered to be modes. However, if that is not one of the answer options, then your answer would be : There are not modes.
~Hope I helped!~
Answer:
57⁰
Step-by-step explanation:
This is because angle w and the angle with a measurement of 57⁰ are verticle angles, which makes them congruent.
Answer:
Properties of a normal distribution
The mean, mode and median are all equal.
The curve is symmetric at the center (i.e. around the mean, μ).
Exactly half of the values are to the left of center and exactly half the values are to the right.
The total area under the curve is 1.

Answer:
width = 20
length = 28
Step-by-step explanation:
perimeter=96
width=x
length=x+8
(length*2) + (width*2) = perimeter
2(x+8) + 2(x) = 96
2x+16+2x=96
4x+16=96
4x=80
x=20
width = 20
length = 28
