To solve this problem you must apply the proccedure shown below:
1. You have that the baby pool holds 
and the medium pool measures three times the height and width of the baby pool and both have the shape of a cylinder. Then, you can use the formula for calculate the volume of a cylinder, which is:
Where 
is the radius (the half of the width), and 
is the height.
2. As the height and the width of the medium pool measure three times the height and width of the baby pool, you must multiply the radius and the heigh by 
, therefore, the volume of the medium pool (
) is :
The answer is: B. 
We are given a table of frequencies, so in order to find probability associated with it, we need to start by adding all the numbers in the frequency, since that would give us the totals:
We add :
7.7 + 8.2 + 24.1 + 25.6 + 51.5 + 29. 4 = 146.5
Now, notice that they ask you to find the probability associated with a voter chosen at random to be in a group DIFFERENT from the range 21 to 24, That means the complementary of this range, which is therefore
146.5 - 8.2 = 138.3 (since 8.2 is the frequency for the 21 - 24 years/age range.
Then the probability is the quotient:
138.3 / 146.5 = 0.9440273 which in percent terms is 94.4 %
If you teacher wants the probaility in decimal (math) form, use 0.944.
If he/she wants it in percent form, use 94.403% (using
Answer:
x - 17.95 = 71.80, $89.75
Step-by-step explanation:
Let the original price of the headphones be x
Amount of coupon = $17.95
You pay the final amount for the headphones after using the coupon = $71.80
So to find the original price of the headphones, the equation will be
x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75
Given the following group of numbers, 8, 2, 9,4, 2, 7, 8, 0, 4, 1, which of the following

Answer:
III. The mode is 2
Step-by-step explanation:
Mean: (8+2+9+4+2+7+8+0+4+1)/10 = 45/10 = 4.5
Median: (2+7)/2 = 9/2 = 4.5
Mode: There is no mode since 2 and 8 both appear twice (in other words, since they have the same frequency, it's bimodal)
The closest possible choice is III. The mode is 2, but keep in mind that since the data set is bimodal, there is no single mode.
