Answer:
Step 1: Calculate the mean of the data—this is \muμmu in the formula.
Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations.
Step 3: Square each deviation to make it positive.
Step 4: Add the squared deviations together.
Step 5: Divide the sum by the number of data points in the population. The result is called the variance.
Step 6: Take the square root of the variance to get the standard deviation

Answer:
7560 in^3
Step-by-step explanation:
Hello! The first thing that we must take into account to solve this problem is that the volume of any solid is equal to the transverse area by the height, in this case we must find the area of the trapezoid and then multiply it by the height
V=AL
V= Volume
A=area
L=height=9in
finding area of trapezoid

To know what each variable corresponds to, please see the attached file

finally multiply the area by the height of the box(9in)
V=AL
V=(840in^2)(9in)=7560in^3
the volume of the flower box is 7560 in^3
Answer:
D. they played 30 games in total
Step-by-step explanation:
By a process of elimination we can determine that D is the answer.
30 is the only answer that gives 12 when multiplied by 0.40
in other words, 12 is 40% of 30
Answer: 2880
Explanation: First, multiply 40 and 4 together to find the value of h. This should get you to 160. Then plug in 160 into h in the equation e=18h. This multiplies 18 and 160 together. You will then get an answer of 2880.
