To find the mean, add up at the numbers and divide by the number of numbers in the set (6)

9 + 4 + 7 + 3 + 10 + 9 = 
9 + 11 + 12 + 10
20 + 22
42 

42 / 6 = 7

the mean is 7.

Find the mean of the data set: 9 4 7 3 10 9

Mean means average. To find the mean of the date set, you need to add up all the given numbers, then, divide the number by the following amount of numbers.

9+4+7+3+10+9 = 42

42/6 = 7

The mean of the data set is 7.

Hope I helped (:

Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.

1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81

2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...

Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.

An unopened cereal box contains 15/28 cubic foot of cereal. If the box is full, and the length and height of the box are5/7 and
kenny6666 [7]
Volume is height times length times width

V = 15/28 ft^3
h = 11/2 ft
l = 5/7
w = ?

So the unsolved equation is:
V = h × l × w

Separate the w by diving both sides by h and l:
w =  \frac{v}{hl}
Then plug in the numbers:
w =  \frac{( \frac{15}{28}) }{( \frac{11}{2} ) \times ( \frac{5}{7}) }
Which, with the fractions flipped, equals:
w = ( \frac{15}{28} ) \times ( \frac{2}{11} ) \times ( \frac{7}{5} ) \\  w =  \frac{210}{1540}
w =  \frac{3 \times 7 \times 10}{10 \times 2 \times 7 \times 11}  \\ w =  \frac{3}{2 \times 11}  \\ w =  \frac{3}{22}
The width of the box is 3/22 ft
