Step-by-step explanation:

To find the mean you have to add all the numbers together and divide by 8 because there are 8 number so  to find the mean absolute deviation of the data, start by finding the mean of the data set.

Find the sum of the data values, and divide the sum by the number of data values.

Find the absolute value of the difference between each data value and the mean: |data value – mean|.

I need some help with this question:  The MoviePlex theater sold 1,456 tickets.  The theater sold 6 times as many regular price
Amanda [17]
Earl isn't correct: the number 1,456 represents the total number of tickets sold, rather than simply six times the number of tickets sold.

Let x= the discount ticket price

1456 = 6x + x
1456 = 7x
x = 28

28 discount tickets were sold. The total number of tickets sold is equal to both the number of discount tickets sold plus six times that number: 1,456 = 6x+ x. Solve for x.

larisa [96]

Answer:

2340

Step-by-step explanation:

3 3/4=15/4            3 1/4=13/4    turn the mixed fractions into improper fractions

(15/4)(3)(13/4)=36.5625ft³        this is the volume of the shipping box

(1/4)(1/4)(1/4)=1/64ft³                  this is the volume of the fish food box

36.5625/(1/64)                          divide it to find out how much fish boxes can fit

36.5625×64                             flip the fraction and multiply

Ksivusya [100]

Answer:

Ben is incorrect

The solutions are x>-3 and x < 3

Step-by-step explanation:

we have

-x^{2} +9 > 0

Multiply by -1 both sides

x^{2} -9 < 0

Adds 9 both sides

x^{2} < 9

The solutions are

x < 3

and

-x < 3 -----> Multiply by -1 both sides ----> x > -3

therefore

The solution is the interval (-3,3)

In the sport​ competition, France won more gold medals than​ Italy, who won more gold medals than Korea. If the total number of
worty [1.4K]

Answer:

France = 15, Italy = 14, Korea = 13

Step-by-step explanation:

We are trying to find 3 consecutive integers whose sum is 42, then the highest integer will be France's gold medal count since they won the most, the second highest will be Italy, and the lowest integer will be Korea.

let n be the first/smallest integer, since they are consecutive, the next two integers are n+1 and n+2. Summing these, we get n + (n+1) + (n+2) = 42. Solve to get n = 13, n + 1 = 14, and n + 2 = 15
