Step-by-step explanation:

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|.

The mystery number has five digits,the digit in the tenth place is double the digit in the tens place,the mystery number rounds

hjlf

Answer:

See explanation

Step-by-step explanation:

If the mystery number rounds to 700, then it has 3 digits before decimal points and two digits after decimal point.

Hence, the mystery number is

$a b c . d e$

The digit in the tenth place is double the digit in the tens place, so

$d=2b$

If b = 1, then d = 2

If b = 2, then d = 4

If b = 3, then d = 6

If b = 4, then d = 8

The difference between the digit in the hundreds place and the ones place is 3, so

$a-c=3$

The first digit can be only 7, because b < 5 and the number rounds to 700. So

If a = 7, then c = 4

All possible answers:

714.2e

724.4e

734.6e

744.8e,

where e is an arbitrary digit from 0 to 9.

There are 40 possible numbers which match the situation.

The stadium vending company finds that sales of hot dogs average 35,000 hot dogs per game when the hot dogs sell for $2.50 each.

erma4kov [3.2K]

Answer:

A function R x that models the total revenue per game is as follows:

Rx = 87,5000 + 3,750x – 500x^2.

Step-by-step explanation:

Based on the information in the question, we have:

Rx = Total revenue per game

x = Number of $0.25 increases in the price of a hot dog

Average sales of hot dogs = 35,000

Effect of each 25 cent increase in the price on average sales = 35,000 - 2000x

Effect of each 25 cent increase in the price on selling price = 2.5 + 0.25x

Therefore, we have:

Rx = (35,000 - 2000x)(2.5 + 0.25x)

This can be solved further by opening the brackets as follows:

Rx = 87,5000 + 8,750x - 5,000x - 500x^2

Rx = 87,5000 + 3,750x – 500x^2

Therefore, a function R x that models the total revenue per game is Rx = 87,5000 + 3,750x – 500x^2.

The Better Baby Buggy Co. has just come out with a new model, the Turbo. The market research department predicts that the demand

andreyandreev [35.5K]

In this question, q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:

revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p

The maximum revenue should be in the peak of the graph. The calculation would be:
-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
-8p + 616=0
8p= 616
p=77

Put p=77 in the revenue equation would result
revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716

A school choir needs to make T Shirts for its 75 members and has set aside some money in their budget to pay for them. The membe

aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

If a school choir needs to make T Shirts for its 75 members and the printing company charges $3 per shirt, the total amount paid for shirts without coloured printing will be $3 * 75 = 3(75) ... 1

If the printing company charges $50 fee for each color to be printed on shirts, then the total number of colours on the short will cost $30C.... 2

where C is the total amount of colours on all the shirts.

The equation that will represents the relationship between the number of T-shirts orders, the number of colors on shirts and the total cost of the order will be gotten by taking the sum of equation 1 and 2.

The equation needed will be 3(75) + 30C where C is the total amount of colours on all the shirts ordered.
