The nine cat in a pet store were weighed. their weights (in pounds) are given 7,7,7,2,4,4,7,1,9

To easily find the mode, put the numbers in order from least to greatest

Which is, 1,2,4,4,7,7,7,7,9

 Count how many times each number occurs. The number that occurs the most is the mode!

7 occurs the most! So the mode is 7.

Find the largest and smallest values in the set

They are 1 and 9.

Subtract the smallest value from the largest value to find the range

1 - 9 =  8

The range is 8.

The mode is the number in a set of numbers that you see the most...
The range is the difference between the highest and lowest number
So for the numbers 7, 7, 7, 2, 4, 4, 7, 1, 9, 
The mode would be 7 as it's the most common number
The range would be 8 because if you subtract the lowest number from the highest (9-1) you would get 8

Hope this helps! :)

Answer: choice c and choice d

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

The reporter forgot to multiply the decimal by 100, making it 25%
