Answer:

Step-by-step explanation:

Mary bought 1 fish, Ari bought 20 fish, Rodney bought 4 fish, Carissa bought 3 fish, Jacob bought 4 fish, Jack bought 1 fish, Jaleesa bought 2 fish, Andrea bought 5 fish, Geoff bought 1 fish, Becky bought 4 fish, Molly bought 1 fish, David bought 2 fish, Gina bought 7 fish, James bought 1 fish, Anessa bought 2 fish, Ted bought 1 fish, Sean bought 2 fish, Kerri bought 11 fish, Sammy bought 3 fish, Jameson bought 2 fish, Theresa bought 2 fish, Luz bought 2 fish, Tracy bought 4 fish, Jackson bought 5 fish, and Celia bought 7 fish.

Rewrite the numbers

1,20,4,3,4,1,2,5,1,4,1,2,7,1,2,1,2,11,3,2,2,2,4,5,7

1.

a: I can't draw a line plot, but I can tell you some tips.

Set the x as the different numbers that appear in the set

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

d: The outlier is 20 bought fish

2.

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

. Denise has multiplied (2r – 3)(2r + 3) to get 4r2 – 9. After looking at her work, Hyder says her solution must be incorrect be
makvit [3.9K]

Answer:

The answer is 4r² – 9

Denise answer is correct.

Step-by-step explanation:

One of the methods of solving the given equation [(2r – 3)(2r + 3)] is the FOIL method

Using the FOIL method (Used for multiplying binomials)

F stands for first

O stands for outer

I stands for inner

L stands for last

In this method, it means we will first multiply the first terms followed by multiplying the outer term, then multiplying the inner terms and finally, the last terms.

So, for the equation  (2r – 3)(2r + 3)

First : (2r)(2r) = 4r²

Outer : (2r)(+3) = 6r

Inner : (–3)(2r) =  – 6r

Last :  (–3)(+3) =  – 9

Adding the results we get

4r² + 6r – 6r – 9 (+6r and – 6r cancels out)

= 4r² – 9

∴ (2r – 3)(2r + 3) = 4r² – 9

Hence, Denise answer is correct
