Find the Mean, Median, Mode, and Range for the following numbers: 18, 10, 9, 15, 18

A. Mean: 14 Median: 15 Mode: 18 Range: 9
B. Mean: 15 Median: 17 Mode: 18 Range: 7
C. Mean: 14 Median: 18 Mode: 15 Range: 8
D. Mean: 16 Median: 15 Mode: 9 Range: 18

Answers

Answer 1
Answer is A.

To find the mean, you add, 9+10+15+18+18 and you get 70. You then divide them by 5 because that’s how many numbers you have and you get 14.

To find median, you rearrange the numbers from largest to smallest, (9,10,15,18,18) and the number in the middle is 15. That is your median.

The mode is 18 because you have more than one of it.

And the range, 18-9=9. You subtract the smallest number from the biggest and you get 9.

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62

Answers

pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)

Answer:

     2(4 w + 3) = 62

          width  =7      length = 21

Step-by-step explanation:

For the perimeter you need :

2 times the width     and    2 times the length (length =3w)

so

2(w+1) + 2 (3w+2) =

2w+2 + 6w+4 =

8w +6

you  can factor this by:

2(4w+3)

                      8w +6= 62

                       8W = 56

                      w= 7      l= 21

                    2(7+1)  + 2 (21+2)

                           16 +  46 = 62
