Answers

Answer:

Step-by-step explanation:

mean is 4, 5,6,3

Find the mean of the list:

(4, 5, 6, 3)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 4 + 5 + 6 + 3:

(4 + 5 + 6 + 3)/(number of elements)

Counting, we see that the list has 4 elements:

(4 + 5 + 6 + 3)/4

4 + 5 + 6 + 3 = 18:

18/4

1. What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.? (1 point)
P = 35 in., A = 300 in.2
P = 70 in., A = 300 in.2
P = 300 in., A = 70 in.2
P = 35 in., A = 200 in.2

Answers

Answer:

It's the 2nd one

Step-by-step explanation:

So to find the perimeter you add all the sides together. So if 2 of the sides are 20 and 15, that means the other ones are 20 and 15.

Once you add those all together you get 70.

To find the area you multiply the two different sides, so that would be 20 and 15.

20 times 15 is 300.
