Answer:

65 square units

Step-by-step explanation:

The area of a triangle is: height times base divided by two.

So the area of one of the triangles is 10 square units.

multiply this times 4 to get the total area of the triangles

then add the area of the square which is 5 times 5

25 plus 40 = 65 square units

Alana rode her bicycle 10 miles on Tuesday and 20 miles on Wednesday. What is the mean absolute deviation of this data?
stiks02 [169]

Answer:

5

Step-by-step explanation:

Given that :

Miles ridden in Tuesday = 10

Miles ridden on Wednesday = 20

Sample size, n = 2

Mean :

(10 + 20) / 2

= 30 /2

= 15

Mean absolute deviation :

(|10 - 15| + |20 - 15|) / 2

(5 + 5) / 2

10 / 2

= 5
