The following graphs have a scale assigned to them: The area of each grid
square is 0.11 (or) sq. units. Which ones are density curves for a
continuous random variable?

  B, D, E

Step-by-step explanation:

The area under the curve must be 1, so must be 9 grid squares. (This eliminates A and C.) The function value must be non-negative, which also eliminates C.

Appropriate curves are B, D, and E.

answer: 20

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
