Answer: 20% = 0.2

Step-by-step explanation:

-Add all the ball for a total frequency (15 balls)

-Find the frequency of each ball

5/15= 0.33

3/15= 0.2

6/15= 0.4

1/15= 0.67

-multiply by 100 to get a percentage.

Answer:

1/5 or 1;5, or .2, or 20%

Step-by-step explanation:

First, lets add 5, 3,6 and 1 together.

5+3+6+1=15

3 of these are tennis balls. This, as a ratio, would be 3/15. Simpified, tis would be 1/5.

The height of a parallelogram is one-third its base. If the area of the parallelogram is 363 square inches, find its base and he
kipiarov [429]

Answer:

Height = 11 inches

Base = 33 inches

Step-by-step explanation:

In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.

From the question, we are told that height is 1/3 of base. This means that base is 3 times the height

So if we represent the height with variable h, then the base is 3h

Mathematically the area of a parallelogram can be calculated by the formula

A = bh

Thus ,

363 = h * 3h

3h^2 = 363

divide through by 3

h^2 = 121

h = √121

h = 11 inches

since b = 3h , then b = 3 * 11 = 33 inches

Select the correct answer.<br> Which graph shows a function and its inverse?
labwork [276]

Answer:

See below

Step-by-step explanation:

If a function is bijective and 1-to-1, then it will have an inverse function. Consequentially, they will be symmetrical about the line y=x, which is a diagonal line passing through the origin at a 45 degree angle.

None of the graphs look correct though, but it also seems that some options are cut out, so make sure to choose the correct graph given the characteristics I've previously described.
