Answer: 432 units²

Step-by-step explanation:

The figure is composed by two trapezoids.

The formula for calculate the area of a trapezoid is:

$A=\frac{h}{2}(B+b)$

Where "B" is the larger base, "b" is the smaller base and "h" is the height.

Let be $A_f$ the area of the figure, $A_1$ the area of the trapezoid on the left and $A_2$ the area of the trapezoid of the right. Then the area of the figure will be:

$A_f=A_1+A_2$

$A_f=\frac{h_1}{2}(B_1+b_1)+\frac{h_2}{2}(B_2+b_2)$

Substituting values, you get:

$A_f=\frac{16units}{2}(25units+4units)+\frac{10units}{2}(25units+15units)=432units^2$

A bag contains 14 green, 12 orange and 19 purple tennis balls.

Nataliya [291]

Answer:

See explanation

Step-by-step explanation:

There are 14 green, 12 orange and 19 purple tennis balls in the bag,

$14+12+19=45$ balls in total.

A. The propbabilities that

a randomly chosen ball from the bag is green $=\dfrac{14}{45};$

a randomly chosen ball from the bag is orange $=\dfrac{12}{45}=\dfrac{4}{15};$

a randomly chosen ball from the bag is purple $=\dfrac{19}{45}.$

A probability model for choosing a tennis ball from the bag is

$\begin{array}{lccc}\text{Ball}&\text{Green}&\text{Orange}&\text{Purple}\\ \\\text{Probability}&\dfrac{14}{45}&\dfrac{4}{15}&\dfrac{19}{45}\end{array}$
