Chapter 13.3, Problem 26PPS

(a)

To determine

To calculate:

The approximate combined area of corn and spinach fields

Answer to Problem 26PPS

The approximate combined area of corn and spinach fields is $66{\text{units}}^2$ .

Explanation of Solution

Given information:

  

Calculation:

Let the square in the chart represents the plot of farmland. On the farm, there are total six fields of the crops grown. The chart included the approximate areas for the field.

The approximate area of the Soybean field is $38{\text{units}}^2$ and approximate area of corn field is $28{\text{units}}^2$ . The approximate area of the two field combined is

  $\begin{array}{l}=38{\text{units}}^2+28{\text{units}}^2\\ =66{\text{units}}^2\end{array}$

The approximate combined area of corn and spinach fields is $66{\text{units}}^2$ .

(b)

To determine

To calculate:

The probability that chosen randomly plot is used to grow soybeans

Answer to Problem 26PPS

The probability that chosen randomly plot is used to grow soybeans is $0.16$ .

Explanation of Solution

Given information:

  

Calculation:

The approximate area of the Soybean field is $27{\text{units}}^2$ and approximate total area of farmland is $170{\text{units}}^2$ . The probability that chosen randomly plot is used for the soybean is

  $\begin{array}{l}=\frac{27{\text{units}}^2}{{\text{170 units}}^2}\\ =0.16\end{array}$

The probability that chosen randomly plot is used to grow soybeans is $0.16$ .
