Answer:
86 cm²
Step-by-step explanation:
<u>1) Calculate the area of the square</u>
Therefore, the area of the square is 400 cm².
<u>2) Calculate the area of the circle</u>
we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
Therefore, the area of the circle is 314 cm².
<u>3) Subtract the area of the circle from the area of the square</u>
Therefore, the area of the shaded region is 86 cm².
I hope this helps!

Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Step-by-step explanation:
1. What is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Water collected - 6/7
Water used for cleaning bicycle = 1/2 × 6/7 = 6/14
Water used for each houseplant =>6/14 ÷ 3 = 2/14 = 1/7
