Complete question :
a researcher compared the Heights and shoe sizes for 50 men, selected at random. The equation shown describes a line of best fit for the data, where X is the shoe size and y is the height, in inches (y=1.6x + 58)
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches
Answer:
1.25
Step-by-step explanation:
Given the regression equation :
y=1.6x + 58
X = shoe size ; y = height
Using the equation, the approximate shoe size of a man with a height of 60 will be ;
60 = 1.6x + 58
60 - 58 = 1.6x
2 = 1.6x
2/1.6 = 1.6x / 1.6
x = 2 / 1.6
x = 1.25
Hence, approximate shoe size of a man with a height of 60 will be 1.25

Step-by-step explanation:
Answer:
160 ft^2
Step-by-step explanation:
First you have to find the width, then you find the area. To find the width with a percentage we do Part/ Total = %/100 and we cross multiply. We need to find the part so that is the unknown, we will call it 'w' for width
w/20 = 40/100 Now we cross multiply, the x and the 100 and the 20 and 40
w * 100 = 100w
20 * 40 = 800
Now we have 100w = 800 The next step is to divide both sides by 100 so we just have w
100x/100= w
800/100 = 8
w = 8
The width is 8
Now we find the area which is length x width
20 x 8 = 160
So the area is 160 ft^2
