Theres probably a better solution but brute force is sometimes good enough
The area of the piece of paper is (25cm x 21cm) = 525 cm² .
There's no reason it should change when you bend the paper
into different shapes.
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

Answer: Option 'D' is correct.
Step-by-step explanation:
If there is difference between the sample mean and the population mean, then it is known as "Sampling error".
As we know that standard error of the mean is given by
and the sampling error refers to the difference in the value of sample mean and the value of population mean.
Hence, Option 'D' is correct.
