Step-by-step explanation:
2L+2W= L*L+W*W= 2*2+2*2= 8
L= lenght
W= width
(the formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together)
w=2l-p÷2; w=p-1÷2; w=p-21÷2 w=p-2w÷21????
Answer:
The perimeter of crater lake is 17.27 miles.
Step-by-step explanation:
Given as :
The shape of the lake is like a circle
The diameter of lake = d = 5.5 miles
∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles
Let The perimeter of crater lake = p miles
<u>Now, As we know</u>
The perimeter of circle =
× diameter
the value of
= 3.14
Or, p =
× d
Or, p =
× 5.5 miles
Or, p = 3.14 × 5.5 miles
∴ p = 17.27 miles
So, The perimeter of circle = perimeter of lake = p = 17.27 miles
Hence, The perimeter of crater lake is 17.27 miles. Answer
Answer:
The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Step-by-step explanation:
The least square regression line is used to predict the value of the dependent variable from an independent variable.
The general form of a least square regression line is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:

Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:


Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
