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.
Since the left side of the equation says f(5), then plug in 5 for x.
So, it is:
-4|5| + 3
= -20 + 3
= 23
Answer: 30.1
Step-by-step explanation:
Cups of raisins mixed= 10.33
Cups of pretzels mixed= 12.25
Cups of chocolate mixed= 7.50
When each ingredients is rounded to the nearest tenths, it will be:
Cups of raisins mixed= 10.3
Cups of pretzels mixed= 12.3
Cups of chocolate mixed= 7.5
Total trail mixed by John= 10.3 + 12.3 + 7.5 = 30.1
30.1 cups was mixed together by John.
Answer:
b. 42.875 units³
Step-by-step explanation:
The volume of a cuboid is the product of its edge dimensions (length×width×height):
(3.5 units)(3.5 units)(3.5 units) = 3.5³ units³ = 42.875 units³
Solve:
3y - 9x = 24
Let's solve for x.
3y − 9x = 24
Step 1: Add -3y to both sides.
−9x + 3y + −3y = 24 + −3y
−9x = −3y + 24
Step 2: Divide both sides by -9.
−9x / - 9 = -3y + 24 / -9
x = 1 / 3y + -8 / 3
Answer: =======> x = 1 / 3y + -8 / 3
Graph: 3y - 9x = 24 ==========> y = 3x + 8
Interception points of: 3x + 8
x intercepts: ======> ( -8/3, 0 )
y intercepts: =======> ( 0, 8 )
Answer: =======> x = 1 / 3y + -8 / 3
Hope that helps!!!! : )
