Answer:
Step-by-step explanation:
It is given that the regression equation
predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).
The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.
Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.
and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.
<em>Answer:</em>
<em>C = 12.88</em>
<em>Step-by-step explanation:</em>
<em>If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by </em><em>π</em><em> to get the diameter.</em>
<em>C = π d = π · 4.1 = </em><em>12.88</em><em>053cm </em>

Answer:
D <u><em>Because if you substitute 4 into the equation for x and cross multiply, you get 224 = 224.</em></u>
Step-by-step explanation:
When you cross multiply, you get 14×16=224, and 224÷4=56.
Answer:
22 rooms
Step-by-step explanation:
If two gallons of paint covers 3 rooms then you need to divide 15 gallons of paint by 2 gallons of paint = 7.5 gallons of paint. then you need to multiply 7.5 gallons of paint by 3 rooms = 22.5..... so that means you can paint 22 full rooms.
