Answer:
a=112
b=6
c=280
Step-by-step explanation:
you just plug the number into the equation
28x=y
where x is the gallons
and y is the total miles
56*(4+15/60)
56*(240+15)/60
56*(255)/60
238 miles
F(x)=x^2+3x+5
f(3+h)=(3+h)^2+3(3+h)+5
f(3+h)=9+6h+h^2+9+3h+5
f(3+h)=23+9h+h^2
Answer:
x = 4

A correlation coefficient of -0.975 on a linear regression indicates: D. One variable has a strong relationship with the other.
<h3>What is Correlation Coefficient?</h3>
Correlation coefficient, r, is a measure of how strong the relationship between two variables is.
A correlation coefficient, r, that is closer to 1 or -1 signifies a strong relationship between two variables and vice versa.
Therefore, a correlation coefficient of -0.975 on a linear regression indicates: D. One variable has a strong relationship with the other.
