Answer:
<em>Predicted height: 57.42 inches</em>
<em>Residual: 2.58 inches</em>
Step-by-step explanation:
<u>Regression Equation</u>
The regression equation for the height of the children (Hgt) and their age (Age) is given by the expression
Hgt = 24.3 + 2.76(Age)
We must compare the predicted value of the equation vs the real data point Age=12, Height=60
Computing the predicted height
Hgt = 24.3 + 2.76(12)
Hgt=57.42 inches
The residual is the difference between the real data point and the predicted value
R=60-57.42
R=2.58 inches
Let's solve your equation step-by-step.
-9 ÷ 3 + b = -1
Step 1: Simplify both sides of the equation.
<u>−9</u>
3
+b=−1
−3+b=−1
b−3=−1
Step 2: Add 3 to both sides.
b−3+3=−1+3
b=2
Answer:
b=2
Answer:
k=3

Answer:
y = 0x + 2
Step-by-step explanation:
y = 2 is the same as y = 0x + 2. The slope of this line is zero (0) (the line is horizontal).
In slope-intercept form, the equation of this line is y = 0x + 2, which may be left as is or changed to y = 2.
Answer:
1240 cm
Step-by-step explanation:
Diameter = 2 * radius
The radius is 620, making the diameter 620 * 2 = 1240
