Answer with explanation:
Equation of Linear Regression line is
y=1.14 x + 3.805
A line of regression is that line which passes through none of the points, few points or all the points in the two dimensional coordinate plane.It tells value of one variable when another variable is known.
for, x=30
y=1.14 × 30 +3.805
y=34.20 +3.805
y=38.005
y=38 (approx)
So, Ordered pair is , (30,38)
Option B
Answer:
1:200
5.6 cm^2 : y (as actual area)
y = 200 mutifly 5.6 cm^2
y= 1120 cm^2
We know 1m =100cm
so, 1m^2 =100cm x 100 cm = 1000cm^2
y= 1120 m^2/ 100x100
= 0.112 m^2
Step-by-step explanation:
Answer:
x = 26
Step-by-step explanation:
x + 104 = 5x
104 = 4x
x = 26
