From the excel plotting, we see that the least square regression equation is given by:
m=(7.25-2.65)/(2009-1978)
m=0.15
thus the equation will be:
0.15(x-0)=y-2.65
y=0.15x-2.65
b] Using the equation we can approximate the hourly wage in 2025 as follows:
x=(2025-1978)=47
y=0.15(47)-2.65
y=7.05-2.65
y=4.4
The plot is as shown in the figure:
Hope it can solve you problem... :)
Answer:
x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
![\frac{small}{large}=\frac{3}{6}=\frac{(x-3)}{(x+1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bsmall%7D%7Blarge%7D%3D%5Cfrac%7B3%7D%7B6%7D%3D%5Cfrac%7B%28x-3%29%7D%7B%28x%2B1%29%7D)
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
<u>Answer:</u>
True
<u>Step-by-step explanation:</u>
Step 1: We can plug 106 into x in the equation x - 62 = 44.
Step 2: Check if 106 - 62 = 44. It’s correct, so the answer is TRUE!!
