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:
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

Answer:
- Similar triangles
Step-by-step explanation:
Refer to attached
<u>Given:</u>
<h3>ΔEFG</h3>- EF =6 m, FG = 5m, EG = 7 m
- ∠F = 87°, ∠G= 58°, ∠E = 180° -(87°+58°) = 35°
- KL= 28 m, LJ = 24 m, JK = 20 m
- ∠J = 87°, ∠K = 58°, ∠L = 35°
<u>We can see that:</u>
- ∠F≅∠J, ∠G ≅ ∠K, ∠E ≅ ∠L
and
- KL/EG = LJ/EF = JK/FG = 28/7= 24/6= 20/5 = 4
So the corresponding angles are congruent and corresponding sides are similar
We can conclude that the triangles are similar
I think it is that I did some math and that was my end result if I did it right and read the question correctly
