Answer:
y =
Step-by-step explanation:
a) Let Area be the independent variable and Price of the homes sold be dependent on the area.
Let x represents the area and y represents the price.
We will plot the data in excel using trend line function.
The model so obtained is:
Rounding values to the nearest hundredth, we get
15/30:2/30
15/30=2/30x
divide by 15/30
7.5 is x
5.
we have.
11x=½(16x+16+50)
22x=16x+66
22x-16x=66
6x=66
x=66/6
x=11
6.
118°=½(6x-11+181)
236=6x+170
6x=236-170
x=11°
7.
34°=½(arcAK-arc LN)
34×2=(110-arc LN)
arc LN =110-68
arc LN=42°
8.
<L=½(arc EN-arc KM)
<L=½(139°-73°)
<L=33
