Answer:
length=1.05m
perimeter=2.7m
Step-by-step explanation:
18900 in m^2=1.89 m^2
area=length*width
1.89=length*1.8 m
length=1.89÷1.8
length=1.05 m
perimeter=(l+w) 2
perimeter=(1.05+1.8)2
perimeter=2.85×2
perimeter=2.7 m
The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975
C) A risk-neutral person would pay $80 or less to play the lottery.

<span>Simplifying
-3.7 + w = 9.24
Solving
-3.7 + w = 9.24
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '3.7' to each side of the equation.
-3.7 + 3.7 + w = 9.24 + 3.7
Combine like terms: -3.7 + 3.7 = 0.0
0.0 + w = 9.24 + 3.7
w = 9.24 + 3.7
Combine like terms: 9.24 + 3.7 = 12.94
w = 12.94
Simplifying
w = 12.94</span>
