Step-by-step explanation:
a. Construct a decision tree for Wile
The solution to the question has been attached.
b. What is the expected value of the new car?
= [(0.2 × $10,000) + (0.8 × $18,000)] - $22,000
= $2000 + $14400 - $22000
= $16400 - $22000
= -$5600
c. What is the expected value of the used car?
= [(0.4 × $4000) + (0.6 ×$9000] - $12000
= $1600 + 5400 - $12000
= $7000 - $12000
= -$5000
d. What is the expected value of leasing the car?
= [(0.1 × -$2000) + (0.9 ×0)] - $8500
= -$200 - $8500
= -$8700
Answer:
p = 0.513
Step-by-step explanation:
There are 212 families with exactly 3 children. So in all, there are 212*3 = 636 children.
Of those,
The number of girls is:
81 + 76*2 + 31*3 = 326
That is, 326 girls out of 636 children.
Then
Answer: 648 pull-ups
Step-by-step explanation:
Given
Max take 5.5 minutes to do 60 Pull-ups with a break in between
Similarly, it took 8 minutes for 120 pull-ups
Suppose the time taken for a single pull-up and break is x and y minutes
So, it can be written
Now, suppose max perform at this rate, and the total pull-ups are P in 30 minutes
Based on the function for the bounded area of the curve, the shaded area bounded by the curve and the x-axis between the points where x = -2 and x = 1 is 12 units².
<h3>What is the area of the shaded area?</h3>
To find the shaded area, you need to integrate the function of the bounded area as shown below:
= ∫(x² + 3) dx
This gives:
= (x³/3 + 3)
= (1 / 3 + 3) - (8 /3 - 6)
= 1/3 + 3 + 8/3 + 6
= 9/3 + 9
= 12 units²
In conclusion, shaded area bounded by the curve and the x-axis between the points where x = -2 and x = 1 is 12 units².
