Answer:
8.47 Hours
Step-by-step explanation:
Allen can take 16 hours, while
Brianne can take 18 hours;
Therefore, in 1 hour Allen will complete a fraction of 1/16, while
in 1 hour Brianne will complete a fraction of 1/18
When working together, in 1 hour they will complete a fraction of (1/18+1/16)
= 17/144,
Therefore; to complete the whole project working together, they will take;
144/17 = 8.47 hours
Tim has 2 times as luke
t=2l
they have 29 goether
t+l=39
subsitute
2l+l=39
3l=39
divide by 3
l=13
subsitue
t=2l
t=2(13)
t=26
tim has 26 and luke has 13
I don't know how many marble Tim has but probably all of them since alll must die and then the marbles go to Time
Answer:
The value of x is approximately 0.3684.
Step-by-step explanation:
Given:
We need to solve the proportion.
Solution:
Now we can see that;
In given equation one number is fraction and other number is whole number.
Now To make whole number into fraction we will divide by 1.
hence the whole number will be equal to;
Now the new equation will be;
Now by cross multiplication we get;
Now dividing both side by 19 we get;
Hence the value of x is approximately 0.3684.
Answer:

Answer:
Expected return for site A = $9.6 million
Expected return for site B = $12.4 million
according to the above results the company should choose SITE B because it has higher Expected return
Step-by-step explanation:
Given;
For site A,
Site A net if successful = $30 million
Success probability = 0.4
Site A loss if not successful= -$4 million
Probability of not successful = 0.6
For site B.
Site B net if successful = $60 million
Success probability = 0.3
Site B loss if not successful= -$8 million
Probability of not successful = 0.7
To estimate the expected return on an event with outcomes X1 and X2 with probabilities p1 and p2
E = X1(p1) + X2(p2)
Substituting for site A
E = 30(0.4) - 4(0.6)
E = $9.6 million
Substituting for site B
E = 60(0.3) - 8(0.7)
E = $12.4 million
Therefore, according to the above results the company should choose site B because it has higher Expected return
