<h3><u>Dave is 96 years old.</u></h3><h3><u>Jim is 32 years old.</u></h3><h3><u>Bill is 64 years old.</u></h3>
d = 3j
j = 1/2b
64 = (d + j + b)/3
d = 3(1/2b)
d = 1.5b
64 = (1.5b + 1/2b + b)/3
Combine like terms.
64 = (3b)/3
Multiply both sides by 3.
192 = 3b
Divide both sides by 3.
64 = b
Because we have the value for b we can plug it into the other equations to solve for the other ages.
j = 1/2b
j = 1/2(64)
j = 32
d = 3j
d = 3(32)
d = 96
Using it's concept, it is found that the probability that the special ball is chosen is given by:
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of outcomes is given by the combination of k balls from the set of n balls, given by:
One ball is special, hence the probability the special ball is chosen is given by:

Answer:
$46,053
Step-by-step explanation:
- Convert 29% into a decimal, which is 0.29.
- Multiply $35,700 by 29% as a decimal (0.29), which is 10,353.
- Since the keyword is more, we want to add $35,700 and 10,353 (29% of $35,700). The answer will be $46,053.
