Answer:
Melinda's loan will be equal to the value of the car after 10 months.
Step-by-step explanation:
We are given,
Balance on the loan is given by, y = 10,000 - 250x.
Also, Value of the car is given by, y = 8,000 - 50x.
Since, it is required to make Melinda's loan equal to the value of the car.
We have,
10,000 - 250x = 8,000 - 50x.
i.e. 250x - 50x = 10,000 - 8,000
i.e. 200x = 2,000
i.e. x = 10.
Thus, Melinda's loan will be equal to the value of the car after 10 months.
Let's write an equation and solve for x
12 1/2 = 5x + 3 1/3
rewrite the mixed fractions as improper fractions and with denominator 6
75/6 = 5x + 20/6
subtract 20/6 from both sides
55/6 = 5x
divide both sides by 5 to isolate x
11/6 = x
That is 1 and 5/6 pounds per each of the friends
To check:
<span>12 1/2 =?= 5(1 5/6) + 3 1/3
12 1/2 =?= 55/6 + 3 1/3
12 1/2 =?= 25/2
12 1/2 = 12 1/2
Hope this helps</span>

Using it's formula, it is found that the mean of the discrete random variable is given by:
B. 30.47.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Hence, considering the table, the mean of the discrete distribution is:
E(X) = 23 x 0.16 + 25 x 0.09 + 26 x 0.18 + 31 x 0.12 + 34 x 0.24 + 38 x 0.21 = 30.47.
Hence option B is correct.
