The value of X is 11.

<u>Step-by-step explanation</u>:

Given,

F(X) = 3X + 5 --------(1)
F(X) = 38 ------------(2)

Equating eq(1) and (2),

⇒ 3X+5 = 38

⇒ 3X = 38-5

⇒ X = 33/3

⇒ X = 11

Lorico [155]

Given that Craig bought a treadmill for 400 dollars.

Useful life of the macine = x

Hence annual purchase cost spread over x years will be 400/x per year.

In addition, there is an annual maintenance cost of 36 dollars.

Hence Average annual cost in dollars = purchase cost per year+maintenance cost per year

= $\frac{400}{x} +36 \\= \frac{400+36x}{x}$

Hence answer for rational function is

either $\frac{400}{x} +36[tex]Or [tex]\frac{400+36x}{x}$

Alexxx [7]

Answer: $\dfrac{1}{100,000}$

Step-by-step explanation:

Given : The total number of digits in number system (0 to 9) = 10

The number of digits in a social security number = 9

After last four digits are printed, the number of digits remaining to print = 9-4=5

Since , repetition of digits is allowed, then the total number of ways to print 5 remaining digits is given by :-

$10\times10\times10\times10\times10=100,000$

Now, the probability of getting the correct Social Security number of the person who was given the receipt is given by:-

$\dfrac{\text{Number of correct code}}{\text{Total number of codes}}\\\\=\dfrac{1}{100,000}$
