Whenever you sign a lease for an apartment, you typically have to pay a security deposit before you even move in; this is in cas
likoan [24]
The answer is F(x) = 900x + 600

Let x stands for the number of months

The apartment is rented for $900 a month, so every month it will be paid 900x (for example, for one month (x = 1), you will pay 900 · 1 = $900, for three months (x = 5), you will pay 900 · 5 = $4500, etc.)

A security deposit is paid only once and is not dependent on the number of months. So, its value is only 600. 

These two values must be summed up because both must be paid, nothing is to subtract. Therefore, the function f(x) for  apartments that rent for $900 a month and a security deposit of $600 is:
f(x) = 900x + 600

There are 5 red pens and 10 black pens in a cup. If a person randomly selects 3 of them, what is the probability that they're al
kolbaska11 [484]

Answer:

option a)

0.286

Step-by-step explanation:

Given that,

number of red pens in cup = 5

number of black pens in cup = 10

number of pen randomly selected = 3

There are 5 red pens and 10 black pens. So there are 5 + 10 = 15 pens in all.

probability of having all red pens = (5/15 x 4/14 x 3/13)

                                                       = 2/91

probability of having all black pens = (10/15 x 9/14 x 8/13)

                                                           = 24/91

probability that all pen are of same colour = 24/91 + 2/91

                                                                      =  2/7

                                                                      ≈ 0.286
