Answer:

So profit is denoted by Y
Selling price is denoted by X

Hencd we have Y= X + B

Where Be can be a constant for example how much he already sold or etc.

Explicit and Recursive Functions:

aleksandr82 [10.1K]

In this problem we need to find the value of a and b. So given that the function should be in the form f(n) = an + b and we know each value of n, then out goal is to find a and b.

For getting this purpose, we need to find a system of two equations (given that we have two unknown variables)

Therefore:

(1) f(0) = a(1) + b = 18
∴ a + b = 18

(2) f(1) = a(2) + b = 24
∴ 2a + b = 24

Solving for a and b we have:

a = 6
b = 12

Finally:

f(n) = 6n + 12

Tic-tac-toe: In the game of tic-tac-toe, if all moves are performed randomly the probability that the game will end in a draw is

Natasha2012 [34]

Answer:

$P(X \geq 1) = 1-P(X$

And if we find the individual probability we got:

$P(X=0)=(7C0)(0.127)^0 (1-0.127)^{7-0}=0.3865$

And replacing we got:

$P(X \geq 1) = 1-P(X$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=7, p=0.127)$
