The value of x in the given quadratic equations is either -2.7 or -11.3.

<h3>What are quadratic equations?</h3>

A quadratic equation is a second-degree algebraic equation in x. ax² + bx + c = 0, where a and b are coefficients, x is the variable, and c is the constant term, is the quadratic equation in its simplest form.

Given first equation, y = x²- 6x + 4 second equation, y = x +1

Put the value of y in the first equation to get

x + 1 = x² - 6x + 4

Solving this equation

x² - 7x + 3 = 0

Using quadratic formula,

x = - b ± \frac{\sqrt{(b^{2}- 4ac)}}{2a}

x = - 7 ±  \frac{\sqrt{(-7)^{2}- 4(3)}}{2}

x = - 7 ± 4.3

Therefore in the given quadratic equations, the value of x can be either -2.7 or -11.3

The number of customers waiting for gift-wrap service at a department store is an rv X with possible values 0, 1, 2, 3, 4 and co
julia-pushkina [17]

Answer:

P[X=3,Y=3] = 0.0416

Step-by-step explanation:

Solution:

- X is the RV denoting the no. of customers in line.

- Y is the sum of Customers C.

- Where no. of Customers C's to be summed is equal to the X value.

- Since both events are independent we have:

                         P[X=3,Y=3] = P[X=3]*P[Y=3/X=3]

              P[X=3].P[Y=3/X=3] = P[X=3]*P[C1+C2+C3=3/X=3]

        P[X=3]*P[C1+C2+C3=3/X=3] = P[X=3]*P[C1=1,C2=1,C3=1]        

              P[X=3]*P[C1=1,C2=1,C3=1]  = P[X=3]*(P[C=1]^3)

- Thus, we have:

                        P[X=3,Y=3] = P[X=3]*(P[C=1]^3) = 0.25*(0.55)^3

                        P[X=3,Y=3] = 0.0416
