Answer: $11.60

Explanation: First, you want to do 15.1 - 9.3 to find what half of his weekly allowance is, and that would be 5.8, AKA $5.80. Next, you want to multiply that number by 2, which would be 5.8(2) to get 11.6, or your final answer, $11.60.

Solve for x sim b (10, 0.75) for x = 5
Aleksandr-060686 [28]

The value of x \sim B (10, 0.75) for x = 5 is 0.06

<h3>How to solve the probability?</h3>

The expression is given as:

x \sim B (10, 0.75)

This means that:

n = 10

p = 0.75

The probability is then calculated as

P(x)= ^nC_x * p^x *(1 - p)^{n-x

This gives

P(5)= ^{10}C_5 * 0.75^5 *(1 - 0.75)^5

Evaluate the combination expression

P(5)= 252 * 0.75^5 *0.25^5

Evaluate

P(5)= 0.06

Hence, the value of x \sim B (10, 0.75) for x = 5 is 0.06

Find the x-intercepts for the parabola defined by the equation below. y = x2 - 9x + 18
8_murik_8 [283]

Answer:

Option D is the correct answer

Step-by-step explanation:

The x intercepts of the parabola are the solutions of the equation. These points can be determined either by graphical method or by solving the quadratic equation with any of the methods of solving a quadratic equation.

In order to use the graphical method, values of x are picked and substituted into the equation to get corresponding values of y. The y values are plotted against the x axis and the parabola (downward) is drawn. The points where it cuts the horizontal axis become the solutions of the equation

y = x^2 - 9x + 18

Solving the equation by using the factorization method,

x^2 - 9x + 18 = 0

x^2 - 6x - 3x + 18 = 0

x(x-6)-3(x-6)

(x-6)(x-3) = 0

x -6 = 0 or x -3 = 0

x = 6 or x = 3

The x-intercepts are (3, 0) and (6, 0)
