Answer: 0.45

Step-by-step explanation:

P (X = 3) is listed in the table as: 0.15

P (X = 0) is listed in the table as: 0.3

Note: "or" means to add, "and" means to multiply

P (X = 3) or P (X = 0)

0.15 + 0.3 = 0.45

Which equals the product of (x – 3)(2x + 1)? 2x² – 7x-3 2x² – 5x-3 3x-2 0 6x²

lina2011 [118]

Answer:

2x² - 5x - 3

Step-by-step explanation:

Given

(x - 3)(2x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 1) - 3(2x + 1) ← distribute parenthesis

= 2x² + x - 6x - 3 ← collect like terms

= 2x² - 5x - 3

Which of the graphs below correctly solves for x in the equation −x2 − 3x − 1 = −x − 4?

gtnhenbr [62]

Answer:

Graph of quadratic opening downward and linear sloping up to the left. They intersect at point negative 3, negative 1 and point 1, negative 5

Step-by-step explanation:

we have

$-x^{2} -3x-1=-x-4$

we can separate the expression above into two equations

$y=-x^{2} -3x-1$ ----> equation A

This is a quadratic equation ( vertical parabola) open downward (the leading coefficient is negative)

$y=-x-4$ ----> equation B

This is a linear equation with negative slope (decreasing function).so linear sloping up to the left

The solution of the original expression are the x-coordinates of the intersection point both graphs

using a graphing tool

The intersection points are (-3,-1) and (1,-5)

see the attached figure
