Answer:

-7x^2 + 5x + 12 AC = -84 factors = 12, -7

-7x^2 - 7x + 12x + 12

-7x (x + 1) + 12 (x + 1)

(-7x + 12) (x + 1)

The probability a randomly selected household owns corporate stock is 0.54. The probability a randomly selected household has no

34kurt

Answer:

30% probability a randomly selected household has no Internet access given the household owns corporate stock

Step-by-step explanation:

I am going to say that we have two events.

Event A: Owning corporate stock. So P(A) = 0.54.

Event B: Having no internet access. So P(B) = 0.3.

Since they are independent events, we can apply the conditional probability formula, which is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probabilitty of event B happening given that A happened. We want to find this.

$P(A \cap B)$ is the probability of both events happening.

Since they are independent

$P(A \cap B) = P(A)P(B) = 0.54*0.3$

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.54*0.3}{0.54} = 0.3$

30% probability a randomly selected household has no Internet access given the household owns corporate stock

Points S, L, and P on this grid represent the locations of the school, the library, and the park

Vlad [161]

The distance, in units, from the school to the library and then the distance from the library to the park is 15 units.

<h3>What is the length of any line on the graph?</h3>

The distance or length of any line on the graph,

D = √{(x₂ - x₁)² + (y₂ - y₁)²}

where,

d = distance/length of the line between point 1 and 2,

(x₁ , y₁) = coordinate of point 1,

(x₂ , y₂) = coordinate of point 2,

The distance from school to the library is SL, therefore,

$\rm SL = \sqrt{(4-0)^2 + (1-4)^2} = 5\ units$

The distance from library to the park is LP, therefore,

$\rm LP = \sqrt{(-4-4)^2 + (-5-1)^2} = 10\ units$

Now, the distance, in units, from the school to the library and then the distance from the library to the park is 15 units (10 units + 5 units).
