Suppose that 3 balls are chosen without replacement from an urn consisting of 5 white and 8 red balls. Let Xi equal 1 if the ith

Katarina [22]

Answer:

The joint probability mass function table is provided below.

Step-by-step explanation:

The experiment consist of drawing 3 balls from an urn containing 5 white and 8 red balls.

The random variable <em>Xi</em> is defined as follows:

<em>Xi</em> = 1; if the ith ball is white

<em>Xi</em> = 0; otherwise.

Then <em>X</em>₁ = the 1st ball is white and <em>X</em>₂ = the 2nd ball is white.

The sample space is as follows:

S = {(X₁ = 0, X₂ = 0), (X₁ = 0, X₂ = 1), (X₁ = 1, X₂ = 0), (X₁ = 1, X₂ = 1)}

Compute the probability of each event in the sample space as follows:

$P(X_{1} = 0, X_{2}= 0)=\frac{8}{13} \times\frac{7}{12}=\frac{14}{39}$

$P(X_{1} = 0, X_{2}= 1)=\frac{8}{13} \times\frac{5}{12}=\frac{10}{39}$

$P(X_{1} = 1, X_{2}= 0)=\frac{5}{13} \times\frac{8}{12}=\frac{10}{39}$

$P(X_{1} = 1, X_{2}= 1)=\frac{5}{13} \times\frac{4}{12}=\frac{5}{39}$

The joint probability mass function table is provided below.

What is the slope of the line?<br><br> A: 3<br><br> B: - 3<br><br> C: - 1<br><br> D: 1

Shtirlitz [24]

Answer:

Step-by-step explanation:

To find the slope of a line, we can use the slope formula:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

So, we will need to choose two points from the graph. Any two points will work.

Let’s choose (0, -1) and (1, 2).

So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:

$\displaystyle m=\frac{2-(-1)}{1-0}$

Evaluate:

$\displaystyle m=\frac{3}{1}=3$

Therefore, the slope of the line is 3.

Hence, our answer is A.

Select the graph that matches the function y= 3x + 7

Molodets [167]

Answer:

The first graph.

Step-by-step explanation:

The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.

From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.
