Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Write a probability model for this ex

allsm [11]

Answer:

We estimate to have 8.33 times the number 6 in 50 trials.

Step-by-step explanation:

Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.

$P(X=k) = \binom{50}{k}(\frac{1}{6})^k(\frac{5}{6})^{50-k}$

We will estimate the number of times that she spins a 6 as the expected value of this random variable.

Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.

Then , in this case, with n=50 and p=1/6 we expect to have $\frac{50}{6}$ number of times of having a 6, which is 8.33.

Answer:

$f(x) = -4x - 2$

Step-by-step explanation:

To derive the function rule in slope-intercept form, $f(x) = mx + b$ , we need to find the slope, m, and the y-intercept, b, of the graph given.

Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{0 -(-1)} = \frac{-4}{1} = -4$

m = -4

The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.

Substitute m = -4, and b = -2 into $f(x) = mx + b$ .

The function rule in slope-intercept form would be:

$f(x) = -4x +(-2)$

$f(x) = -4x - 2$

Use the expression for the slope from part B to write a general equation for the slope of any two points (a, b) and (c, d).

Dmitrij [34]

Using a slope value of 3, the general equation in point-slope form is: y - b = 3(x - a).

Recall:

Given the slope (m) of a line, we can write an equation in point-slope form of the line can be written if we know one of the points as, $y - y_1 = m(x - x_1)$ , where $(x_1, y_1)$ is a point on the line and m = slope.

From the question given, the slope gotten from part B is missing in this question. However, let's assume the slope (m) = 3.

Using one of the points, say (a, b), to write a general equation in point slope form, substitute $(x_1, y_1)$ = (a, b) and m = 3 into $y - y_1 = m(x - x_1)$ .

Thus:

$\mathbf{y - b = 3(x - a)}$
