A line passes through the points (4,19) and (9,24). Write a linear function in the form y =Mx+b for this line

snow_lady [41]

Slope = y2-y1 / x2-x1
= 24-19/9-4
= 5/5
= 1

solve for b
y=1x+b
19=1(4)+b
19=4+b
15=b

the equation of the line is y=x+15

(1 point) Consider n=20 independent flips of a fair coin. Say that a changeover occurs whenever an outcome differs from the one

77julia77 [94]

Answer:

9.5

Step-by-step explanation:

There is no changeover in the first throw. The probability of each changeover is 1/2 and it doesnt depend on the other changeovers. The only thing that modifies each experiment is the result of the previous flip, but regardless of weather it was tails or heads, the probability will always be 1/2.

Since the coin is flipped 20 times and the first time there is no changeover, there are a total of 19 experiments. All of them independent and with probability 1/2. Therefore, the total amount of changeovers for 20 flips is a random variable with distribution Binomial B(19,0.5), the expected value of a Binomial B(n,p) is n*p. In this case, the expected value of changeovers for n=20 is 19*0.5 = 9.5.

The standard deviation tells us a. the average value of the scores. b. the relative standing of a particular score. c. the skewn

andreyandreev [35.5K]

We can say that the standard deviation tells us <u>the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.

<h3>What is the standard deviation?</h3>

A standard deviation (or σ) is a measure of how widely distributed the data is about the mean (μ). A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out. A standard deviation around 0 suggests that data points are close to the mean, whereas a high or low standard deviation indicates that data points are above or below the mean, respectively.

We use the following formula to compute the standard deviation:

$\sigma = \sqrt\frac{{\sum_{i=1}^{N}\left | x_i - \mu \right | }^2}{N}$

In this formula, σ is the standard deviation, $x_i$ is the data point in the set we are solving for, μ is the mean, and N is the total number of data points.

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

In the question, we are asked to tell what standard deviations tell us from the given options.

From the above discussion, we can say that the standard deviation <u>tells us the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.
