Each of the 110 students in a statistics class selects a different random sample of 35 quiz scores from a population of 5000 sco

djverab [1.8K]

Answer:

Step-by-step explanation:

In this question, we are asked to select which of the options best answer the question.

We proceed as follows;

Using the information given,

Each of the 110 students in a statistics class selects a random sample of 35 Quiz scores

from a population of 5000 scores. They are not given the population mean and standard deviation.

Now, using these data, each student then construct a 90% confidence interval for µ which is the average Quiz score in the population of 5000 students.

By definition, the population mean values will definitely be within the limits of this

confidence interval.

Thus, the correct answer is, Option (c)

Solve for m pls? I'd seriously appreciate it!

Vilka [71]

Answer:

$m=-1$

Step-by-step explanation:

Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation $12m+6=2m-4$

Then, subtract 2m from both sides, which leaves the equation as $10m+6=-4$

Then, subtract 6 from both sides, this results with the equation $10m=-10$

Finally, divide both sides by 10, this will result in m=-1

What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?

IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

Plug in the points:

$m= \frac{10 - 0}{0 - (-2)}$

Simplify:

$m= \frac{10}{2}$

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.
