A school conducts 27 test and 36 weeks assume the school conducts test at a constant rate what is the slope of the line that rep

frosja888 [35]

Slope equals rise over run. Rise is referring to y values and run is referring to X values. so if they say tests are the Y axis then you use 27 as the rise and 36 as the run. once you have the fraction it is simply reducing the fraction.
27/36= 9/12 = 3/4

Find the slope of the line that goes through (0, 2) and (4, −2).

zmey [24]

M = (y2 - y1) / (x2 - x1)

m = (-2 - 2) / (4 - 0)

m = -4 / 4

m = -1

The slope of the line that goes through (0, 2) and (4, -2) is -1.

g Recall the example about community college students and gender. Statistics students surveyed 135 students at Tallahassee Commu

bixtya [17]

Answer:

They can either decrease the confidence level or increase the sample size, that is, survey more students.

Step-by-step explanation:

The width of a confidence interval is given by:

$M = z*\frac{\sigma}{\sqrt{n}}$

In which z is the critical value correponding to the confidence level(higher confidence level, higher z is), $\sigma$ is the standard deviation of the population and n is the size of the sample.

The students realize that this interval contains a large margin of error. What can they do to make a narrower interval?

Looking at the formula for M, they can either decrease the confidence level or increase the sample size, that is, survey more students.
