Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
The slope is negative. the slope is calculated by using “rise over run”. in the problem, you go down 2 and over 1. so your answer is -2/1 or -2
Answer:
The y-intercept is 1/3.
Step-by-step explanation:
The equation given is in slope-intercept form. Recall that in slope-intercept form:
<em>m </em>is the slope while <em>b</em> is the y-intercept.
Therefore, -2/9 would be the slope while 1/3 would be the y-intercept.
so to solve you hav eto make the equation;
you have to put one equation on one part of the equal side and the other on the other, then solve
Answer:
If x <2, simplify some answer, i hope you find it
honestlyyyy do hope lol
