Step-by-step explanation:
I accept your challenge!
First we know that a equation of the line is a linear equation, and its equation is:
In this context, the slope, defined as the steepness of a line is characterized as the ratio of RISE (the difference in the y-coordinates, the vertical change) over the RUN (the difference in x-coordinates, the horizontal change).
Once we know two points where the line goes through, we can get the slope, once we know the change in y and x.
I will take as Point 1 and
as Point 2.
So,
Now we have to find the y-intercept:
To do so, think about the the points given and the nearly finished equation, we can find b with those two informations.
Our currently equation of the line is:
Using the points, take Point 1 as an example, it says that when , so plugging it in the equation:
Taking the Point 2
Now we found ! The equation is complete!
Answer: 0.2643
Step-by-step explanation:
Given : The proportion of adults are unemployed : p=0.077
The sample size = 300
By suing normal approximation to the binomial , we have
Now, using formula , the z-value corresponding to 26 will be :-
Using standard distribution table for z , we have
P-value=
Hence, the probability that at least 26 in the sample are unemployed =0.2643
