Someone help please! Determine the intercept of the line that passes through the following points
1 answer:
Answer:
x: (-5.0)
y: (0, -17.5)
Step-by-step explanation:
The x-intercept of the line is when y=0. In the table is the point (-5,0). This is the x-intercept.
To find the y-intercept, find when x=0. Write an equation for the table in y=mx + b. Find the slope between two points first.
The slope is -3.5. So the equation is
y - 7 = -3.5(x--7)
y - 7 = -3.5 (x+7)
y - 7 = -3.5x - 24.5
y = 3.5x - 17.5
Since it is in y=mx+b, b= -17.5 and this is the y-intercept.

Answer:
1.165.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
. So
So the correct answer is:
1.165.
