General formula to determine the equation of the liney - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slopeGiven:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =
Plug in the numbers
m =
m =
m =
m = 7
The slope is 7
Determine the line equationPlug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
Answer:
B (6,0) because when graphed it would make a 90° angle
The volume is 64 cm^3. To find volume you do L•W•H so you do 4•4•4=64
To answer this item, we let x be the number of hours per month that Mrs. Gleason should work. The total budget is equal to sum of the amount acquired by Mr. Gleason and Mrs. Gleason. The equation that would express this is,
4,500 = 900(4) + 9x
The value of x from the equation is 100. <em>Thus, Mrs. Gleason should work for 100 hours per month. </em>
Answer:
8.04% to 15.96%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
Suppose that you take a random sample of 259 people leaving a grocery store over the course of a day and find that 12% of these people were overcharged.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
The lower limit of this interval is:
The upper limit of this interval is:
So 8.04% to 15.96%
