Answer:
Step-by-step explanation:
We are given that
Point (1,0)
We have to find the equation of tangent line to the given graph.
Differentiate w.r.t x
Substitute x=1
Slope-point form:
By using this formula
The equation of tangent to the given graph
The sample size is too small. The company is trying to determine the percent of people in Mississippi that would purchase the product. To make a prediction for the entire state of Mississippi, they should survey more than just 24 people. A random survey should be created and given out across the state.
So if the line is linear we can use slope intercept form to find the equation of the points: y=mx+b
To calculate m, the slope we subtract two of the points (I’ll use the first two):
(-1, 1)
(4, 0)
This equals 0-1/4+1, which simplifies to -1/5
So the slope is -1/5 and we can put that into slope intercept form along with a point to get b, the y-intercept.
So, y=-1/5x+b
Now we substitute x and y with a point.
1=-1/5(-1)+b
1=1/5+b
b=4/5
So the equation is:
y=-1/5x+4/5
I hope this helps!
