Answer:
It's C.7
Step-by-step explanation:
Use the foil method
Slope-intercept form is y=mx+b. our goal is to get y by itself on one side of the equation.
2x-3y+1=0
2x+1=3y
3y=2x+1
y=(2/3)x+1/3
That is the same function but in slope-intercept form.
25*8.14=?
Multiply the cost of the book per person ($8.14) by the number of people (25).
Answer:
Modification has not reduced the number of accidents.
Step-by-step explanation:
A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
Difference -2 0 1 -4 -4 -3 0 -8
Mean of differences 
Standard deviation of differences = 
Formula of paired t test :
Df = n-1 = 8-1 =7
t critical> t calculated
So, We failed to reject null hypothesis
Hence modification has not reduced the number of accidents.
