2x+7=3x+3 is a linear equation with on solution
In this case, 7 is being added to the odometer which already reads 78. If you add 7 to 78, you get 85. Meaning y = 85!
Step-by-step explanation:
slope interception formula is
y-y1=m(x-x1)
where m is m=y-y1/x-x1 in this case m=-2 because the line we are trying to find is parallel to the given one y=-2x-6 where slope k=-2
so the final equation would be
y-1=-2(x-(-4))
y-1=-2x-2*4
y=-2x-8+1=-2x-7
Answer:
.70 8.40 divided by 12 because a dozen is equal to 12
Answer:
n = 22
Step-by-step explanation:
Using
n = p(1-p)(Zc/E)²
From table E = 0.2 while p= 0.37
So substituting
We have n= 22.4
Thats a sample size of approximately 22
