The Ridgeport school district collected data about class size in the district. The table shows the class sizes for five
randomly selected kindergarten and seventh-grade
classes.

Based on these data, which statement is true?
O A. Every seventh-grade class has 12 more students than a
kindergarten class.
B. The average size of a seventh-grade class is larger but varies less
than that of a kindergarten class.
C. The recommended number of students in a kindergarten class is
20.
D. The average size of a seventh-grade class is larger and varies
more than that of a kindergarten class.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

gvfvhv

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
