Dr. Sunshine has 12 students in her class. She has given a test and is evaluating the performance of her class. The exam is worth 50 points. Eleven of the students scored between 45 and 50. One student scored 12. The best measure for Dr. Sunshine to get an idea related to the performance of the class is the: a. Median b. Variance c. Mean d. Mode

answerim :

n

step-by-step explanation:

im not sure but my dad knows

answer is  

a.

p = 78

step-by-step explanation:

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

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
