Recall that the expected value is another way to refer to µ. What is really being asked is how many calls are expected to come in during a 5-minute interval. The following conversion factor can be used to find the mean number of calls per minute when given the mean number of calls per hour. calls hour · 1 hour 60 minutes Convert 24 calls per hour to calls per minute. 24 calls hour · 1 hour 60 minutes = calls per minute To find the expected number of calls per a 5-minute interval, multiply the mean number of calls per minute by 5. (5 minutes)(mean number of calls per minute) = 5 = calls per 5 minutes

noun

the practice of taking someone else's work or ideas and passing them off as one's own.

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
