You send out 12,000 emails and 300 are opened. what is your open rate? (open rate is opens as a percentage of sent emails.)

Amount of emails which are sent = 12,000
Amount of emails which are opened = 300

the question asked the open rate as a percentage. 

Hence, we can write open rate as,
        Open rate = (number of opened emails / number of sent emails) x 100%
                          = (300 / 12,000) x 100%
                          = 2.5 %

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
