At every company meeting, the president speaks for 20 minutes and then takes questions from her employees. Let q represent the n
ololo11 [35]

Answer:

t = 20 + q (minutes)

Step-by-step explanation:

The meeting consists of speaking and Question & Answer (Q&A) sessions.

Speaking session = 20 minutes

Q&A session = q minutes

Total number of minutes spent for the two sessions = 20 + q (minutes)

But total number of minutes meeting lasted = t minutes.

Therefore, t = 20 + q (because they both represent the total number of minutes the meeting lasted)

Answer:

the median is 80.5

Step-by-step explanation:

first we put them in order

75,76,77,79,80,81,85,86,90,91

the median is the middle number...however, in cases where there are an even number of numbers, ur gonna have 2 middle numbers....so u take the average of those 2 numbers...basically, u add them and divide by 2.

So we have 2 numbers in the middle.....we add them and divide by 2 to get the median.

(80 + 81) / 2 = 161/2 = 80.5 <== the median
