Answer:
Maria: (50 bulbs)/(2 hours) = 25 bulbs/hour
Lois: (45 bulbs)/(3 hours) = 15 bulbs/hour
Together: 25 + 15 = 40 bulbs/hour
(150 bulbs)/(40 bulbs per hour) = 3 3/4 hours
(3/4 hours)(60 minutes/hour) = 45 minutes
Total time: 3 hours 45 minutes
Awnser=0.75
You can first reduce this fraction by dividing both the numerator and denominator by the greatest common Factor of 27 and 36 using GFC(27,36)=9.
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
Per can cost 0.625 so if you multiply that by 6 you’ll get $3.75 as the total cost for the 6 cans.
