Answer:
so the answer will be 1
Step-by-step explanation:
An oil tanker can be emptied by the main pump in 5 hours.
An auxilary pump can empty the tanker in 14 hours.
If the main pump is started at 7pm, when should the auxilary pump be started
so that the tanker is emptied by 11pm?
:
Let t = no. of hrs to run the Aux pump
:
The main pump will run 4 hr (7 - 11 pm)
:
Let the completed job = 1; (an empty Tanker)
:
The shared work equation
4%2F5 + t%2F14 = 1
Multiply equation by 70 to get rid of the equation, results:
14(4) + 5t = 70
56 + 5t = 70
5t = 70 - 56
5t = 14
t = 14%2F5
t = 2.8 hrs to run the aux pump
:
2.8 hr = 2 + .8(60) = 2 hrs 48 min
:
Subtract 2:48 from 11:00 = 8:12 PM start the aux pump
;
;
Check solution
4/5 + 2.8/14 =
.8 + .2 = 1

Step-by-step explanation:
When you are multiplying mixed numbers it is best to change them to improper fractions if it is easier for you.
2 1/4=9/4
5 1/4=21/4
If you simplify it, it will be 11.8125

Mode is equals to 12. According to statistics, mode is defined as the number in a given list of number that has the most occurrence. In this scenario, the number 12 has appeared 4 times, hence 12 is the mode.
Median is also equals to 12. To get the median, you have to arrange the numbers from lowest to greatest and get the middle value.
Therefore, median and mode are the both equal to 12.
