<u>Answer:
</u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution:
</u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled =
Time it will take to fill the pool = 748 hrs
Answer:
x=1
y=2
z=-1
Step-by-step explanation:
Add the first two equations: (this will be equation 4)
Multiply the first equation by 2:
Take the third equation and subtract the above equation.
Multiply that by 3:
Subtract equation 4:
For y+3z=-1, plug in values:
Plug in y and z values in first equation:
Answer:
Option A Ordinal
Step-by-step explanation:
The most appropriate level of measurements for this category is ordinal measurements. The ordinal measurement allows for the ordering of the data but differences cannot be found for them or finding differences is completely useless using this measurements.
Step-by-step explanation:
Plug in each value of x into the equation and find y:
