Answer:
6 hours.
Step-by-step explanation:
Let t represent time taken by plant 1 in hours to release the waste.
Part of waste released by plant 1 in one hour would be
.
We have been given that two chemical plant 1 releases waste twice as fast as plant 2, so time taken by plant 2 to release the waste would be
.
Part of waste released by plant 2 in one hour would be
.
We are also told that together they fill the tank in 4 hours. So part of tank filled by both plants working together in one hour would be
.




Therefore, it will take 6 hours for the faster plant to fill the tank working alone.
Answer:
See below.
Step-by-step explanation:
The IQR is the difference between the upper quartile of a set of data and the lower quartile of the data.
It is a measure of the spread of the data.
y = -
x - 3
the equation of a line in ' slope intercept form ' is
y = mx + c
where m is the slope and c the y-intercept
here m = -
and c = - 3
thus y = -
x - 3 is the slope- intercept equation
