Answer:
-10
Step-by-step explanation:
divide both sides by -4
simplify to v+8=-2
subtract 8 from both sides
v=-10
Variable A : 1, 2, 4, 4, 5, 6, 7, 9
Mode is the number that appears more frequently in the data set than other numbers.
1, 2, 5, 6, 7, and 9 only appeared once.
4 appeared twice.
So, the mode of the data set is 4.
Additional info:
mean = (<span>1 + 2 + 4 + 4 + 5 + 6 + 7 + 9) / 8 = 38 / 8 = 4.75
median = (4 + 5) / 2 = 9 / 2 = 4.5
range = 9 - 1 = 8</span>
Ok so... what wait weres the pic??
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.
