Answer: C. 100
Step-by-step explanation:
If the large tank is flowing at a constant rate of -6 per minute then we have to know that the water is moving from the tank. So is asking how many water will be left in the tank after 25 minutes.
You could use the equation
y = -6x + 250 where y is the amount of water left in the tank and x is the number of minutes.
So if x is 25 then plot it in and solve for y.
y = -6(25) +250
y = -150 +250
y= 100
Answer:
15, 8, 13, 13
Step-by-step explanation:
(1) mean = Σx / n = 135 / 9 = 15
(2) range = highest value - lowest value = 21 - 13 = 8
(3) mode = 13 (most repeated value in data set)
(4) for 9 values in a data set, we have that (9 + 1) / 2 = 5th number
median = 13
