Answer:
mean: 12
median: 12
mode: 19 and/or 7
range: 6 (I think, I'm not great at range)
standard deviation: 20 (I think, not great at this either)
hope this helped even a little bit
After doing some quick calculations, we can determine that X = −35.9
I hope this helps! :)
Answer:
60ft
Step-by-step explanation:
Let's x, y be the width and length of the surrounding rectangle. Since the area is 450 sq feet, this means xy = 450 or y = 450/x
The perimeter of this rectangle is (since there are 3 sides only)
f(x,y) = 2x + y
This is something we need to minimize. We can start by substituting y = 450/x
f(x) = 2x + 450/x
Let's take the first derivative of this function and set it to 0
y = 450 / 15 = 30ft
so the minimum perimeter that needs taping over is
f(x,y) = 2x + y = 2*15 + 30 = 60ft
At hour 9 the river is 18 feet deep.
At hour 18 the river is 21 feet deep.
From 9 to 18 hours is 9 hours difference.
From 18 to 21 feet is a 3 foot difference.
The average rate of change is the change in depth divided by the change in time:
3 feet / 9 hours = 0.3 feet per hour. ( Rounded to the nearest tenth)
Answer:
that would be 3.5
