Answer:
f = .39
Step-by-step explanation:
d (v) = 2.15 v^2 / (64.4 f)
v = 40
d = 138
substitute these in
138 = 2.15 (40)^2 / (64.4 *f)
simplify
138 = 2.15 (*1600) / (64.4 *f)
138 = 3440 / (64.4 *f)
multiply each side by 64.4f
138 * 64.4 f = 3440
8887.2 f = 3440
divide by 8887.2
8887.2 f /8887.2= 3440/8887.2
f=.38707
to the nearest hundredth
f = .39
Answer:
12.2 gallons for $1.87, I would spend probably 2.87 for 24.4 gallons
-9/5 or -1.8
2 - - 3 = 5
-5 - 4 = -9
F(0) = -1/5
f(4) = 7/17
f(4) - f(0)
average rate of change = --------------
4 - 0
(7/17) - (-1/5)
average rate of change = ---------------------
4
52/85
average rate of change = ---------
4
average rate of change = 52/85 *4
average rate of change = 208/85
Step-by-step explanation:
16 data points.
the mean value is the sum of all data points divided by the number of data points :
13896/16 = 868.5
the median is the data point with half of the other data points being smaller and the other half being bigger.
as we have an even number of data points, we need to apply the extra rule :
the median is the mean value between the 2 middle points (where one half of the other data points is smaller than these 2, and the other half is bigger than these 2).
in our case we have 138 and 240.
the mean value between these 2 and therefore the median of the list is
(138 + 240)/2 = 378/2 = 189
