Answer:
<u><em>The balance of the odds must be for spins of different colours. Therefore, 81/81 - 29/81, the odds of getting two different colours.</em></u>
0 because the number in the middle is the midpoint.
Answer:
19 houses
Step-by-step explanation:
90*(2/5)=36
90-36=54
54*(2/3)=37
54-37=19
Speed = distance / time
Speed = ?
Distance = 350km
Time = 5 hours
350km / 5hours = 70
He averages 70km/h
We're looking for the two values being subtracted here. One of these values is easy to find:
<span>g(1) = ∫f(t)dt = 0</span><span>
since taking the integral over an interval of length 0 is 0.
The other value we find by taking a Left Riemann Sum, which means that we divide the interval [1,15] into the intervals listed above and find the area of rectangles over those regions:
</span><span>Each integral breaks down like so:
(3-1)*f(1)=4
(6-3)*f(3)=9
(10-6)*f(6)=16
(15-10)*f(10)=10.
So, the sum of all these integrals is 39, which means g(15)=39.
Then, g(15)-g(1)=39-0=39.
