Answer: -571
Step-by-step-explanation:
-950 - (-571) = -379
-950 + 571 = -379
Hope this helps :)
52 cards in a deck. 4 of those are queens. 52/2=26 (total # of black cards), 2 red queens. Total + of cards you could possibly draw as the favored car = 28 out of 52...,
This is where i lose the probability. It's greater than 50%. I hope this helps.
8 x2 is 16; we have a negative sign, so that makes our answer -16
(a) The "average value" of a function over an interval [a,b] is defined to be
(1/(b-a)) times the integral of f from the limits x= a to x = b.
Now S = 200(5 - 9/(2+t))
The average value of S during the first year (from t = 0 months to t = 12 months) is then:
(1/12) times the integral of 200(5 - 9/(2+t)) from t = 0 to t = 12
or 200/12 times the integral of (5 - 9/(2+t)) from t= 0 to t = 12
This equals 200/12 * (5t -9ln(2+t))
Evaluating this with the limits t= 0 to t = 12 gives:
708.113 units., which is the average value of S(t) during the first year.
(b). We need to find S'(t), and then equate this with the average value.
Now S'(t) = 1800/(t+2)^2
So you're left with solving 1800/(t+2)^2 = 708.113
