Find the average value of the function on the given interval.<br> f(x)=(2x-1)1/2; [1,13]
Leni [432]

Answer:

The average value of the function on the given interval 6.5.

Step-by-step explanation:

Consider the given function is

f(x)=\dfrac{2x-1}{2}

We need to find the average value of the function on the given interval [1,13].

f(x)=\dfrac{2x}{2}-\dfrac{1}{2}

f(x)=x-0.5

The average value of the function f(x) on [a,b] is

Average=\dfrac{1}{b-a}\int\limits^b_a {f(x)} \, dx

Average value of the function on the given interval [1,13] is

Average=\dfrac{1}{13-1}\int\limits^{13}_{1} {x-0.5} \, dx

Average=\dfrac{1}{12}[\dfrac{x^2}{2}-0.5x]^{13}_{1}

Average=\dfrac{1}{12}[\dfrac{(13)^2}{2}-0.5(13)-(\dfrac{(1)^2}{2}-0.5(1))]

Average=\dfrac{1}{12}[78-0]

Average=6.5

Therefore, the average value of the function on the given interval 6.5.

A wheel has 38 numbers, 1, 2, 3, . . . , 38. a player picks a number and bets $20. the wheel is spun, and if the player's number
Rainbow [258]

Answer: $63.16

<u>Step-by-step explanation:</u>

Probability of winning is \frac{1}{38}.  Which means that it would take 38 spins to win one time.

Since the average player spins 60 times then the number of wins is:

\frac{1}{38}x 60 = 1.58

So, the average person wins: ($700 + $20) x 1.58 = $720(1.58) = $1136.84

and the average person spends: $20 x 60 spins = $1200.00

The net gain for the house is $1200.00 - $1136.84  = $63.16
