A raffle is held at MTHS ASB to draw for a $1000 plasma television. Two thousand tickets are sold at $1.00 each. Find the expect

Semmy [17]

The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).

So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5

This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)

ASHA 777 [7]

Answer:

1.15 miles per minute was the balls average speed

Step-by-step explanation:

4 x 60 = 240 minutes

276 miles ÷ 240 minutes = 1.15 miles per minute

What’s the correct answer

Sergio039 [100]

----------------------------------------------------------------------------
Find constant a.
----------------------------------------------------------------------------
Given that g(4) = 8

--------------------------------------
Substitute x = 4
--------------------------------------
g(4) = a(4)² + 24 = 8

16a + 24 = 8

--------------------------------------
Take away 24 from both sides
--------------------------------------
16a = 8 - 24

16a = -16

--------------------------------------
Divide by 16 on both sides
--------------------------------------
a = -1

Now that we know that a = -1, plug it back to the equation.

g(x) = -x² + 24

--------------------------------------
Find g(-4)
--------------------------------------
g(-4) = - (-4)² + 24
g(-4) = -16 + 24
g(-4) = 8

----------------------------------------------------------------------------
Answer: 8

Find the general solution of the following equation. Express the solution explicitly as a function of the independent variable.

Mashcka [7]

Answer:

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Step-by-step explanation:

Integration Rule:

$\int x^n dx= \frac{x^{n+1}}{n+1}+c$
$\int \frac1x dx= ln(x) +c$

Given differential equation is

$x^2 \frac{dw}{dx}= \sqrt{w}(2x+5)$

$\Rightarrow x^2 dw= \sqrt{w} (2x+5) dx$ [ multiplying dx both sides]

$\Rightarrow \frac{dw}{\sqrt w}= \frac{(2x+5)}{x^2} dx$ [ dividing $x^2\sqrt w$ both sides]

Integrating both sides

$\int \frac{dw}{\sqrt w}=\int \frac{(2x+5)}{x^2} dx$

$\Rightarrow \int w^{-\frac12} dw=\int (\frac{2x}{x^2}+\frac{5}{x^2} )dx$

$\Rightarrow \int w^{-\frac12} dw=\int \frac{2}{x}dx +\int\frac{5}{x^2} dx$

$\Rightarrow \frac{w^{-\frac12+1}}{-\frac12+1} =2ln x+5 \frac{x^{-2+1}}{-2+1}+c$ [ c is arbitrary constant]

$\Rightarrow 2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$
