Answer:
75 less student tickets than adult tickets. The total is 625 tickets. So the student and adult tickets have to equal 625 when added.
Step-by-step explanation:
Student tickets: 275
Adult tickets: 350
Both 5 and 17 are prime, so the ratio cannot be simplified :)
Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
Domain of a Function is a Set of Values under which the Function is defined or a Set of Values which satisfy the respective Function.
The Given Function is : f(x) =
The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.
When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)
According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero.
⇒ 2x + 10 > 0
⇒ 2x > -10
⇒ x > -5
In Set Builder Form it is Expressed as { x | x > -5 }

The expected value is the sum of the probablity of each outcome multiplied by the "value" of each outcome.
Its sort of like a special average.
In your case each outcome has probability <span>16</span></span></span>
. and you get 5 dollars when you roll 3 or 6 when you roll something else.
So the expected value is
<span><span>06</span>+<span>06</span>+<span>56</span>+<span>06</span>+<span>06</span>+<span>56</span>=<span>106</span>=<span>53</span></span>
.
This means loosely that if you played this game a lot you should
expect to win on average about 1.66 dollars, while you payed 3 to play
it. Clearly this is a great idea if you want to lose money.
