Well 4 out of the 5 are odd.  So the probability the first digit is odd is (4/5) since that digit is no longer available, then the probability the second digit is odd is (3/4), then for the third (2/3), then the forth (1/2).

So to find the first four being odd is (4/5)*(3/4)*(2/3)*(1/2) = 24/120 = .20

Which radical expression is in simplified form A. 11y/sqrt3 B. sqrt6/5y C. sqrt17/sqrt4 D. sqrt25/18
Mkey [24]

Answer:  \frac{\sqrt{6}}{5y}

Step-by-step explanation:

The given radical expressions are:

A. \frac{11y}{\sqrt{3}}\\\text{It is not completely simplified ,}\\\text{since denominator is radical, we need to rationalize it first to simplify. }\\\\B.\frac{\sqrt{6}}{5y}\\\text{It is completely simplified ,}\\\text{since its denominator is not radical and 6 is not a perfect square. }\\\\C. \frac{\sqrt{17}}{\sqrt{4}}\\\text{It is not completely simplified ,}\\\text{since denominator is radical, we need to rationalize it first to simplify. }\\\\\\\\D. \frac{\sqrt{25}}{18}=\frac{5}{18}\\\text{Hence, expression D was not completely simplified .}

The sum of 2 trinomials is 7x^2 - 5x + 4. If one of the trinomials is 3x^2 + 2x - 1, then what is the other trinomial?
Hunter-Best [27]
We can subtract the sum of the two trinomials by one of the trinomials.
(7x²-5x+4)-(3x²+2x-1)
Let's look at each part.
7x²-3x²=4x²
-5x-2x=-7x
4-(-1)=5
So, the trinomial should look like:
4x²-7x+5
So, C. 4x²-7x+5 is the other trinomial.

A merchant buys a television for $125 and sells it for $75 more.What is the percent of markup?
cestrela7 [59]
Since he sold it for $75 more,

% Mark Up = Mark Up/ Cost Price  x 100%

% Mark Up =   75 / 125 x 100%      =   0.6  x 100% = 60%

Percent Mark Up = 60%
Hope this helps :)
