There are 13 girls and 4 more students that are boys that made an A grade. Thus there are 13+4=17 students that are either girls or A students.

The probability of choosing a girl or A student is 17/30.

Determine the value of the ?
goblinko [34]

Answer:

x^{2} y^{3}

Step-by-step explanation:

Using the Quotient rule:

\frac{a^{m}}{a^{n}} = a^{m - n}

We can subtract the exponents of x and y:

\frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{(6 - 4)} y^{(10 - 7)}

Therefore, \frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{2} y^{3}

Which inequality is true? 1.5 greater-than 2 and one-half
Travka [436]

The inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have inequalities given:

1.5 > 2\dfrac{1}{2}

or

1.5 > 2.5  (false)

1/2 > 0.5

0.5 > 0.5 (false)

-2.5 > -1.5 (false)

-3 \dfrac{1}{2} > -4.5

-3.5 > -4.5  (true)

Thus, the inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.

Evaluate -a - 12a 2 for a = -1
Serhud [2]
The answer is -11
You put "-1" in place of all the "a"s and get 
-(-1) - 12(-1)^2
-(-1) is just 1, and (-1)^2 is "1"
We are then left with 1-12(1) which is 1-12 which is -11
