To determine the probability that both people chosen are females, we will use the rule of multiplication. 
Let event A = the event that the first person chosen is female; and let B = the event that the second person is female. 
To start, it is given that there are 10 students, 5 of them are females.  Therefore, P(A) = 5/10
After the first selection, there are 9 students, 4 of them are females. Therefore, P(A|B) = 4/9
Based on the rule of multiplication:

P(A∩B) = P(A) * P(A|B)
P(A∩B) = (5/10) (4/9)
P(A∩B) = 20/90
P(A∩B) = 2/9

The probability that both people chosen are females is 2/9.

Answer:  D) reflection across y = -x

Explanation:

When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).

When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is (x,y) \to (-y,-x)

So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).

Similarly, B(1,5) moves to B ' (-5, -1)

Finally, C(6,9) becomes C ' (-9, -6)

Lelu [443]

Answer:

\frac{n^{2}}{2a}

Step-by-step explanation:

  • Just split it up first \frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}
  • Then 9 divided by 18 can be simplified into the fraction 1/2
  • What can go into a and a^2 ? a itself right, so if you divide a by a you get 1, if you divide a^2 by a you get a
  • Same as the a fraction, if you divide n^3 by n you get n^2
  • \frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}=\frac{1}{2}\times \frac{1}{a} \times\frac{n^2}{1}=\frac{n^{2}}{2a}
