Answer:

B) 15/91

Step-by-step explanation:

Probability of a girl as first choice is ...

number of girls / total number of students = 6/14 = 3/7

Probability of a girl as second choice (given a girl as first choice) is ...

number of girls / remaining number of students = 5/13

Then the probability of the two events is the product of their individual probabilities:

(3/7)·(5/13) = 15/91 . . . . . matches choice B

In ΔCAB, if m∠A = 10x + 9, m∠B = 34°, and m∠C = 97°, what is the value of x?
Zolol [24]

<em>x = 4</em>

<em>Here is why:</em>

When adding up all angles of a triangle, they will be equal to 180.

Let's add ∠B and ∠C together.

34+97=131

Let's subtract it from 180, that will be the value of ∠A.

180-131=49

Now we can set ∠A equal to 49.

10x+9=49

Subtract 9 from both sides.

10x=40

Divide.

<u>x = 4</u>

Is -4c&gt;7;c=-2 a solution or inequality
FromTheMoon [43]
C = -2 will work as a solution.

We know this because of we substitute -2 into the equation:

-4(-2) > 7

8 > 7


It comes out true, because obviously 8 is greater than 7






Hope this helps :)
