What is P(A), the probability that the first student is a girl? (3/4)What is P(B), the probability that the second student is a girl? (3/4)

What is P(A), the probability that the first student is a girl? (3/4)What is P(B), the probability that the second student is a girl? (3/4)What is P(A and B), the probability that the first student is a girl and the second student is a girl? (1/2)

The probability that the first student is a girl is (3/4), likewise for the 2nd 3rd and 4th it's still (3/4). The order you pick them doesn't matter.

However, once you're looking at P(A and B) then you're fixing the first position and saying if the first student is a girl what's the probability of the second student being a girl.

A point K is on the perpendicular bisector of a segment with endpoints at H and J. What must be true about point K? It is equidi

kykrilka [37]

Answer:

$K$ is equidistant from $H$ and $J$ .

Step-by-step explanation:

Given that the point $K$ which is on the perpendicular bisector of the line segment having endpoints at $H$ and $J$ .

The given situation can be represented as the diagram as attached in the answer area.

Referring to the $\triangle HOK, \triangle JOK$ :

$\angle HOK = \angle JOK=90^\circ$ (As it is the perpendicular bisector)

$OH = OJ$ (As it is the perpendicular bisector)

Also, the side $OK$ is the common side.

Therefore by $S-A-S$ congruence, $\triangle HKO\cong \triangle JKO$

As per the properties of congruent triangles:

Side $HK$ = Side $JK$

$HK$ and $JK$ are nothing but the distance of the point $K$ from the end points $H$ and $J$ which are proved to be equal to each other.

Therefore, we can conclude that:

$K$ is equidistant from $H$ and $J$ .

The sum of two numbers is −48 and their difference is 17. Find the numbers.<br> pls asap

Hatshy [7]

Answer:

a = -15.5, b = -32.5

Step-by-step explanation:

Let's say the first number is a, and the second is b.

a + b = - 48

a - b = 17

If you add both equations, you get 2a = -31, because the

+b and -b cancel each other.

So you would get a + a = 2a, then -48 + 17 = -31

2a = -31

--- ---

2 2

Divide both sides by 2 to get a by itself.

a = -15.5

Then let's go to the next equation (a - b = 17)

Plug in a..

-15.5 - b = 17

+ 15.5 + 15.5

------

-b = 32.5

--- ------

-1 -1

b = -32.5

Hope this helps.
