Using it's concept, the desired probability is:

P(Female|Junior) = 75%.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, there are 8 Junior Students, out of which 6 are Female, hence the probability is:

P(Female|Junior) = 6/8 = 0.75 = 75%.

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the

charle [14.2K]

Given :

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the

point B.

To Find :

The coordinates of B.

Solution :

Let, coordinates of point B is ( h , k ) .

It is given that M is the mid - point of the straight line joining points A and B.

Coordinates of M is given by :

$M = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\(6,5 ) = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\\dfrac{2+h}{2} = 6 \ , \ \dfrac{3+k}{2} = 5\\\\h = 10 \ ,\ k = 7$

Therefore, coordinates of point B is ( 10 , 7 ).

Twenty, which is 4 more than half, of the students in Bryan’s homeroom have tickets to attend the school’s musical. Choose Yes o

BARSIC [14]

One possible equation would be 20 = 1/2x + 4.

Let x be the number of students in his homeroom. 1/2x is half of the students in his homeroom. Four more than 1/2 would be 1/2x + 4. This is, or equals, the 20 students that have tickets.

Find the slope and y-intercept of -x + 2y = 3. I need help on working this problem out

natita [175]

Answer:

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

Step-by-step explanation:

A first order function has the following format:

$y = ax + b$

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.

We have the following equation:

$-x + 2y = 3$

We just have to rewrite this equation

$2y = x + 3$

$y = \frac{x+3}{2}$

$y = \frac{x}{2} + \frac{3}{2}$

Which means that

$a = \frac{1}{2}, b = \frac{3}{2}$

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$
