In order to conduct an experiment five subjects are randomly selected from a group of 48 subjects how many different groups of f
exis [7]

Answer:

1,712,304 ways

Step-by-step explanation:

This problem bothers on combination

Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;

48C5 = 48!/(48-5)!5!

48C5 = 48!/43!5!

48C5 = 48×47×46×45×44×43!/43!5!

48C5 = 48×47×46×45×44/5!

48C5 = 205,476,480/120

48C5 = 1,712,304

Hence this can be done in 1,712,304ways

PLZ help<br> What system of linear inequalities is shown in the graph?
GarryVolchara [31]

In order find the Inequalities, First we need to Find the Equations of Both the Lines.

<u>Equation of First line :</u>

It is passing through the Points (0 , 2) and (4 , 0)

⇒ Slope = \frac{2 - 0}{0 - 4} = \frac{-2}{4} = \frac{-1}{2}

⇒ Equation of the First Line : y - 2 = \frac{-1}{2}(x)

⇒ Equation of the First Line : x + 2y = 4

<u>Equation of Second Line :</u>

It is passing through the Points (1.5 , 0) and (0 , -3)

⇒ Slope = \frac{0 + 3}{1.5 - 0} = \frac{3}{1.5} = 2

⇒ Equation of the Second Line : y + 3 = 2x

⇒ Equation of the Second Line : 2x - y = 3

As the Shaded Area of the First Line is away from the Origin :

⇒ x + 2y ≥ 4

As the Shaded Area of the Second Line is towards the Origin and it is a Dotted line :

⇒ 2x - y < 3

So, the System of Linear Inequalities are :

⇒ x + 2y ≥ 4

⇒ 2x - y < 3
