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

Please help me with this!!!!!
pav-90 [236]

Answer:

B

Step-by-step explanation:

The line on the left has a negative slope of - 1 and a y- intercept at 2

The line has a closed circle at x = 1, thus

- x + 2 for x ≤ 1

The line on the right has a positive slope of 1 and a projected y- intercept at 1

The start of the line has an open circle at x = 1 indicating it cannot equal 1, thus

x + 1 for x > 1

The definition for the function is B
