Suppose that a computer software company has 30
LekaFEV [45]

Answer: \dfrac{30!}{6!(24)!}

Step-by-step explanation:

Given : The total number of programmers in the company = 30

The company wants to select a group of 6 programmers to work on a  particular project.

Since the order of selecting them does not matters , therefore we use combinations.

The number of combinations of r things taken from n things is given by :-

^nC_r=\dfrac{n!}{r!(n-r)!}

here, n= 30 and r= 6

So the number of different ways to form they could select a group of 6 would be ^{30}C_{6}=\dfrac{30!}{6!(30-6)!}

=\dfrac{30!}{6!(24)!}\\\\=\dfrac{30\times29\times28\times27\times26\times25\times24!}{(720)24!}=593775

i.e. Total ways =593775

In terms of factorials , the number of total ways to form they could select a group of 6 is \dfrac{30!}{6!(24)!} .

Give the equation pls
Sveta_85 [38]

Answer: The equation of the line x + 3y = 9 can be written in the slope intercept form y = mx + c as . The slope of this line is . As the product of the slope of perpendicular lines is equal to -1, the slope of a line perpendicular to x + 3y = 9 is 3.

Step-by-step explanation:

ok im super sorry if this doesn't help I'm not partially skilled when it comes to this type of stuff and if it doesn't even relate to the question sorry qwq I really hoped it help and if it didnt just tell me and i can delete it
