Answer:

C and e

Step-by-step explanation:

there are two sides and its pretty much completely random on which side it lands on 2 sides = 1/2 probrability for each side and for the dice there are 3 odd numbers and 3 even numbers so thats half and half of the dice therefore 1/2 probrability

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 $\dfrac{30!}{6!(24)!}$ .

White raven [17]

Answer :

1 (i).
$slope \: = - \frac{1}{6}$
(ii).
$midpoints \: = (1 \: \: \frac{17}{2} )$
(iii) .
$distance \: = \sqrt{37}$
2(i).
$slope \: = 2$
$gradient \: = - \frac{1}{2}$
I Hope it helps :)
