[<em>We assume that each piece of apple is identical</em>]

{{{{This part for little more explanation:

There are 12C6 ways that 6 fruits can be taken from the bag

which is equal to

=12!/{(12-6)!*6!}

=(12*11*10*9*8*7*6!) / (6!*6!)

=665280 / (6*5*4*3*2*1)

=924 ways

}}}}}

Your main solution here:

Similarly there are 6C5 ways to get exactly 5 apples out of 6 fruits which is equal to,

=6! / {(6-5)! *5! }

=(6*5!) / (1!*5!)

=6 ways>>>>>>>ANSWER

NOTE: nCx=n! / [(n-x)! *x!]  where n=total items and x= no of items choosen

{n is written up in the upper left of C and x is written as Subscript}

How can Kendra determine if the function is actually linear?
pashok25 [27]

Answer:

D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Step-by-step explanation:

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-4}{3-2}=\dfrac{5}{1}=5

2. Points (3,9) and (4,16). Rate of change:

\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{16-9}{4-3}=\dfrac{7}{1}=7

The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.
