Answer: 1

Step-by-step explanation:

Given : A bag contains 7 apples and 5 oranges.

Then , the total number of pieces of fruits = $7+5=12$

We know that the number of n things taken x at a time is given by:-

$^nC_x=\dfrac{n!}{x!(n-x)!}$

Then, the number of ways you can get 7 apples:-

$^{7}C_7\times^5C_0=\dfrac{7!}{7!(7-7)!}\times\dfrac{5!}{0!(5-0)!}\\\\=1\times1=1$

Hence, the number of ways you can get 7 apples =1

What does it mean when there is an open circle on a graph?

VladimirAG [237]

It means that the value will not be included. So if the open circle coincides with 2 on the x-axis then your limit will have x<2, which also means that the function is not continuous.

Answer:

0 People initially had the cold.

6 People will have it after 2 days.

Step-by-step explanation:

To find out how many people had it initially, plug 0 in for x (implying 0 days later.)

C= 1*3(0)

C= 1*0

C=0

Nobody had the cold initially.

To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)

C= 1*3(2)

C= 1*6

C=6

Therefore 6 people had the cold after 2 days.

I hope this helps!

let a,b,c,d be four integers (not necessarily distinct) in the set {1,2,3,4,5}. the no. of polynomials x^4+ax^3+bx^2+cx+d which

Eddi Din [679]

By either long or synthetic division, it's easy to show that

$\dfrac{x^4+ax^3+bx^2+cx+d}{x+1}=x^3+(a-1)x^2+(-a+b+1)x+(a-b+c-1)-\dfrac{a-b+c-d-1}{x+1}$

The quartic will be exactly divisible by $x+1$ when the numerator of the remainder term vanishes, or for those values of $a,b,c,d$ such that

$a-b+c-d-1=0$

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.
