Answer:
p=0.8765
Step-by-step explanation:
Let the following variables be represented as below:
Total Set,t=17
Def,d=3
Not Def,n=14
Purchases,p=8
The number of ways the hotel can receive at least one defective set in a purchase of 8 sets is calculated using the combination:-

So the proability of getting at least one defective unit is 0.8765
Answer:
t-t
Step-by-step explanation:
Answer: 21y^5-28y^4+49y^3
If the remainder isn't necessarily zero, we add C_1y^2+C_2y+C_3, which covers all possible remainders when dividing by a polynomial with leading term in y^3.
Step-by-step explanation:
(3y^2-4y+7)(7y^3) =
21y^5-28y^4+49y^3
Answer:
Step-by-step explanation:
This is a system of inequalities such that:

Let's start by solving for y for both equations:
Equation 1:

Equation 2:

Now if we substitute the 2nd y into the first equation we obtain:

Now we will solve for the second equation using the first result of y and we obtain:

And so our solution for the system of equations is:

As well as:

In order to get -140, one number has to be negative and one number has to be positive. And these two numbers when added together give you a -4, which means the greater of these numbers has to be negative.
Try guess and check strategy by listing possible factor combinations for -140 and see which one works!
