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
a- 2/10 divide the fraction by 6
b-2/17 divide the fraction by 3
0.11 is the least amount.
Answer:
f(x) = (x + 4)^2 - 5
Step-by-step explanation:
Parent function: f(x) = x^2
To show this in a way that may look more familiar, f(x) = 1(x - 0)^2 + 0
Vertex form: f(x) = a(x - h)^2 + k
We know a = 1, because the slope is the same as the parent function.
Vertex: (h,k)
We can see that the vertex of the graph is (-4, -5)
So h = -4 and k = -5
Now all we need to do is plug the variables into our equation.
f(x) = a(x - h)^2 + k
f(x) = 1(x + 4)^2 - 5
f(x) = (x + 4)^2 - 5
