Answer:
A. 0.009899
B. 0.005624
Step-by-step explanation:
Data:
Let the probability that an item is defective = 
The probability that the item is not defective = 
The probability that the fifth item is defective = 
= 0.009899
Probability that one in 5 items is defective = 0.005624
He used four apples to make an apple pie. you can simply divide 12 by 3. 1/3 of 12 apples would be 4. if you think about it 2/3 would be 8 apples, adding four more apples would be 12 apples making that 3/3.
That means that for every 2cm you measure in real life, you represent it as 1 unit on the graph
Remember, for
the x value of the vertex is
so
given
x value of vertex is -5
and
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1
comlete the square
remember if we do
(h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand
a=-1
c=-5
X/8=15/12
X=10
The answer Is 10
