Answer:
So the best option is c) 0.1912
Step-by-step explanation:
For this case we have a standard deck of 52 cards and we consider the experiment without replacement.
So then we have 13 heart cards and 52-13 = 39 NOT heart cards
In order to find the probability that we select a heart card in the first extraction we have this:
Now for the second extraction we have a total of 51 cards since we select one at the first extraction and we can find the probability of not heart like this:
And for this case we can assume that we have independent events since the extraction of the first and second card are not related events and assuming this we have this probability:
So the best option is c) 0.1912

It does refer to whether the data measures what it claims to measure.
Hope i helped you!
The axis of symmetry is 2. If you look at the function <span>f(x)=(x-2)^2+3, you flip the sign of the "-2" (it would become a positive 2) that is in the parentheses and it becomes the x-coordinate of the vertex (AKA the axis of symmetry). I know it's sort of confusing, but I hope you get what I mean!</span>
Answer:
t = X - Xt - 1
Step-by-step explanation:
X=1+t/1-t
Multiply both both sides by 1 - t
X(1 - t) = 1 + t
X - Xt = 1 + t
t = X - Xt - 1
