Its b because the equation pretty much says that is fx is gx when x is subtracted by 2
Answer:
12.3693
Step-by-step explanation:
use distance formula
Answer:
P(C|Y) = 0.5.
Step-by-step explanation:
We are given the following table below;
X Y Z Total
A 32 10 28 70
B 6 5 25 36
C 18 15 7 40
Total 56 30 60 146
Now, we have to find the probability of P(C/Y).
As we know that the conditional probability formula of P(A/B) is given by;
P(A/B) =
So, according to our question;
P(C/Y) =
Here, P(Y) =
and P(C
Y) =
{by seeing third row and second column}
Hence, P(C/Y) =
=
= <u>0.5.</u>
The class needs to sell at least 20 tickets
Let x be the number of tickets that need to be sold in order to add up to $1000
Using the equation $700+$15x>=$1000
Subtract 700 from both sides and then divide each side by 15 to get 20.
