Answer:
10.
Step-by-step explanation:
(2+3+4+5+6) / 2
= 20/2
= 10.
Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20
P(A) = probability of event A, P(B) = probability of event B
P(A) = x is given to us
P(B) = y is also given
--------------------------
If A and B are independent, then neither event affects the other. If we know A happens, then that doesn't change the probability of B happening (vice versa).
So that means P(A|B) = P(A) = x and P(B|A) = P(B) = y
This points to the answer being P(B|A) = y which is choice A or the first answer choice
note: P(A|B) is read as "probability of A given that B has happened". It is known as conditional probability. The symbol between the A and B is not the letter i or L, it is a vertical pipe symbol to separate the letters.
Answer:
16/63
Step-by-step explanation:
8/9 * 2/7
Multiply the numerators
8*2 = 16
Multiply the denominators
9*7 = 63
Put the numerator over the denominator
16/63
