Answer:
The answer is A
Step-by-step explanation:
$20,000 • .12= $2,400

$20,000 - $7,200= $12,800
$12,800
Answer:
John have to pay back $23,327.50 at the end of two years
Step-by-step explanation:
Simple Interest (I) = (PRT) ÷ 100
where P = Principal, R = Rate, T= Time
I = ($150500 × 7.75 × 2) ÷ 100
I = ($2332750) ÷ 100
I = $23,327.50
It's the first one, an algebraic expression contains variables
Answer:
False, it is nowhere near Rio de Janeiro
Step-by-step explanation:
It is given the probability that a dancer like ballet is 0.35
So, P(B) = 0.35
It is given the probability that a dancer like tap is 0.45
So, P(T)= 0.45
The probability that he likes both ballet and tap is 0.30
So, 
the probability that the dancer likes ballet if we know she likes tap. This is the case of conditional probability.
So, 

= 0.666
= 0.67
Therefore, the probability that the dancer likes ballet if we know she likes tap is 0.67.
Option 3 is the correct answer.
