Answer:
Step-by-step explanation:
Given : The DJ's cost between $219.00 and $369.00 per night and the light shows cost between $159.00 and $309.00 per night.
To Find: If you are booking both a DJ and a light show, write a compound inequality that represents the possible total amount you would pay, x.
Solution:
Let x be the total amount for both a DJ and a light show
DJ's cost between $219.00 and $369.00 per night
The light shows cost between $159.00 and $309.00 per night.
Minimum cost for Dj and light show both =Minimum DJ cost +Minimum light show cost
= 219+159
= 378
Maximum cost for Dj and light show both =Maximum DJ cost +Maximum light show cost
= 369+309
= 678
So, Compound inequality:Minimum cost for Dj and light show both <x<Maximum cost for Dj and light show both
Compound inequality:
Hence a compound inequality that represents the possible total amount you would pay, x. is

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.
