no correlation because as the number of people who biys tickets it doesn affect the value of the grand prize since it is chosen before the amount of tickets are sold
x*5 - quarter amount
(x+15)*25- nickels amount
(x*5)+((x+15)*25)=735
5x+25x+375=735
30x=735-375
30x=360
x=360/30=12 - number of nickels
x+15=12+15=27 - number of quarters
CHECK
12*5=60 ¢
27*25=675 ¢
675+60=735 ¢ or $7.35
J get answer on this way:
1 inches =2,54 centimeters,
5 inches=12,7 centimeters,
50 inches=127 centimeters,
average= 12,7/4+127/4+5/4+50/40=48,67 centimeters
The mixture will test negative if the 6 individuall samples are negative.
Ther probability that one sample is negative is independent of the probabilities of the other samples.
Then, the probability of the six combined events (all negative) is equal to the product of the probabilities for each sample (each negative).
The probability for one sample to be negative is 1 - 0.11 = 0.89.
Then, the combined probability is [0.89]^ 6 = 0.497 ≈ 0.50
Answer: 0.50
Answer:
