Answer: p=0.711
Step-by-step explanation:
The binomial distribution probability formula :-
, where P(X) is the probability of success in x trials , p is the probability of success in each trial and n is the total number of trials .
Given : The probability of buying a movie ticket with a popcorn coupon is 0.711 and without a popcorn coupon is 0.289.
If you buy 21 movie tickets, we want to know the probability that more than 14 of the tickets have popcorn coupons.
Then, the event of success is tickets have popcorn coupons.
Hence, the parameter p for the given binomial distribution scenario : p=0.711
Answer:
x= −3/8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(7x−8x)+6=5(−2−7x)+4
3(7x−8x)+6=(5)(−2)+(5)(−7x)+4(Distribute)
−3x+6=−10+−35x+4
−3x+6=(−35x)+(−10+4)(Combine Like Terms)
−3x+6=−35x+−6
−3x+6=−35x−6
Step 2: Add 35x to both sides.
−3x+6+35x=−35x−6+35x
32x+6=−6
Step 3: Subtract 6 from both sides.
32x+6−6=−6−6
32x=−12
Step 4: Divide both sides by 32.
32x/32= −12/32
x= −3/8
