Answer:
0.29287
Step-by-step explanation:
You want to use the binomial cumulative distribution function (binomcdf). The purpose of this function is that it allows you to obtain the probability of observing less than or equal to x successes in n trials, with the probability p of success on a single trial.
x in this case is 182, n is 200, and p is 0.9005. Essentially by inputting these values, we find the probability that out of 200 passengers with a 0.9005 chance of getting on the plane, that 182 or less show up.
This gives us P(x <= 182) = 0.70713. (You need your calculator for this step, input the values above in the binomcdf function)
We want to find the probability of more than 182 passengers showing up though, so it would be 1 - 0.70713 = 0.29287.
Thus the probability that when 200 reservations are accepted for the flight, there are more passengers than seats available is 0.29287.
Answer:
Option C is correct
Step-by-step explanation:
Given: inequality is
To find: situation that can be represented by the given inequality
Solution:
Cost of Dunkin Donuts gift card with Daniel = $50
Amount spent by Daniel per day = $3.50
Cost of Dunkin Donuts gift card with David = $100
Amount spent by David per day = $6
Amount left with Daniel after x days =
Amount left with David after x days =
According to question,
Amount left with Daniel after x days > Amount left with David after x days
So, he inequality that satisfies the situation is
Option C is correct
Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29
