Answer:
513 turkey sandwiches were sold.
Step-by-step explanation:
Let's use to represent turkey sandwiches and
to represent steak sandwiches.
= turkey sandwiches
= steak sandwiches
total sandwiches that were sold
dollars that were made
Now that we know what (steak sandwiches) equals, we plug it in to an equation to find
.
Now, we subtract 5,550 from BOTH sides so we can get x by itself.
Next, we divide both sides by 2, so x is bare.
Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.
I hope this helps! :)

Answer:
17.80% probability that all of them are wearing their seat belts.
Step-by-step explanation:
For each driver stopped, there are only two possible outcomes. Either they are wearing their seatbelts, or they are not. The drivers are chosen at random, which mean that the probability of a driver wearing their seatbelts is independent from other drivers. So we use the normal probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Police estimate that 25% of drivers drive without their seat belts.
This means that 75% wear their seatbelts, so
If they stop 6 drivers at random, find the probability that all of them are wearing their seat belts.
This is .
17.80% probability that all of them are wearing their seat belts.
