Answer: 278.30 pounds (if the gasoline does not contain ethanol)
317.12 pounds (if the gasoline does contain ethanol)
Step-by-step explanation:
If the truck averages 12 miles per gallon, then in 170 miles it consumes:
170mi/12mi = 14.17 gallons.
We know that for one gallon consumed, the carbon dioxide emitted into the atmosphere is 19.64 pounds. (assuming it does not contain ethanol)
Then for 14.17 gallons consumed, we have a emission of:
14.17*19.64 pounds = 278.30 pounds
I the gasoline contains ethanlol, for a gallon the emiision is around 22.38 pounds.
In this case the total emission is:
14.17*22.38 pounds = 317.12 pounds
Using the binomial distribution, it is found that there is a 0.81 = 81% probability that NEITHER customer is selected to receive a coupon.
For each customer, there are only two possible outcomes, either they receive the coupon, or they do not. The probability of a customer receiving the coupon is independent of any other customer, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- For each customer, 10% probability of receiving a coupon, thus
. - 2 customers are selected, thus

The probability that <u>neither receives a coupon is P(X = 0)</u>, thus:


0.81 = 81% probability that NEITHER customer is selected to receive a coupon.

Answer:
18 tablespoons of honey
Step-by-step explanation:
Since you need 3 tablespoons of honey for 3 loaves and you know you need 24 loaves you could do...
24/4 which equals 6
You can do this since there's 4 loaves made per 3 tablespoons of honey
Then you could do..
3x6
which gives you 18 tablespoons of honey
