<span>-24=2(x-4)
Use distributive property
-24=2x-8
Add 8 to both sides
-16=2x
Divide 2 on both sides
Final Answer: -8=x</span>
Answer: she should get 30.45 miles per gallon with her new tyres.
Step-by-step explanation:
After buying the Dunlop tires at a local Goodyear store, the salesperson told her that her mileage would increase by 5%.
If before this purchase, Maria was getting 29 mpg, it means that the amount by which her mileage will increase is
5/100 × 29 = 0.05 × 29 = 1.45 miles per gallon.
Therefore, the number of mileage that she should be getting with the new tires would be
29 + 1.45 = 30.45 miles per gallon.

Using the binomial distribution, it is found that there is a 0.03125 = 3.125% probability that all the nickels will land with heads facing up.
For each coin, there are only two possible outcomes, either it lands on heads, or it lands on tails. The landing of a coin is independent of other coins, hence, 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:
- 5 nickels, hence .
- They are equally as likely to land on heads or tails, hence
The probability that all the nickels will land with heads facing up is P(X = 5), hence:
0.03125 = 3.125% probability that all the nickels will land with heads facing up.
