Answer:
a) 
b) 
c) Yes.
Step-by-step explanation:
We have that:

And we have $10 free of taxes.
Making x= number of tires to buy, then we have that the total cost of tires is:

So, what we pay for taxes is given by:

a) Then, according to the above, we can write down the total cost before the discount as:

b) And the total cost after discounts, is then given by:

c) If the discount is added first, then less tax will be paid because the amount on which it is paid is lower. If the discount is added later, then the taxes will have been taxed on a higher amount, so it does matter whether they are added first or later.
Answer:
1.5 cannot represent a probability. A probability is always 1 or less.
Answer:
The probability is approximately one in a million (0.001%
).
It's a very little probability, so the manager would be really surprised.
Step-by-step explanation:
We have for this question to calculate with a binomial random variable, with n=6 and p=1/1200=0.00083
.
We have to calculate the probability of getting 2 hits in the sample of size 6.

The probability is approximately one in a million (0.001%
).
It's a very little probability, so the manager would be really surprised.
186,000 in scientific notation is:
1.86 x 10^5
When writing in scientific notation, the first number is any number less than 10. For the exponent, it is however many places the decimal point has been moved over. If it is positive, the number is large, you move the decimal over to the right. If it is negative, the number is smaller, you move the decimal over to the left.
In 186,000, you use 1.86 since it is less than 10. Now, you count however many places the decimal has been moved over from this number to make 186,000. In this case, it is 5 places, so that is the exponent.
