Answer: 1 1/4 cups of vegetable oil left over.
Step-by-step explanation: 1/2 cup for Cakepops and 1.5 times (3/4 cup) for cup cakes.
2 1/2 - 1/2 - 3/4
4a^2-12b=
<u>4(a^2-3b)
</u>
multiply 4 with the parenthesis, and you can see it will be 4a^2-12b<u>

A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.
<h3>
What is a confidence interval?</h3>
Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.
A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.
You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.
Finally, look up the resulting Z or t score in a table in order to find the level.

Answer: 2.5 hours or 2 hr and 30 min
Step-by-step explanation:
We can set up an equation to find how many hours you can park.
2.5+4x=12.5
The 2.5 comes from the base fee. The 4x is the hourly rate, where x is hours. The 12.5 is the total amount of money you have.
Since we have our equation, we can solve for x.
4x=10
x=2.5
You can park for 2.5 hours, or 2 hours and 30 min.
