The correct option is B.
W(x)=24x+8
Answer:
The steps to finding the upper and lower quartiles are given in the first choice.
1. Order the data from least to greatest. If you don't do this, the data is random.
2. Find the median - you will do this so that you can find the midpoint of the data set (half of of the data is smaller and half of the data is larger).
3. Find the lower quartile - this is the half of the lower half of numbers; think of it as breaking the lower half of the data into 2 sections.
4. Find the upper quartile - this is the half of the greater half of numbers; this will break the upper half of the data into 2 sections.
According to the problem we start with 6000 gal of E10 which means there is 10% of ethanol in this 6000, with ths information we can calculate the amount of ethanol already in the mixture:
The relationship between ethanol and total fluid can be represented like this:
Based on this relationship we can build the one that we are looking for:
the total solution will be:
where X is the E5 solution volume
and the TotalEthanol would be:
where E5ethanol (5% Ethanol 95% Gasoline) would be:
Now replacing in the relationship we found before:
Solving for X:
We should mix 1500 gal of E5 to make an E9 mixture
Answer:
Future value, A = $10,500
Step-by-step explanation:
<u>Given the following data;</u>
Principal = Rs. 10,000
Interest rate compounded half yearly = 10% = 10/2 = 5%
Time = 1 year
To find the future value, we would use the compound interest formula;
Where;
- A is the future value.
- P is the principal or starting amount.
- r is annual interest rate.
- n is the number of times the interest is compounded in a year.
- t is the number of years for the compound interest.
Substituting into the equation, we have;
<em>Future value, A = $10,500</em>
Answer: b= 22
you plug in a point from your table,(chose the first point) and it should be 46=17(4)-b. you solve for b and you should get your y-intercept as 22.
