Problem Statement
We are asked to find the critical t-value for a confidence level of 80% and sample size of 17.
Method
To solve this, we simply need to do two things:
1. Calculate the degrees of freedom:
The sum of the percentages of milk and dark chocolate needs to equal 100%.
Since dark chocolate is 25%, then milk chocolate must be 75%
Now we can set up a proportion:
75% = 3 lbs
25% = X lbs
Dark chocolate = (3 x 25%) / (75% x X) = 1 lb
Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
