The 11/2 cup of black beans is extraneous info, you just need to know that it provides 15% of the potassium you need daily. With that info, you know that you need 85% more to fulfill your daily value. If we say x is the total amount of potassium needed, then we can set up the equation:
x * 0.85 = 2890
Then we can solve for x by dividing both sides by 0.85. The answer, then, is 2890/0.85 = 3400 mg.

We have been given that the test scores on a final exam are normally distributed with a mean of 74 and a standard deviation of 3. We are asked to find the probability that a randomly selected test has a score higher than 77.
First of all, we will find z-score corresponding to sample score 77.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we need to find .
We will use formula to find the probability greater than a z-score of 1.
Using normal distribution table, we will get:
Therefore, the probability that a randomly selected test has a score higher than 77 would be 0.15866.
Answer:
21 G = 390miles
G = 390/21
G = 18.57
gallons of gas should he expect to use to travel 635 miles to Daytona Beach
= 635/18.57
=34.19
<em><u>Hence,</u></em><em><u> </u></em><em><u>3</u></em><em><u>4</u></em><em><u> </u></em><em><u>gallons </u></em><em><u>is </u></em><em><u>the </u></em><em><u>correct</u></em><em><u> answer</u></em>
