Answer:
the answer is either mean or median because you can find both of them given the data
7.0, 7.2, 7.4, 7.6, 7.8, 8.0
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.
6a^2 - 2 -6 a -5a = 0
6a^2 -11 a - 2 = 0
a = 2 , a= -1/6
