The average credit card debt for american is between $11,000 and $17,000. how could this be written using a margin of error

[μ-error, μ + error]

[14000- 3000, 14000 + 3000]

Step-by-step explanation:

We write it how an interval, where the center of the interval is the mean, thus

[μ-error, μ + error]

First we calculate the mean

μ = (11000+17000)/2

μ = $14000

And the error is the absolute value of the difference between the mean an either extreme values

error = |14000 -17000| = |14000 - 11000| = 3000  

Then

[14000- 3000, 14000 + 3000]

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
