Harrizon [31]

Logically, he would owe 14 less each week

Let x = # of weeks passed

Algebraic Expression: 141 - 14x =

Week 1: 141 - 14 = 127

Week 2: 141 - 14(2) = 113

Week 3: 141 - 14(3) = 99

etc.....

Need to find A and B, I already found C

Semenov [28]

I'm going to assume you've learn sin, cos, and tan. To find a you must do:
$sin^{ - 1} = \frac{a}{12}$
Once you find a, you can use the Pythagorean Theorem to find b:
${a}^{2} + {b}^{2} = {c}^{2}$
Or you can do:
$cos^{ - 1} = \frac{b}{12}$
You can find these functions on a scientific calculator. Let me now if you need more help.

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

Alexandra [31]

Answer:

[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]
