The experiment probabilities are listed below:

One:  2 out of 20 = 2 / 20 = 0.1  or 10%

Four:  5 out of 20 =  5 / 20 = 1 / 4 = 0.25 = 25%

The theoretical probability of any single number is 1 out of 6 or about 17%.

The experimental probability for ones was less than and for fours it was greater than the theoretical probability.

Carol is single and has an adjusted gross income of $32,785. She claims one exemption of $8200. What is her tax due?
LenKa [72]

Answer

A = 3321

Step-by-step explanation:

The reason for this answer is to get the Taxable income, you go by this equation AGI - (Exemptions + Deductions) since there is no deductions here we leave that part out. Subtract the AGI (32785) - 8200 the Exemption and you get 24585 then if we look on the chart, she is single and she falls under the answer of 3321!

Hope this helps, sorry I am a little late. I just got this answer too. :)

Which of the following is equal to the average of (x+2)^2 and (x-2)^2
Digiron [165]

C

expand factors, sum like terms and divide by 2

(x + 2)² + (x - 2)² = x² + 4x + 4 + x² - 4x + 4 = 2x² + 8

\frac{1}{2}(2x² + 8 ) = x² + 4 → C
