It's saying that 95% of the time the comparison from test to retest is 96% reliable.

so I would take (0.95+0.96)÷2= 0.955

then 73×0.955=69.715

then 73-69.715=3.285

so I would range the possible true score between 69.715 and 76.285

also written as 73 ± 3.285

Multiply (x-1)(x³+4x²+4x-1) and combine like terms. Explain how you reached your answer.
Hitman42 [59]

Answer:

x⁴+3x³ -5x +1

Step-by-step explanation:

To multiply this we are going to <u>multiply each term of the binomial by each term of the polynomial.</u>

(x-1)(x^{3}+4x^{2}  +4x-1)\\=x^4+4x^3+4x^2-x -x^3-4x^2-4x+1

Now we are going to <u>combine like terms (this means we are going to sum up terms with the same exponent)</u>

x^4+4x^3+4x^2-x -x^3-4x^2-4x+1 = x^4 +(4x^3-x^3)+(4x^2-4x^2)+(-x-4x)+1\\=x^4+3x^3-5x+1

Thus, the answer is x⁴+3x³ -5x +1

Write as a mixed number in lowest terms 7.25
Verizon [17]
7.25 is the same as 7 \frac{25}{100} written as a mixed number. However, .25 is \frac{1}{4} of 100.

In this case, while rewriting your mixed number, 7.25 is the same as 7\frac{1}{4}, so that would be your answer.

7.25 ⇒ 7 1/4
