Since there's a common denominator, you can go straight into subtracting,

so for the top, x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x

A random sample of 133 people was taken from a very large population. Sixty-five of the people in the sample were females.The st

rjkz [21]

Answer: 0.0433

Step-by-step explanation:

Given: Sample size : n= 133

The number of females in sample = 65

Then the proportion of females : $P=\dfrac{65}{133}$

The formula to calculate the standard error of the proportion is given by :-

$S.E.=\sqrt{\dfrac{P(1-P)}{n}}$

$\Rightarrow S.E.=\sqrt{\dfrac{\dfrac{65}{133}(1-\dfrac{65}{133})}{133}}\\\\\Rightarrow\ \Rightarrow S.E.=0.0433444676341\approx0.0433$

Hence, the standard error of the proportion of females is 0.0433.

Sean multiplied two numbers and the resulting product was an irrational number. If the first number was 7/3, which of the follow

lesya692 [45]

Answer: 2*pi and √3.

Step-by-step explanation:

We know that when we multiply a rational number different than zero and an irrational number, the product will be also an irrational number.

Then if one of the numbers for this case is 7/3 (A rational number), the other must be an irrational number.

The given options are:

3/7 (is a rational number, so this is not the correct option)

2*pi (pi is an irrational number, then 2*pi is also an irrational number)

Then (2*pi)*3/7 will be an irrational number.

1 (this is a rational number, then this is not the correct option)

√3 (This is an irrational number, then this will be a correct option)

Then the two correct options are:

2*pi and √3.

the yearly deductible for john's health care decreased from $1250 to $1000. What is the percent decreased?

Dvinal [7]

so, it went down from 1250 to 1000, namely 1250 - 1000 = 250.

now, if we take 1250 to be the 100%, what is 250 off of it in percentage?

$\bf \begin{array}{ccll}amount&\%\\\cline{1-2}1250&100\\250&x\end{array}\implies \cfrac{1250}{250}=\cfrac{100}{x}\implies 5=\cfrac{100}{x}\implies x=\cfrac{100}{5}\implies x=20$
