How do you rewrite an equation by completing the square?<br> x^2+10x+21=0

AleksAgata [21]

Answer:

Step-by-step explanation:

x²+10x+21=0

x²+10x+(10/2)²-(10/2)²+21=0

x²+10x+25-25+21=0

(x+5)²-4=0

(x+5)²=4

(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²

(x+y)²=x²+2xy+y²

coefficient of x=2y

y²=[(coefficient of x)/2]²=(2y/2)²=y²

What is 33.61111111 in fraction form

madreJ [45]

The correct answer is: " $\frac{33,611}{1,000}$ " .

____________________

<u>Step-by-step explanation</u>:

Based on the assumption that the "1" repeats infinitely; in the given value:

" 33.61111111 ...." ;

_______

Note that the "611" ; after the decimal point; this goes to the "thousandths";

place (is "3 (three) digits long.").

_______

As such; we rewrite the number as:

_______

" $\frac{33.611}{1}$ " ;

and we multiply BOTH the "numerator" And the "denominator" by: "1000" :

_______

→ " $\frac{(33.611)*(1000)}{(1)*(1000)}$ " ;

to get:

→ " $\frac{33611}{1000}$ " ; → which cannot be reduced any further.

_______

The correct answer is: " $\frac{33,611}{1,000}$ " .

_______

Hope this is helpful to you!

If y has moment-generating function m(t) = e 6(e t −1) , what is p(|y − µ| ≤ 2σ)?

Lostsunrise [7]

Since $\mathrm M_Y(t)=e^{6(e^t-1}$ , we know that $Y$ follows a Poisson distribution with parameter $\lambda=6$ .

Now assuming $\mu,\sigma$ denote the mean and standard deviation of $Y$ , respectively, then we know right away that $\mu=6$ and $\sigma=\sqrt6$ .

So,

$\mathbb P(|Y-\mu|\le2\sigma)=\mathbb P(6-2\sqrt6\le Y\le6+2\sqrt6)=\dfrac{66366}{175e^6}\approx0.940028$
