Rob owns 1/8 of the stock in a local bread company. His sister Talia owns half as much stock as Rob. What part of the stock is o

Nana76 [90]

Answer:

$\frac{13}{16}$

Step-by-step explanation:

1/2 of 1/8 is the same thing as 1/2*1/8.

So multiply it out:

$\frac{1}{2}*\frac{1}{8}=\frac{1}{16}$ This is the amount of stock that Talia uses.

Now covert:

$\frac{1}{8}=\frac{2}{16}$ This is how much Rob owns.

Now add:

$\frac{2}{16}+\frac{1}{16}=\frac{3}{16}$

Since you cannot simplify, the answer would be

$\frac{3}{16}$ .

Now subtract $\frac{3}{16}$ from the possible value.

$\frac{16}{16} -\frac{3}{16}$ and you get $\frac{13}{16}$ . This is the portion that they both don't share.

Hope it Helps!

Solving for a Confidence Interval: Algebra 2 points possible (graded) In the problems on this page, we will continue building th

baherus [9]

Answer:

Step-by-step explanation:

1) The given inequality is

$|\sqrt{n} \frac{(\bar R_n-p)}{\sqrt{p(1-p)} } |$

$\to n( \bar R _n - p)^2$

$\to n\bar R +np^2-2nR_np$

Arranging the terms with p² and p, we get

$p^2(n+q^2_{\alpha /2)-p(2n \bar R _n+q^2_{\alpha / 2})+n \bar R ^2 _n$

Hence, the inequality is of the form

Ap² + Bp + c < 0

2. A quadratic equation of the form

Ap² + Bp + c < 0 with A > 0 looks like
