What is the solution or solutions of 2^x=7

A stock was priced at $12 3/8 per share. It rose in price by $3 1/4 per share. What was its new price?

Option A

The new price is $ $15 \frac{5}{8}$

<h3><u>Solution:</u></h3>

Given that, a stock was priced at $ $12 \frac{3}{8}$ per share.

It rose in price by $ $3 \frac{1}{4}$ per share.

New price = old price + rise in price

Thus to find out the new price, we have to add old price and rise in price

$\text { So, new price }=\$ 12 \frac{3}{8}+\$ 3 \frac{1}{4}$

$\text { New price }=\frac{12 \times 8+3}{8}+\frac{3 \times 4+1}{4}$

On solving we get,

$\text { New price }=\frac{96+3}{8}+\frac{12+1}{4}$

$\begin{array}{l}{\text { New price }=\frac{99}{8}+\frac{13}{4}=\frac{99+26}{8}} \\\\ {\text { New price }=\frac{125}{8}}\end{array}$

On converting to mixed fraction,

$\begin{array}{l}{\text { New price }=\frac{120+5}{8}} \\\\ {\text { New price }=15 \frac{5}{8}}\end{array}$

Hence, the new price is $15 \frac{5}{8}$ , so option A is correct.

If the critic rates a total of 100 restaurants what is the best prediction for the number of restaurants she gives exactly 3 sta

Katarina [22]

Answer:

Probability = 1 / 5

Step-by-step explanation:

Assuming that rates are from 1 to 5 ; with equal probability of being 1, 2 , 3 , 4, 5 each.

So, probability of 3 stars = Outcomes with 3 stars / Total outcomes

= 1 / 5

How am I supposed to figure this out if csc Theta(0) has a radical number on the top?

Harman [31]

$\bf csc(\theta)=\cfrac{hypotenuse}{opposite}\implies csc(\theta)=\cfrac{\sqrt{7}}{2}\cfrac{\leftarrow hypotenuse=c}{\leftarrow opposite=b}\\\\
-----------------------------\\\\
\textit{so hmm using the pythagorean theorem, we can say that}\\\\
c^2=a^2+b^2\implies \pm \sqrt{c^2-b^2}=a\qquad 
\begin{cases}
c=hypotenuse\\
b=opposite\\
a=adjacent
\end{cases}\\\\
\textit{we'll assume is the + of the root, since you're not}\\
\textit{given further info on it, that means the I quadrant}\\\\
$

$\bf -----------------------------\\\\
cos(\theta)=\cfrac{a}{c}\qquad sec(\theta)=\cfrac{c}{a}\qquad tan(\theta)=\cfrac{b}{a}\qquad cot(\theta)\cfrac{a}{b}
$

so just find the "adjacent" side, using the pythagorean theorem, and even though the square root can give you +/-, use the positive one, assuming the angle is in the 1st quadrant

keeping in mind, that the 2nd quadrant is feasible as well, since the opposite side of +2 can also be in the 2nd quadrant

but anyhow, use the I quadrant
