All 3 of these would result in the same answer. You can see this by looking at the cross products that would be created for each of them.

In each proportion, you would get a variation of 37 times 7 = 4 times x, when you multiply the numerator of the first by the denominator of the second and the denominator of the first by the numerator of the second.

Answer:

Each proportion is written so the units are in the corresponding positions. The cross products of all the proportions result in the equation 4x = 252, which results in x = 63.

The profit function p(x) of a tour operator is modeled by p(x) = −2x^2 + 700x − 10000, where x is the average number of tours he

pav-90 [236]

Answer:

Range of the average number of tours is between 150 and 200 including 150 and 200.

Step-by-step explanation:

Given:

The profit function is modeled as:

$p(x)=-2x^2+700x-10000$

The profit is at least $50,000.

So, as per question:

$p(x)\geq50000\\-2x^2 + 700x-10000\geq 50000\\-2x^2+700x-10000-50000\geq 0\\-2x^2+700x-60000\geq 0\\\\\textrm{Dividing by 2 on both sides, we get}\\\\-x^2+350x-30000\geq 0$

Now, rewriting the above inequality in terms of its factors, we get:

$-1(x-150)(x-200)\geq 0\\(x-150)(x-200)\leq 0$

Now,

$x0\\x>200,(x-150)(x-200)>0\\For\ 150\leq x\leq200,(x-150)(x-200)\leq 0\\\therefore x=[150,200]$

Therefore, the range of the average number of tours he must arrange per day to earn a monthly profit of at least $50,000 is between 150 and 200 including 150 and 200.
