saw5 [17]

Answer:

We conclude that the 8 % of calls result in a sale.

We conclude that the 5.3% of sales are made to women.

Step-by-step explanation:

We know that 70% of calls arc not completed (the party does not answer or refuses to talk), that 20% result in talking to a woman, and that 10% result in talking to a man. After that point, 30% of the women and 20% of the men actually buy something.

We calculate what percentage of calls result in a sale, and we get:

$p=\frac{20}{100}\cdot \frac{30}{100}+\frac{10}{100}\cdot \frac{20}{100}\\\\p=\frac{6}{100}+\frac{2}{100}\\\\p=\frac{8}{100}$

We conclude that the 8 % of calls result in a sale.

We know that the ratio of women to men talking on the telephone is 2:1.

We calculate a percent of sales are made to women, and we get:

$w=\frac{2}{3}\cdot 8\\\\w=\frac{16}{3}\\\\w=5.3$

We conclude that the 5.3% of sales are made to women.

If x/y = -3, then find x²/y² + y²/x².

sladkih [1.3K]

Answer:

9.11

Step-by-step explanation:

Given that,

$\dfrac{x}{y}=-3$

We need to find the value of $\dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}$

The value of $\dfrac{y}{x}=\dfrac{-1}{3}$

So,

$\dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}=(\dfrac{x}{y})^2+(\dfrac{y}{x})^2\\\\=(-3)^2+(\dfrac{-1}{3})^2\\\\=9+\dfrac{1}{9}\\\\=9.11$

So, the required answer is equal to 9.11.
