What is the simplified form of the quantity y−squared minus y minus 12 over the quantity y−squared minus 2y minus 15?

makvit [3.9K]

(y^2-y-12)/(y^2-2y-15) factor both the numerator and denominator...

(y^2-4y+3y-12)/(y^2-5y+3y-15)

(y(y-4)+3(y-4))/(y(y-5)+3(y-5))

((y-4)(y+3))/((y-5)(y+3)) so the (y+3) terms cancel leaving

(y-4)/(y-5)

Ugo [173]

Answer: 0.0475

Step-by-step explanation:

Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.

Where , Population mean : $\mu=2.5\text{ million}=2.5\times1000000=2500000$

Standard deviation : $\sigma=300000$

To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.

∵ $z=\dfrac{x-\mu}{\sigma}$

Then , for x= 3,000,000

$z=\dfrac{3000000-2500000}{300000}=1.67$

Then , the probability that the firm’s sales will exceed $3 million is given by :-

$P(z>1.67)=1-P(z$

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
