From 86 books to 150 books

Mademuasel [1]

150 books-86 books= 64 books.

We originally have 86 books, so the percent of increase is:
64 books/ 86 books* 100%= 74.42%

The percent of increase is 74.42%~

Is this answer correct?

Answer:

Step-by-step explanation:

How to solve :

(a-4)/(a^2+8a+12)*(a^2-2a-48)/(a^2+4a-32)

Factor:

a^2+8a+12 = (a+6)(a+2)

a^2-2a-48 = (a-8)(a+6)

a^2+4a-32 = (a+8)(a-4)

simplify a+6, and a-4

you are left with (a-8)/(a+2)(a+8) = (a-8)/(a^2+10x+16)

Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke

In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

A = a person has cancer

B = a person carries the marker.

Given:

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event X provided that another event Y has already occurred is:

$P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}$

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

$P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725$

Thus, the probability that a person with the marker develops cancer is 0.0725.
