For what values of x is the rational expression below undefined?

EastWind [94]

In order for the rational expression to be undefined, the denominator must be equal to 0.

Thus, set 3(x+5)9(x-5)=0

x=5 and -5

PLZZZZ HELPPPPPPPPP!!!! a survey asks teachers and students whether they would like the new school mascot to be a Viking or a Pa

VARVARA [1.3K]

Answer:

Step-by-step explanation:

Two events A and B are called independent, when

$P(B|A)=P(B),$

where $P(B|A)$ is the probability that B occurs given that A has already occurred.

A = randomly selected person is a student

B = randomly selected person prefer "Vikings"

B|A = randomly selected student prefer "Vikings"

Probabilities:

$P(A)=\dfrac{100}{125}=\dfrac{4}{5}=0.8\\ \\P(B|A)=\dfrac{80}{85}=\dfrac{16}{17}\approx 0.94$

Since

$0.80\neq 0.94$

we can state that events are not independent.
