F(x) = 2/x, g(x) = |x| -1 what is the domain of (fog) (x)? WILL MARK BRAINLIEST

DIA [1.3K]

Answer:

x≠-1,1

Step-by-step explanation:

f(g(x)) is a composition where g(x) is is substituted for x in f(x).

Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.

|x|-1=0

|x|=1

x=1,-1

The probability that a student at certain high school likes art is 36%. The probability that a student who likes art also likes

KIM [24]

Answer: Probability that a student chosen at random likes science given that he or she likes art is 58%

Step-by-step explanation:

Since we have given that

Probability that a student who likes art and science = 21%

Probability that a student who likes art = 36%

According to question,

we need to find the probability that a student chosen at random likes science given that he or she likes art.

So, we will use "Conditional Probability":

P(A) = 0.36

P(S ∩ A) = 0.21

$P(S\mid A)=\frac{P(S\cap A)}{P(A)}\\\\P(S\mid A)=\frac{0.21}{0.36}\\\\P(S\mid A)=0.58\\\\P(S\mid A)=58\%$

Hence, Probability that a student chosen at random likes science given that he or she likes art is 58%.

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - a coordinates of the center

r - a radius

A diameter d = 2r

We have

$x^2+(y-2)^2=100\to r^2=100\to r=\sqrt{100}\to r=10$

Answer: d = 2 · 10 = 20
