Answer:

The ordered pair is (1, 2) ⇒ A

Step-by-step explanation:

In the function f(x) = y

x is the domain of the function

y is the range of the function

The domain is all the x-coordinates of the points lie on the graph of the function

The range is all the y-coordinates of the points lie on the graph of the function

That means any ordered pair (x, y) satisfy the function f(x) = y, lies on the graph of the function

∵ f(x) = 2x

→ That means y = 2x

∵ x = 1

→ Substitute the value of x in the function above

∴ f(1) = 2(1)

∴ f(1) = 2

→ That means at x = 1, y = 2

∴ The ordered pair is (1, 2)

Integral sqrt(4+3x) dx

Alisiya [41]

Let 4 + 3x = u

then 3dx = du

or, 1/3∫u√du

= 1/3u^3/2/(3/2)

= 2/9∗(4+3x)^3/2

Ymorist [56]

Answer:

52.5% probability that A occurs given B occurs

Step-by-step explanation:

Suppose we have two events, A and B, the conditional probability formula is:

$P(A|B) = \frac{P(A \cap B)}{P(B)}$
