Step 1: Define

$\displaystyle \frac{7x^2 + 11x - 6}{7x^2 - 10x + 3}$

Step 2: Simplify

[Fraction] Factor numerator: $\displaystyle \frac{(x + 2)(7x - 3)}{7x^2 - 10x + 3}$
[Fraction] Factor denominator: $\displaystyle \frac{(x + 2)(7x - 3)}{(x - 1)(7x - 3)}$
[Fraction] Divide: $\displaystyle \frac{x + 2}{x - 1}$

The probability according to the given scenario is:

(a) 0.0395

(b) 0.95

(c) 0.076

The given values are:

$P(B/A) = 0.79$
$P(A) = 0.05$

(a)

The probability that the b/w has tuberculosis as well as having (+) test will be:

→ $P(A \cap B) = P(B/A).P(A)$

By substituting the values, we get

→ $= 0.79\times 0.05$

→ $= 0.0395$

(b)

The probability that a person does not have tuberculosis will be:

→ $P(A') = 1-P(A)$

→ $=1-0.05$

→ $= 0.95$

(c)

The person does not have tuberculosis as well as have a (+) test, the probability will be:

→ $P(A' \cap B) = P(A').P(B/A')$

→ $= 0.95\times 0.08$

→ $= 0.076$

Suppose y = 2x + 1 , where x and y are functions of t. (a) if dx/dt = 6, find dy/dt when x = 4. dy dt = (b) if dy/dt = 2, find d

evablogger [386]

$y=2x+1\\\\\dfrac{dy}{dt}=2\dfrac{dx}{dt}$

(a) For dx/dt=6, dy/dt = 2·6 = 12

(b) For dy/dt=2, 2 = 2·dx/dt ⇒ dx/dt = 1

_____

The value of x is irrelevant for this question.

=====

If your function is 2^x +1 or 2^(x +1), it needs to be written as such. The answer above applies to the function given.
