Answer:

Step-by-step explanation:

It is mandatory (required) to use " ^ " for exponentiation:

(3x – 5)^2 = 4

Taking the square root of both sides, we get

3x - 5 = ±2, or

3x = 5 ±2, or

(a) 3x = 7 => x = 7/3, and

(b) 3x = 3, or x = 1

A certain university has 18 vehicles available for use by faculty and staff. Five of these are vans and 13 are cars. On a partic

Reil [10]

Answer:

$P(E) = 0.278$

$P(F |E) = 0.2353$

$P(E and F) = 0.0654$

Step-by-step explanation:

The number of vehicles available is $N = 18$

The number of vans is k = 5

The number of cars is n = 13

Generally P(E) is mathematically represented as

$P(E) = \frac{k}{N}$

=> $P(E) = \frac{5}{18}$

=> $P(E) = 0.278$

Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as

$P(F |E) = \frac{5 -1}{18-1}$

$P(F |E) = \frac{4}{17}$

$P(F |E) = 0.2353$

Generally $P(F | E)$ is also mathematically represented as

$P(F | E) = \frac{P(E and F)}{P(E)}$

=> $P(E and F) =P(E) * P(F | E)$

=> $P(E and F) = 0.278 * 0.2353$

=> $P(E and F) = 0.0654$
