Which inequality correctly compares Five-sixths, One-half, Three-ninths, and 1?

enot [183]

Answer:

Three-ninths < One-half < Five-sixths < 1

Step-by-step explanation:

We are supposed to compares Five-sixths, One-half, Three-ninths, and 1

$\frac{5}{6} , \frac{1}{2},\frac{3}{9} , 1$

Take LCM of denominators

LCM of 6,9,2,1 = 18

$\frac{5}{6} \times \frac{3}{3}=\frac{15}{18}$

$\frac{1}{2} \times \frac{9}{9}=\frac{9}{18}$

$\frac{3}{9} \times \frac{2}{2}=\frac{6}{18}$

$1 \times \frac{18}{18} = \frac{18}{18}$

$\frac{6}{18}$

$\frac{3}{9}$

Three-ninths < One-half < Five-sixths < 1

For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hi

larisa [96]

Answer: a) $(0.99)^4$

Step-by-step explanation:

Given : For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills bank.

Each of the four systems detects theft with a probability of .99 independently of the others .

Probability for independent events $(E_1 , E_2 , E_3 , ....., E_n)$ occurs together = $P(E_1)\times P(E_2)\times P(E_3)\ .....\times P(E_n)$ .

Then, the probability that when a theft occurs, all four systems will detect it

= (0.99) x (0.99) x (0.99) x (0.99)

$= (0.99)^4$

Hence, the probability that when a theft occurs, all four systems will detect it is $(0.99)^4$ .

Hence, the correct answer is a) $(0.99)^4$ .
