notka56 [123]

Answer:

A. x ≤ $-\frac{19}{13}$

Step-by-step explanation:

-9x + 2 > 18 or 13x + 15 ≤ -4

-9x > 16 or 13x ≤ -19

x > $-\frac{16}{9}$ or x ≤ $-\frac{19}{13}$

From the choices given, only x ≤ $-\frac{19}{13}$ proves to be correct answer.

For safety reasons, 3 different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills

r-ruslan [8.4K]

Answer:

0.998272 (0.998 in 3sf)

Step-by-step explanation:

Probability(detects) = 0.88

Probability(doesn't detect) = 1 - 0.88 = 0.12

Total probability is always 1

Probability of atleast one detecting = 1 - probability(all not detecting)

= 1 - (0.12×0.12×0.12)

= 1 - 0.001728

= 0.998272

Evaluate : 5-3(x-1) when x=7

Andrei [34K]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{ - 13}}}}$ </h3>

Step-by-step explanation:

Given , x = 7

let's find :

$\sf{5 - 3(x - 1)}$

Plug the value of x

⇒ $\sf{5 - 3(7 - 1)}$

Subtract 1 from 7

⇒ $\sf{5 - 3 \times 6}$

Multiply the numbers

⇒ $\sf{5 - 18}$

Calculate

⇒ $\sf{ - 13}$

Hope I helped!

Best regards!!
