Kevin installed a certain brand of automatic garage door opener that utilizes a transmitter control with five independent​ switc

hes, each one on or off. The receiver​ (wired to the​ door) must be set with the same pattern as the transmitter. If one of​ Kevin's neighbors also has this same brand of​ opener, and both of them set the switches​ randomly, what is the probability that they will use the same​ setting?

Answer:

0.03125

Step-by-step explanation:

Number of Combinations possible with the Transmitters = 2*2*2*2*2 = 32

Probability that they will use the same settings = 1 - Probability of them using different settings.

= 1 - 32*31/(32^2)

=1 - 992/1024

= 1 - 0.96875

= 0.03125

Given:

3b+8\geq 14

To find:

The steps to solving the given inequality.

Solution:

We have,

3b+8\geq 14

Subtract 8 from both sides.

3b+8-8\geq 14-8

3b\geq 6

Divide both sides by 3.

\dfrac{3b}{3}\geq \dfrac{6}{3}

b\geq 2

Two steps are:

1. Subtract 8 from both sides of the inequality.

2. Divide both sides of the inequality by 3.

Therefore, the correct option is A.

The world's heaviest man is reported to have had a mass of 635 kg what was his weight
nataly862011 [7]

Answer:

about 6230 N

Step-by-step explanation:

The mass is given to 3 significant figures, so we need a value for the acceleration due to gravity that is at least 3 significant figures. The standard value is 9.80665 m/s². Using that, the force is ...

... F = ma = (635 kg)(9.80665 m/s²) = 6227.22275 N

Since the mass is only good to 3 significant figures, the force must be rounded to that precision: 6230 N.
