Identify the missing numbers below to show the result of multiplying the numbers.

(3.5 × 1016)(2.2 × 1010) = a × 10b

a= 7.7
b = 26

A = 7.7 and B = 26

Step-by-step explanation:

Given expression,

According to the question,

By comparing,

A = 7.7

B = 26

0.00111

Step-by-step explanation:

Since the modem receiver takes a majority vote of the five

received bits to estimate the input signal, it will only make a wrong decision if 3, 4 or 5 of the 5 bits received are wrong.

Given that the channel changes an input bit to its complement with probability p =1/10 and it does so independently of its treatment of other input bits, the probability of changing 3 bits out of five is 0.1*0.1*0.1 = 0.001, of changing 4 is 0.0001 and of changing 5 is 0.00001

So, the probability that the modem makes a wrong decision is 0.001+0.0001+0.00001 = 0.00111
