A communication channel transmits the digits 0 and 1. Due to static, sometimes a digit will be incorrectly switched, with probability 0.2. To re-duce the chance of a miscommunication, we will transmit our important yesor no message redundantly: by sending 00000 instead of 0 or 11111 insteadof 1. Then it will be decoded by majority on the receiving end (i. e. 11101 isinterpreted as 1). What is the probability this still results in a miscommuni-cation

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
