2, 3, and 4
Step-by-step explanation:
2) Information carried by digital communication can be stored as digital information on electronic media such that they can be accessed with the aid of electronics and can be stored in a wide variety of recording formats including magnetic and optical media
3) Digital communication can be made over very long distance using serial communication. Fiber optics cables are used for transmitting information across continents using square waves which is a digital signal
4) Digital signals are less likely to be subjected to interference, distortion, and generation loss which is prone to analog signals, and therefore, there is less chance of signal loss when using digital communication.
-4
8/2 = 4
A negative times a positive is negative so it’s
-4
To find f(-7), just plug -7 in for all x
2(-7) + 8
-14 + 8
-6 is the answer!
Answer:
We can break this down:
The student has a one out of five chance of getting a correct answer, and a four out of five chance of an incorrect answer. We can express the students odds of getting one incorrect answer as 4/5. In order to get the odds of two wrong answers, we need to multiply this answer again by the odds of choosing a wrong answer. Therefore:
The odds of one wrong answer = 4/5
The odds of two wrong answers = (4/5) * (4/5) = 16/25 chance of getting both of the questions wrong.
