Acertain polygon has its certifies at the following points: (2, 5), (4, 7), (7, 7), and (9, 5). what is the best description of this polygon

answer:

step-by-step explanation:

given that when x denotes the errors in an experimental transmission channel, when checked by a certifier that detects missing pulses. follows the cumulative density function as given below:

errors in an experimental transmission channel are found when the transmission is checked by a certifier that detects missing pulses.the number of errors found in a eight-bit byte is a random variable with the following distribution:

f(x) = { 0 x< 1

0.7 1 < = x < 4

0.9 4 < = x < 7

1 7 < = x

determine each of the following probabilities:

(a) p(x < = 4) (b) p(x > 7)

(c) p(x < = 5) (d) p(x > 4)

(e) p(x < = 2)

answer:

the best description would either be (2,5) or (4,7). but i am sure that it would be (4,7) because a polygon needs to be at a plot line of 3 away.

the answer is 62.8 cubic units
