The correct answer is c. Biased samples are NOT random. If you choose a couple people from <em>each grade </em>therefor the answer is c.
Step-by-step explanation:
1 + - 1 can also be written as 1 - 1.
1 + - 1
= 1 - 1
= 0
Hence proved.
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(4,3)....x1 = 4 and y1 = 3
(1,1)...x2 = 1 and y2 = 1
now we sub
d = sqrt (1 - 4)^2 + (1 - 3)^2
d = sqrt (-3^2) + (-2^2)
d = sqrt (9 + 4)
d = sqrt 13
d = 3.61
Answer:
true for number 1 and for number 2 It is not thats the wrong answer the real answer is 13 because 10 11 12 13
Step-by-step explanation:
Answer:
C: 0.5
Step-by-step explanation:
The probability of any outcome is the long-term relative frequency of that outcome. Probabilities are between zero and one, inclusive (that is, zero and one and all numbers between these values).
