Answer:
The answer is B. The sample was biased because the survey was only given to a select group (the males). An unbiased sample would be a large group of random people (all genders included).
Step-by-step explanation:
cube b side = 2*4=8 cm
cube a volume = 64 cm^3
cube b volume = 512 cm^3
Answer: 0.79 or 79%
Step-by-step explanation:
Given : The probability that the athletes are football players : P(A)=0.33
The probability that the athletes are basketball players: P(B)=0.66
The probability that the athletes play both football and basketball : P(A∩B)=0.20
Now, the probability that the athlete is either a football player or a basketball player is given by :-

Hence, the probability that the athlete is either a football player or a basketball player = 0.79
Or we can write it as 79%.
Answer:
79 m
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + b)
=> 288 = 2(l + 65)
=> 288/2 = l + 65
=> 144 = l + 65
=> 144 - 65 = l
=> 79 = l
Hence,
Length of rectangle is 79 m
