Answer:
No, the given procedure doesn't result in a binomial distribution.
Step-by-step explanation:
We can identify if a given procedure results in binomial distribution by observing whether these four conditions are met or not.
Condition 1: Each observation should be independent, it must not depend on the result of previous observation.
Condition 2: The probability of success should stay same from trial to trial.
Condition 3: n is fixed (the number of observations)
Condition 4: There are only two outcomes success or failure.
Surveying 2828 people to determine which statistics courses they have taken.
Condition 3 is satisfied since n is fixed
Condition 1 is satisfied since each observation is independent
Condition 4 is not satisfied since there can be more than 2 answers from the people (statistics courses can be many).
Responder:
Altura = 26
Base = 20
Explicación paso a paso:
Dado que :
Dejar :
Base = b
Altura = 6 + b
Área del rectángulo = base * altura
520 = b * (6 + b)
520 = 6b * b²
b² + 6b - 520 = 0
b² + 26b - 20b - 520 = 0
segundo (segundo + 26) - 20 (segundo + 26) = 0
b + 26 = 0
b = - 26
b - 20 = 0
b = 20
Ignorar negativo
b = 20
Altura = 20 + 6 = 26

Answer:
17 ft, 27 ft, 20 ft
Step-by-step explanation:
Let s represent the length of the shortest side. The the longest side is (2s-7) and the third side is (s+3). The perimeter is the sum of the side lengths:
64 = s +(2s -7) +(s +3)
64 = 4s -4 . . . . . . . . . . . collect terms
16 = s -1 . . . . . . . . . . divide by 4
17 = s . . . . . . . . . add 1
2s -7 = 2·17 -7 = 27 . . . . . the length of the longest side
s +3 = 17 +3 = 20 . . . . . . . the length of the third side
The side lengths are 17 feet, 27 feet, and 20 feet.
