Answer:
Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.
Step-by-step explanation:
Difference between hypergeometric and binomial distributions:
In the hypergeometric distribution, trials are dependent of other trials, while in the binomial distribution, they are independent. This can be examplified that in the hypergeometric distribution, the candidates are chosen from a set without replacement, while in the binomial distribution they are chosen with replacement.
In this question:
Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.
Answer:
The number of coins to make 6440 mm diameter is 230
Step-by-step explanation:
The diameter of the coin is 28mm
Number of coins to have 6440 mm will be
6440/28
= 230
Let's put it in slope intercept form
2y = x - 14
y = (1/2) x - 7
[ ] Slope = 2. Nope, slope=1/2
[ ] y intercept = 7. Nope, y intercept = -7
[ ] line moves up from left to right. Positive slope, that's TRUE
[ ] x intercept is positive.
The x intercept is the x value when y=0, so is 14. This is TRUE
Answer: third & fourth
Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down
103 chairs
Answer: A
Step-by-step explanation: Subtract then divide.
