Answer:
a) 0.226
b) 0.613
c) Part(a)
d) Unusual event
Step-by-step explanation:
We are given the following in the question:
x: 0 1 2 3 4 5 6 7 8
P(x): 0.000 0.003 0.016 0.054 0.121 0.193 0.226 0.193 0.121
x: 9 10 11 12
P(x): 0.054 0.016 0.003 0.000
a) Probability of exactly 6 Mexican-Americans among 12 jurors.
![P(x = 6) = 0.226](https://tex.z-dn.net/?f=P%28x%20%3D%206%29%20%3D%200.226)
Thus, 0.226 is the probability of exactly 6 Mexican-Americans among 12 jurors
b) Probability of 6 or fewer Mexican-Americans among 12 jurors
![P(x \leq 6) \\=P(x = 0) + P(x = 1) + P(x =2) + P(x = 3) + P(x = 4) + P(x = 5) + P(x = 6)\\= 0.000+0.003+ 0.016 +0.054 +0.121+ 0.193+ 0.226\\=0.613](https://tex.z-dn.net/?f=P%28x%20%5Cleq%206%29%20%5C%5C%3DP%28x%20%3D%200%29%20%2B%20P%28x%20%3D%201%29%20%2B%20P%28x%20%3D2%29%20%2B%20P%28x%20%3D%203%29%20%2B%20P%28x%20%3D%204%29%20%2B%20P%28x%20%3D%205%29%20%2B%20P%28x%20%3D%206%29%5C%5C%3D%200.000%2B0.003%2B%200.016%20%2B0.054%20%2B0.121%2B%200.193%2B%200.226%5C%5C%3D0.613)
Thus, 0.613 is the probability that 6 or fewer Mexican-Americans among 12 jurors.
c) The result from part (a), because it measures the probability of exactly 6
successes.
d) Unusual event
An event is said to be unusual if the probability of event is less than 0.5.
Since
![P(x = 6) = 0.226 < 0.5](https://tex.z-dn.net/?f=P%28x%20%3D%206%29%20%3D%200.226%20%3C%200.5)
Thus, it is an unusual event as the probability is less than 0.5
Answer:
9 servings of meat.
Step-by-step explanation:
The first ratio you are given is 8:36. You are trying to figure out what 2:__ is.
8/36 x 2/X
Multiply 2 x 36 and get 72. Now divide 72 by 8 to get 9.
Answer:
(3, -2)
Step-by-step explanation:
after flipping the triangle over the y axis the new point A would be at (1,1)
then following the translation the point would move right twice and down twice leaving the new point A at (3, -2)
Answer:
The Largest Number is 27.
Step-by-step explanation:
Range = Largest Number - Smallest Number
18 = Largest Number - 9
Rearrange the formula to find the Largest Number:
Largest Number = Range + Smallest Number
Largest Number = 18 + 9
Largest Number = 27
You can check this by putting it into the original formula:
Range = Largest Number - Smallest Number
18 = 27 - 9
