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).
Answer:
b=44
b=44 - 9
b=44 + 5
x+x+x = 44
x + (x-9) + (x+5) = 44
3x - 4 = 44
+4
3x =48
÷3
x=16
So, first photo contains 16 birds.
x=16
(x-9) - - > 16-9 = 7
(x+5) - - >16+5=21
16 + 7 + 21 =44
Answer is 16 birds in first photo
Hope this helps!
Step-by-step explanation:
y=2.5| ?
x=0.5| 20
It'll be criss-crossed then it'll be:-
2.5×20=50
Answer:
144 ft^2
Step-by-step explanation:
property of 45-45-90 triangle: side lengths are 12rt2
12rt2*12rt2/2=144
If you look at the graph you can tell the graph is increasing before x = -2.
From x = -2 to x = 0, it's decreasing.
Then it's increasing again from x = 0 to x = 2, then decreasing after x = 2
So answer is the last one
It is increasing before x = -2 and from x = 0 to x = 2
