Refer to the diagram shown below.
Assume that approximately all the data is contained under the probability distribution curve within 3 standard deviations from the mean. It is actually 99.7%.
Therefore,
bin #1 corresponds to μ-3σ,
bin #11 corresponds to μ,
bin #21 corresponds to μ + 3σ.
Let x be the random variable for bin 17.
Then by interpolation,
The z-score for x is
The probability corresponding to bin #17 is (from standard tables)
P(z≤1.8) = 0.964
Therefore if there are 1000 balls, the sum of the balls in bins 1 to 17 is
0.964 * 1000 = 96.4 ≠ 96 balls.
Answer: 96 balls
Answer:
7.75
Step-by-step explanation:
I divided it and got the answer as 7.75
Answer:
440 m
Step-by-step explanation:
We are to assume that Time is measured from the beginning of Amir's drive. So the altitude at the beginning of Amir's drive is the altitude corresponding to Time = 0. That is the point at the left side of the graph where the blue line meets the vertical axis.
The number on the vertical axis at that point is 440, and the label tells us that is meters of altitude. Amir's altitude at the beginning of his drive is 440 meters.
I think its x-5. I think it is i'm not sure tho
When I was 6 years old my sister was 3 years old.
So, when I am 60 my sister will be, 35
