Answer:
Set A's standard deviation is larger than Set B's
Step-by-step explanation:
Standard deviation is a measure of variation. One way to judge the value of standard deviation is by looking at the range of the data. In general, a dataset with a smaller range will have a smaller standard deviation.
The range of data Set A is 25-1 = 24.
The range of data Set B is 18-8 = 10.
Set A's range is larger, so we expect its standard deviation to be larger.

The standard deviation is the root of the mean of the squares of the differences from the mean. In Set A, the differences are ±12, ±11, ±10. In Set B, the differences are ±5, ±3, ±1. We don't actually need to compute the RMS difference to see that it is larger for Set A.
Set A's standard deviation is larger than Set B's.
Answer:
0.0791
Step-by-step explanation:
Given that the probability of white eyes is 1/4 and the probability of red eyes is 3/4, for an individual fly.
Observations are independent
Let A be finding the white eyed fly and B
finding the red eyed fly
P(A) for any random trial= 0.25 and
P(B) = 0.75
Each trial is independent of the other
The probability that at least four flies have to be checked for eye color to observe a white-eyed fly
=Probability for I, II, III and Iv flies to have red eyes * Prob for 5th fly to have white eye
=
I think for this one, B seems the most right :)
B, because thats 50 grams either direction of the given weight.
Answer:
(2xr) x 5
Step-by-step explanation:
Whatever r is you multiply 2 by that then you multiply whatever 2xr is by 5. Another question is that is there a sign between the (2r) and the 5? If not then ignore the sentence before.
