Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have

Sample size : n= 35
Let
be the sample mean.
Now ,

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
The answer is -7/8 the alternative answer is 0.875
Answer:
55, 125 and 125
Step-by-step explanation:
In this question, we are asked to find the other 3 angles in an intersection.
Please check attachment for what the diagram of the intersection might look like.
The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.
since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]
These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.
400 miles -----------4 hours
X miles ------------2 hours
4x=400.2
4x=800
X=200
Or
400miles --------------- 4hours
X miles --------------- 6 hours
4x=400.6
4x=2.400
X= 600
Answer:
24
Step-by-step explanation:
The sample space is the total possible values of an experiment or research. Since the total number of hours is 24, then the total possible number (or the limit she can use have) is 24. This she cannot exceed this 24 hour limit. Then we call this the total possible outcome and thus the sample space.
