Answer:
And we can use the following z score:
And replacing we got using the normal standard distribution table or excel:
C.0.8413
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the records of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
We select a sample of size n=36, and we want to calculate this probability:
And we can use the following z score:
And replacing we got using the normal standard distribution table or excel:
C.0.8413
Answer:
your choice is correct
Step-by-step explanation:
The problem statement tells you a point on the graph is (5 million dollars, 40 million computers).
When you look for these numbers, 5 and 40, you find the 5 (million dollars) is on the horizontal axis, and the 40 (million computers) is on the vertical axis. The appropriate labeling should be fairly obvious.
Answer:
g^8
Step-by-step explanation:
The "." means multiplication. Therefore take g as common.
But, for the powers its different.
When constants are being multiplied, the powers will be added together:
g^5 x g^3
=g^ 5+3
=g^8
If the constants were being added then the powers would hv been multiplied: g^5 + g^3
= g^5 x 3
=g^15
Similarly, if the constants were being divided then the powers would hv been substracted: g^5/g^3
=g^5-3
=g^2
And if the constants were being substracted the the powers would hv been divided: g^5 - g^3
=g^5/3
So, therefore ur answer is g^8.
Hope u understood :D
