You can perform all kind of operation that are one the inverse of the other, so that the value won't change. For example, you can multiply and divide by 2:
Or add and subtract 5:
Based on the given description above, I have analyzed it and come up with a solution to get the probability if in a random sample of 25 students from this said group and the average height is between 73 and 75 inches. So if you calculate it, it will be like this:
<span>2P(Z<2)−1</span>
To find the probability of Z, use the normal distribution table.
The value for Z being less than 2 is 0.9772.
The final result is then<span><span>2(0.9772)−1=0.9544
Hope this is the answer that you are looking for.</span></span>
Answer:
(7000-4000) will make 4000x100 =
(7000:4000-1)x100 =
175-100 = 75
the percentage increase from 4000 to 7000 by 75%
