Answer:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
Step-by-step explanation:
For this case we want to find the following probability:

And for this case we can use the normal standard distribution and the complement rule and we have this:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
Differentiation is part of calculus
differentiation basically allows you to find the gradient of tangent
Answer:
475.
Step-by-step explanation:
We have been given that for a normal distribution with μ=500 and σ=100. We are asked to find the minimum score that is necessary to be in the top 60% of the distribution.
We will use z-score formula and normal distribution table to solve our given problem.

Top 60% means greater than 40%.
Let us find z-score corresponding to normal score to 40% or 0.40.
Using normal distribution table, we got a z-score of
.
Upon substituting our given values in z-score formula, we will get:





Therefore, the minimum score necessary to be in the top 60% of the distribution is 475.
