We want to find the value that makes

To find it we must look at the standard normal table, using the complementary cumulative table we find that

Then, using the z-score we can find the minimum score needed, remember that

Where
σ = standard deviation
μ = mean
And in our example, x = minimum score needed, therefore

Rounding to the nearest integer the minimum score needed is 568, if you get 568 you are at the top 20.1%.
16/1 *4/3
16*4 then divide that answer by 3.
The expression is equivalent to 49/8.
Answer:
2
Step-by-step explanation:
Divide 3.4 by 1.7 and you get 2
Three ways to express it as a product of powers are:
3x3x3x3x3
3^5
243
Hope I helped!
