Step-by-step explanation:
Hey there!!
Given equation :
f ( x ) = x² + 2x + 1
Find f ( 2b )
In order to solve this question, we will need to replace the value 2b instead of x
... f(2b) = ( 2b )² + 2 ( 2b ) + 1
... f(2b)= 8b² + 4b + 1
Hope my answer helps!

Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get

Rounding, we get x = 16.35 as our answer
