Answer: 28 points
Step-by-step explanation:
Given : Lexie scores an average of 
points in a pinball game, and her points in a pinball game are normally distributed.
Let x be the random variable that represents the her points in a pinball game.
, where s is the standard deviation.
Lexie scores 471 points in a game, and this value has a z-score of −2.
i.e. 
Hence, the standard deviation= 28 points
20, you have ten pencils but bring ten more count them all.
Okay, this may seem complex for some but its actually is simple!
However, we will have to use double fractions which a lot of people dont like
So we have (8/5)/24 for our units. However, we need to find 2 miles. 8/5 is a bit confusing and hard to represent if we are converting to integers.
But, theres a trick. We need 2 miles so we can actually make 2 = 10/5.
We now have (8/5)/24 = (10/5)/x
Using cross-multiplication, we can solve for x!
Hope this helps
