Answer:
x3, +3
Step-by-step explanation:
Each number gets multiplied by 3 and then you add 3.
You are counting by 10s so the answer is 40,50,60,70,80
the complete sequence: 10,20,30,40,50,60,70,80,90,100
Answer: About 191 students scored between a 60 and an 80.
Step-by-step explanation:
Given : A set of 200 test scores are normally distributed with a mean of 70 and a standard deviation of 5.
i.e.
and 
let x be the random variable that denotes the test scores.
Then, the probability that the students scored between a 60 and an 80 :

The number of students scored between a 60 and an 80 = 0.9544 x 200
= 190.88 ≈ 191
Hence , about 191 students scored between a 60 and an 80.
First we will evaluate: ( substitution: u = x² - y², du = - 2 y dy )

=

( than plug in x and 0 )
=

=
= 1/3 x³ ( then another integration )

= 1/3 * 1/4 =
1/12
