Answer: 84.13%
Step-by-step explanation:
Given : The scores in a a language test with normally distributed.
Mean : 
Standard deviation: 
Let x be the random variable that represents the scores of students.
Formula for z-score: 
For x= 60 , we have
The probability f test takers scored a 60 or above :-
Hence, the percentage of test takers scored a 60 or above = 84.13%
Answer: X= -8
1) Move all X’s to left side by subtracting 14x from both sides.
Leaves you with -3x=24.
2) -3x=24 is the same as 3x= -24
3) Divide both sides by 3 to get X= -8

Answer:
31st term = 84
Step-by-step explanation:
Given:
204, 200,196,...
Find:
31st term
Computation:
204, 200,196,...
First term a = 204
Difference d = a3 - a2
Difference d = 196 - 200
Difference d = -4
An = a + (n-1)d
A31 = 204 + (31-1)(-4)
A31 = 204 - 120
A31 = 84
