Step-by-step explanation:
Given the explicit formula : an = 
find the first three
terms
n = 1 => a(1) = 
= 
n = 2 => a(2) = 
n= 3 => a(3) = 
Hope it will find you well.
50 times 12 equals 600 minus 520 equals 80 bars left over.
Step-by-step explanation:
z-score is:
z = (x − μ) / σ
For the four students:
z = (1990 − 1548) / 319 = 1.39
z = (1280 − 1548) / 319 = -0.84
z = (2240 − 1548) / 319 = 2.17
z = (1450 − 1548) / 319 = -0.31
z-scores are considered significant if they are less than -2 or greater than 2. So the third student's score is unusual.

They obviously didn't get the family membership pass.
Let c be the number of children, a be the number of adults
5c+30a=185
c+a=12 =>c=12-a
5(12-a)+30a=185
60-5a+30a=185
25a=125
a=5
c=12-5=7
there are 7 children and 5 adults.
