Two students each write a function, C(n), that they think can be used to find the number of circles needed to make the nth figure in the pattern shown. Use the drop-down menus to explain why each function does or does not represent the number of circles needed to make the nth figure in the pattern.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
