Plz ! the table shows the number of candies packed by machine j. the equation shows the number of candies packed by machine k. in both representations, x is a measure of the number of minutes and y is a measure of the number of candies packed.
machine j candy packing
x (minutes) y (candies)
3 90
6 180
9 270
12 360

machine k: y=26x

how many more candies could machine j pack than machine k in 11 minutes

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.
