HELP ASAP On this math

x = 2, y = 14

x = 3, y = 10

x = 4, y = 6

x = 5, y = 2

Step-by-step explanation:

y = 22 - 4x

When x = 2,

y = 22 - 4(2)

=> y = 22 - 8

=> y = 14

When x = 3,

y = 22 - 4(3)

=> y = 22 - 12

=> y = 10

When x = 4,

y = 22 - 4(4)

=> y = 22 - 16

=> y = 6

When x = 5,

y = 22 - 4(5)

=> y = 22 - 20

=> y = 2

step-by-step explanation:

just plug in each number for x and see which ones work and don't

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.
