On a coordinate plane, 2 dashed straight lines are shown. the first line has a positive slope and goes through (negative 1, 0) and (0, 1). everything to the right of the line is shaded. the second line has a positive slope and goes through (0, negative 2) and (2, 0). everything to the left of the line is shaded. which system of linear inequalities is represented by the graph? y > x – 2 and y < x + 1 y < x – 2 and y > x + 1 y < x – 2 and y > x + 1 y > x – 2 and y < x + 1

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

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.
