Cho toán tử tuyến tính f: R3 - R3, f (x, y,z) = (2x; -x+y; 11y-z) a) Chứng minh f là một ánh xạ tuyến tính

b) Cho cơ sở B = ( u1(3;2;1), u2(-2;1;2), u3(1;2;-2) ). Tìm ma trận ánh xạ tuyến tính của (f)B

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.
