Use the definitions listed in section 6.1.2 with f(x, y, z) = x2 + yz, f(x, y, z) = xy, yz, xz , and g(x, y, z) = −sin(z), exz, y . compute the vector (f(f + , 1, 3). (your instructors prefer angle bracket notation < > for vectors.)

the aswere is the one with all 8's and the second one is with the 10,8 and 6

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.
