Find the quotient of the complex numbers. leave answer in polar form.

z1 = sqrt(3)(cos 7pi/4 + i sin 7pi/4)
z2 = sqrt(6)(cos 9pi/4 +i+sin 9pi/4)

a. sqrt(2)/2 (cos 3pi/2 - i sin 3pi/2)

b. sqrt(2)/2(cos 3pi/2 - i sin 3pi/2

c. sqrt(2)/2(sin 3pi/2 +i cos 3pi/2)

d. sqrt(2)/2(cos 3pi/2 +i sin 3pi/2)

he has now walked a total of what?

if i know what this is maybe i can

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.
