One of the ekati mine’s pipes, called the panda pipe, has northern and southern gates. a communications tower stands 100 m outside the north gate. the tower can be seen from a point 300 m east of the south gate at camp a. a) the distance between camp a and camp b is 600 m. calculate the diameter of the panda pipe. b) calculate the distance from camp b to the tower.

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.
