The length of a postage stamp is 4 1/4 mm longer than its width. The perimeter of the stamp is 124 1/2 mm. Write an equation that represents the perimeter in terms of its width w. What is the width of the postage stamp? What is the length of the postage stamp. A. 2w + 2 (w + 4 1/4) = 124 1/2
B. 2w + (2w * 124 1/2) = 4 1/4
C. w (w + 4 1/4) = 124 1/2
D. 2w - 2 (w + 4 1/4) = 124 1/2

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.
