A(1, 1)
b (1, 3)
c (4, 3)

rectangle abcd has the coordinates shown.

find the coordinates of point
d.

a) (5, 1)
b) (4, 2)
c) (3, 1)
d) (4, 1)

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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.
