Given the equation y − 4 = 3/4(x + 8) in point-slope form, identify the equation of the same line in standard form.
select one:
a. −3/4x + y = 10
b. 3x − 4y = −40
c. y = 3/4x + 12
d. y = 3/4x + 10

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.
