3/2 n = 1 . Solve for n.

n=4/2

Step-by-step explanation:

n=3/2+1

n=4/2

The value of n is 2/3

Step-by-step explanation:

3/2 n = 1

3n/2 = 1

Multiply Both side by 2 we get,

3n × 2/2 = 1 × 2

3n = 2

Now, Divide both side by 3 we get,

3n/3 = 2/3

n = 2/3

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.
