If the slope of one line is 13/8 what is the slope of the line that is perpendicular to it ?

Step-by-step explanation:

To find the slope of the line that is perpendicular to a line with a given slope, we simply take the negative reciprocal of the given slope.

The given slope is:

The reciprocal is obtained by swapping the numerator and the denominator.

The negative reciprocal of the slope is:

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.
