What is the slope of a line that is perpendicular to the lien whose equation is 2y=3x-1

-2/3

Step-by-step explanation:

We are to find the slope of a line which is perpendicular of a line with an equation .

We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.

So writing the given equation of a line in the slope intercept form:

--->

Here the slope of this line is so the slope of a line which is perpendicular to the given line will be .

answer: 193

explanation:

200-7 = 193

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.
