20% of students take exactly two courses, and 50% of students take one or two courses.

Given that fifty part-time students were asked how many courses they were taking this term, of which 15 take only 1 course, while 10 take 2 courses, to determine what percent of students take exactly two courses, and what percent of students take one or two courses, the following calculation must be performed:

(10/50) x 100 = X 0.2 x 100 = X 20 = X (25/50) x 100 = X 0.5 x 100 = X 50 =X

Therefore, 20% of students take exactly two courses, and 50% of students take one or two courses.

Answer from: alexaguayza6

There are 50 part-time students:

15 of them, take only one course.

10 of them, take only two courses.

then the rest, this is:

50 - 10 - 15 = 25

25 students take 3 courses.

b) What percent of students take exactly two courses?

15 out of 50 take exactly two courses, the percentage is:

p = (10/50)*100% = 20%.

c) What percent of students take one or two courses?

This will be the percentage of students that take only one course plus the percentage of students that take two courses:

The percentage of students that take two courses is already known: 20%.

Now, for 1 course we have 15 students out of 50, the percentage is:

p = (15/50)*100% = 30%.

Then the percentage that take 1 or 2 courses is:

P = 30% + 20% = 50%

Answer from: Quest

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

$m_ {1} * m_ {2} = - 1$

then, given the following line:

$6x-3y = 18\\6x-18 = 3y$

$\frac {6x} {3} - \frac {18} {3} = y\\y = \frac {6x} {3} - \frac {18} {3}\\y = 2x-6$

so, $m_ {1} = 2$

we are looking for m_ {2}:

$m_{2}=\frac{-1}{m_{1}}\\m_{2}=\frac{-1}{2}\\m_{2}=-\frac{1}{2}$

then, the line is given by:

$y = - \frac {1} {2} x + b$

we find "b" replacing the given point:

$8 = - \frac {1} {2} (0) + b\\8 = b$

finally, the equation is:

$y = - \frac {1} {2} x + 8$

option c

Answer from: Quest

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
