Answer:

The probability that they are the three youngest students is 0.002197.

Step-by-step explanation:

If 3 students are randomly selected from 15 available students, the probability that they are the three youngest students = 1 / 15C3

15C3=\frac{15!}{3!12!}

= 455

= \frac{1}{455}

= 0.002197

Answer:

y= -(1/3)x -r

Step-by-step explanation:

a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.

In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.

The problem states the line has the same y-intercept so it has to still be -r.

So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

The functions f(x) = -1+2 and
xz_007 [3.2K]

The graph of f(x) is given. And equation of g(x)= -f(x+2)

f(x+2) means f(x) will move 2 units left. And the negative in front means reflection on x axis.
