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

Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.

A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))

The equation is in slope-intercept form.

The standard equation of slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept

So, comparing the given equation with the standard equation the y-intercept is -3

y-intercept of y=4x-3 is -3
