A random variable can be either discrete or continuous. It is discrete it can assume only a finite number of values, or a countable infinity of values at most.
It is continuous if it can assume values in an interval, or in general, an uncountable infinity of values.
That being said, we have:
Option A is a discrete random variable, because the number of heads in 5 throws can be 0, 1, 2, 3, 4 or 5. So, we have finitely many possible values.
Option B is a discrete random variable, because the number you roll on a die is either1, 2, 3, 4, 5 or 6. So, we have finitely many possible values.
Option C is a discrete random variable, because if there are n students in a class, the number of boys is an integer between 0 and n. So, we have finitely many possible values.
Option D is finally a continuous random variable, because the height of a 10-year-old can be any number (in a suitable range of course).
Answer:
x = (cy+b)/a
Step-by-step explanation:
ax-b=cy
Add b to each side
ax-b+b=cy+b
ax = cy +b
Divide each side by a
ax/a = (cy+b)/a
x = (cy+b)/a
Answer:
y = - 3x + 10
Step-by-step explanation:
We have to write an equation of a straight line in slope-intercept form that passes through the points (3,1) and (0,10).
Now, the equation of the straight line (using two points form) will be
⇒ y - 1 = - 3(x - 3)
⇒ y - 1 = 9 - 3x
⇒ y = - 3x + 10 (Answer)
{Since the slope-intercept form of a straight line equation is y = mx + c}
We know the equation of a straight line when any two points on the straight line (
), (
) are known, will be
