A discrete variable is a type of variable which contains a finite number of values. It usually takes its values from the set of whole numbers.
From the random variable described, the random variable that is descrete is "You measure the maximum heart rate in beats per minute".
This is because, heart rate cannot be partitioned it only takes counting number values. You either have 1 beat per minutes, 2 or 3 and so on beats per minute. But you cannot have 2.5 or 3.8 and so on beats per minute.
So heart rate cannot take decimal or fractional values and hence, it is a discrete random variable.
There would be no value to the laptop. If you’re looking for the actual value, it would be worth $-375.
if they double in size every 3 months and there are 12 months in a year, just multiply 250x4=1000 then multiply that by 2. 1000x2=2000
-4x = -5x - 9
9 = x

<span>B. 8.6
Let's substitute the given values into the function and calculate the result. So:
f(t) = Pe^rt
f(t) = 6e^0.06t
f(6) = 6e^(0.06*6)
f(6) = 6e^(0.36)
f(6) = 6*1.433329415
f(6) = 8.599976487
Rounding to the nearest tenth, gives: 8.6
So the answer is "B. 8.6"</span>
