- Discrete
- Continuous
- Discrete
- Continuous
==============================================
Explanations:
- This is discrete because we can't have half a basketball, or any non-whole decimal value to represent the number of basketballs. We can only consider positive whole numbers {1,2,3,4,...}. A discrete set like this has gaps between items. In other words, the midpoint of 2 and 3 (the value 2.5) isn't a valid number of basketballs.
- This is continuous because time values are continuous. We can take any two different markers in time, and find a midpoint between them. For example, the midpoint of 5 minutes and 17 minutes is 11 minutes since (5+17)/2 = 22/2 = 11. Continuous sets like this do not have any gaps between items. We can consider this to be densely packed.
- This is the same as problem 1, so we have another discrete function. You either score a bullseye or you don't. We can't score half a bullseye. The only possible values are {1,2,3,4,...}
- This is similar to problem 2. This function is continuous. Pick any two different positive real numbers to represent the amount of gallons of water. You will always be able to find a midpoint between those values (eg: we can have half a gallon) and such a measurement makes sense.
So in short, always try to ask the question: Can I pick two different values, compute the midpoint, and have that midpoint make sense? If so, then you're dealing with a continuous variable. Otherwise, the data is discrete.
Can you add the question please.
2 decimal places for regular . 3.14
The error in Jerry's calculation is 4.84
The number of employees, N = 4
The mean is calculated as:
The formula for the standard deviation is:
This can be further calculated as:
Jerry thinks the Standard Deviation = 8
The true Standard Deviation = 3.16
Error = |True value - Measured value|
Error = |3.16 - 8|
Error = 4.84

Answer:
y= 1/4,1/2,1,2,4,8,16,32,64
Step-by-step explanation:
Make negative powers positive by turning them into a fraction so 
is really
= 
so 
is just 
. then 
=1 [any number to the zero power is = 1],
2^1 = 2, 2^2=4, 2^3=8, 2^4=16, 2^5=32, 2^6 = 2x2x2x2x2x2=64
