Let us define each :
1. Natural numbers : the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
2.Whole numbers: Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)
3. Positive integers: The positive integers, z+ , consist of the whole numbers beginning with one.
4. Counting numbers: Any number you can use for counting things: 1, 2, 3, 4, 5, ... (and so on). Does not include zero.
So we can say that whole numbers is the odd one out, since it includes 0 and others dont.

Answer:
I am so lost but if it's how many honk out of how many you saw I would assume 7/7
Answer:

Step-by-step explanation:
The empirical rule, also referred to as "the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ)". The empirical rule shows that 68% falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).
And on this case since we are within 3 deviations (because we have 99.7% of the data between 568 and 1066hours), the result obtained using the z score agrees with the empirical rule.
So on this case we can find the standard deviation on this ways:
(1)
(2)
If we subtract conditions (2) and (1) we got:



Answer: A) y=25, B) y=10 C) y=-5 D)y=-20
Step-by-step explanation:
So whenever you have a question like this just plug in the values.
A) x=0
y= -3x+25 will now turn into y=0+25, so y=25
B) x=5
y= -3x+25 is now y= -15 +25, so y=10
C) x=10
y= -3x+25 is now y= -30+25, so y=-5
D) x=15
y=-3x+25 is now y= -45+25, so y=-20
