Answer:


Step-by-step explanation:
Given

Solving (a): The mean of the 6 samples.
This is calculated as:

So, we have:



Solving (b): The sample standard deviation.
This is calculated using:

So, we have:




E.
Fractions are just division.
In order for her to find the number of stars she needs to divide to find out how many she needs.
Answer:
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
equation:
3x -4
Answer:
1. - completed
2. expanded = a · a · a · a
3. base = a | exponent = 5 | expanded = a · a · a · a · a
4. - completed
5. base = c | exponent = 3 | expanded = c · c · c
6. base = c | exponent = 4 | expanded = c · c · c · c
7. base = m | exponent = 2 | expanded = m · m
8. base = m | exponent = 3 | expanded = m · m · m
9. power = y⁵ | base = y | exponent = 5
10. power = y⁸ | expanded = y · y · y · y · y · y · y · y

Answer:
Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.
Let me know if you'd like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.
