Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
Answer:
- There is no power of 2 that is equal to 0.
- Its inverse does not have any x-intercepts.
Step-by-step explanation:
Given the function
This function can be written as:
As the rule tells s that
so
As we know that the value of x=0 at y-intercept.
For any value of 
, this statement is false as there is no power of 2 that is equal to 0.
Also
Lets interchange x and y in the equation to find the inverse of the function.
So, it doesn't have any x-intercepts as for any value of x, the value of can not be zero for this function.
Therefore, Its inverse does not have any x-intercepts.
Lets use this set of data as an example:
2,2,3,3,3,3,4,4,5
Median is the data number that is in the middle of all of the numbers when arranged from least to greatest.
The median would be 3 since its in the middle. THINK: Median=Medium
Range is the highest number minus the lowest number. This is easy.
5-2=3
So the range is 3.
The mode is the number that you see the most often. 3 is the most since there are four 3s. There can be more than one mode or even no mode. THINK: Mode=Most
The mean is all of the numbers added together and then divided by the number of numbers.
2+2+3+3+3+3+4+4+5= 29
29 divided by 9 = 3.2222222222(repeated)
The mean can also be called the average.
I hope this helps!!!
Answer:
m=7/4 or 1.75
Step-by-step explanation:
You have the equation:
y₂-y₁
m= -------
x₂-x₁
The coordinates (0,-5) are the first pair, so:
0=x₁
-5=y₁
The coordinates (4,2) are the second pair, so:
4=x₂
2=y₂
Substitute those in, and you get:
2-(-5)
m= ---------
4-0
Simplify and solve:
2+5 7
m= ------ = ---- or 1.75
4 4
