Answer:
-22
Step-by-step explanation:
18 + 4 = 22
then just add the negative to 22
-22
Answer:
-22
Step-by-step explanation:
-18 - 4 = 22
A) variance = 222.7, standard deviation = 49,595.9
B) variance = 49,595.9, standard deviation = 24,798
C) variance = 49,595.9, standard deviation = 222.7
D) variance = 57,861.9, standard deviation = 240.5
Answer:
Part 1) variance = 49,595.9
Part 2) standard deviation = 222.7
Option C
Step-by-step explanation:
we have
set of data
step 1
Find the mean
Adds the values and divide by the number of values
In this problem the number of values is 7
step 2
for each number: subtract the Mean and square the result
step 3
work out the mean of those squared differences
----> this value is called the "Variance"
step 4
The standard deviation is the square root of the variance
so
The standard deviation is equal to

Answer:
B. y = 2/3 x.
Step-by-step explanation:
The slope of the line = rise / run = 2/3.
The equation is y = 2/3 x.
Answer:
B. y = 2/3x.
This is your answer!
