Answer:
test statistic = 12.115
Step-by-step explanation:
Given data :
std = 2.1 years
n = 10
( std )^2 = 4.41
<u>determine the test statistic</u>
apply a two-tailed test ( chi squared test for one population variance )
test statistic
λ^2 = 
( Referring to Exhibit 11-1 )
= ( 10 - 1 )*(2.1)^2 / 3.2761
= 12.115
Answer:
False
Step-by-step explanation:
You first need to distribute the -4 to (x+4).
A is correct.
Work shown:
M- 6 packages delivered
T- 6+4=10
W- 6+6=12
Now add packages delivered each day
6+10+12=28

Please, in the future, post just one problem at a time.
Looking at Problem #1: The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1). At least, this is what I see; your graph is small.
-3-[-1]
The slope of that line is then m = rise / run = ------------ = +2.
0 - 1
[change in y]
Slope = m = rise / run = --------------------
[change in x]
The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.
