Answer:
-169 degrees
Step-by-step explanation:
It doesn't make much sense... but let's answer the question anyway.
First task is to determine what's the temperature outside at 2:30 PM.
We know that it's 11 degrees cooler than it was at 7 AM, so -4 - 11 = -15 degrees.
Abram's house is 4 degrees less than 11 times the outside temperature, so we can express that as:
House = 11 x - 4 - where x is the temperature outside.
If we replace the numbers we get: 11 * (-15) - 4 = -165 - 4 = -169 degrees
Abram's house is an extremely cold freezer!
I don’t know if you want us to do it for you or just explain it, but integers are all whole numbers so just like make a piece of art with the word integer surrounded by whole numbers or something right? Or like a poem about how most things in the world are in wholes idrk
Answer:

Step-by-step explanation:
Answer:
2.542
Step-by-step explanation:
Given the data :
Customer Pre-training Survey, x1 __Post-training Survey, x2 __ difference, d = (x2-x1)
A 6 8 2
B 5 5 0
C 10 10 0
D 7 10 3
E 6 8 2
F 5 6 1
G 2 8 6
This is a paired test as each subject has two different data values :
Difference in score, d :
dbar = Σd / n
dbar = (2+0+0+3+2+1+6) /
dbar = 14 / 7
dbar = 2
Standard deviation of d ; Sd = √[Σ(d - dbar)²/n-1]
Using calculator ; Sd = 2.082
Test statistic = dbar ÷ (Sd/√n)
Test statistic = 2 ÷ (2.082 / 7)
Test statistic = 2 ÷ 0.7869220
The statistic = 2.5415
