I guess this will help you
Step-by-step explanation:
30 , 60 , 90 , 120, 150
,LCM of 12 and 30 is 60
The least-square regression line has a slope of:
m=(nΣxy-ΣyΣx)/(nΣx²-ΣxΣx)
and a y-intercept of:
b=(Σy-mΣx)/n
In this case: n=7, Σxy=4899, Σy=391, Σx=85, Σx²=1153 so
m=(7(4899)-391*85)/(7(1153)-85*85))=1058/846
b=(391*846-85*1058)/(7*846)=34408/846
So the line of best fit is:
y=(1058x+34408)/846 and if we approximated this as your answers see to have done....
y=1.25x+40.67
Answer:
I think, yes?
Step-by-step explanation:
Answer:
k = 5
Step-by-step explanation:
-2k = k - 7 - 8
Combine like terms
-2k = k - 15
add 15 to both sides
-2k + 15 = k
Add 2k to both sides
15 = 3k
Divide both sides by 3
k=5

Question: What is a verbal expression for w-24
Answer: What is a 24 less than a number <em>w.</em>
Explanation: It would be (What is a 24 less than a number <em>w.</em>), because less than means subtract and you will write it the opposite of how you say it.
