The coefficient of correlation is independent of change of scale and origin of the variable X and Y. Change of origin means some value has been added or subtracted in the observation. If we divide all observations with x then new mean =initial mean/x.
Answer:
70
Step-by-step explanation:
You add all the numbers together and then divided by the number of numbers so
90+80+60+50=
280 divided by 4 is 70
The logarithm base 10 of the number 10 is 1
<h3>How to solve logarithm ?</h3>
We have to find logarithm base 10 of number 10.
Therefore, using logarithm rule
logₐ a = 1
Hence,
log₁₀ 10 = 1
Therefore, logarithm base 10 of the number 10 is 1

Grant needs to ride at least 13.33 miles to male at least $ 15.00 a day
<em><u>Solution:</u></em>
Given that Grant has an agreement with Brian to rent the bike for $35.00 a night
He charges customers $3.75 for every mile he transports them
Grant needs to make at least $15.00 a day
To find: miles needed to ride
From given question, He charges customers $3.75 for every mile he transports them
So if he transports for "x" miles he would get,
So the profit he gets is $ 3.75 and initial cost invested to rent bike is $ 35. Also, Grant needs to make at least $15.00 a day
So we can frame a inequality as:
So he needs to ride atleast 13.33 miles to male atleast $ 15.00 a day
