Hello there.
First, assume the numbers such that they satisties both affirmations:
- The sum of the squares of two numbers is .
- The product of the two numbers is .
With these informations, we can set the following equations:
Multiply both sides of the second equation by a factor of :
Make
We can rewrite the expression on the left hand side using the binomial expansion in reverse: , such that:
The square of a number is equal to if and only if such number is equal to , thus:
Substituting that information from in , we get:
Calculate the square root on both sides of the equation:
Once again with the information in , we have that:
The set of solutions of that satisfies both affirmations is:
This is the set we were looking for.
You would divide 0.01 by 100 to figure out how much 1 weighs, then multiply by 10. 0.0001 is the weight of 1 sample.
0.001 is 10
Answer:
A. 8.5
Step-by-step explanation:
is equivalent to 85 because
8.5 is in decimal.
remove the point from the middle and it will be 85 over 10.
As, given correlation coefficient for your data set is= -0.015
It means there is weak relation between two variables.If value of correlation coefficient is near to 1 or -1, it shows there is strong correlation.
Negative correlation means, if one quantity is increasing other is decreasing.So, the value of -0.015 shows that there is very less correlation between x and y values or two values in data set.
So, the chances are very less that predicted value will be reasonably close to the actual value as the points will be far from line of best fit.
