<span>The coefficient of
determination is presented by R</span>²<span> is mostly used in the analysis of regression
where it is the proportion of the variance in the dependent variable that is
predictable from the independent variable. The range of values between the predicted
scores and the actual scores is between 0 to 1. The closer the value to 1, the
greater is the relationship between variables and has lesser errors. For example,
if there is an R</span>²<span> of 0.80, then it means that 80% is predictable. R</span>² can be obtained using excel as trendline or with the use of formula.
Answer:
100 (+1) x 2^t = 100 (+2et) as we plus and we multiply before squaring the years.
Step-by-step explanation:
You can now work this out as +1 represents the 100% + 200% sum.
c. 9
To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.





Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right
Answer:
24x^2
