Answer:
$0.11 per pound
Step-by-step explanation:
15 - 3 = 12
12/112 = 0.10714286
= about 0.11
Answer:
A.
Step-by-step explanation:
He already had 100 into the account so we add that, 25x is derived from the fact that x=the amount of months and 25 is the amount per a month he saves.
Y=10
explanation:
-4•2= -8
2•4=8
-8+8=0
y=10
Answer:
1. Combining like terms
2. Distributive property
3. Subtraction (both sides)
4. Addition(both sides)
5. Division
Step-by-step explanation:
Answer:
42.1% of variation in the response is explained by the regression line
Step-by-step explanation:
Correlation coefficient is a measure which tells us that how strongly are two variables under study are linearly related to each other i.e correlation coefficient gives the strength of linear association between the variables.
If the magnitude of correlation coefficient is closer to 1, it indicates a strong linear relationship. If the magnitude of correlation coefficient is closer to 0, it indicates a weak linear relationship.
There is another variable known as "Coefficient of Determination", which is equal to square of Correlation Coefficient. Coefficient of Determination tells us that what percentage of variation in the response of the study can be explained by the regression line.
This means, for this question we need to calculate the Coefficient of Determination.
Correlation coefficient = r = 0.649
Coefficient of Determination = R = r² = (0.649)²= 0.421 = 42.1 %
This means that 42.1% of variation in the response is explained by the regression line.
