since it varies directly, we form an equation ,
Y =kX where k is a constant
use the points given to find K ,
3 =0.2k , k = 15
So to get final answer,
when x = 1
y = kx, = 1(15)
y= 15
Hence when x=1, < y = 15 >
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.

Answer:
A ; y = 2229-x
Step-by-step explanation:
The question is asking for us to find how many seats are left that can be sold. There are 2463 total seats, 234 reserved seats, and x non-reserved seats.
If we subtract the 234 reserved seats from total seats, we will get 2229, the number of non-reserved seats and the not sold seats.
Since x is the non-reserved seats, we can subtract x from 2229 to get the number of seats that aren't sold.
Pyramids were important because they once housed the ancient Pharaohs and Queens. Hope this helped!
