0.29m+10=0.35m
0.29m-0.29m+10= 0.35m-0.29m
10=0.06 m
Divide by 0.06 for 10 and 0.06
10/0.06= 0.06/0.06 m
m= 166.66666
Answer is m = 166.66666- the number 6 continues
Answer:
1395 times.
Step-by-step explanation:
The Williams family open their door 28 + 17 = 45 times a day.
So in October they opened it 31 * 45 = 1395 times.
Answer:
a)
b) r =-0.932
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained by the linear model is 86.87%.
Step-by-step explanation:
Assuming the following dataset:
Monthly Sales (Y) Interest Rate (X)
22 9.2
20 7.6
10 10.4
45 5.3
Part a
And we want a linear model on this way y=mx+b, where m represent the slope and b the intercept. In order to find the slope we have this formula:
Where:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Part b
For this case we need to calculate the correlation coefficient given by:
So then the correlation coefficient would be r =-0.932
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained by the linear model is 86.87%.
