A linear function does indeed form a line.
Answer: ( -6 , -6.5 )
Step-by-step explanation:
The formula for calculating Mid - point is given by
M = (
, 
)
= -5
= -7
= -9
= -4
substituting into the formula , we have
M = 
, 
M = 
, 
Therefore : mid point = ( -6 , -6.5 )
The coefficient of determination represents the percentage of the data that is the closest to the line of best fit.
the total variation in y can be explained by the linear relationship between x and y
300 x 1.05 = 315
315 x 1.05 = 330.75
330.75 x 1.05 = 347.2875
347.29
Answer:
720
Step-by-step explanation:
Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).
P(10,3)=10! / (10-3)!
= 10!/7!
Rewrite 10
! as
10 * 9 * 8 * 7
! / 7!
Cancel the common factor of 7
! and divide (
10 * 9 * 8
) by 1
10 * 9 * 8 = 720
