We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
6a-6n+36
Step-by-step explanation:
-10a-9n+16-30+3n+15a+50+a
Combine a...
-10a+15a= 5a+a=6a
Combine n...
6a-9n+16-30+3n+50
-9n+3n= -6n
6a-6n+ 16-30+50
Combine # w no variable
Answer: 6a-6n+36
The number of people in the auditorium can be less than or equal to 420 so let p represent the number of people
The inequality is p≤420
Answer:
Yes
Step-by-step explanation:
Statement 1: If JK and LM bisect each other then, they divide each other in 2 equal parts.
So,
JP = PK [Because of statement 1]
MP = PL [Because of statement 1]
∠JPM = ∠LPK [Because they are vertically opposite angles]
So, ΔJPM ≅ to ΔKPL [By SAS congruence criteria of triangle]
