Y=4x−9 Complete the missing value in the solution to the equation
1 answer:
Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>Step-by-step explanation:
The complete question is
Complete the missing value in the solution to the equation. (3, ? )
By given, we know that , because coordinates are written like
.
Then, we replace the given coordinate to find .
Therefore, the missing value is 3, and the coordinates are (3,3).

Answer:
B -0.104
Step-by-step explanation:
Step 1: Write the formula for correlation
r = total xy
√Total x² x Total y²
Step 2: Make a table to calculate all values
Table is attached in the picture below
Step 3 : Solve
Mean of X = Total X/ Total number of X
= 507/12
= 106.33
Mean of Y = Total Y/ Total number of Y
= 1276/ 12
= 42.25
r = total xy
√Total x² x Total y²
r = -352.05/ √3656.25 x 3122.66698
r = -0.104
-0.104 is negative
This negative correlation means there is an inverse correlation between variables.
