Answer:
see below
Step-by-step explanation:
side opposite 90 angle = x
sides opposite 45 angle = x
the multiplication and division by should be self explanatory
1. x = 5, y = 5
2. v = 10, u = 10
3. x = , y =
4. m = 5, n =
5. a = , b =
6. a = , b =
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.
