As x increases, y increases. So this data has a positive association. The association looks to be strong, as the values all follow the trend pretty closely.
Answer=Strong Positive
Is the last one
(-Infinity, -3] U (-1, positive infinity)
A triangular prism Vol. = area (A) of the triangular base × height (h) of prism
A triangular pyramid V = A × 1/3 h
So since they have same base A and h, the V of the pyramid will be exactly 1/3 the V of the prism
Answer:
By breaking it up in shapes
Step-by-step explanation:
I annotated your photo and it's attached below :) that's an example on how to break shapes into easier parts. So yeah
For example, exc. 15.
x + y = 10 and 6/x = 9/y; You need y!
=> x = 10 -y and 9x = 6y => 9(10-y) = 6y => 90 - 9y = 6y => 15y = 90 => y = 6.
