Answer:
Step-by-step explanation:
The 1 choice. The events are independent because P(red) ×P(green)= P(red and green)
Answer:
c. both
Step-by-step explanation:
Answer:
B) y = 9 x has Proportionality Constant = 9
Step-by-step explanation:
Two quantities P and Q are said to be PROPORTIONAL if and only if:
P ∝ Q ⇔ P = k Q ⇔ 
Here, k = PROPORTIONALITY CONSTANT
Given : k = 9
Now, let us consider the given expressions in which x ∝y
y = 81/3 x
Here, 
So, here Proportionality Constant ≠ 9
y = 9 x
Here, 
So, here Proportionality Constant = 9
y = 3 x
Here, 
So, here Proportionality Constant ≠ 9
y = 1/9 x
Here, 
So, here Proportionality Constant ≠ 9
Hence, only y = 9 x has Proportionality Constant = 9
Hi there!
We can find the zeros of a function by solving f(x) = 0. We find the following:

Add 300 to both sides.

Divide by 3.

Take the root and minus root of both sides.

Therefore, the zeros are
x = 10 and x = -10.
~ Hope this helps you!
