Answer:
Step-by-step explanation:
The range would only include positive integers.
Answer:
Infinite.
Step-by-step explanation:

Expand:

Add 6 to both sides:


Subtract 3x from both sides:


No matter what x is, it doesn't affect the answer. Thus, the equation is true for all values of x.
Answer:
Step-by-step explanation:
joint porbability formula
0.23*0.73*0.74 = 0.124246
Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
