The numeric constant of variation is 100
Step-by-step explanation:
Direct proportion means that increase in one variable cause increase in other variable
Here,
It is given that
y varies directly as x
y∝x
when the proportionality symbol is removed a proportionality constant is introduced
Given that
y = 100 when x = 4
Putting the values
The numeric constant of variation is 100

The best form to use is standard form, which is, y=ax^2+bx=+c.
The answer is two hundred thirty four.
<span>you need to set up the equations solve for x or y. and substitute. I can give you the starting equations, but i cant find the answer and I don't remember how to do all the steps, but the first two equations (the ones you use to solve for x or y to use to solve for a number to subsitute. x-12=y y-14=3x and there should be one more for that they met two years ago.</span>
Answer:
The answer is 
Step-by-step explanation:
If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5
Thus, P(identify tap water)=0.5
The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities
- 8 of 9 people identified correctly or
- 9 of 9 people identified correctly
Since P(identify tap water)=0.5 each probabilities are the same and equal to
=
So we have 
=
