The equation 2y = 8x represents a proportional relationship. What is the constant of proportionality?
Sphinxa [80]

Answer:

C) 4

Step-by-step explanation:

Given equation:

2y=8x

The above equation represents proportional relationship.

To find the constant of proportionality.

Solution:

<em>The equation representing proportional relationship is given by:</em>

<em>y=kx</em>

<em>where k represents constant of proportionality.</em>

So, in order to find the value of k for the given proportionality relationship, we will solve for y

We have:

2y=8x

Solving for y

Dividing both sides by 2.

\frac{2y}{2}=\frac{8x}{2}

y=4x

∴ k=4

Thus, the constant of proportionality = 4.

S_A_V [24]
Probability=number of specific outcomes/total possible outcomes

And the probability of two events happening at the same time is P(1)*P(2), or the product of the probabilities of each event...

In this case:

P(primary color)=3/6=1/2

P(head)=1/2

P(primary and head)=(1/2)(1/2)=1/4
