Probabilities are used to represent the possibilities of events.

The probability that a student participates in a club given that he participates in sports is 0.6561

The required probability is represented as; P(Club | Sport)

And it is calculated using:

P(Club | Sport) = \frac{n(Club\ n\ Sport)}{n(Sport)}

From the table, we have:

n(Club\ n\ Sport) = 620

n(Sport) = 945

So, the equation becomes

P(Club | Sport) = \frac{620}{945}

P(Club | Sport) = 0.6561

Hence, (d) 06561 is correct.

timurjin [86]

Answer:

Option B.

Step-by-step explanation:

Two events are said to be independent of each other, if the probability of one event ocurrin in not way affects the probability of the other event occurring.

The interception of two independent events P(A ∩ B) = P(A) × P(B), where:

P(A) = 0.70

P(B) = 0.20

P(A ∩ B) = P(A) × P(B) = 0.70x0.20 = 0.14

The two events are independent if the probability of buying Bread AND cheese equals: 0.14, which is Option B.

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.
