In which of the tables below x and y are inversely proportional? Find the constant of variation.

sertanlavr [38]

Answer:

In Table (b)

$k=30$

Step-by-step explanation:

By definition, Inverse proportion equations have he following form:

$y=\frac{k}{x}$

Where "k" is the Constant of proportionality.

Solving for "k":

$k=yx$

Having the values of "x" and "y" given in each table, you can check if the products of "x" and "y" is equal to a constant value.

Then:

(a) For $x=3;y=8$ :

$(8)(3)=24$

For $x=4;y=6$ :

$(6)(4)=24$

For $x=5;y=4.8$ :

$(4.8)(5)=24$

For $x=5.5;y=4$ :

$(4)(5.5)=22$

Since the product of the values of "x" and "y" is not constant, they are not inversely proportional.

(b) For $x=0.1;y=300$ :

$(300)(0.1)=30$

For $x=0.5;y=60$ :

$(60)(0.5)=30$

For $x=75;y=0.4$ :

$(0.4)(75)=30$

For $x=100;y=0.3$ :

$(100)(0.3)=30$

Notice that the Constant of proportionality is:

$k=30$

Therefore "x" and "y" are inversely proportional.

"What is the probability that in 10 dice throws, you will throw AT LEAST two ‘3’s on the dice? Assume you’re throwing a single d

dem82 [27]

Answer:

There is a 51.61% probability that in 10 dice throws, you will throw AT LEAST two ‘3’s on the dice.

Step-by-step explanation:

For each throw, there are only two possible outcomes. Either it is a '3', or it is not. This means that we solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

There are 6 possible outcomes for the dice. This means that the probability that it is a '3' is $\frac{1}{6} = 0.167$

There are 10 throws, so $n = 10$ .

Probability of throwing AT LEAST two ‘3’s on the dice?

Either you throw less than two, or you throw at least two. The sum of the probabilities of these events is 1. So

$P(X < 2) + P(X \geq 2) = 1$

$P(X \geq 2) = 1 - P(X < 2)$ .

In which

$P(X < 2) = P(X = 0) + P(X = 1)$ .

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{10,0}.(0.167)^{0}.(0.833)^{10} = 0.1609$

$P(X = 1) = C_{10,1}.(0.167)^{1}.(0.833)^{9} = 0.3225$

$P(X < 2) = P(X = 0) + P(X = 1) = 0.1609 + 0.3225 = 0.4834$ .

Finally:

$P(X \geq 2) = 1 - P(X < 2) = 1 - 0.4839 = 0.5161$ .

There is a 51.61% probability that in 10 dice throws, you will throw AT LEAST two ‘3’s on the dice.
