EleoNora [17]

Answer:

400 Dollars

Step-by-step explanation:

It is 400 dollars since 5 yards and 4 yards which are the dimensions of this room is multiplied together, it is 20 and each square yard is 20 dollars which concludes you to multiply 20 by 20 and gives us the answer 400.

Which figure has a perimeter closer to the circumference of a circle, a regular polygon with 24 sides or a regular polygon with

Mandarinka [93]

Answer:

A regular polygon with 48 sides

see the explanation

Step-by-step explanation:

we know that

As the number of sides of a regular polygon increase, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle

As the number of sides of a regular polygon increase, the polygon gets closer and closer to a true circle

therefore

A regular polygon with 48 sides, because as the number of sides of a polygon 48, the perimeters of the polygons get closer to the circumference of the circle

In a list of households, own homes and do not own homes. Five households are randomly selected from these households. Find the p

Paladinen [302]

Answer:

The probability of success for this case would be:

$p =\frac{9}{15}= 0.6$ representing the proportion of homes that are own homes

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=15, p=0.6)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

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

And we want this probability:

$P(X=3)$

And uing the probability mass function we got:

$P(X=3)= 15C3 (0.6)^3 (1-0.6)^{15-3}= 0.00165$

Step-by-step explanation:

Adduming the following info: In a list of 15 households, 9 own homes and 6 do not own homes. Five households are randomly selected from these 15 households. Find the probability that the number of households in these 5 own homes is exactly 3.

Round your answer to four decimal places

P (exactly 3)=

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

The probability of success for this case would be:

$p =\frac{9}{15}= 0.6$ representing the proportion of homes that are own homes

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=15, p=0.6)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

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

And we want this probability:

$P(X=3)$

And uing the probability mass function we got:

$P(X=3)= 15C3 (0.6)^3 (1-0.6)^{15-3}= 0.00165$
