What is the definition of undefined term?

2 answers:

5 0

I think the answer is :

In Geometry, we have several undefined terms: point, line and plane. From these three undefined terms, all other terms in Geometry can be defined. ... The first term is point. The second term is plane. And the third undefined term is the line.

Hope This Helps.

The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100.

Mice21 [21]

Answer:

$1. x^2-10$ because the area expression can be rewritten as $(x^2-10)(x^2+10)$ which equals $(x^2-10)((x^2-10)+20).$

Step-by-step explanation:

Area of the rectangle $=(x^4-100)$

$x^4-100=(x^2)^2-10^2\\$Applying difference of two squares: a^2-b^2=(a-b)(a+b)\\(x^2)^2-10^2=(x^2-10)(x^2+10)$

Since the length of a rectangle is 20 units more than its width.

$Width: x^2-10\\Length=x^2+10=x^2-10+20$

The correct option is therefore 1.

Shalnov [3]

Answer:

a) $P(X=12)=(25C12)(0.6)^{12} (1-0.6)^{25-12}=0.0760$

b) $P(X>17) = P(X=18) +....+P(X=25)$

And we can use the following excel code: "=1-BINOM.DIST(17;25,0.6,TRUE)"

And we got:

$P(X>17) = P(X=18) +....+P(X=25)= 0.154$

c) $P(X$

And using the following excel code we got: "=BINOM.DIST(7,25,0.6,TRUE)"

And we got:

$P(X$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

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".

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:

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

The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by: $P(A)+P(A') =1$

Solution to the problem

Part a

$P(X=12)=(25C12)(0.6)^{12} (1-0.6)^{25-12}=0.0760$

Part b

For this case we want this probability:

$P(X>17) = P(X=18) +....+P(X=25)$

And we can use the following excel code: "=1-BINOM.DIST(17,25,0.6,TRUE)"

And we got:

$P(X>17) = P(X=18) +....+P(X=25)= 0.154$

Part c

For this case we want this probability:

$P(X$

And using the following excel code we got: "=BINOM.DIST(7,25,0.6,TRUE)"

And we got:

$P(X$

The measure of central angle QRS is StartFraction 8 pi Over 9 EndFraction radians. What is the area of the shaded sector? 36Pi u

MArishka [77]

The question is missing the figure. So, it is attached below.

Answer:

Area of the shaded sector is 144π units squared.

Step-by-step explanation:

Given:

Central angle of the sector is, $\theta=\frac{8\pi}{9}\ rad$

Radius of the circle is, $R=18\ units$

We know that, area of a sector of a circle of radius 'R' and central angle $\theta$ is given as:

$A=\frac{1}{2}R^2\theta$

Plug in $\theta=\frac{8\pi}{9},R=18$ . This gives,

$A=\frac{1}{2}\times (18)^2\times \frac{8\pi}{9}\\\\A=(\frac{324\times 4}{9})\pi\\\\A=(36\times 4)\pi\\\\A=144\pi\ units^2$

Therefore, the area of the shaded sector is 144π units squared.

Renting a truck costs $55.00 per day and $0.38 per mile when the driver goes beyond the 40 free miles allotted. How much would S

solmaris [256]

Well we need to multiply 55 by 2 because of the 2 days of renting. 55 * 2 = 110. Now we need to subtract 40 from 94 to find how many miles Samantha drove over 40. So 94 - 40 = 54. Now we need to multiply 54 by 0.38 to get the cost Samantha has to pay. 54 * 0.38 = 20.52. Finally we need to add the cost of 2 days of renting to the cost of the additional miles. 110 + 20.52 = 130.52. The total that Samantha has to pay for the truck is $130.52
I hope this was helpful and if so, please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!
