Which number is prime 9,10,11,12
Answers
Answer:
11
Step-by-step explanation:
A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
A prime number is a number that cannot be factored other than 1 and that number is self.
For example, 9 can be written as 3 x 3 thus it will not prime number and 11 cannot be written as two products other than 1 x 11 thus it will be a prime number.
Hence "A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number".

Answers
Answer:
look at this dudeee
Surface area of the prism given is 46 inches².
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object
Given net of a prism.
The given net consists of three rectangles and two triangles.
Find the area of each of the two dimensional figures.
Given, the bases are isosceles triangles.
So the two rectangles are of dimensions 5 inch × 2.5 inch and third rectangle is of the dimensions 5 inch × 3 inch.
Total area of the rectangles = (5 × 2.5) + (5 × 2.5) + (5 × 3)
= 40 inches²
Area of two triangles = 2 × [tex]\frac{1}{2 }[/tex] × 3 × 2
= 6 inches²
Surface area of the prism = 40 inches² + 6 inches² = 46 inches²
Hence the required area is 46 inches².

A normal six-sided die is thrown once. The number of outcomes in the sample space is
Answers
The number of outcomes in the sample space is 6.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
When you roll a 6 sided dice, number of dots on uppermost face is called as outcome. Now, whenever a dice is rolled we can get either 1, 2,3,4,5 or 6 dots on the upper most face that is now outcome.
So experiment here is "Rolling a 6 faced dice" and list of possible outcomes is "{1,2,3,4,5,6}".
Sample space by its definition is list of all the possible outcomes of an experiment.
S={1,2,3,4,5,6}
Hence, the number of outcomes in the sample space is 6.

A researcher for a travel company is looking into the prices people are willing to pay for airplane tickets. The company has communicated that the overall population mean is $265 with a standard deviation of $40.93. The researcher has a sample of 130 ticket purchases from one location.
By the central limit theorem, which interval can the researcher be 95% certain that the sample mean will fall within?
Answers
From the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.
How to use the Central limit theorem?
We are given;
Population Mean; μ = $265
Population standard deviation; σ = $40.93
Sample size; n = 130
The central limit theorem (CLT) postulates that the distribution of sample mean approximates a normal distribution with larger sample sizes, disregarding the population's distribution.
This implies that sample sizes equal to or greater than 30 are often considered sufficient for the Central limit theorem to hold.
Thus, by the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

D. 192
E. 9854.05
F. 9843.75
G. 55
H. 1
Answers
This would be a simple area problem with a triangle. REMEMBER THIS EQUATION: a=bh*1/2 (b for base and h for height, these are multiplied together then that answer is halved out.)
So we just need to plug in our values into the equation, so the equation would look like a= (16)*(24)*1/2. 16 times 24 would then give you 384, you could either divide by 2 or multiply by 0.5 to get the next answer, as long as your HALVING the answer.
So we have our bh value so now we can multiply by 1/2 which will give us 384*1/2 which leaves us with 192.
I have also attached a photo of doing a longer(ish) way than this, that also proves that this equation works. Either one will provide you an answer.
if cot theta = -2, find the value of cot theta + cot (theta -pi) + cot (theta-2pi)
Answers
Given:
[tex]\cot \theta = -2[/tex]
To find:
The value of [tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex].
Solution:
We know that,
[tex]\cot (\theta -n\pi)=\cot \theta[/tex] ...(i)
Where n is an integer.
We have,
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex]
Using (i), it can be written as
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=\cot \theta +\cot \theta +\cot \theta [/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3\cot \theta[/tex]
It is given that [tex]\cot \theta = -2[/tex].
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3(-2)[/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=-6[/tex]
Therefore, the value of the given function expression is [tex]-6[/tex].
