The simplification of the number 2√15 is 7.74.
What is defined as taking square root?Squaring a number would be the inverse operation of square rooting it.
The square of a number is really the value obtained by multiplying the number by itself, whereas the square root of such a number is obtained by locating a number that, when squared, yields the original number. If 'a' has been the square root of 'b,' then a × a = b.A number's square root is the value of power 1/2 of such a number. In all the other phrases, it is the number for whom product yields the original number on its own. It is represented by the symbol '√ '. The square root sign is known as a radical, and the number beneath it is known as a radicand.The given expression is;
= 2√15
For finding the value of √15; use long division method.
√15 = 3.87
Put the value;
= 2 × 3.87
= 7.74.
Thus, the value of the expression is found as 7.74.

Solve for x, given the equation square root of x plus 9 − 4 = 1. (2 points)
Answer:
x = 16
Step-by-step explanation:
A test has twenty questions
worth 100 points. Some
questions are worth three points,
some are worth eleven points.
How many three-point questions
are there? How many eleven
point questions are there?
There are 5 11 pointer questions and 15 3 pointer questions
We are given that total points of the test is 100
The test contains questions of two markings 3 points and 11 points
It is given that the total number of questions is 20
Let the number of three pointer questions be 'x' and the number of 11 pointer questions be 'y'
Thus total number of questions=x + y =20
Now the total sum of all the points comes to 100
Therefore,
3x+11y =100
x + y =20
x= 20-y
Now putting the value of x in the other question,
3(20-y) +11y =100
60-3y +11y=100
8y=100-60
8y=40
y=5
Thus x=20-y=20-5=15
Thus there are 5 11 pointer questions and 15 3 pointer questions

So, we have:
y = f(x - 3) + 2

a positive five-digit integer is in the form $ab,cba$; where $a$, $b$ and $c$ are each distinct digits. what is the greatest possible value of $ab,cba$ that is divisible by eleven?
The required positive five-digit integer of the form ab,cba; which should be divisible by 11 is 87,978
Explain the divisibility test of 11.
For a number to be divisible by 11, the difference between the sum of its odd digits (1st, 3rd, 5th...) and the sum of its even digits (2nd, 4th...) must be divisible by 11.
Calculation for the positive five-digit integer of the form ab,cba to be divisible by 11
Required 5 digit number is of the form, ab,cba
Using the divisibility test of 11, we get
(b + b) - (a + c + a) to be divisible by 11
i.e. 2b - (2a + c) to be divisible by 11
Replacing ab,cba using the greatest numbers, such as 7, 8 and 9 and checking its divisibility with 11
78,987 = 2*8 - (2*7 + 9) = 16 - (14 + 9) = 16 - 23 = -7 NO
87,978 = 2*7 - (2*8 + 9) = 14 - (16 + 9) = 14 - 25 = -11 YES
79,897 = 2*9 - (2*7 + 8) = 18 - (14 + 8) = 18 - 22 = -4 NO
97,879 = 2*7 - (2*9 + 8) = 14 - (18 + 8) = 14 - 26 = -12 NO
89,798 = 2*9 - (2*8 + 7) = 18 - (16 + 7) = 18 - 23 = -5 NO
98,789 = 2*8 - (2*9 + 7) = 16 - (18 + 7) = 16 - 25 = -9 NO
Thus, a positive 5-digit number is 87,978
Hence, the required positive five-digit integer of the form ab,cba; which should be divisible by 11 is 87,978

50% don't smoke, 20% light smokers, 30% heavy smokers heavy smokers twice as likely to die as light smokers, light smokers twice as likely to die as nonsmokers probability of being a heavy smoker given person died?
The probability of person being a heavy smoker given person died is 0.57 .
Baye's Theorem helps in finding the probability of any event A given that event B has already occurred.
For Example the probability of event A given that event B has already occurred is denoted by
[tex]P(A/B)=\frac{P(B/A)P(A)}{P(B)}[/tex]
In the given question
Let H denoted heavy smokers , L denote Light smokers , N denote Non smokers.
Given the probability of non smokers P(N) = 50%=0.5
the probability of light smokers P(L)=20%=0.2
the probability of heavy smokers P(H)=30%=0.3
let P(D/H) denoted the person died given he was a heavy smoker.
let P(D/L) denoted the person died given he was a light smoker.
let P(D/N) denoted the person died given that he was a non smoker.
According to question
"heavy smokers twice as likely to die as light smokers" means
P(D/H)=2P(D/L)......(1)
and "light smokers twice as likely to die as nonsmokers" means
P(D/L)=2P(D/N)
On simplifying we get
[tex]P(D/N)=\frac{1}{2} P(D/L)\\ \\ P(D/N)=0.5 P(D/L)[/tex].....(2)
According to Baye's Theorem
[tex]P(H/D)=\frac{P(D/H)P(H)}{P(D/N)P(N)+P(D/L)P(L)+P(D/H)P(H)}[/tex]
Substituting values of P(D/H) from ...(1) and values of P(D/N) from ....(2)
we get [tex]P(H/D)=\frac{2*P(D/L)P(H)}{0.5*P(D/L)P(N)+P(D/L)P(L)+2*P(D/L)P(H)}[/tex]
taking P(D/L) common from each term
[tex]P(H/D)=\frac{P(D/L)}{P(D/L)} (\frac{2*P(H)}{0.5*P(N)+P(L)+2*P(H)})[/tex]
[tex]P(H/D)= (\frac{2*P(H)}{0.5*P(N)+P(L)+2*P(H)})[/tex]
Substituting the values of P(N), P(H), P(L) from above we get
[tex]P(H/D)= (\frac{2*(0.3)}{0.5*(0.5)+(0.2)+2*(0.3)})[/tex]
[tex]P(H/D)= (\frac{0.6}{0.25+0.2+0.6})[/tex]
=[tex]\frac{0.6}{1.05}=0.57[/tex]

From trial to trial, the likelihood of success, given by the symbol, stays constant. There are n independent trials. The binomial distribution is a probability distribution that summarizes the possibility that a value will take one of two independent values under a given set of parameters or assumptions, which means the result of each trial has no bearing on the results of the others. The fundamental presumptions of the binomial distribution are that there is only one possible result for each trial, that each trial has the same success probability, and that each trial is independent of the others or mutually exclusive.

What is a quadratic function?A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the standard form of a quadratic equation is given by;

y = -0.4908(10)² + 5.8845(10) + 1.3572
y = -0.4908(100) + 58.845 + 1.3572

A group of students is asked if they travel; to school by car, students travelling by car = 14 students not travelling by car=11 what percentage of these students do not travel to school by car?????
Answer: 44%
Step-by-step explanation:
To find the percentage of students who do not travel by car, we first need to find the total number of students.
14 + 11 = 25
So out of the total of 25 students, 11 do not travel by car, so to find that percentage we will divide the number that do not travel by car by the total number.
11/25 = 0.44
We have the percentage as a decimal. To convert the decimal to a percent we multiply it by 100.
0.44 x 100 = 44%
