Your question has been heard loud and clear
√-36 is by no means a real number. This is because square roots can only be positive in nature.
Eg: -2*-2 = 4 and 2*2 = 4 , so √4 = -2 or 2 but √-4 doesnt exist.
So , √-36 also does not exist while √36 exists.
√-36 , we can however represent it as an imaginary number as 36i

The value of the expression 4a² - 4ab + b² is 1 if the value of a is 2, and the value of b is 5.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The expression:
= 4a² - 4ab + b²
Plug a = 2
b = 5
In the above expression:
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Applying arithmetic operation:
= 4(2)² - 4(2)(5) + (5)²
= 4x4 - 40 + 25
= 16 - 40 + 25
= 1
Thus, the value of the expression 4a² - 4ab + b² is 1 if the value of a is 2, and the value of b is 5.

Determine whether the given value is a statistic or a parameter.
A survey found that 75% of all respondents were optimistic.
Choose the correct answer below.
A. The value is a parameter because it is a numerical measurement describing some characteristic of a sample.
B. The value is a parameter because it is a numerical measurement describing some characteristic of a population. C. The value is a statistic because it is a numerical measurement describing some characteristic of a population.
D. The value is a statistic because it is a numerical measurement describing some characteristic of a sample.
Answer:
D. The value is a statistic because it is a numerical measurement describing some characteristic of a sample.
Step-by-step explanation:
A survey found that 75% of all respondents were optimistic. We consider 75% of all respondents is a sample from over all population, so it's a statistic. Value of statistics are e.g sample mean, sample proportion etc .
It is important to understand that the numerical measurement describing some characteristic of a population is called as parameter. e.g. population mean , population proportion etc. Hence, it is not correct.
If point p partitions line BA,what would be the part to whole ratio
Answer:
4 / 5
Step-by-step explanation:
From the image attached, Line BA is divided into a total of 5 equal proportions (or intervals). Point P is placed at the 4th proportion of the divided line, also the distance between point P and point A is 1 propotion. The ratio in which point P divides the line BA is given as:
Ratio = BP : PA = 4 : 1
Ratio = 4 : 1
The part to whole ratio If point p partitions line BA = BP / BA = 4 / 5
Part to whole ratio = 4/5
Between 2000 and 2015 , the number of twin births in a certain country increased by 11%, to approximately128,760 . About how many twin births were there in 2000?
Answer:
116000
Step-by-step explanation:
The number of twins in 2000 is x
the number increases by 11% to year 2015
x(1+11/100 )=128760
x+0.11x=128760
1.11x=128760
x=128760/1.11
x=116000

60-49=x
x=11
You are shopping for dinner for your family in a fast-food restaurant, but you are concerned about fat. An informative menu gives you the following information. Item Hamburger Chicken sandwich Fries Onion rings Grams of fat 24 13 30 25 How much total fat is in an order of hamburgers, chicken sandwich, orders of fries, and orders of onion rings
Answer:
Total amount of fat = 92 grams
Step-by-step explanation:
Given:
Item Amount of fat (in gram)
Hamburger 24
Chicken sandwich 13
Fries 30
Onion rings 25
Find:
Total amount of fat
Computation:
Total amount of fat = [Hamburger + Chicken sandwich + Fries + Onion rings]
Total amount of fat = [24 + 13 + 30 + 25] grams
Total amount of fat = 92 grams
Suppose X has a continuous uniform distribution over the interval [−2,2]
a) Determine the mean, variance, and standard deviation of X
b) Determine the value of a such that P(−a
Answer:
Mean = 0
Variance = 4/3
Standard Deviation √4/3
a= 0.9
Step-by-step explanation:
If X has a uniform distribution over [a,b] then its Mean is a+b/2 and variance is (b-a)²/12
Here a= -2 and b= 2
Now finding the mean = a+b/2=-2+2/2= 0
Variance = (b-a)²/12=( 2-(-2))²/12= 4²/12= 16/12= 4/3
Standard Deviation = √Variance= √4/3
b) [tex]\int\limits^a_b f({x}) \, dx[/tex]= \int\limits^a_a {\frac{1}{a- (-a)} } \, dx
=1/2a[x]^a_-a= 2a/2a= 1 (applying the limits to the function)
P(−a<X<a) =[tex]\int\limits^a_b {x} \, dx[/tex]=1/2 * 2a= a (applying the limits to the function)
P(−a<X<a)= 0.9
a= 0.9
In the given question the limits are -a to a . When we apply these in the above instead of [a,b] we get the above answer.
Using the uniform distribution, we have that:
The mean is 0.The variance is of 1.25.The standard deviation is of 1.12.An uniform distribution has two bounds, a and b.
In this problem, interval [−2,2], hence [tex]a = -2, b = 2[/tex].
The mean is:
[tex]E(X) = \frac{a + b}{2}[/tex]
Hence:
[tex]E(X) = \frac{-2 + 2}{2} = 0[/tex]
The variance is:
[tex]V(X) = \frac{(b - a)^2}{12}[/tex]
Hence
[tex]V(X) = \frac{(2 - (-2))^2}{12} = \frac{16}{12} = 1.25[/tex]
The standard deviation is the square root of the variance, hence [tex]\sqrt{1.25} = 1.12[/tex]

Which number is a counterexample to the following statement? All numbers that are divisible by 2 are divisible by 4.
A. 0
B. 12
C. 28
D. 42
Using divisibility concepts, a counterexample to the statement is given by option the number 42, option D.
-------------
If the remainder of the division of A by B is 0, it is said that A is divisible by B.-------------
In option A, 0 is divisible by both 2(0/2 = 0) and 4(0/4 = 0), so it is not a counterexample.In option B, 12 is divisible by both 2(12/2 = 6) and 4(12/4 = 3), so it is not a counterexample.In option C, 28 is divisible both by 2(28/2 = 14) and 4(14/2 = 7), so it is not a counterexample.In option D, 42 divided by 4 is 10 with a remainder of 2, thus 42 is not divisible by 4, being a counterexample to the statement.A similar problem is given at https://brainly.com/question/24354438

Rational. the square root of 3600 is a real, rational number, 60.
Step-by-step explanation:
Answer: Rational
Step-by-step explanation:
THREE WAYS TO DETERMINE:
If the number given is an integer, it is rational.
If the number given is fraction, it is rational.
If the number given is decimal, as long as it is terminating or repetitive decimal, it is rational. (Because then you can write it as a fraction which leads to the second point)

What is the value of f^-1(0)?
Please help! It’ll be greatly appreciated!
Answer:
[tex]f^{-1}(0)=6[/tex]
Step-by-step explanation:
So, we have the graph y=f(x).
And we want to find:
[tex]f^{-1}(0)[/tex]
Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:
[tex]f^{-1}(0)=y[/tex]
This means that we have the point:
[tex](0,y)[/tex]
So, to find our solution, we will swap the x- and y-coordinates. This gives us:
[tex](x,0)[/tex]
So, simply need to find the x-coordinate such that y is 0.
From our graph, we can see the point (6,0). In other words:
[tex]f(6)=0[/tex]
So:
[tex]f^{-1}(0)=6[/tex]
And we're done!
