The value of y - intercept is: -5
What is Y Intercept?It is distance between point on Y axis where graph cuts it and origin generally denoted by c.
Here in this question initially f(x) was = x
later we took new function g(x) = f(x-5) = x-5
therefore we call g(x) = x - 5now we need to find y intercept and we know that on y axis (x - coordinate = 0)
just put x=0 in above equation g(0) = -5
which is value of y intercept
y = -5
why this is y intercept?because one point is origin(0,0) and other is this one(0,-5)we need to calculate distance between these 2 that after finding from distance formula we get answer as 5 but here intercept is negative so, our final answer is -5

If X1 , X2 , X3 and X4 are (pairwise) uncorrelated randomvariables, each having mean 0 and variance 1, compute thecorrelations coefficient of(a) X1 + X2 and X2 + X3 ;(b) X1 + X2 and X3 + X4
The correlation coefficient of
(a) X1 + X2 and X2 + X3 would be 1/2.
(b) X1 + X2 and X3 + X4 would be 0.
What is the correlation in statistics?
Correlation is a statistical measure (a number) that describes the magnitude and direction of a relationship between two or more variables. A correlation between variables, on the other hand, does not imply that a change in one variable is the cause of a change in the values of the other variable.
(a) X1 + X2 and X2 + X3.
We have
Cov(X1 + X2, X2 + X3) = Cov(X1, X2) + Cov(X1, X3) + Cov(X2, X2) + Cov(X2, X3)
= 0 + 0 + Var(X2) + 0
= 1.
We know that
Var(X1 + X2) = Var(X1) + Var(X2) + 2 Cov(X1, X2) = 1 + 1 + 2 · 0 = 2.
Similarly, Var(X2 + X3) = 0. So the correlation between X1 + X2 and X2 + X3 is
[tex]=\frac{Cov(X1+X2, X2+X3)}{\sqrt{Var(X1 + X2) Var(X2 + X3)} }\\\\=\frac{1}{\sqrt{2.2} }\\\\=\frac{1}{2}[/tex]

Since
Cov(X1 + X2, X3 + X4) = Cov(X1, X3) + Cov(X1, X4) + Cov(X2, X3) + Cov(X2, X4)
= 0 + 0 + 0 + 0
= 0,
the correlation between X1 + X2 and X3 + X4 is 0.
Hence, the correlation coefficient of X1 + X2 and X2 + X3 would be 1/2

Consider this equation. if is an angle in quadrant iv, what is the value of ? a. b. c. d.
Option (a) is correct. The value of sinθ will be [tex]-\frac{5\sqrt{41} }{41}[/tex]
We are given the value of the cosθ = [tex]\frac{4\sqrt{41} }{41}[/tex] where, θ is in the IV Quadrant.
We know that cosine is the ratio of the adjacent side to the hypotenuse. Also, we have
hypotenuse = h = 41, And Adjacent Side = b = [tex]4\sqrt{41}[/tex]
So, for the value of the opposite side, we need to use the Pythagorean theorem which is stated as:[tex](Hypotenuse)^{2} = (opposite side)^{2} + (adjacentside)^{2}[/tex]
[tex]h^{2} = a^{2} + b^{2}[/tex]
[tex]a^{2} = h^{2} - b^{2}[/tex]
a = [tex]\sqrt{41^{2} -(4\sqrt{41})^{2} }[/tex] = [tex]\sqrt{1681 - 656 }[/tex] = [tex]\sqrt{1025}[/tex] = [tex]5\sqrt{41}[/tex]
The opposite side is [tex]5\sqrt{41}[/tex] , as sine is negative (-) in the IV quadrant so the value will be [tex]-5\sqrt{41}[/tex].
So we know that Sine is the ratio of the Opposite side to the hypotenuse, which can be written as:
sineθ = [tex]\frac{Opposite}{Hypotenuse}[/tex]
sineθ = [tex]-\frac{5\sqrt{41} }{41}[/tex]

Therefore T(1,0,0) = (1,0,0)
(1,0,0) is 1st column of matrix of T
T(0,1,0) = (1,1,0)
(1,1,0) is 2nd column of matrix of T
T(0,0,1) = (1,1,0)
(1,1,0) is 3rd column of matrix of T
Therefore Matrix representation of T with respect to standard basis of IR^3 is
A = 1,1,1 0,1,1 0,0,0
2. Nullspace of T = kennel T
KerT = {(x,y,z)E IR^3/T(x,y,z,) = (0,0,0)}
KerT = {(x,y,z)E IR^3/(x+y+z, y+z,0) = (0,0,0)}

KerT = {(x,y,x) EIR^3/x = 0, y = -2}
KerT = {(0,-z,z)}
KerT = {z(0,-1,1)} = Multiple of T
As it contains only one linear independent rectors = nullity = 1
3. Range T = {T(x,y,z)/(x,y,x) EIR^3}

T(1,0,0) = (1,0,0)
(1,0,0) = a(1,0,0) + b(1,1,0) + c(1,1,1)
(1,0,0) = (a+b+c, b+c, c)
a+b+c = 1, b+c = 0, c = 0
b = 0, a = 1
Therefore above of a,b,c gives first column matrix
Now,
T(1,1,0) = (2,1,0)
consider (2,1,0) = a(1,0,0) + b(1,1,0) + c(1,1,1)
(2,1,0) = (a+b+c, b+c, c)
a+b+c = 2, b+c = 1, c = 0
b = 1, a = 1
Therefore above values of a,b,c gives 2nd column of matrix
Now,
T(1,1,1) = (3,2,0)
(3,2,0) = a(1,0,0) + b(1,1,0) + c(1,1,1)
(3,2,0) = (a+b+c, b+c, c)
a+b+c = 3, b+c = 2, c = 0
b = 2, a = 1
Therefore above values of a,b,c gives 3rd column of matrix

The given equations are
12q + 3r = 15 ….. (1)
- 4q - 4r = - 44 ……. (2)
Multiply equation (2) by 3, we get
- 12q - 12r = - 132 ….. (3)
Now by adding the equations (1) and (3), we get
3r - 12r = 15 - 132
- 9r = - 117
r = 117/9 = 13
By Substituting the value of r in equation (2), we get
- 4q - 4 (13) = - 44
- 4q - 52 = - 44
- 4q = - 44 + 52
- 4q = 8
q = - 2

What is the intermediate step in the form ( x + a ) 2 = b (x+a) 2 =b as a result of completing the square for the following equation?.
The intermediate step in the form ( x + a ) ^2 = b (x+a) 2 =b as a result of completing the square of x² - 4x = 45 is (x- 2)² = 49
How to determine the intermediate step?
The equation is given as:
x² - 4x = 45
Take the coefficient of x
k = -4
Divide by 2
k/2 = -2
Square both sides
(k/2)^2 = 4
Add 4 to both sides of x² - 4x = 45
x² - 4x + 4= 45 + 4
This gives
x² - 4x + 4= 49
Express as perfect square
(x- 2)² = 49
Hence, the intermediate step of x² - 4x = 45 is (x- 2)² = 49

why will a probability curve always give a probability of zero for a point estimate on a continuous random variable
Probability curve always give a probability of zero for a point estimate on a continuous random variable.
A probability distribution in which the random variable x can take on any value because there are infinite values that x could assume, the probability of x taking on any one specific value is zero.
we often speak in ranges of values (p(x>0) = .50). The normal distribution is one example of a continuous distribution. The probability that X falls between two values (a and b) equals the integral (area under the curve) from a to b.
Density function:
f(x) = P(a≤x≤b) = ∫f(x).dx ≥ 0.

What is the outlier in a data set 5th grade?.
What is the domain of a square root?.
The domain of the square root function is x≥0.
What is a function?
Any relation in which each input has exactly one output is referred to as a function. To put it another way, the function outputs one value exactly for each input value. Because one is mapped to two different values, the graph above depicts a relation rather than a function. But if one were instead mapped to a single value, the relation above would become a function. Furthermore, output values could be identical to input values.
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
The square root function's purpose must now be considered. The positive number that results in the input after being squared is returned as the principal root or output. Since y will be bigger than or equal to 0, we may be certain of that.
To find out a perfect square we need to find out square root is an integer.
Hence, The domain of the square root function is x≥0.
