I believe it is B, because going down would be negative, and it is subtracting 6.
Answer:
m= 1/2
b= -4/3
Step-by-step explanation:
An equation in standard form is in the format of
Y=mx+b
Answer: C. Equal to
Step-by-step explanation:
The standard deviation is written as:
Sx = √( ∑(xₙ - x)^2/(n-1))
Where xₙ are the values of the data set, n is the number of data points and x is the mean of the data set.
Now, if we add a constant c to all the terms in our data set we will have:
(i will use the ' to denote the transformed data)
xₙ' are now xₙ + c.
And the new mean will be:
x' = ( (x₁ + c) + (x₂ + c) + .... + (xₙ + c))/n = (c*n + (x₁ + x₂ + ..))/n = c + (x₁ + x₂ +...)/n
x' = c + x
Then the new standard deviation will be:
Sx' =√( ∑(xₙ' - x')^2/(n-1))
Sx' = √( ∑((xₙ+c) - (x +c))^2/(n-1)) = √( ∑(xₙ - x)^2/(n-1)) = Sx
So the standard deviation does not change.
The correct option is C.
Answer:
The pattern: 1 3 5 7 9 11 13 15 ..........
Step-by-step explanation:
f(n) = 2n + 1
F(0) = 1
f(1) = 2 * 1 + 1 =3
f(2) = 2 * 2 + 1 =5
f(3) = 2 * 3 + 1 = 7
The pattern: 1 3 5 7 9 11 13 15 ..........
