Given:
Population mean,  μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.

By definition, the z-score is
z = (x - μ)/σ
   = (11 - 10)/1.5
   = 0.667

Answer: 0.667

Explain why functions with the property f(–x) = –f(x) are called odd functions and functions with the property f(–x) = f(x) are
anastassius [24]

Answer:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis and The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin .

Step-by-step explanation:

The functions with the property f(–x) =f(x) are called even functions because they symmetric about the y-axis . In other words these functions usually take a form x^2 ,x^4 ,x^6 ,x^8 etc . However ,there are other functions that behave like that too, such as cos(x).An even exponent does not always make an even function, for example (x+1)^2 is not an even function .

The functions with the property f(–x) = -f(x) are called odd because these function are symmetric about the origin . In other words they are called odd because of the functions like x, x^3 ,x^5 ,x^7, etc .but there are other functions that behave like that, too, such sin(x) .but an odd exponent does not always make an odd function, for example x3+1 is not an odd function.

Whats a function rule for this:<br> 7 less than three fifths of b is a
Elanso [62]
(3/5)b - 7 = a

Remember "of" means to multiply. Less than means subtraction: 7 less than means -7.
