Answer:
The z value is - 2.88
Step-by-step explanation:
The formula of the z-score of a population is z = (x¯ - μ)/(σ/
)
The given in the problem is:
- μ = 121
- σ = 21
- x¯ = 112.35
- n = 49
Let us substitute all of these values in the rule above
Simplify up and down
z = - 2.883333
Round it to 2 decimal places
∴ z = - 2.88
The z value is - 2.88
A number raised<span> to a </span>negative power<span> is equal to 1 divided by the </span>number raised<span> to the same </span>power<span> but positive
</span>therefore
[-1/2]^-3-----------> [-2]^3 =-8
the answer is [-1/2]<span>^-3
