-10x-10x-10=-1000. Another way to think of that is the cube root of -1000 is -10.
Answer:
x>10
Step-by-step explanation:
What this is saying is the variable "x" is any number.
To then make it an inequality im using the greater than symbol (not to be confused with greater than or equal to symbol)
So this means if x= "any number" and has a greater than symbol.
"any number" is greater than 10.
Answer:20
Step-by-step explanation: Cause 60-20=40
Answer:
Z - score = 2.83
Step-by-step explanation:
Given the following :
Number of samples (N) = 60
Sample mean (x) = 41.9mg
Population mean (μ) = 40mg
Population standard deviation (sd) = 5.2
Using the relation :
Z = (x - μ) / (sd / √N)
Z = (41.9 - 40) / (5.2 / √60)
Z = 1.9 / (5.2 / 7.7459666)
Z = 1.9 / 0.6713171
Z = 2.8302570
Therefore, the z-score = 2.83
