Answer:
The number that would represent a sample statistic of a population but not a parameter is:
O A. Neither 500 nor 50,000
Step-by-step explanation:
The reason behind this is that a parameter has to follow a certain guideline because it needs to fulfill a rule to be considered one. There has to be a correlation, so if we have no clear establishment the number can't be a parameter. Thus, 500 would be the minimum 1% to be considered as a parameter and 50,000 the whole universe of the population. They keep a correlation, therefore any number but they would be a sample statistic.
Answer: -600 and 1600 were invested into the two accounts.
Step-by-step explanation:
x = amount invested in the first account.
y = amount invested in the second account.
You start off with this equation


Subtract both sides by y.

Subsitude 1000 - x for x for the second equation.

Use the distributive property to solve for y.




Subsitude -600 for y in the first equation and solve for x.


-600 and 1600 were invested into the two accounts.
