Answer:
Step-by-step explanation:
hello :
2x+3y=6
1) x = 0 : 2(0)+3y=6 means 3y=6 so : y=6/3 = 2
2) y = 0 : 2x+3(0)=6 means 2x=6 so : y=6/2 = 3
3) x = - 3 : 2(-3)+3y=6 means 3y=12 so : y=12/3 = 4

Answer:
z = -2.13
The standardized score for the state of Colorado is negative and this means the score is smaller than the mean.
Step-by-step explanation:
The above question can be solved using z score.
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado is negative and this indicates that the score is below or smaller than the mean.
