Answer:
Step-by-step explanation:
-Given the population mean is 
and the standard deviation is 
, we calculate the z-scores using the formula:
#The z-score for 1910 can be calculated as:
#The z-score for 1230can be calculated as:
#The z-score for 2190 is calculated as follows:
#The z-score for 1380 is calculated as:
Answer:
Hence, the value of y is undefined.
Step-by-step explanation
from the property, log_a (b) = (log(a))/log(b).
The value log (-7) was not defined. So, the entire log value also not defined.
Hence, the value of y is undefined.
Answer:no
Step-by-step explanation:
Answer:
The answer would be a=2.
Step-by-step explanation:
Since both sides of the equation are being multiplied by b then you would divide both of them by B. This will just remove the B from the equation entirely and leave you with a=2. I hope that this was helpful.
