Answer:
Pop in 1990 = 81 million rats
Pop in 2005 = 127 million rats
Step-by-step explanation:
Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.
The rat population in 2005 is given by the formula when t = 15
This is: approximately 127 million rats.
Answer:
Step-by-step explanation:
3t² - t
3(4²) - 4
3(16) - 4
48 - 4
44

Answer:
Step-by-step explanation:
-let denote the population mean in grams.
-The claim under investigation is that the machine is underfilling the bags.
-The investigator intends to determine whether or not the population mean is less than 430 grams.
#The stated hypotheses are:
The null hypothesis(mean gram of the bags is greater or equal to 430g):
-Alternative hypothesis is the population mean is less than 430g:
