If you make all the denomenators 12 and fix the numerators add all the numerators together and divide it by 12 to get your answer.
8/12 + 7/12 + 5/12 + 10/12 = 30/12
30/12 = 2 1/2 pizza
Answer:
H0: μ = 8.3 hours
Ha: μ > 8.3 hours
We need to remember that a type of error II if the error associated when we NO reject the null hypothesis when actually the alternative hypothesis is true. And is also known as false negative. The best answer for this case would be:
D. The manufacturer will decide the mean battery life is 8.3 hours when in fact it is greater than 8.3 hours.
Since we are FAILING to reject the null hypothesis when the true mean is actually higher than the value specified
Step-by-step explanation:
For this case we want to determine if mean running time has increased as a result of the new change so then the system of hypothesis are given by:
Note: we assume that the value to check in order to be consistent with the options is 8.3
H0: μ = 8.3 hours
Ha: μ > 8.3 hours

Answer:
65.7
Step-by-step explanation:
Given the population of West Algebra can be modeled by the equation
P = 30. 1.04^T
If T is the number of years since 2000 and P is the population in millions, in 2020, T = 2020 - 2000 = 20
Substitute T = 20 into the expression and get T
P = 30. 1.04^20
P = 30(2.1911)
P = 65.73
Hence the amount of people that will be there in 2020 is 65.7million people
Answer:
I think it is 1
Step-by-step explanation:
I am sorry if it is not correct
Infinity and negative infinity, absolute value it's always more than 0
