Answer: P-value = 0.1235604
We do not reject the null hypothesis .
Step-by-step explanation:
We know that when the obtained p-value is less than the significance level () then we reject the null hypothesis otherwise we do not reject null hypothesis .
Given : Two-tailed test with test statistic and
The p-value for the given test static (two-tailed)
So , we do not reject the null hypothesis .
Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
Answer:
July has the highest attendance.
Step-by-step explanation:
The attendances are expressed in scientific notation where the second term, 10^x, means 10 to the xth power. For example 10^1 = 10, 10^2 = 10*10 = 100 and so on.
Looking at the table, July's attendance has the highest power, 10^6 while other months only have 10^5. So July has the highest attendance.
6 + (10 x 2) = 26 = (12+1)*2
The water level starts at 800. Then, with each year, we add a meter. It means that after t years we add exactly t meters.
So, at any given time t, the water level will be
