Answer:
equation: y = 32000 - 2000x
0 = 32000
1 = 30000
2 = 28000
3 = 26000
4 = 24000
Step-by-step explanation:
Answer:
Step-by-step explanation:
Data given and notation
represent the sample mean given
represent the population standard deviation
sample size
represent the value that we want to test
t would represent the statistic (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean for the gasoline prices is lower than 1.25, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
If we analyze the size for the sample is > 30 but we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
Calculate the statistic
We can replace in formula (1) the info given like this:
Answer:
16
Step-by-step explanation:
To get the next number just mulitply by 4
4*4=16
( just to make sure we're correct)
16*4=64
64*4=256
256*4=1024
1024*4=4096
True.
Since

,

and the solutions are decreasing functions.
