Answer:
For this case we want to determine if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than .66 (a;ternative hypothesis) and then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
And the estimated proportion for this case would be:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem
For this case we want to determine if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than .66 (a;ternative hypothesis) and then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
And the estimated proportion for this case would be:
Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is
-----> equation B
The slope of the line B is
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
The answer is a, when multiplying numbers with the same base you add their exponents
Answer:
Wat, don't you make up a problem for this one?
Step-by-step explanation:
Like search up on google a problem that's happening in the real world, but that the Coronavirus :p
and then explain how you solve it with math-
Or make up a problem then solve the problem?
Idk if this helped-
But if it did, uH-
Have a nice day!
