Radical 6x^2 multiplied by radical 18x^2
1 answer:
Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.
Well, I'm going to assume that radical = square root
So, if you have two square root functions, you can multiply the numbers within the square root, so you now have , which I'm not sure if you want it simplified or not

Answer:
(I assume you have to do this on some kind of online graphing program.)
Step-by-step explanation:
Plot a point at (0, -3) because that is the y-intercept. Plot the second point at (3, 1). Once you hit “done” your graph should look similar to the one I attached a picture of. *rotatre the picture so the grey is on the bottom*
Answer:
a) p=0.39, where p the parameter of interest represent the true proportion of adults that would erase all their personal information online if they could
b) Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
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".
On this case the claim that they want to test is: "The true proportion of adults that would erase all their personal information online if they could is 0.39 or 39%". So we want to check if the population proportion is different from 0.39 or 0.39%, so this needs to be on the alternative hypothesis and on the null hypothesis we need to have the complement of the alternative hypothesis.
Part a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information.
p=0.39, where p the parameter of interest represent the true proportion of adults that would erase all their personal information online if they could
Part b. Identify the null and alternative hypotheses.
Null hypothesis:
And for the alternative hypothesis we have
Alternative hypothesis:
