Evgesh-ka [11]

Answer:

Hello! I am also having trouble in algebra! From what I can see so far this is what the problem should look like...

Step-by-step explanation:

A. Yes, it s a linear function because it matches the equation y=mx+b

B. The domain is 1, 2, 3 , 4, and 5. This is because there are 5 services you can choose from. The domain is discrete because you can't have half a service.

C. Because I'm also doing this book (I'm in Algebra 1 in 8th grade), I'm also just learning this! So sorry, but I don't know how to solve this one either... can someone please help?

Thanks! Also, just a tip, if you're having trouble ever again go to slader.com where they have all the answers to any textbook. They also have really good explanations! However, for this one, I didn't understand it on slader so I came on here! Good luck and if anyone can help with C that would be much appreciated.

Answer:


Step-by-step explanation:

cross multiply, \frac{4x + 3(x-1)}{12}\\\\

\frac{4x+3x-3}{12}\\  \\

\frac{7x-3}{12} = 2 + x

7x -3 = 12(2+x)\\\\7x - 3 = 24 + 12x\\\\12x - 7x = -3 - 24\\\\5x = -27 \\\\x = \frac{-27}{5} = -5.4

A freelancer, who specializes in digital marketing, is interested in the average amount of money small businesses spend on pay p
Lapatulllka [165]

Answer:

The freelancer needs to calculate the value of the observed test statistic - average annual pay per click advertising cost - in order to compare with the critical value.

Step-by-step explanation:

His hypothesis test will be:

Null hypothesis: Average Annual Pay per click advertising cost is still less than 3300 dollars

(Note: the null hypothesis is the fact that the experimenter wishes to refute)

Alternative Hypothesis: Average annual pay per click advertising cost is now above 3300 dollars

(Alternative hypothesis is the fact that the experimenter expects to be true)

The Critical Value is a cutoff value for which if the value of the observed test statistic exceeds it, the null hypothesis is refuted and if the value of the observed test statistic is below it, the null hypothesis remains.

That is, either the freelancer accepts that the cost has not risen or he accepts that the cost has risen.
