Answer: P = 0
Step-by-step explanation:
Solve for p by simplifying both sides of the equation, the isolating the variable.
-2p + 10p = 7p, P will equal 0.

You are dividing a number (x) by three and then subtracting 1 like this. (x/3)-1
(-3,-3) is your answer please give brainliest!
Answer:
: p= .78
: p > .78
Step-by-step explanation:
Determining the null and alternate hypotheses of a scenario require several components. The first is if one should use p or mu. This depends on if they are assessing a proportion or a mean, since the publisher states a percentage, you know that they are asking for a proportion, and therefore should use p. Next, they will need to assess what value to use for the hypothesis statements, here only .78 is provided and therefore should be used in both. Finally, it is time to add in the comparison symbols, the null hypothesis always uses an equals sign so it therefore becomes:
: p= .78
The alternate hypothesis then needs to consider if the researchers claim that the new proportion is greater, fewer, or different. In this case it is greater as they think that the ownership is above 78%, so a greater than sign would be used and the final statement would be:
: p > .78
Answer:
total earning is $64.80
Step-by-step explanation:
Price of one work = $18.00
Payment by owner = 1/4 of $18.00
= 18/4
= $4.50
Earning by tip = 20% of $18.00 = 20/100 x18 = 3.60
Total earning from one work = $4.50+$3.60
= $ 8.10
Earning from 8 tips = 8x8.10
= $64.80
