You design a new app for cell phones. Your revenue for x downloads is given by f(x) = 3x Your profit
Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x  ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

<u><em>means</em></u>

p=90\% f\left( x\right)  -20

<u><em>means</em></u>

<u><em></em></u>p=\frac{90}{100} \times f\left( x\right)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=2.7x -20

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223

Tom goes to the book fair where paperback books are $3 and hardback books are $5.50. Travis
astra-53 [7]

Answer:

1:  50 - (3(3) + 5.5(4))=x

2: okay so we know how much books are brought and how much each cost.

In this case paper backs are 3 dollars each and cost 3 dollars each. So 3 (3) is 9 dollars. The next scenario are hardbacks which are 5.50 each and Tom brought 4 of them. So that makes it 5.5(4) which is 22 dollars. So the total would be 9+22 which is 31 dollars. The question asks for change from a 50 dollar bill which you subtract and 50-31=19

The change would be 19 dollars

Determine whether or not the following question can be considered as a statistical question.
Naddika [18.5K]

The situation would come as follows: "Does Andrew make more money than Laura?"

The question can only be answered with a yes or no. Which does not generate any statistics because they are characterized by having an inherent variability in the data used to answer the question. And in this question there is no variability since if you earn more money or not because they are focused on itself, there is a positive or negative side and from there there is no variation.

Therefore NOT a statistical question.
