Which of the following is an irrational number?
I am Lyosha [343]

Hi!

<h3>An irrational number is a number that cannot be written as a ratio or a fraction. </h3><h3>Let's go through each answer. </h3>
  • A. √0.036

= 0.18973666...

<u>This is irrational, because it repeats forever.</u>

  • B. 7.2525

<u>This is rational, because 2525 repeats in a pattern.</u>

  • C. √1

= 1

<u>This is rational. (1/1)</u>

  • D. 10

<u>This is rational (10/1)</u>

<h2>The answer is A. √0.036.</h2>

Hope this helps! :)

(b) About what percentage of the states (out of 51) seem to have close to 800 licensed drivers per 1000 residents? (Round your a
Rina8888 [55]
This question uses a dotplot graph from which you have to extract the information.

I have attached the dotplot graph in a pdf file. You can open the file to see the graph if you do not have it.

The graph shows with dots (they use this mark +) the 51 states. Every dot means that one state has the number of license drivers per 1000 residents given by the line. For example, you can see that just above the mark of 700 therer are two dots, meaning that two states have 700 licensed drivers per 1000 residents.

Now you can see that there are 5 dots "close" the 800 mark.

That means that 5 out of 51 states "seem to have close to 800 licensed drivers per 1000 residents".

The percentage is calculated as [5/51]*100 = 9.804 %, which rounded to one decimal place is 9.8%.

Answer: 9.8%

<h2>Answer:</h2>

Our functions are:

f(x) = -5x + 12\\g(x) = -\frac{3}{2}x + 4\\

To solve this, we must use the expression g(-10) - f(3).

-\frac{3}{2}(-10) + 12 - [-5(3)] + 12\\\\15 + 12 - [-5(3)] + 12\\\\15 + 12 - (-15) + 12\\\\27 - (-15) + 12\\\\42 + 12\\\\54

The value of the expression g(-10) - f(3) is <em>15</em>.
