Answer:
The only one that works is 48:30
Step-by-step explanation:
You can't divide 24 by anything to get 16, nor 15 to get 10
5:3 means 15 was divided by 3, 24 divided by 3 is 8
Alright, so let's figure this out...
The total miles driven was 81. Let's go ahead and see how many times 81 goes into 4!
<em>81 / 4 = 20.25</em>
Her average was 20.25 mph. =)
x-26=57
+ 26 26
__________
x=83
Alana started with 83 tickets.
Is this what you mean?
I hope so! :)
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
Answer:
Step-by-step explanation:
Hello!
To easily identify these items you have to ask yourself the following questions:
1)
Who I want to study?
Answer: Workers age 16 or older from Arizona
The population of the study is all the experimental units in existence, in this case
<u>Population:</u> Workers age 16 or older from Arizona
The sample is a part of the population of interest, normally representative of the population and randomly selected, that the researcher uses to study.
In this case, the<u> sample </u>taken is: 5000 Arizona workers age 16 or older
The individual is defined by each experimental unit that conforms the sample, in this case
<u>Individual: </u>One Arizona worker age 16 or older.
2)
What do I want to study?
Answer: The percentage of people who use the train to get to work
The variable of interest is the characteristic that the researcher will measure in each experimental unit:
<u>Variable:</u> "The percentage of Arizona workers age 16 or older who use the train to get to work"
I hope this helps!
