A probability experiment is conducted wich of these can not be considered a probability of an outcome: a) 0.222 b) 8.2% c) 0.0234 d) 122.96% e) 5/3 f) 0.45%
122.96% and 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. Correct option is d and e.
In probability, the probability of an outcome must be a value between 0 and 1, inclusive. Therefore, any value less than 0 or greater than 1 cannot be considered a probability of an outcome.
Let's check each option:
a) 0.222 - This is a valid probability since it is between 0 and 1.
b) 8.2% - This can be converted to a decimal as 0.082, which is a valid probability since it is between 0 and 1.
c) 0.0234 - This is a valid probability since it is between 0 and 1.
d) 122.96% - This can be converted to a decimal as 1.2296, which is not a valid probability since it is greater than 1.
e) 5/3 - This can be simplified to approximately 1.6667, which is not a valid probability since it is greater than 1.
f) 0.45% - This can be converted to a decimal as 0.0045, which is a valid probability since it is between 0 and 1.
Therefore, options (d) 122.96% and (e) 5/3 cannot be considered probabilities of outcomes in a probability experiment because they are greater than 1. The other options are valid probabilities as they fall within the range of 0 to 1, inclusive.

Five years ago the population of Australia was 23.13 million. It has grown by 870 000. What is the population of Australia now?
The current population of Australia is 24 million.
It is given to us that the initial population was 23.13 million and the population 5 year later has grown by 870000 or 0.87 million. Thus to find the current population we simply need to add the initial population and the growth that has happened in 5 years. This gives us:
[tex]Current\ population = 23.13\ million + 0.87\ million = 24\ million[/tex]
Thus, the current population of Australia is 24 million.

Madeline sold $167 worth of items at a garage sale and then received her $232 paycheck. Estimate how much money she now has by rounding to the nearest ten first and then adding the rounded numbers.
Madeline has approximately $400 after rounding her garage sale earnings and paycheck to the nearest ten and adding them together.
The question involves estimating the total amount of money Madeline has after selling items at a garage sale and receiving her paycheck. To estimate the total amount, we need to round each amount to the nearest ten and then add the rounded numbers together.
First, round $167 to the nearest ten, which is $170.
Next, round $232 to the nearest ten, which is $230.
Finally, add the rounded numbers: $170 + $230 = $400.

S = √3*73.5 /4.5=7 (Khufu’s pyramid)
The volume of Khafre’s pyramid is about 9/10 the volume of Khufu’s pyramid. If Kristina wants to make the second model pyramid so its volume is 9/10 the volume of the first model pyramid, what volume should she make the second model pyramid?
This goes with the other questions! if you need information i can get that for you!
Also, could you work it out!
3/6 should b you answer answer
Final answer:
The volume will be of 6.3 for the second model.
Explanation:
The student is asked to calculate the volume of the second model pyramid, Khafre's pyramid, which is 9/10 the volume of the first model, Khufu's pyramid. The student has already calculated that, for Khufu's pyramid, S = √3*73.5/4.5=7. To find the volume Kristina should make the second model, we simply multiply the volume of the first model by 9/10.
Although the question does not provide the exact volume of the first model, we will assume the value of S given is the volume of Khufu's pyramid model. Therefore, the volume of Khafre's pyramid model should be 7 * (9/10) = 6.3.
This result is based on the proportion given between the two pyramids' volumes and is a straightforward calculation of this proportion.

Joel is looking at costs for using a gym. He could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit. How many visits would he have to make each month to make the $50 per month unlimited use option the cheapest one?
Answer:
First choice is cheaper.
Step-by-step explanation:
Joel could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit.
Let the monthly visits be x
We can define this as :
[tex]12+4x> 50[/tex]
[tex]4x >50-12[/tex]
[tex]4x >38[/tex]
[tex]x> 9.5[/tex]
So, x can be greater than 9.5 means 10.
[tex]4(10)+12>50[/tex]
[tex]52 > 50[/tex]
Comparing both we can say that the first choice is cheaper.
