Answers
Answer:What was done from the first to the second equation was that the fraction was simplified. 126 and 32 have a common factors of 2.
126/32=(63*2)/(16*2)
The 2s in the top and bottom can cancel out, leaving the fraction 63/16.
In addition, since there are x terms on the top and bottom, they cancelled out as well.
x/x^3=1/x^2
This leaves an x^2 term on the bottom.
Thus, if a is 16, and b is 2, you will have an equivalent form of the fraction.

3.9y + 3 - 2.9y=
anybody know?!
Answers
Answer:
= y + 3
Step-by-step explanation:
Group:
= 3.9y - 2.9y + 3
Add elements together:
= y + 3
Arrange equation so that like terms are next to each other
3.9y - 2.9y + 3
Subtract.
1y + 3
Since 1y and 3 are not like terms, we cannot add them.
Therefore, 1y + 3 is the answer.
You can also write y +3.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answers
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75
14.25/4.75 = 3
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Step-by-step explanation:
A P E X
All options could change a taxpayer's adjusted gross income when filing a federal income tax return.
Options A, B, C, and D are the correct answers.
What is taxpayer-adjusted gross income?
Taxpayer-adjusted gross income (AGI) is a person's gross income (all income from various sources such as wages, self-employment, interest, dividends, and capital gains) minus certain deductions (such as contributions to a traditional IRA, alimony payments, and student loan interest).
We have,
- Medical and dental expenses are deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.
- Contributions to an IRA may be deductible, which would lower the taxpayer's adjusted gross income.
- Casualty and theft losses may be deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.
- Charitable contributions made are deductible if the taxpayer itemizes deductions, which would lower the taxpayer's adjusted gross income.
Thus,
All of the above could change a taxpayer's adjusted gross income when filing a federal income tax return.

Distributed all out will equal: 9i-13j
We can then go ahead and use Pythagorean therm to find the magnitude: V = Square root of (9)^2 + (-13)^2

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

What is the number that has a value 10 times the value of 0.009? Please Explain.
Answers
Answer:
Step-by-step explanation:
I don’t know
Answer:
0.09
Step-by-step explanation:
From what I'm understanding you have to use powers of 10. Here's how they work:
All you do is move the decimal point, I know that may sound weird but let me explain.
When we are working with powers of 10 you just multiply the number by 10.
10 x 0.009
Now instead of having to type that into a calculator, or working it out, you can just move the decimal point to the right or the left.
Here's how I remember it:
Multiplying- move it to the right so the number can get bigger
Dividing- move it to the left so the number gets smaller
The number of zeros (0) you have after the one determines how many times you move the decimal point.
100- move the decimal point twice
100000- move the decimal point 5 times
In this case you are multiplying and moving the decimal point to the right once. There is one zero in the number and the problem asks you to multiply.
0.009
= 0.09
You move the decimal point over once.
Hope this helps!!!
