33.33%
Step-by-step explanation:
Answer:
33.3333%
explaination
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form. Now we can see that our fraction is 33.333333333333/100, which means that 25/75 as a percentage is 33.3333%

The equation(24x^2 + 25x - 47)/(ax--2) = -8x - 3 - 53/(ax--2) is true of all values of x≠2/a where a is a constant. What is the value of a?
Please help me there is no multiple choice :(
Answer:
-3
Step-by-step explanation:
The fastest way to solve this problem is to multiply each side of the given equation by in order to get rid of the fraction. After you do this you should have:
Then multiply [tex](-8x-3)[/tex] and [tex](ax-2)[/tex] using FOIL:
[tex]24^2+25x-47=-8ax^2-3ax+16x+6-53[/tex]
Then reduce on the right side of the equation:
[tex]24x^2+25x-47=-8ax^2-3ax+16x-47[/tex]
Because the coefficients of the [tex]x^2[/tex] term have to be equal on both sides of the equation, reduce from [tex]-8a=24[/tex] to [tex]a = -3[/tex] by dividing both sides by [tex]-8[/tex].
in a game the player wins if he rolls a 4 on a number cube if the numbered cube is rolled 24 times then what is the reasonable prediction for the number of unsuccesful rolls
If you roll a numbered cube once, your chance of getting a 4 is 1/6. If you roll twice, your chance of getting a 4 is 2/12. If you roll three times, your chance of getting a 4 is 3/18. You see the pattern here? Try it yourself and see if you can get it! If you can't understand it, let me know and I'll give you the answer!

Answer: The mass of the remaining element = 1.1 grams .
Step-by-step explanation:
Exponential equation of decay: [tex]y=A(1-r)^x[/tex] ...(i), where A = intial value , r= rate of decay in decimal , x= time.
As per given :
Initial mass : A= 140 grams
Rate of decay : r= 21.6% per minute= 0.216 per minute.
x= 20 minutes
Substitute values in (i) , we get
[tex]y=140(1-0.216)^20\\\\=140(0.784)^2^0=1.077579422[/tex]
Hence, the mass of the remaining element = 1.1 grams .
Ms. Brockman wants to take her class on a trip to either the nature center or the zoo. The nature center charges $4 per student, plus $95 for a 1-hour naturalist program. The zoo charges $6 per student plus $75 for a 1-hour guided tour. Find the number of students where the two field trips would have the same cost.
Step-by-step explanation:
ten students.
4(10)+95=135
6(10)+75=135
4x+95=6x+75
-75+4x+95=6x+75-75
4x+20=6x
-4x+4x+20=6x-4x
20=2x
(20=2x)/2
x=10
Answer:
10 students
Step-by-step explanation:
4(10)+95=135
6(10)+75=135
4x+95=6x+75
-75+4x+95=6x+75-75
4x+20=6x
-4x+4x+20=6x-4x
20=2x

Jean wants to invest a gift of $4,250 in the stock market. A broker suggests two companies, Solar Solutions (SOLR) and Frontline Medical (FLMD). He provides the probabilities for an annual return on $4,250 based on their historical gains: SOLR: 50% chance of $1,000 gain, 35% chance of $200 gain, 15% chance of $600 loss FLMD: 80% chance of $750 gain, 20% chance of $100 loss Which is the best analysis of these investments?
Answer:
the answer is the question with $580 in it please correct me if im wrong
Step-by-step explanation:
Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.
How to calculate the expected return?The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:
50% chance of $1,000 gain: 0.5 x $1,000 = $500
35% chance of $200 gain: 0.35 x $200 = $70
15% chance of $600 loss: 0.15 x -$600 = -$90
Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.
The expected return on FLMD is calculated in the same way:
80% chance of $750 gain: 0.8 x $750 = $600
20% chance of $100 loss: 0.2 x -$100 = -$20
Therefore, the expected return on FLMD is $600 - $20 = $580.
Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.
The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

Answer:
11. D
12. $7,000
Step-by-step explanation:
For the first one, $.10 is added for every mile over 50. So if someone drives 51 miles, $.10 will be added. If they drive 52 miles, $.20 will be added. In the last of the options, the initial $100 is added to the $.10 multiplied by x - 50. x represents the number of miles that he drove. x - 50 is the number of 0.10 dollars that are added to the $100.
For the second question, her sales were over $3,500, so we're looking at the second slot in the table.
The equation E = $2,500 + 0.1s + 0.2(s - 3500) tells us that her total earnings are $2,500 plus 10% of her sales plus 20% of her sales minus 20% of 3500.
To solve for s:
E = $2,500 + 0.1s + 0.2(s - 3500)
Distribute 0.2 over the terms in parentheses.
E = 2,500 + 0.1s + 0.2s - 700
Then, combine like terms.
E = 1800 + 0.3s
We know her earnings were $3,900 so we can substitute that into the equation.
3900 = 1800 + 0.3s
Subtract 1800 from both sides.
2100 = 0.3s
Divide both sides by 0.3
7000 = s
So s, the value of her total monthly sales, is $7,000
