Jim likes to day-trade on the internet. On a good day, he averages a $1100 gain. On a bad day, he averages a $900 loss. Suppose that he has good days 25% of the time, bad days 35% of he time, and the rest of the time he breaks even

Answer:
Jim will incur a loss of $2,400 in the 60-day period under review
Step-by-step explanation:
The question is incomplete. However, one assumption was made in attempting the question, ie, the timeframe was set at 60-days:
Jim likes to day-trade on the internet. On a good day, he averages a $1100 gain. On a bad day, he averages a $900 loss. Suppose that he has good days 25% of the time, bad days 35% of he time, and the rest of the time he breaks even, *what is Jim's balance after a 60-day period* ?
Solution
From the question, given period X = 60 days, and;
Jim's streak is as follows: 0.25X Profit : 0.35X Loss : (100 - (0.25+0.35) Even
Jim's streak = 0.25*60 : 0.35*60 : 0.4*60 = 15 + 21 + 24 (days)
15 profitable days = 15 * $1100 = $16,500
21 bad days 21*$900 = $18,900
24 even days = 24*$0 = $0
Balance after 60 days = $16500+(-$18900)+$0 = $16500-$18900 = -$2400
Final answer:
The expected daily value for Jim's day-trading hobby is -$40, meaning he should expect to lose $40 per day. Over three weeks of trading every weekday, this amounts to a total expected loss of -$600.
Explanation:
The subject of this question is expected value, a concept in probability and statistics, which essentially means the average result of a large number of trials in an experiment. In Jim's case, three possible outcomes are concerning his day-trading hobby: a good day ($1100 gain), a bad day ($900 loss), and a break-even day ($0 gain or loss).
Here's how we calculate:
- A good day: 25% * $1100 = $275
- A bad day: -35% * $900 = -$315
- A break-even day: 40% * $0 = $0
The expected value of one day of trading for Jim is thus: $275 - $315 + $0 = -$40.
If Jim trades every weekday for three weeks (that is, 15 days), we can multiply the daily expected value by 15. So, Jim should expect to lose $40 * 15 = -$600 over three weeks.

Answers
Answer: D. $28,908.50
Step-by-step explanation:
Given: Cost price of car= $26,500
Cost of options= $725
Therefore, the total cost=$26,500+ $725=$27225
As there is a 6% sales tax in his state .
⇒ Tax amount = 6% of Total cost
⇒Tax amount=$1,633.5
Combine $50 licence, registration fee and tax amount to the total cost , we get
Total cost=$27225+$1,633.5+$50
∴Total cost=$28,908.5

25% = 0.25
0.25 • 35.00 = 8.75
This means there is a $8.75 discount, or $8.75 off in other words.
All that's left to do is subtract the discount amount from the original price.
35.00 - 8.75 = 26.25
So the price of the jeans with the sale is $26.25.
*multiply 35 × .25 (move decimal over to the left twice so that it is not a "percentage")
*35 × .25 = 8.75 (now since 25% is 1/4th of 100% you can multiply 8.75 by 4 to make sure you get the full 100% price of $35.00)
*now you know 8.75 is 25% of $35.00
*subtract 8.75 (25%) from 35 (100%)
*35 - 8.75 = 26.25
*june will pay $26.25 with the 25% sale off of the $35.00 original price of the jeans.

P is distance from vertex to directix
remember to subtract P from the y value of the vertex (p-k) and that y value is the directix, y=p-k
nut
ok so one way is to just graph them on a graphing utility
remember if the graph opens up, then the directix is below that
or we can convert to 4P(y-k)=(x-h)^2 form where P is distance from directix
I will only convert the 1st one fully, you should be able to do the rest
1. y=-x^2+3x+8
multiply both sides by -1 since we don't like the x^2 term negative
-y=x^2-3x-8
add8 to both sides
-y+8=x^2-3x
take 1/2 of linear coeficient and square it and add to both sides
-3/2=-1.5
(-1.5)^2=2.25
-y+10.25=x^2-3x+2.25
factor perfect square
-y+10.25=(x-1.5)^2
force undistribute -1 in left side
(-1)(y-10.25)=something, we don't care anymore for now
factor out a 4 in -1
4(-1/4)(y-10.25)
k=10.25
p=-1/4=-0.25
directix=k-p=10.25-(-0.25)=10.5
directix is y=10.5
basically completee the square with x and find P by force factoring a 4 out
2. directix: y=-1.75
3. directix: y=1.5
4. directix: y=17.25
