URGENT!!!! Find the y-intercept of the line that passes through the points (-3, 7) and (3, −9).
Answer:
\(m = \frac{ - 9 - 7}{3 - ( - 3)} = \frac{ - 16}{6} = - \frac{8}{3} \)
\(7 = - \frac{8}{3} ( - 3) + b\)
\(7 = 8 + b\)
\(b = - 1\)
\(y = - \frac{8}{3} x - 1\)
The y-intercept is -1.
A college is hosting an invention camp for middle school students. One of the 1,200 students who attend will receive a laptop at the
end of the camp. The college wants to place notecards labeled with each student's name in a bin and draw a winner from the bin. The
bin will hold only 200 notecards though.
Which method assures both that the college can use the bin for the drawing and that each student has a fair chance of winning?
Place notecards labeled with the names of the oldest 200 students into the bin. Randomly select the winner from the bin.
O Place notecards labeled with the names of the first 200 students who registered for the camp into the bin. Randomly
select the winner from the bin.
Randomly assign the 1,200 students to 10 equal-sized groups. Then randomly select 4 of the groups and place their
names in the bin. Randomly select the winner from the bin.
Randomly assign the 1,200 students to 6 equal-sized groups. Then select one of the groups and place their names in the
bin. Randomly select the winner from the bin.
Answer: Randomly assign the 1,200 students to 6 equal-sized groups. Then select one of the groups and place their names in the bin. Randomly select the winner from the bin.
Step-by-step explanation:
First, let us see how many bins we will need in total.
1,200 students / 200 notecards per bin = 6 bins
Now, the first two options do not give all students a fair chance of winning. They are not our answer.
The last two have a different number of groups. Looking at the calculation we did earlier, we will need 6 equal-sized groups. This means our answer is the last option.
Nancy went to the mall on Saturday to buy clothes. She paid $14.95 on pants and
$4.05 on a jacket with a $20 bill. How much money did Nancy get in change?
Answer:
$1.00
Step-by-step explanation:
Total cost = $14.95 + $4.05 = $19.00
Change = $20.00 - $19.00 = $1.00
A 12 1/2 mile stretch of road needs repaving . A company bids on the repaving project saying they could replace 2 1/4 miles of road per week. How many weeks will the company take to completely replace the stretch of road?
2 1/4 miles => 1 week
1 mile => 1 ÷ 9/4
( 9/4 is an improper fraction of 2 1/4 )
12 1/2 miles => ( 1 ÷ 9/4 ) × 25/2
= 50/9
= 5 5/9 weeks
( 25/2 is an improper fraction of 12 1/2 )
Therefore, it will take 5 5/9 weeks for the company to replace the stretch of road.
( you can round it off to 6 weeks if the qn specify to give to the nearest whole number )
A customer at an electronics store opened a store credit card to purchase a computer for $1,800. The store put the entire purchase on the credit card with an APR of 17.99%. The customer
pays $125 per month until the balance is paid off. Determine the total amount of interest paid.
A spreadsheet was used to calculate the correct answer. Your answer may vary slightly depending on the technology used.
O $188.09
O $295.01
O $243.11
O $182.45
The last row of the table will show the total interest paid, which is approximately $243.11.
The correct option is C.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
To calculate the total interest paid,
we need to first find out how many months it will take to pay off the entire balance.
We can use the following formula to calculate the number of months:
N = -log(1-(r×b/p))/log(1+r)
where N is the number of months, r is the monthly interest rate (which is the annual percentage rate divided by 12), b is the balance, and p is the payment.
In this case,
r = 0.1799/12 = 0.01499 (monthly interest rate), b = $1,800, and p = $125.
Plugging these values into the formula, we get:
N = -log(1-(0.01499 × 1800/125))/log(1+0.01499) ≈ 16.24
So it will take about 16.24 months to pay off the entire balance.
Using a spreadsheet, we can create a table with the following columns:
Month: 1 to 16
Balance: starting with $1,800 and decreasing by $125 each month
Interest: calculated as the monthly interest rate times the balance
Payment: $125
Total Interest: calculated as the sum of the interest for all previous months
The last row of the table will show the total interest paid, which is approximately $243.11.
Therefore, the value is (C) $243.11.

$255.2
Explanation:
If the tax rate is 7.05%, the state sales tax on a $23200 car is calculated as:
23,200 x 7.05% = 23,200 x 7.05 / 100 = $1635.6
Then, the final cost will be the initial cost plus the sales tax, so
$23200 + $1635.6 = $24835.6
In the same way, if the sales tax rate is 5.95%, the state sales tax will be
23,200 x 5.95% = 23,200 x 5.95 / 100 = $1380.4
And the final cost will be
$23200 + $1380.4 = $24580.4
Therefore, the money saved by driving to Morgan country will be
$24835.6 - $24580.4 = $255.2
So, the answers are:
$1635.6
$24835.6
$1380.4
$24580.4

you and a friend have created a carnival game for your classmates. you plan to charge $1 for each time a student plays, and the payout for a win is $5. according to your calculations, the probability of a win is .05 what is your expected value for this game?
Answer:
The expected value for this game is -$0.75, indicating that, on average, players would expect to lose $0.75 per game.
Step-by-step explanation:
Expected Value = (Probability of Winning * Payout for Win) - Cost of Playing
In this case:
Probability of Winning = 0.05
Payout for Win = $5
Cost of Playing = $1
Expected Value = (0.05 * $5) - $1
Expected Value = $0.25 - $1
Expected Value = -$0.75

Solve for x.
2/5+x=1
Answer:
Hello... im exhausted but ill solve it i guess
To solve for x in the equation 2/5 + x = 1, we can follow these steps:
Subtract 2/5 from both sides of the equation to isolate the x term:
2/5 + x - 2/5 = 1 - 2/5
This simplifies to:
x = 1 - 2/5
Find a common denominator for 1 and 2/5, which is 5:
x = 5/5 - 2/5
Subtract 2/5 from 5/5:
x = 3/5
So, the solution for x in the given equation is x = 3/5.

animal shelter. Which two equations
could be used to find the number of
treats each dog gets?
A
(B)
18+6=24 and 24 - 6 = 18
18 6 3 and 6 X 3 = 18
18
D6÷3=2 and 6 ÷ 2 = 3
18 1 and 1 X 18 = 18
The two equations that could be used to find the number of
treats each dog gets is B) 18 / 6 = 3 and 6 X 3 = 18 So, the option B is the correct answer
What is an equation?
Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't limit the generality.
A condition on a variable is what an equation in algebra is. It can only be satisfied if the variable has a specific value. That indicates that only the value of x = 9 may satisfy the equation 2x - 5 = 13.
There are several sorts of equations as well, including:
Linear equations
Quadratic equations
cube-based equations
Differential equations
Parametric equations
As Tolen has 18 dog treats and he has 6 dogs to feed so each dog will get 3 treats i.e. (18 / 6 = 3) or we can there are 6 dogs and Tolen has 18 dog treats to finish so he will give 3 dog treats to each dog i.e.
(6 X 3 = 18)

Which statement describes the graph of the system of equations?
Answer:
Are there any choices?..
The correct statement the describes the equation is The lines intersect at (1, 0) and the lines are parallel.
x - y = 1.............equation 1
y - x = 1.............equation 2
Add equations (1) and (2):
(x - y) + (y - x) = 1 + 1
Simplifying
0 = 2
Since 0 = 2, the system is inconsistent, meaning there is no solution. The lines represented by the equations are parallel and will never intersect.
