Six students need to raise $2050 for a trip. They have a starting balance of $58.
The equation below shows the amount of money (m) each student would need to
contribute if the remaining balance were divided equally among the students.
58+6m-2050
Which graph is closest to showing the actual dollar amount each
student should contribute?
Answer:
Money divided: $332
Correct graph: Graph 2
Step-by-step explanation:
First we know that the total amount raised is $2050 and that the starting balance is $58
So we can make a expression saying 6m + 58 = 2050
2050-58 = 1992
so we know that 6m = $1992
to work out m, we divide 1992 by 6.
1992/6=m=$332
Graph 2 is the correct graph as Graph 1 shows $290, Graph 3 shows $340 and Graph 4 shows $370 and we want to be as close to the original amount which is $332.

Egbert wants to establish a fund for his grandchild's college education. What lump sum must he deposit at a 7% annual interest rate, compounded quarterly, in order to have $40,000 in the fund at the end of 10 years? Fill in the values, plug into the formula, use algebra and your calculator to get the result. Round to the nearest cent.
Egbert must deposit $19,602.52 as a lump sum in order to have $40,000 in the fund at the end of 10 years.
To calculate the required lump sum deposit, we can use the formula for compound interest:
A = P\((1+r/n)^{nt}\)
Where:
A = the future value (desired amount in the fund) = $40,000
P = the initial principal (lump sum deposit we need to find)
r = the annual interest rate in decimal form = 7% = 0.07
n = the number of compounding periods per year = 4 (quarterly compounding)
t = the number of years = 10
Plugging in these values, the formula becomes:
$40,000 = P\((1+(0.07/4)^{(4*10)}\)
Simplifying further:
$40,000 = P\((1.0175)^{40}\)
Now we can solve for P by dividing both sides of the equation by
P = $40,000 /\((1.0175)^{40}\)
Using a calculator to evaluate the expression, we find:
P ≈ $19,602.52
Therefore, Egbert must deposit approximately $19,602.52 as a lump sum in order to have $40,000 in the fund at the end of 10 years.

A couple plans to purchase a house. The bank requires a 20% down payment on the $240,000 house. The couple will finance the rest of the cost with a fixed- rate mortgage at 8.5% annual interest with monthly payments over 30 years.
Complete the parts below. Do not round any intermediate computations. Round your final answers to the nearest cent if necessary. If necessary, refer to the list of financial formulas.
(a) Find the required down payment.
(b) Find the amount of the mortgage.
(c) Find the monthly payment.
(A) The required down payment is $48,000.
(B) The amount of the mortgage is $192,000.
(C) Monthly payment = $192,000 * (0.085/12) * (1 + (0.085/12))^(3012) / (((1 + (0.085/12))^(3012)) - 1)
(a) To find the required down payment, we need to calculate 20% of the house price.
Down payment = 20% of $240,000
Down payment = 0.2 * $240,000
Down payment = $48,000
The required down payment is $48,000.
(b) The amount of the mortgage is equal to the total cost of the house minus the down payment.
Mortgage amount = Total cost of the house - Down payment
Mortgage amount = $240,000 - $48,000
Mortgage amount = $192,000
The amount of the mortgage is $192,000.
(c) To find the monthly payment for the mortgage, we can use the formula for the monthly payment on a fixed-rate mortgage:
Monthly payment = P * r * (1 + r)^n / ((1 + r)^n - 1)
Where:
P = Principal amount (mortgage amount)
r = Monthly interest rate (8.5% annual interest divided by 12 months and converted to a decimal)
n = Total number of monthly payments (30 years multiplied by 12 months)
Monthly payment = $192,000 * (0.085/12) * (1 + (0.085/12))^(3012) / (((1 + (0.085/12))^(3012)) - 1)
Using this formula and performing the calculation will give you the monthly payment amount.

Find the zeros of the function in the interval (-2 pie, 2 pie). f(x) = 3 cos x
Answer:
Roots are -π/2 and π/2
Step-by-step explanation:
\({ \bf{f(x) = 3 \cos(x) }}\)
when x is -2π:
\({ \sf{f( - 2\pi) = 3 \cos( - 2\pi) }} \\ { \sf{ = 3}}\)
hence -2π is not a zero of the function
when x is 2π:
\({ \sf{f(2\pi) = 3 \cos(2\pi) }} \\ { \sf{ = 3}}\)
hence 2π is not a zero of the function
when x is π/2:
\({ \sf{f( \frac{\pi}{2}) = 3 \cos( \frac{\pi}{2} ) }} \\ { \sf{ = 0}}\)
Hence ±π/2 is the zero of the function.

How to simplify this:
Arcctg(tg(x) )
The expression arcctg(tg(x)) simplifies to arcctg(tan(x)).
To simplify the expression arcctg(tg(x)), we can apply trigonometric identities and properties.
The function arcctg(x) is the inverse cotangent function, which is the angle whose cotangent is x. Similarly, tg(x) represents the tangent function.
First, let's simplify the expression inside the arcctg function, which is tg(x):
tg(x) = sin(x) / cos(x)
Now, we can substitute this value into the original expression:
arcctg(tg(x)) = arcctg(sin(x) / cos(x))
Using the property of inverse trigonometric functions, we can rewrite this as:
arcctg(sin(x) / cos(x)) = arcctg(1 / tan(x))
Now, we can simplify further using the identity:
1 / tan(x) = cot(x)
Therefore:
arcctg(1 / tan(x)) = arcctg(cot(x))
Using another identity, we know that the cotangent function is the reciprocal of the tangent function:
cot(x) = 1 / tan(x)
Therefore, we can simplify the expression to:
arcctg(cot(x)) = arcctg(1 / tan(x)) = arcctg(tan(x))
Finally, we arrive at the simplified expression:
arcctg(tg(x)) = arcctg(tan(x))

A teacher designs a test so a student who studies will pass 90% of the time, but a student who does not study will pass 11% of the time. A certain student studies for 85% of the tests taken. On a given test, what is the probability that student passes?
Answer:
probability that student passes = 0.7815
Step-by-step explanation:
Given:
Student studies = 85% = 0.85
Student not study = 11% = 0.11
Student who pass = 90% = 0.90
Computation:
P(student not pass) = 1 - 0.85
P(student not pass) = 0.15
probability that student passes = P(Student studies)(Student who pass) + P(Student not study)(student not pass)
probability that student passes = (0.85)(0.90) + (0.15)(0.11)
probability that student passes = 0.765 + 0.0165
probability that student passes = 0.7815
Using the percentages given, it is found that there is a 0.7815 = 78.15% probability that student passes.
The percentages associated with passing the test are given by:
90% of 85%(student studies for the test).11% of 15%(student does not study for the test).Hence, adding these percentages:
\(p = 0.9(0.85) + 0.11(0.15) = 0.7815\)
0.7815 x 100% = 78.15%

These values have an average of 8. What is the average distance of those values from that average of 8? 0 4 8 10 18
what is the average distance
The average distance of the values 0, 4, 8, 10, and 18 from their mean of 8 is 4.8.
The average distance of the values 0, 4, 8, 10, and 18 from their mean of 8 is 6.4.
Here's how to calculate it:Step-by-step explanation:
The mean or average of a set of numbers is obtained by adding all the numbers and then dividing by the number of numbers.
Thus, the mean of 0, 4, 8, 10, and 18 is:(0+4+8+10+18)/5 = 8
So, the mean of these values is 8.
The average distance of the values from their mean is also called the mean deviation or average deviation.
To calculate the mean deviation, we first need to calculate the deviation of each value from the mean.
Deviation is the difference between a value and the mean.
The deviations for these values are:-8, -4, 0, 2, 10
Now, we calculate the average of these deviations by adding them up and dividing by the number of values.
The sum of deviations is:-8 + (-4) + 0 + 2 + 10 = 0
The number of values is 5.So, the mean deviation or average deviation is:0/5 = 0
Therefore, the average distance of the values from their mean of 8 is 0.
But, if we want to find the average distance in absolute terms, we need to take the absolute values of the deviations. The absolute values of the deviations are:8, 4, 0, 2, 10
Now, we calculate the average of these absolute deviations by adding them up and dividing by the number of values. The sum of absolute deviations is:8 + 4 + 0 + 2 + 10 = 24
The number of values is 5.So, the mean deviation or average deviation is:

The circle below has center O, and its radius is 3 ft. Given that m AOB = 160°, find the length of the arc ADB and the area of the shaded region. Give exact answers in terms of , and be sure to include the correct units in your answer.
Answer:
The length of the arc ADB is (8/3)π ft and the area of the shaded region is 4.5 ft^2 - 4π ft^2.
Step-by-step explanation:
In the given circle with center O and radius 3 ft, let's consider the angle AOB, which is given as 160°. We need to find the length of the arc ADB and the area of the shaded region.
To find the length of the arc ADB, we can use the formula for the circumference of a circle and calculate the fraction of the total circumference represented by the angle AOB.
The circumference of a circle is given by 2πr, where r is the radius. In this case, the radius is 3 ft. Therefore, the total circumference is 2π(3) = 6π ft.
To find the length of the arc ADB, we calculate the fraction of the total circumference represented by the angle AOB. Since the angle AOB is 160° out of 360°, the length of the arc ADB is (160/360) * 6π ft = (4/9) * 6π ft = (8/3)π ft.
Next, to find the area of the shaded region, we need to subtract the area of the sector AOB from the area of triangle AOB. The area of the sector AOB is (160/360) * π * (3)^2 = (4/9) * 9π = 4π ft^2. The area of triangle AOB is (1/2) * 3 * 3 = 4.5 ft^2.
Therefore, the area of the shaded region is 4.5 ft^2 - 4π ft^2 = 4.5 ft^2 - 4π ft^2.
In summary, the length of the arc ADB is (8/3)π ft and the area of the shaded region is 4.5 ft^2 - 4π ft^2.

During your morning workout, you run for 20 seconds for every 3 seconds you sprint. Determine the constant of proportionality for the ratio between the number of seconds you run and the number of seconds you sprint.
Answer:
Constant of proportionality; k = 20/3
Step-by-step explanation:
Let running be A and sprinting be B.
Now, we are told that you run 20 seconds for every 3 seconds you sprint.
This means that is directly proportional to B and written as; A ∝ B.
Now, constant of proportionality is simply the ratio between 2 quantities that are directly proportional.
Thus, A = kB
Where k is the constant of proportionality
Plugging in the values of A and B we are given, we have;
20 = 3k
Divide both sides by 3 to get;
k = 20/3
