Find the number of years the annuity will last if it pays 300 per year.
The number of years the annuity will last if it pays $300 per year is 18 years.
What is an annuity?An annuity is an investment that pays the investor a fixed periodic amount for many years in the future.
The annuity payment may be monthly or yearly, as the case may be.
An online finance calculator can compute the annual payment (annuity).
I/Y (Interest per year) = 7%
PV (Present Value) = $3,000
PMT (Periodic Payment) = $-300
FV (Future Value) = $0
Results:
N = 17.795
Sum of all periodic payments = $-5,338.44
Total Interest $2,338.44
Thus, for an annuity with a present value of $3,000, earning 7% per annum and paying $300 per year will last almost 18 years.

Write a quadratic function in standard form that models the table. X -5 -3 -1 13 y 0 12 12 16 12 0
Answer:
First, we need to find the quadratic function that models the given table. We know that a quadratic function has the form: y = ax^2 + bx + c where a, b, and c are constants to be determined. To find these constants, we need to use the values in the table. When x = -5, y = 0, we get: 0 = a(-5)^2 + b(-5) + c 0 = 25a - 5b + c When x = -3, y = 12, we get: 12 = a(-3)^2 + b(-3) + c 12 = 9a - 3b + c When x = -1, y = 12, we get: 12 = a(-1)^2 + b(-1) + c 12 = a - b
an investor has rs 30000 that he wants to invest in bank deposits, equity shares and unit trust. in view of the risk involved in buying equity shares he wants to invest an amount in equity share is equals to 20% of his total investment in bank deposits and unit trust. Because of certain tax exemptions available to him , he would like to maintain the ratio of 3:2 between investment in bank deposits and unit trust. determine the amount he would invest in each of the three forms of investment using inverse matrix method
The investor should invest Rs 12,000 in bank deposits, Rs 8,000 in a unit trust, and Rs 10,000 in equity shares.
The investor has a total of Rs 30,000 to invest in bank deposits, equity shares, and unit trusts. According to the given conditions, the investment in equity shares should be 20% of the total investment in bank deposits and unit trusts. Also, the ratio between investment in bank deposits and unit trust should be 3:2.
Let x be the investment in bank deposits, y be the investment in a unit trust, and z be the investment in equity shares. Based on the given conditions, we can create the following system of equations:
x + y + z = 30,000 (total investment)
z = 0.2(x + y) (equity shares condition)
x/y = 3/2 (ratio condition)
Using the inverse matrix method, we can rewrite these equations as a matrix equation:
|1 1 1| |x| |30,000|
|0.2 0.2 -1| |y| = |0 |
|3/2 -1 0 | |z| |0 |
To solve this matrix equation, we can compute the inverse of the coefficient matrix and multiply it with the constant matrix:
A = |1 1 1|
|0.2 0.2 -1|
|3/2 -1 0 |
A_inv = |2/5 -1/5 -1/5|
|-3/2 1/2 1/2|
|5/2 1/2 -3/2|
Multiplying A_inv with the constant matrix, we get:
|x| |12,000|
|y| = |8,000 |
|z| |10,000|
So, the investor should invest Rs 12,000 in bank deposits, Rs 8,000 in a unit trust, and Rs 10,000 in equity shares.

the population full-time equivalent number of students (ftes) at lake tahoe community college for 2005-2006 through 2010-2011 was given in an updated report. the data are reported here. year 2005-06 2006-07 2007-08 2008-09 2009-10 2010-11 total ftes 1,585 1,690 1,735 1,935 2,021 1,890 calculate the mean, median, standard deviation, the first quartile, the third quartile and the iqr. round to one decimal place. mean _____
median _____
Standard deviation ______
first quartile _____
third quartile ____
IQR _____
The correct answer for the required values is 1825.5, 1,812.5, 165.2, 1,690, 1,935, and 245 respectively.
To find the mean, median, standard deviation, first quartile, third quartile, and interquartile range (IQR) of the full-time equivalent number of students (FTES) at Lake Tahoe Community College for the given years, we can solve it using the following formulas for various aspects:
Mean: μ = (Σx)/n
Median: Middle value of the data set
Standard deviation: σ = sqrt[Σ(x-μ)²/n]
First quartile (Q1): Median of the lower half of the data set
Third quartile (Q3): Median of the upper half of the data set
IQR: Q3 - Q1
Year FTES
2005-06 1,585
2006-07 1,690
2007-08 1,735
2008-09 1,935
2009-10 2,021
2010-11 1,890
1. μ = (Σx)/n = (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890)/6 = 1,825.2
Therefore the mean is 1,825.2
2. To find the median, arrange the data in ascending order:
1,585, 1,690, 1,735, 1,890, 1,935, 2,021
Since there are an even number of values, the median is the average of the two middle values, which are 1,812.5 and 1,812.5. So, the median is:
Median = (1,812.5 + 1,812.5)/2 = 1,812.5
3. σ = sqrt[Σ(x-μ)²/n]
= sqrt[((1,585-1,825.2)² + (1,690-1,825.2)² + (1,735-1,825.2)² + (1,935-1,825.2)² + (2,021-1,825.2)² + (1,890-1,825.2)²)/6]
= 165.2
4. To find the first quartile (Q1), find the median of the lower half of the data set, which consists of the values 1,585, 1,690, and 1,735.
Since there are an odd number of values, the median is the middle value, which is 1,690. Therefore, Q1 = 1,690.
5. To find the third quartile (Q3), we need to find the median of the upper half of the data set, which consists of the values 1,890, 1,935, and 2,021.
Since there are an odd number of values, the median is the middle value, which is 1,935. Therefore, Q3 = 1,935
6. IQR = Q3 - Q1
Substituting the calculated values in the equation
IQR = 1935 - 1690

Answer:
Rounded to the nearest integer, the test had 18 problems in all.
Step-by-step explanation:
Given that a student missed 10 problems on an English test and received a grade of 44%, if all the problems were of equal value, to determine how many problems were on the test the following calculation must be performed:
100 - 44 = 56
56 = 10
100 = X
100 x 10/56 = X
1,000 / 56 = X
17.85 = X

Darrel loaned his friend $2,500 to help him with his business. If his friend pays Darrel back in 1 year with 15% simple interest, how much will he owe Darrel altogether
Based on simple interest, the solution to the question is that his friend will ultimately owe Darrel $2,875.
What is Simple interest?A loan or investment's interest can be calculated using simple interest using the principal, interest rate, and duration of the transaction. Because it just considers the original principal and does not account for any compounded interest, it is known as "simple" interest.
Darrel will be indebted to his friend for the following sum if he lends him $2,500 and receives repayment with 15% simple interest after a year:
Interest = Principal x Rate x Time
Interest = $2,500 x 0.15 x 1
Interest = $375
Thus, the total sum his friend will be required to pay Darrel is:
Total amount = Principal + Interest
Total amount = $2,500 + $375
Total amount = $2,875
Thus, the total amount his friend owes Darrel is $2,875.

An 8-sided number cube is rolled 4000 times. The number 2 appeared 200 times. Determine the theoretical and experimental probability of rolling a 2 in order to determine the fairness of the number cube. Drag values or words to the boxes to correctly complete the statements.
Theoretical Probability of rolling a 2= 1/20
Experimental Probability of rolling a 2 = 1/20
Theoretical probability of rolling a 2:
The theoretical probability of an event is the ratio of the number of favourable outcomes to the total number of possible outcomes. Since there are 8 sides to the cube, the total number of possible outcomes is 8. Since the number 2 appeared 200 times out of 4000 rolls, the number of favorable outcomes is 200. Therefore, the theoretical probability of rolling a 2 is:
Theoretical Probability of rolling a 2 = Number of favourable outcomes / Total number of possible outcomes = 200/4000 = 1/20
Experimental probability of rolling a 2:
The experimental probability of an event is the ratio of the number of times the event occurred to the total number of trials. In this case, the event is rolling a 2, which occurred 200 times out of 4000 rolls.
Therefore, the experimental probability of rolling a 2 is:
Experimental Probability of rolling a 2 = Number of times the event occurred / Total number of trials = 200/4000 = 1/20
Comparing theoretical and experimental probability:
If the cube is fair, we would expect the theoretical probability and the experimental probability to be similar. In this case, both probabilities are 1/20, which means that the cube appears to be fair. However, we would need to conduct more trials to be more confident in our conclusion.

write an equation for a line passing through the point (4,a) and (-5,a)
Answer
The equation of the line is
y = a
Explanation
The general form of the equation in point-slope form is
y - y₁ = m (x - x₁)
where
y = y-coordinate of a point on the line.
y₁ = This refers to the y-coordinate of a given point on the line
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
x₁ = x-coordinate of the given point on the line
So, we just need to calculate the slope and use one of the points to calculate this equation of the line
For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as
\(Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1}\)For this question,
(x₁, y₁) and (x₂, y₂) are (4, a) and (-5, a)
\(\text{Slope = }\frac{a-a}{-5-4}=\frac{0}{-9}=0\)Using (4, a) as the point,
Recall,
y - y₁ = m (x - x₁)
m = 0
(x₁, y₁) = (4, a)
x₁ = 4
y₁ = a
y - y₁ = m (x - x₁)
y - a = 0 (x - 4)
y - a = 0
y = 0 + a
y = a

Which correctly shows the substitution step for the system?
y = x - 4
-4x - 6y = -16
O x-4 = -4x-6y
-4(x-4) - 6y = -16
O-4x-6(x-4) = -16
6y = x - 4
The solution to the system of equations is x = 4 and y = 0. In summary, the correct substitution step for the system is: -4x - 6(x - 4) = -16 .C answer is correct
To solve the given system of equations:
1) y = x - 4
2) -4x - 6y = -16
We can use the substitution method to eliminate one variable and solve for the other.
Step 1: Solve the first equation (1) for y in terms of x.
y = x - 4
Step 2: Substitute the expression for y from equation (1) into equation (2).
-4x - 6(x - 4) = -16
Step 3: Simplify and solve for x.
-4x - 6x + 24 = -16
-10x + 24 = -16
-10x = -16 - 24
-10x = -40
x = -40 / -10
x = 4
Step 4: Substitute the value of x back into equation (1) to solve for y.
y = 4 - 4
y = 0
Therefore, the solution to the system of equations is x = 4 and y = 0.
In summary, the correct substitution step for the system is:
-4x - 6(x - 4) = -16
By substituting the expression for y from equation (1) into equation (2) and simplifying, we obtain the equation -4x - 6y = -16, which can be further solved to find the values of x and y. C answer is correct

Antonio needs to score at least 111 points in his next game to reach his goal of an average of at least 100 points per game.
What are basic arithmetic operations?
Basic arithmetic operations are fundamental mathematical calculations that involve manipulating numerical values using a set of basic operations.
To find out how many points Antonio needs to score in his next game to reach an average of at least 100 points per game, we can use the following formula:
Total points needed = (number of games + 1) × average score goal - total points scored so far
In this case, Antonio has played 5 games, so the number of games he will have played after his next game is 6. His goal is an average of 100 points per game, so his average score goal is 100. The total points he has scored so far is:
105 + 95 + 97 + 82 + 110 = 489
Substituting these values into the formula, we get:
Total points needed = (6) × (100) - 489
Total points needed = 600 - 489
Total points needed = 111
Hence, Antonio needs to score at least 111 points in his next game to reach his goal of an average of at least 100 points per game.
