The actual end-of-year payment or present value of this ordinary annuity is equal to $1,482.
How to calculate the actual end-of-year payment?For the rate of interest, we have:
Rate of interest, r = APR/12
Rate of interest, r = 0.12/12
Rate of interest, r = 0.01
Next, we would calculate the present value of this ordinary annuity by using this formula:
Present value, PV = [P ÷ [1 - (1 + r)^{-n}]/r]
Where:
r is the interest rate.P is the principal.n is the number of times compounded.Substituting the given parameters into the formula, we have;
Present value, PV = 4,500 ÷ ((1 - (1 + 0.12)^(-4))/(0.12))
Present value, PV = 4,500 ÷ ((1 - (1.12)^(-4))/(0.12))
Present value, PV = 4,500 ÷ ((1 - 0.635518078)/(0.12))
Present value, PV = 4,500 ÷ ((0.364481922)/(0.12))
Present value, PV = 4,500/3.0373
Present value, PV = $1,481.58 ≈ $1,482.

Find the missing number in the following puzzle.
The average weight of a population of manatees is unknown. A random sample of manatees selected from the population yields a sample mean of x¯=880.3 pounds. Assume the sampling distribution of the mean has a standard deviation of σx¯=10.4 pounds. Use the Empirical Rule to construct a 68% confidence interval for the true population mean weight.
The confidence interval that we have for the population mean is given as [869.9 , 890.7]
How to solve for the confidence intervalThe confidence interval is the range of values that, if you repeated your experiment or resampled the population in the same manner, you would anticipate your estimate to fall within a specific proportion of the time.
We have the following data that we have to solve this problem with
The mean = x¯=880.3 pounds
The standard deviation = 10.4 pounds.
The confidence interval = 68%
To get the confidence interval for the true mean of the population weight we would have
mean ± standard deviation
880.3 ± 10.4
The interval would be written out as
880.3 - 10.4 and 880.3 + 10.4
the confidence interval =
[869.9 , 890.7]

A die is continuously rolled until the total sum of all rolls exceeds 150 What is the probability that at least 40 rolls are necessary?
The probability that at least 40 rolls are necessary is 4/15.
What is probability?
Probability shows the likelihood of an event happening. it can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1
Probability P=no. outcomes/total no. of the possible outcomes

What transformation takes the graph of f(z) - 4z +9 to the graph of g (z) = 4x+7?
translation 2 units right
translation 2 units left
translation 2 units down
translation 2 units up
The linear function g(z) = 4 · z + 7 is the result of applying the transformation rule g(z) = f(z) - 2 (Translation two units down) on the linear function f(z) = 4 · z + 9 . (Correct choice: C)
What transformation rule is used to transform a given function?
In this problem we find a linear function that is modified into another linear function by a transformation rule. We need to find if the function is modified by a horizontal translation, a vertical translation or a combined translation, that is, a combination of horizontal and vertical translations.
Horizontal translation
g(x) = f(x - k), where k > 0 for a translation in + x direction.
Vertical translation
g(x) = f(x) + k, where k > 0 for a translation in + y direction.
After a quick inspection, we notice that linear function f(z) = 4 · z + 9 is transformed into g(z) = 4 · z + 7 by using vertical translation 2 units down. Then, we find the following transformation formula:

Using simple mathematical operations, David's overall loss is -5.8.
What do we mean by mathematical operations?Calculating a value while using operands as well as a math operator is known as a mathematical "operation."The supplied operands or integers must comply with a specified set of standards pertaining to the symbol of the math operator.A rule that outlines the appropriate procedures to follow when examining a mathematical equation is known as the order of operations.You can recall the PEMDAS actions parenthesis, exponents, multiplication, dividing (from Left to Right), adding, and subtracting in this order (from left to right).So, the overall gain/loss of David is:

9. The sum of two numbers is 130 and their difference is 34. Let x be the first number and y be the second
number. Set up a system of equations and use the elimination method to find the numbers. You must
show your work.
Using the system of equations and use the elimination method the two numbers are 82 and 48.
What is the elimination method?
To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are equal.
Here, we
let the first number = x
let the second number = y
according to the given conditions:
x + y = 130 ........(1)
x - y = 34 .........(2)
Using the elimination method we add both equations (1) and (2) and we get
2x = 164
x = 164/2 = 82
Now, we substitute the value of x in eq (1) and we get
82 + y = 130
y = 130-82
y = 48
Hence, using the system of equations and use the elimination method the two numbers are 82 and 48.
