Answer:
A. 3.31227766..., irrational
Step-by-step explanation:
We have been given two numbers. We are asked to find sum of given numbers and classify the type of number after addition.
[tex]\frac{3}{20}+\sqrt{10}[/tex]
[tex]0.15+3.1622776601683793[/tex]
[tex]3.3122776601683793[/tex]
We can see that [tex]\frac{3}{20}[/tex] is a rational number, while [tex]\sqrt{10}[/tex] is an irrational number as its digits are repeating infinitely after decimal.
We know that sum of a rational and irrational number is irrational, therefore the sum of given numbers is irrational and option A is the correct choice.

Which of the equations below is correct to compute the present value of the cash flows at 8% interest?
a. p=1000(p/a,i,8)−150(p/g,i,8)+ 150(p/g, i, 4)(p/f, i, 4)
b. p=400(p/a,i,8)+600(p/a,i,5)− 150(p/g, i, 4)
c. p=150(p/g,i,4)+850(p/a,i,4)+ 400(p/a, i, 4)(p/f, i, 4)?
The correct equation to compute present value of cash flows at 8% interest is C. P = 150(P/G, į, 4) + 850(P/A, i, 4) + 400(P/A, i, 4)(P/F, i, 4).
So, option C is correct answer choice.
To calculate the present value of the cash flows in the image, we can use the formula for the present value of an annuity and the formula for the present value of a lump sum.
Here's the step-by-step calculation for the present value of the cash flows at 8% interest:
(1) Identify the annuity and the lump sum:
The cash flows from year 4 to year 8 represent an annuity of $400 per year for 5 years.
The cash flows in years 1, 2, and 3 represent lump sums of $1000, $850, and $700, respectively.
(2) Calculate the present value of the annuity:
We can use the formula for the present value of an ordinary annuity:
PV = PMT × (1 - 1 / (1 + i)^n) / i
Where:
PMT = the annuity payment ($400 per year)
i = the interest rate (8% or 0.08)
n = the number of periods (5 years)
Plugging in the values, we get:
PV = 400 × (1 - 1 / (1 + 0.08)⁵) / 0.08
PV ≈ $1558.94
(3) Calculate the present value of each lump sum:
We can use the formula for the present value of a lump sum:
PV = FV / (1 + i)^n
Where:
FV = the future value (the cash flow amount)
i = the interest rate (8% or 0.08)
n = the number of periods from the present time to the cash flow (1, 2, and 3 years for the lump sums)
Calculate the present value of each lump sum:
PV (year 1) = 1000 / (1 + 0.08)¹ ≈ $925.93
PV (year 2) = 850 / (1 + 0.08)² ≈ $762.09
PV (year 3) = 700 / (1 + 0.08)³ ≈ $613.91
(4) Add the present values of the annuity and the lump sums.
The total present value is the sum of the present value of the annuity and the present values of the lump sums.
Total PV = PV (annuity) + PV (year 1) + PV (year 2) + PV (year 3)
Total PV ≈ $1558.94 + $925.93 + $762.09 + $613.91
Total PV ≈ $3860.87
Complete and correct question:
Which of the equations below is correct to compute the present value of the cash flows at 8% interest?
A. P= 1000(P/A, i, 8) 150(P/G, i, 8) + 150(P/G, i, 4)(P/F, i, 4)
B. P = 400(P/A, i, 8) + 600(P/A, į, 5) 150(P/G, į, 4)
C. P = 150(P/G, į, 4) + 850(P/A, i, 4) + 400(P/A, i, 4)(P/F, i, 4)

Suppose that we have the least squares regression line y = 3 + 2x and that the sum of the squares of the errors (sse) for this line is 13,712. what can be said about the sum of the squares of the errors (sse) for this data set and the line y = 3 + 2.5x?
The question involves linear regression and the sum of squared errors (SSE), which quantify the total deviation of the response values from the fitted line. If y=3 + 2x is the best-fit line, then the SSE for the line y=3 + 2.5x would be greater than 13,712.
Explanation:The question involves the concept of linear regression and the sum of squared errors (SSE). The SSE of a regression line is quantified by the difference between the observed and predicted values of the dependent variable, each squared and added together. These show how well the regression line fits the data.
In the context of this question, you're given the SSE for the line y = 3 + 2x. However, you're asked about the SSE for the line y = 3 + 2.5x. Since the slope of this new line is steeper, the predicted y-values will be different from those from the original line and generally farther from the actual data points. Therefore, it can be said that if the line y = 3 + 2x is the best-fit line, then the SSE for the line y = 3 + 2.5x would be greater than 13,712.
Error in prediction is generally greater when we move away from the least-squares regression line. Thus the SSE provides a quantifiable way to determine the line that best fits the data.

Answer:
Step-by-step explanation:
If x is a binomial random variable with n=10 and p=0.8, what is the probability that x is equal to 4?
The probability that x is equal to 4 in a binomial distribution with n=10 and p=0.8 is 0.006048.
Explanation:To find the probability that x is equal to 4 in a binomial distribution with n=10 and p=0.8, we can use the probability mass function (PMF) of the binomial distribution.
The PMF is given by: P(x) = (n choose x) * p^x * (1-p)^(n-x)
Substituting the given values, we have: P(4) = (10 choose 4) * 0.8^4 * 0.2^6 = 0.006048

Kerianne paints landscapes, and in late 2018 placed four paintings with a retail price of $160 each in the Holmstrom Gallery. Kerianne’s arrangement with Holmstrom is that Holmstrom will earn a 10% commission on paintings sold to gallery patrons. As of December 31, 2018, one painting had been sold by Holmstrom to gallery patrons.
Holmstrom earned a commission of $16 for the painting sold to gallery patrons.
Explanation:The subject of this question is Mathematics and the grade level is High School.
To calculate the commission earned by Holmstrom for the painting sold, we can use the formula: commission = (retail price * commission rate) / 100. In this case, the retail price of the painting is $160 and the commission rate is 10%, so the commission earned by Holmstrom for the painting sold is $16.
Therefore, Holmstrom earned a commission of $16 for the painting sold to gallery patrons.

The revenue Kerianne should recognize in 2024 with respect to these four paintings is $216.
The retail price for each painting is $270. Holmstrom Gallery earns a 20% commission on each painting sold.
The steps are:
Calculate the commission by multiplying the retail price by the commission rate:270 × 0.20 = 54
Determine the net revenue for one painting: Subtract the commission from the retail price:270 − 54 = 216
Calculate total revenue for the paintings sold:Only one painting was sold by December 31, 2024. So, the total revenue Kerianne should recognize for 2024 is the net revenue from one painting:
216 × 1 = 216

if the mechanical advantages of the component machines in the peeler are 2, 3, and 12, what is the overall mechanical advantage of the apple peeler?
Final answer:
The overall mechanical advantage of an apple peeler with component mechanical advantages of 2, 3, and 12 is the product of these numbers, which is 72. This implies that the input force applied to the apple peeler is multiplied by 72 times.
Explanation:
The student is asking about the overall mechanical advantage of an apple peeler, which is a complex machine made up of components with individual mechanical advantages. To find the total mechanical advantage of a complex machine, you would multiply the mechanical advantages of each component together.
Given that the mechanical advantages of the component machines are 2, 3, and 12, we can calculate the overall mechanical advantage as follows:
Mechanical Advantage of Component 1: 2
Mechanical Advantage of Component 2: 3
Mechanical Advantage of Component 3: 12
To find the overall mechanical advantage, just multiply these together:
Overall Mechanical Advantage = 2 × 3 × 12 = 72
So, the overall mechanical advantage of the apple peeler is 72. This means the input force is multiplied 72 times.
