what is 2.161616 as a fraction and as a mixed number
Answer:
see explanation
Step-by-step explanation:
We require to create 2 equations with the repeating value placed after the decimal point.
let x = 2.1616...... → (1) Multiply both sides by 100
100x = 216.1616..... → (2)
Subtract (1) from (2) to eliminate the repeating decimal.
99x = 214 ( divide both sides by 99 )
x = [tex]\frac{214}{99}[/tex] = 2 [tex]\frac{16}{99}[/tex] as a mixed number
Thus
2.1616...... = [tex]\frac{214}{99}[/tex] = 2 [tex]\frac{16}{99}[/tex]

John Slow is driving from Boston to the New York area, a distance of 180 miles at a constant speed, whose value is uniformly distributed between 30 and 60 miles per hour. What is the PDF of the duration of the trip?
To find the PDF (Probability Density Function) of the duration of the trip, we need to determine the distribution of the speed and calculate the corresponding duration.
Given that the speed of John Slow is uniformly distributed between 30 and 60 miles per hour, we have a continuous uniform distribution over this interval.
The duration of the trip can be calculated by dividing the distance (180 miles) by the speed (v) since speed = distance/time, rearranging the equation gives time = distance/speed.
Let's denote the duration of the trip as T. We can express T in terms of the speed (v) as follows:
T = 180 miles / v
To find the PDF of T, we need to determine the probability density function of v. Since v is uniformly distributed between 30 and 60 mph, its PDF is a constant over this interval.
The width of the interval is (60 - 30) = 30 mph, and since it is a uniform distribution, the height of the PDF is 1/30 mph^(-1) to ensure the total area under the PDF equals 1.
Therefore, the PDF of T is given by:
PDF(T) = PDF(v) * |dt/dv|
Since v = 180/T, we can differentiate this equation with respect to T to find |dt/dv|:
|dt/dv| = |-180/T²|
Substituting the PDF of v and |dt/dv| into the PDF of T:
PDF(T) = (1/30 mph^(-1)) * |-180/T²|
Simplifying further, we have:
PDF(T) = 6/T² mph^(-1)
Therefore, the PDF of the duration of the trip is 6/T² mph^(-1).

which of the following units could apply to this variable?
OA. workers
B. buildings
The units that could apply to the variable t representing the amount of time the workers have left to clean the windows are hours or minutes, not workers or buildings. None of the given Options.
The variable t represents the amount of time the workers have left to clean the windows. From the given information, it is stated that it takes a total of 12 hours to clean the windows of the office building, and on the first day, the workers were able to clean for 9 hours.
Therefore, the remaining time left to clean the windows can be expressed as 12 - 9 = 3 hours.
Based on this, we can determine the appropriate units for the variable t. Since t represents time, the units that apply to this variable should also be units of time. In this case, the units of time that could apply to the variable t are hours or minutes.
OA. workers is not an appropriate unit for the variable t because it represents the number of individuals performing the task, not the amount of time remaining.
B. buildings is also not an appropriate unit for the variable t because it represents the number of office buildings, which is unrelated to the amount of time left to clean the windows. None of the given Options is correct.

The shoe store manager borrowed $17,000.00 from the bank to purchase 1000 pairs of shoes. The bank charges a simple interest rate of 5% per year on a loan to a business. If it takes 3 years to pay back the loan and interest, what is the total amount of interest that the shoe store will pay? (2 points)
The total amount that the shoe store will pay back to the bank is $2550. I know this because I used I=PRT which would then be 1700*0.05*3 which would then lead the interest to be $2550.
b) What is the total amount, including interest, that the shoe store must pay on the loan? (2 points)
The total amount will be $19,250. I know this because I did 17,000+2550 to get 19,250.
c) How could you use estimation to determine if your answer is reasonable? Explain. (2 points)
JUST ANSWER C! Thank you
Answer:
Step-by-step explanation:
A) Using the formula for calculating simple interest. This is expressed as:
SI = PRT/100
P is the principal = 17,000
Rate = 5%
Time = 3years
SI = 17,000×5×3/100
SI = 170×5×3
SI = 170×15
SI = $2550
Hence the total amount that the shoe store will pay back to the bank is $2550.
B) To get the total amount plus loan to be paid, we will use the formula below;
Amount = Principal + Interest
Amount = $17000+$2550
Amount = $19550
Hence the total amount will be $19500
C Based on the calculation, the estimate was gotten by simply multiplying 15 by 17 to get $225 then multiply by 10 to get $2250 making it thousands of dollars.
The total loan amount was derived by simply adding the original amount borrowed with the interest charges by the bank

A clinic has several doctors. Every patient, on average, requires about 27 minutes with a doctor Each doctor works 8 hours per day and 7 days per week. The clinic also operates 8 hours per day and 7 days per week. Based on past observations, the clinic must serve 122 patients per day. How many doctors should the clinic hires in order to serve 122 patients per day? Use at least 4 decimals in your calculation and answer.
The clinic should hire at least 7 doctors in order to serve 122 patients per day.
To determine how many doctors the clinic should hire in order to serve 122 patients per day, we need to calculate the number of patients each doctor can see within their working hours.
Let's start by calculating the total number of minutes each doctor works per day. Since each doctor works 8 hours per day and there are 60 minutes in an hour, the total minutes worked by a doctor per day would be 8 hours × 60 minutes = 480 minutes.
Next, we need to find out how many patients a doctor can see within their working hours. Given that each patient requires an average of 27 minutes with a doctor, the number of patients a doctor can see per day would be 480 minutes ÷ 27 minutes per patient = 17.7778 patients.
Since we can't have a fractional number of patients, we need to round this number up to the nearest whole number to ensure that each patient gets the required attention. Therefore, each doctor can see approximately 18 patients per day.
To serve 122 patients per day, we divide the total number of patients by the number of patients each doctor can see per day: 122 patients ÷ 18 patients per doctor = 6.7778 doctors.
Again, we can't have a fractional number of doctors, so we need to round this number up to the nearest whole number. Therefore, the clinic should hire at least 7 doctors to serve 122 patients per day.
In summary, the clinic should hire at least 7 doctors in order to serve 122 patients per day.

if treasury bills are currently paying 6.4 percent and the inflation rate is 1.5 percent, what is the approximate and the exact real rate of interest? (do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)
The approximate real rate of interest is 4.86% and the exact real rate of interest is 4.98% is the correct naswer.
Real Rate of Interest: Real rate of interest is the actual interest earned or paid on an investment or loan, irrespective of the impact of inflation. It can be calculated by subtracting the rate of inflation from the nominal rate of interest. Therefore, the nominal rate of interest adjusted for inflation gives us the real rate of interest.
Approximate Real Rate of Interest: By using the formula Real rate = (1 + nominal rate) / (1 + inflation rate) - 1Real rate = (1 + 6.4%) / (1 + 1.5%) - 1
Real rate = 0.0486 or 4.86%
Thus, the approximate real rate of interest is 4.86%.
Exact Real Rate of Interest: The exact real rate of interest can be calculated using the Fisher effect formula that is: Real Rate = [(1+ nominal rate) / (1 + inflation rate)] - 1Real Rate = [(1 + 6.4%) / (1 + 1.5%)] - 1
Real Rate = 0.0498 or 4.98%
Thus, the exact real rate of interest is 4.98%.
In conclusion, the approximate real rate of interest is 4.86% and the exact real rate of interest is 4.98%.

Write the equation of the line in slope intercept form
Point: (-2,8) slope: 3
show work
Answer:
y=3x+14
Step-by-step explanation:
To start, you know what m is; it's just the slope, which you said was 3. So you can right away fill in the equation for a line somewhat to read:
y=3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-2,8). When x of the line is -2, y of the line must be 8.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-2,8).
So, why not plug in for x the number -2 and for y the number 8? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-2,8). y=mx+b or 8=3 × -2+b, or solving for b: b=8-(3)(-2). b=14.
The equation of the line that passes through the point (-2,8) with a slope of 3
is
y=3x+14

One of the pair of complementary
angle is 30°. find the next angle and
find the ratio of these pair of complemtary
angles as well
Answer:
The other angle is 60°
Their ratio is 1 : 2
Step-by-step explanation:
Let us revise some special angles
A pair of complementary angles is two angles their sum is 90°
A pair of supplementary angles is two angles their sum is 180°
In the question
∵ One angle of the pair of complementary angle = 30°
∵ The sum of the two complementary angles = 90°
→ Subtract 30° from 90° to find the other angle
∴ The other angle = 90° - 30° = 60°
∴ The other angle is 60°
To find the ratio of them put them in the form of the ratio, then simplify the ratio to its simplest form
∵ Their ratio = 30 : 60
→ Divide both sides by 10
∴ Their ratio = 3 : 6
→ Divide both sides by 3
∴ Their ratio = 1 : 2
∴ Their ratio is 1 : 2

Irrational numbers C. a. Integers b. Irrational numbers D. a. Integers b. Rational numbers
Answer:
The correct option is;
B. a. Whole number b. Irrational number
Step-by-step explanation:
The height, h of the equilateral triangle = 3·√2·s
The item by which equilateral triangle is made = 2-inch toothpicks
Therefore, we have;
The sides of the equilateral triangle = Comprises multiples of 2 inches
Therefore, the sides of the equilateral triangle is a whole number
The height of the triangle is the product of the side and (√3)/2
Therefore, the height of the triangle is an irrational number
The correct option is A. a. Whole number b. Irrational number.
A whole number are the positive counting numbers, 0, 1, 2, ..., while an integer includes negative numbers which is not possible for a real triangle.

C2 Let L: R"→ R" be a linear mapping. (a) Prove that L(0) = 0. (b) Explain what (a) says about a mapping M: R"→ R such that M(0) + 0.
In part (a), we need to prove that for a linear mapping L:[tex]R^n[/tex] → [tex]R^n[/tex], L(0) = 0. In part (b), we are asked to explain what this implies about a mapping M: [tex]R^n[/tex] → R.
In part (a), we need to show that for any linear mapping L: [tex]R^n[/tex] →[tex]R^n[/tex], the image of the zero vector, L(0), is also the zero vector, 0.
To prove this, we consider the linearity property of L. By definition, a linear mapping preserves scalar multiplication and vector addition. Since the zero vector, 0, is the additive identity in R^n, we can write 0 = 0 * 0, where 0 is the scalar and 0 is the zero vector.
Applying the linearity property, we have L(0) = L(0 * 0) = 0 * L(0) = 0. Thus, L(0) is indeed the zero vector, as required.
In part (b), if we consider a mapping M: [tex]R^n[/tex] → R, we can still apply the same reasoning. Since M is a mapping from R^n to R, the zero vector in R^n is mapped to the zero scalar in R. In other words, M(0) = 0.
This result implies that for any mapping M: [tex]R^n[/tex] → R, the zero vector in the domain (R^n) is always mapped to the zero scalar in the codomain (R).
In summary, for a linear mapping L:[tex]R^n[/tex] → [tex]R^n[/tex], L(0) is always the zero vector. This property holds true for any linear mapping. In the case of a mapping M: [tex]R^n[/tex] → R, the zero vector in the domain is always mapped to the zero scalars in the codomain.

QUESTION 3 Scenario: Pizza Supply and Demand. Qº The demand for pizza is represented by PD = 10- and the supply of pizza is represented by PS = 4 dollars. The market for pizza is perfectly competitiv
The equilibrium price of pizza in this scenario is 2.5 dollars. At this price, the quantity demanded and supplied of pizza are both equal to 7.5
In the context of this scenario, PD represents the demand for pizza, and it is determined by a few factors, including price.
The formula PD = 10- indicates an inverse relationship between the price of pizza and the quantity demanded.
This means that as the price of pizza increases, the quantity demanded will decrease.
On the other hand, as the price of pizza decreases, the quantity demanded will increase.
PS represents the supply of pizza, and it is also determined by a few factors, including price.
The formula PS = 4 indicates that the quantity supplied of pizza is fixed at 4.
This means that the quantity of pizza supplied will not change regardless of the price of pizza.
The market for pizza is perfectly competitive, meaning that there are a large number of buyers and sellers, all of whom have equal access to the market information.
In such a market, the price of pizza is determined by the interaction of the demand and supply forces.
At the equilibrium price, the quantity demanded and supplied are equal.
In other words, the quantity demanded of pizza at the given price equals the quantity supplied.
The equilibrium price can be found by setting the demand and supply equations equal to each other and solving for price: PD = PS10- = 4P 10- = 4P P = 2.5
Thus, the equilibrium price of pizza in this scenario is 2.5 dollars.
At this price, the quantity demanded and supplied of pizza are both equal to 7.5
