Desmond's monthly Netflix subscription costs $14.
If he charges it to his credit card each month for 7
months without making any payments, what will
his debt be?
Explain how you would solve this problem.
What is the answer?
Answers
Answer:
Desmond has a debt of $98.
Step-by-step explanation:
We are given that Desmond has a monthly Netflix subscription that charges him $14. Since it is a monthly subscription, it is a recurring charge.
We are also given that he does not make payments for 7 months. This means that the subscription is recurring for seven months.
Therefore, if he is charged $14 monthly and is charged that for 7 months, we can say that he is charged $14 seven times.
Therefore, we can create an equation that solved how much his debt would be based on this information.
\(\displaystyle14(7) = c\\\\14\times7=98\\\\c = 98\)
Therefore, Desmond has a debt of $98.

A truck was purchased for $188000 and it was estimated to have a $32000 salvage value at the end of its useful life. Monthly depreciation expense of $2600 was recorded using the straight-line method. The annual depreciation rate is a.16,60% b.6.67% c.20.00% d.1.67%.
Answers
Answer: 20%
Step-by-step explanation: Annual depreciation = $2,600 * 12 = $31,200
Annual depreciation rate = Annual depreciation /Depreciable costs
= $31,200 / ($188,000 - $32,000)

Step-by-step explanation:
You can make a ratio - 325:5, then we can simplify it to 65:1, where we are comparing # of beats in 1 minute. Now, we can just multiply both sides by two, getting us 130:2, which is just 130 beats.
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55 . He buys a total of 11 pieces of fruit.
Answers
A system of linear equations to describe this situation is given by:
A + O = 11.
0.80A + 0.95O = 9.95.
Harry bought six (6) apples and five (5) oranges from this store.
How to write a system of linear equations?In order to write a system of linear equations to describe this situation, we would assign variables to the amount of apples and oranges respectively, and then translate the word problem into algebraic equation as follows:
Let the variable A represent the amount of orange Harry bought.Let the variable O represent the amount of apple Harry bought.Since Harry bought a total of 11 pieces of fruit, we have:
A + O = 11 .....equation 1.
Since the cost of apples is $0.80 each and oranges cost $0.95 each, we have:
0.80A + 0.95O = 9.95 .....equation 2.
Part B.From equation 1, we have:
O = 11 - A .....equation 3.
Substituting equation 3 into equation 2, we have:
0.80A + 0.95O = 9.95
0.80A + 0.95(11 - O) = 9.95
Apples, A = 0.90/0.15
Apples, A = 6.
For the number of oranges, we have:
Oranges, O = 11 - A
Oranges, O = 11 - 6

The measure of distance x, that is, the distance between a point P and the point of horizon, is equal to 284.372 miles.
How to find the distance to the earth horizon from a given point
In this problem we must determine the distance between a point P located about earth's circumference and the point of horizon, located on earth's circumference. Since the line between these two points is tangent to earth, then, distance x can be found by Pythagorean theorem:
x = √[(3959 mi + 10.2 mi)² - (3959 mi)²]
x = 284.372 mi

Avoiding an accident when driving can depend on reaction time. That time, measured in seconds from the moment the driver see danger until they step on the brake pedal, can be described by the Normal model with a mean of 1.5 seconds and a standard deviation of 0.18 seconds.
Note that this scenario is talking about a population distribution. There is no discussion of a sample or sample size. Therefore, you do not need to adjust the standard deviation that is given before using the normalcdf and invNorm commands.
a) What percent of drivers have a reaction time greater than 1.8 seconds?
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 2 decimal places:
b) Describe the reaction time of the slowest 10% of all drivers? (Hint: The slower a person reacts, the higher their reaction time so this is looking at the right tail of the distribution)
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 2 decimal places:
Answers
Using the normal distribution, it is found that:
a) 4.75% of drivers have a reaction time greater than 1.8 seconds.
b) The reaction time is of at least 1.73 seconds.
Normal Probability DistributionIn a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively:
\(\mu = 1.5, \sigma = 0.18\)
Item a:
The proportion is one subtracted by the p-value of Z when X = 1.8, hence:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{1.8 - 1.5}{0.18}\)
\(Z = 1.67\)
\(Z = 1.67\) has a p-value of 0.9525.
1 - 0.9525 = 0.0475 = 4.75%.
4.75% of drivers have a reaction time greater than 1.8 seconds.
Item b:
The reaction time is of at least X seconds, in which X is the 90th percentile, that is, X when Z = 1.28, hence:
\(Z = \frac{X - \mu}{\sigma}\)
\(1.28 = \frac{X - 1.5}{0.18}\)
\(X - 1.5 = 1.28(0.18)\)
\(X = 1.73\)
The reaction time is of at least 1.73 seconds.

Let N be the number of data entries in a population and n be the number of data entries in a sample data set. Describe the difference between the calculation of population standard deviation and sample standard deviation.
Answers
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.

Come up with a monomial expression and solve it.
What is a monomial expression?A monomial expression is an algebraic expression that consists of a single term. It is an expression that can contain variables, constants, and non-negative integer exponents, but there should be no addition or subtraction between different terms.
Here are a few examples of an monomial expression:
5x-2xy²3a⁵7m³n²\(\hrulefill\)
Let's work with the monomial expression, 3x²y³z.
To solve this expression, I assume you would like to evaluate it for specific values of the variables x, y, and z. So let x=3, y=2, and z=1.
Plug these values into the expression:
3x²y³z
=> 3(3)²(2)³(1)
=> 3(9)(8)(1)
=> 27(8)(1)
=> 216(1)
=> 216
Thus, the expression is solved.

A sketch of the graph is recommended but it is not enough for your explanation
Answers
Using asymptote concepts, it is found that the function is:
\(f(x) = \frac{10x^2}{x^2 + 2x - 3}\)
First we find the vertical asymptotes, which are the values for which the function is outside the domain.We consider a fraction, thus, deciding to place vertical asymptotes at \(x = -1\) and at \(x = 3\), the denominator is:\((x + 1)(x - 3) = x^2 + 2x - 3\)
The horizontal asymptote is the limit of f(x) as x goes to infinity. We suppose it is 10, thus the numerator is \(10x^2\), as it has to be the same degree of the denominator.Which means that the function is:
\(f(x) = \frac{10x^2}{x^2 + 2x - 3}\)
The graph is sketched below.
