Jim buys a skateboard for $200. The value of the skateboard depreciates by 15% each year
since buying it. Create a function to represent the value of the skateboard, f(2), in dollars,
after 3 years since buying it.
Answers
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.
A cell phone beeps every 4 minutes. Another cell phone beeps every 5 minutes. What are the first three times that the cell phones beep at the same time?
Answers
Answer:
20, 40, 60
Step-by-step explanation:
We can find the LCM by making a list which is my favorite way.
Cell phone number 1: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Cell phone number 2: 5, 10, 15, 20, 25, 30, 35 40, 45, 50, 55, 60
Answer:
The first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.
Step-by-step explanation:
Let the first cell phone be A, that is, A beeps every 4 minutes
and let the other cell phone be B, that is, B beeps every 5 minutes.
Cell phone A will be at the 4th, 8th, 12th, 16th and 20th minutes while cell phone B will beep at the 5th, 10th, 15th and 20th minutes. Hence, the first time the cell phones will beep together is the 20th minute.
Cell phone A will then beep at the 24th, 28th, 32nd, 36th and 40th minutes while cell phone B will beep at the 25th, 30th, 35th and 40th minutes. The second time the cell phones will beep together is the 40th minute.
Cell phone A will beep at the 44th, 48th, 52nd, 56th and 60th minutes while cell phone B will beep at the 45th, 50th, 55th and 60th minutes. The third time the cell phones will beep together is the 60th minute.
Hence, the first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.

Let's call the length of the rectangle "L" and the width "W". The rectangle has two sides of length L and two sides of length W, so the perimeter of the rectangle is: 2L + 2W The semicircle has a diameter equal to the width of the rectangle (W), so the circumference of the semicircle is: 1/2 (pi) W To get the total perimeter, we need to add the circumference of the semicircle to the perimeter of the rectangle. Since the semicircle only covers half of the width of the rectangle, we only need to add one width (W) to the perimeter of the rectangle. So the total perimeter is: 2L + 3W + 1/2 (pi) Wevaluate C(4,2)C(4,2) represents the number of ways to choose 2 items from a set of 4 distinct items. The formula for C(n,r) is n! / (r! * (n-r)!), where n is the total number of items and r is the number of items being chosen. Plugging in the values for C(4,2), we get: C(4,2) = 4! / (2! * (4-2)!) = 24 / (2 * 2) = 6 Therefore, there are 6 ways to choose 2 items from a set of 4 distinct items.Let f(x)=\sqrt(x) and g(x)=5\sqrt(x). Find (f-g)(x).(f-g)(x) represents the difference between f(x) and g(x). So we can write: (f-g)(x) = f(x) - g(x) Substituting the given expressions for f(x) and g(x), we get: (f-g)(x) = sqrt(x) - 5sqrt(x) To simplify this expression, we can factor out sqrt(x) as a common factor: (f-g)(x) = sqrt(x) * (1 - 5) Simplifying the expression in the parentheses, we get: (f-g)(x) = -4sqrt(x) Therefore, (f-g)(x) = -4sqrt(x)
With dependent events involving colored tiles,after every pick, does the likelihood of picking a particular color of tile go up or down? Explain
Answers
Answer:
Down
Explanation:
Dependent events are events in which the outcomes are affected by previous outcomes.
In order to answer this question, the illustration below is used.
Consider a bag with 5 red and 5 blue tiles.
Since the events are dependent, the selection is made without replacement.
\(\begin{gathered} P(\text{selecting 1st red tile)}=\frac{5}{10}=0.5 \\ P(\text{selecting 2nd red tile)}=\frac{4}{9}=0.44 \\ P(\text{selecting 3rd red tile)}=\frac{3}{8}=0.375 \end{gathered}\)Observe that after each pick of the red color, the likelihood of picking a red tile decreases.
Therefore, after every pick, the likelihood of picking a particular color of tile go down.

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 2/7
There are 16 red marbles in the bag and each is equally likely to be chosen.
Work out how many marbles in total there must be.
Answers
Answer: 56
Step-by-step explanation:
Given that :
Marbles in bag are only red and blue ;
Probability of randomly choosing a red = 2/7
Number of red marbles in bag = 16
The total Number of marbles =?
P(choosing a red marble) = required outcome / Total possible outcomes
Required outcome = number of red marbles
Total possible outcomes = total number of blue and red marbles
Total number of blue and red marbles = x
P(choosing a red marble) = required outcome / Total possible outcomes
2/7 = 16 / x
Cross multiply
2x = 16 * 7
2x = 112
x = 112 / 2
x = 56 marbles
Total number of marbles = 56

Answers
To estimate the conditional probabilities for Pr(A = 1|+), Pr(B = 1|+), and Pr(C = 1|+), we need to calculate the probabilities of each event occurring given that the class is positive (+).
Let's analyze the given data and calculate the conditional probabilities:
Out of the 8 instances provided, there are 4 instances where the class is positive (+). Let's denote these instances as +1, +2, +5, and +6.
For Pr(A = 1|+), we calculate the proportion of instances among the positive class where A = 1. Out of the four positive instances, +2 and +5 have A = 1. Therefore, Pr(A = 1|+) = 2/4 = 0.5.
For Pr(B = 1|+), we calculate the proportion of instances among the positive class where B = 1. Out of the four positive instances, +5 has B = 1. Therefore, Pr(B = 1|+) = 1/4 = 0.25.
For Pr(C = 1|+), we calculate the proportion of instances among the positive class where C = 1. Out of the four positive instances, +5 and +6 have C = 1. Therefore, Pr(C = 1|+) = 2/4 = 0.5.
To summarize:
- Pr(A = 1|+) = 0.5
- Pr(B = 1|+) = 0.25
- Pr(C = 1|+) = 0.5
It's important to note that these probabilities are estimated based on the given data. Depending on the context and the underlying distribution of the data, these probabilities might not be accurate representations in other scenarios.

A bakery sells 10 types of pies: apple, cherry, blueberry, strawberry, peach, key lime, pumpkin, sweet potato, pecan, and chocolate. Assume that it has an unlimited supply of each type. How many different ways are there to choose 6 pies from these 10 types if... a. ...there are no restrictions? b. ...all the pies chosen are of the same type? C. ...all the pies chosen are of different types? d. ...at least 2 apple pies and 1 cherry pie are chosen? e....at most 3 key lime pies are chosen?
Answers
The required set of combinations are:
a. 210, b. 10, c. 210, d. 10, e. 481
a. To choose 6 pies from 10 types without any restrictions, we can use the combination formula:
10C6 = 210 ways.
b. To choose 6 pies of the same type, we can simply choose one of the 10 types, so there are 10 ways.
c. To choose 6 pies of different types, we can use the permutation formula:
10P6 = 151,200 ways.
d. To choose at least 2 apple pies and 1 cherry pie, we can split this into two cases:
Case 1: 2 apple pies, 1 cherry pie, and 3 other pies. We can choose the 2 apple pies from the 2 apple pies available, the 1 cherry pie from the 1 cherry pie available, and the 3 other pies from the remaining 8 types. Using the multiplication principle, there are (2C2) x (1C1) x (8C3) = 56 ways to choose the pies in this case.
Case 2: 3 or more apple pies, 1 cherry pie, and 2 other pies. We can choose the 3 or more apple pies from the 2 apple pies available, the 1 cherry pie from the 1 cherry pie available, and the 2 other pies from the remaining 8 types. Using the multiplication principle, there are (2C3 + 2C4 + 2C5 + 2C6) x (1C1) x (8C2) = 700 ways to choose the pies in this case.
Adding the number of ways from both cases, we get a total of 56 + 700 = 756 ways.
e. To choose at most 3 key lime pies, we can split this into three cases:
Case 1: 0 key lime pies. We can choose any 6 pies from the remaining 9 types, so there are 9C6 = 84 ways to choose the pies in this case.
Case 2: 1 key lime pie. We can choose 1 key lime pie from the 3 available, and the remaining 5 pies from the remaining 9 types. Using the multiplication principle, there are (3C1) x (9C5) = 945 ways to choose the pies in this case.
Case 3: 2 or 3 key lime pies. We can choose 2 or 3 key lime pies from the 3 available, and the remaining pies from the remaining 9 types. Using the multiplication principle, there are (3C2 + 3C3) x (9C4 + 9C3) = 10,395 ways to choose the pies in this case.
Adding the number of ways from all three cases, we get a total of 84 + 945 + 10,395 = 11,424 ways.

A rhombus has an area of 20 cm^2. One diagonal is 10 cm. What is the other diagonal
Answers
The other diagonal of the rhombus is 4 cm.
The other diagonal of the rhombus can be found using the formula for the area of a rhombus, which is A = (d₁ × d₂)/2, where d₁ and d₂ are the lengths of the diagonals.
We're given that the area of the rhombus is 20 cm² and that one diagonal (d1) is 10 cm. Plugging these values into the formula, we get:
20 = (10 × d₂)/2
Simplifying, we get:

C) is, or appears makes no difference is red.
Answers
Strictly speaking, to say that an apple is red means that B) it appears red.
What does it mean to say that an apple is red?When we say that an apple is red, strictly speaking, it means that it appears red.
The color we perceive is not an inherent property of the apple itself, but rather the result of how light interacts with the apple's surface and how our eyes perceive that interaction.
The color we see is a subjective experience influenced by various factors, such as lighting conditions, our perception of color, and any color deficiencies we may have.
While an apple may reflect and absorb certain wavelengths of light that we interpret as "red," it's important to recognize that color perception is subjective and can vary from person to person.
The statement "an apple is red" acknowledges that our perception of color is based on the appearance of the apple rather than making an absolute statement about its inherent color.

There are two common methods for measuring the concentration of a pollutant in fish tissue. You apply both methods to a random sample of 18 carp. The primary interest is to know whether the two methods differ. Then this is a typical a. paired t-test b. one-sample Z-test c. two-sample Z-test d. two-sample t-test
Answers
The appropriate test for comparing the means of two measurement methods is a paired t-test. Therefore, the answer is (a) paired t-test.
A paired t-test is used to compare the means of two related groups or samples. In this case, the two measurement methods are applied to the same sample of carp, and the results of the two methods are paired or matched by carp. The paired t-test calculates the mean and standard deviation of the differences between the two methods for each carp, and then tests whether the mean difference is significantly different from zero.
The paired t-test is an appropriate test in this scenario because it accounts for the variability within the sample and reduces the potential impact of confounding factors, such as differences in the size or age of the fish. Additionally, since the sample size is relatively small (18 carp), a t-test is more appropriate than a z-test, which assumes larger sample sizes and a known population standard deviation.

The equation f(x) = -12(x-0.5)²+3 represents the height of an eraser cap launched from a mousetrap catapult on the floor over time in seconds (x).
The graph of this equation will be a downward-facing parabola, with the vertex at (0.5, 3) and an axis of symmetry at x = 0.5.
The maximum height reached by the eraser cap is 3 feet, which occurs at x = 0.5.
