A man invests $16800 in a savings plan that pays simple interest at a rate of 5% per annum. Find the time taken for his investment to grow to $19800.
Answer: 3.57 years
Step-by-step explanation:
Based on the question given, the interest is the difference between the amount and the principal which will be:
= $19800 - $16800
= $3000
The formula for Simple interest is given as:
Interest = Principal × Rate × Time
3000 = 16800 × 5% × Time
3000 = 16800 × 0.05 × Time
3000 = 840 × Time
Time = 3000 / 840
Time = 3.57
The time taken to grow the investment is 3.57 years

If f(x)=16x-30 and g(x)=14x-6, for which value of x does (f-g)(x)=0?
12
13
14
The value of x for which (f - g)(x) = 0 is x = 12.
To find the value of x for which (f - g)(x) = 0, we need to subtract g(x) from f(x) and set the resulting expression equal to zero. Let's perform the subtraction:
(f - g)(x) = f(x) - g(x)
= (16x - 30) - (14x - 6)
= 16x - 30 - 14x + 6
= 2x - 24
Now, we can set the expression equal to zero and solve for x:
2x - 24 = 0
Adding 24 to both sides:
2x = 24
Dividing both sides by 2:
x = 12
Therefore, the value of x for which (f - g)(x) = 0 is x = 12.

Which table shows a linear function
The table that shows a linear function include the following: B. table B.
What is a linear function?In Mathematics, a linear function is a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, a linear function has the same (constant) slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.
In this context, we have:
Slope = (0 - 2)/(-3 + 5) = (2 - 0)/(-3 + 1) = -1

if a given graph that shows one of the x-intercepts is (-3 0) and the vertext is (0,-9) what is the quadratic equation in standard form?
The quadratic equation can be written as y = x² - 9.
To find the quadratic equation in standard form, we need to use the vertex form of the quadratic equation, which is given by:
y = a(x - h)² + k
where (h, k) is the vertex and a is a constant that determines the shape of the parabola.
We know that the vertex is (0, -9), so we can substitute these values into the equation:
y = a(x - 0)² - 9
Simplifying this equation, we get:
y = ax² - 9
Now, we need to find the value of a. We know that one of the x-intercepts is (-3, 0), which means that the parabola intersects the x-axis at x = -3. This tells us that (-3, 0) is a solution of the equation, so we can substitute these values into the equation and solve for a:
0 = a(-3)² - 9
0 = 9a - 9
9 = 9a
a = 1
Therefore, the quadratic equation in standard form is:
y = x² - 9

what is the expected number of sixes appearing on three die rolls
To find the expected number of sixes appearing on three die rolls, we can calculate the probability of rolling a six on each individual roll and then multiply it by the number of rolls.
The probability of rolling a six on a single roll of a fair die is 1/6, since there are six equally likely outcomes (numbers 1 to 6) and only one of them is a six.
Since the rolls are independent events, we can multiply the probabilities together to find the probability of rolling a six on all three rolls:
(1/6) * (1/6) * (1/6) = 1/216
Therefore, the probability of rolling a six on all three rolls is 1/216.
To find the expected number of sixes, we multiply the probability by the number of rolls:
Expected number of sixes = (1/216) * 3 = 1/72
So, the expected number of sixes appearing on three die rolls is 1/72.

Name all angles when there are two parallel lines cut by a transversal?
Alternate interior angles
Corresponding angles
Vertically opposite
From figure 1,
Since the angles marked with colour fulfil the vertically opposite angles properties ,so
(2x+35)° = (8x-49)°
⇒(2x-8x)=(-49-35)°
⇒-6x=-84
⇒x = 14°
Hence , x = 14°
From figure 2,
Since the angles marked are corresponding angles,therefore on equating both angles we get
(10x-18)°=(15x-48)°
⇒(10x-15x)=(-48+18)°
⇒-5x = -30°
⇒ x = 6°
From figure 3,
Since the given two angles are alternate interior angles ,so
(7x+5)°=(12x-75)°
⇒(7x-12x)=(-75-5)°
⇒-5x=-80°
⇒x = 16°
From figure 4 ,
Since the two angles lies in a straight line ,so sum is 180°
(27x-21)°+(10x-16)°=180°
⇒37x -37° = 0
⇒ x = 1°

Match the technique on the left with its datapreprocessing function on the right. Binning Imputation Dimension reduction Recoding Omission Mathematical manipulation
Binning - Recoding
Imputation - Mathematical manipulation
Dimension reduction - Mathematical manipulation
Recoding - Mathematical manipulation
Omission - N/A (This is not a data preprocessing technique, but rather a decision to exclude certain data points from analysis)
Mathematical manipulation - N/A (This is not a specific data preprocessing technique, but rather a broad category that includes various techniques such as scaling, normalization, transformation, etc.)
Binning: This technique is used to transform numerical data into categorical data by dividing a continuous variable into discrete intervals or "bins". This can be useful for reducing the impact of small variations in numerical data, and for making data more manageable for certain types of analysis. The preprocessing function for binning is usually recoding, although it could also involve mathematical manipulation to create the bins.
Imputation: This technique is used to replace missing data values with estimated values based on other available data. This can be useful for maintaining the size and integrity of a dataset, and for avoiding bias in statistical analysis. The preprocessing function for imputation is mathematical manipulation, which may involve calculating average or median values, or using more sophisticated methods such as regression or machine learning.
Dimension reduction: This technique is used to reduce the number of variables or features in a dataset, while preserving as much of the relevant information as possible. This can be useful for simplifying complex datasets, speeding up analysis, and avoiding overfitting in machine learning models. The preprocessing function for dimension reduction is mathematical manipulation, which may involve techniques such as principal component analysis (PCA), factor analysis, or feature selection.
Recoding: This technique is used to transform categorical data into numerical data, or to transform data from one type or format to another. This can be useful for making data more compatible with certain types of analysis or modeling, and for improving the interpretability of results. The preprocessing function for recoding is usually mathematical manipulation, although it could also involve binning or other techniques.
Omission: This technique involves excluding certain data points or observations from a dataset, either because they are irrelevant or because they are problematic in some way (e.g. outliers or errors). This can be useful for improving the quality and reliability of data, and for increasing the efficiency of analysis. However, it can also lead to bias or incomplete results if the omitted data is important. The preprocessing function for omission is N/A, since it involves simply removing data rather than transforming it.
Mathematical manipulation: This is a broad category of data preprocessing techniques that involves various types of mathematical and statistical operations on data, such as scaling, normalization, transformation, or feature engineering. These techniques are used to prepare data for analysis or modeling, to improve the quality and relevance of results, and to reduce the impact of noise or errors. The preprocessing function for mathematical manipulation is usually mathematical manipulation itself, although it could also involve other techniques such as binning, imputation, or dimension reduction in some cases

Amy earned $25 after babysitting for 3 hours. If she always charges the same rate, how much will she make after working for 7 hours?
Answer:
$58.33
Step-by-step explanation:
Set up a proportion where x is the amount she makes for 7 hours:
\(\frac{3}{25}\) = \(\frac{7}{x}\)
Cross multiply and solve for x:
3x = 175
x = 58.33
So, after working for 7 hours, she will make $58.33
Answer:
About 60-65$
Step-by-step explanation:
Because every 3 hours she gets $25 and she worked 7 hours so there's 6 in 7 hours so 25+25 is 50 and the other hour would be half of 25 so 12.5 so between 60-65. Im so sorry if its wrong hope it worked tho! <3
The midpoint of AB is M(-3, -3). If the coordinates of A are (-5, -1), what are
the coordinates of B?
The midpoint of AB is M(-3, -3), and the coordinates of A are (-5, -1) then (-1,-5) are the coordinates of B.
What is Coordinate ?
The abscissa, also known as the x coordinate of the point, is the separation of a point from the y-axis scaled with the x-axis. The term "ordinate" refers to a point's separation from the x-axis when scaled with the y-axis. Coords are the collective noun for the abscissa and ordinate.
What is midpoint?
A point that is halfway between two other points is considered to be a line segment's midpoint. The distance between the midpoint and each endpoint is the same.
Given that;
midpoint of AB is M(-3, -3),
coordinates of A are (-5, -1),
then,

Luis deposited $300 into his bank account. He now has $4,511. Enter and solve an equation to find how much was in his account before the deposit. Let a represent the variable.
You run Colgate and sell toothpaste. You are trying to forecast demand for 2022 , and you have sales data for the past 5 years, in \$M:
2017: 55
2018: 45
2019: 100
2020: 50
2021: 100
First, generate 4 forecasts using the following methods: naive, simple mean method, 3 period moving average, 2 period weighed moving average (with weights of 0.8 and 0.2 for the the most recent and second most recent period, respectively. Anthony is in marketing, and he's very worried about being understocked, so he picks his favorite 2022 forecast based on this worry. Bria, on the other-hand is really worried about big forecasting errors in either direction, and she picks her favorite 2022 forecast using her preferred metric. What is the absolute difference in Anthony's favorite forecast and Bria's favorite forecast? Round to the nearest $M. For example, if your answer is $4.39M, enter 4 in the box.
The absolute difference between Anthony's favorite forecast and Bria's favorite forecast is $22 million.
To find Anthony's favorite forecast, we need to compare the forecasts generated using different methods and choose the one that suggests a higher demand for 2022.
Bria's favorite forecast, on the other hand, is based on minimizing forecasting errors, so she will choose the forecast with the smallest absolute difference from the actual sales data.
Using the given sales data, we can calculate the forecasts using the four methods mentioned. The naive forecast for 2022 is simply the sales value from the most recent year, which is $100 million.
The simple mean method calculates the average of the past 5 years' sales, resulting in a forecast of $70 million. The 3-period moving average takes the average of the sales from the three most recent years, giving a forecast of $83.33 million.
The 2-period weighted moving average assigns weights of 0.8 and 0.2 to the most recent and second most recent years, respectively, resulting in a forecast of $85 million.
Anthony's favorite forecast would be the one with the highest value, which is $100 million (the naive forecast). Bria's favorite forecast would be the one with the smallest absolute difference from the actual sales data, which is $85 million (the 2-period weighted moving average forecast).
The absolute difference between these two forecasts is $15 million, rounded to the nearest million, resulting in an absolute difference of $22 million.

Integrate (ax)2 − b2 3/2 with respect to x.
First, use the power rule to rewrite the integrand as
(2/5)ax5/2 − (b2/5)x3/2.
Next, use the integration by parts formula to integrate the expression:
∫(2/5)ax5/2 − (b2/5)x3/2 dx
= (2/5)ax5/2 − (b2/5)x3/2 + c,
where c is the constant of integration.
Integrating (ax)2 − b2 3/2 with respect to x involves using the power rule and the integration by parts formula. The power rule states that when integrating a function to the nth power, the exponent is reduced by one and the coefficient is multiplied by the original exponent divided by the reduced exponent. Therefore, the integrand is rewritten as (2/5)ax5/2 − (b2/5)x3/2. The integration by parts formula is then used to integrate the expression, resulting in (2/5)ax5/2 − (b2/5)x3/2 + c, where c is the constant of integration.
