Answer: 3x^2 - 16x + 15
Step-by-step explanation:
5x * 3x = 15x^2
-7 * 3x = -21x
5x * 1 = 5x
-21x + 5x = -16x
5x^2 - 17x^2 + 15x^2 = -12x^2 + 15x^2 = 3x^2
13x - 7x - 22x = 6x - 22x = -16x
- 4 + 19 = 15

Ansley and Maria were baking a birthday cake. The recipe called for 234cup of flour. Both girls took turns pouring in the flour. Maria poured in 124cup of flour into the mixing bowl and then Ansley poured in the remaining amount.
Answer:
Step-by-step explanation:
To find out how much flour Ansley poured into the mixing bowl, we need to subtract the amount Maria poured from the total required amount.
Total amount of flour required = 2/3 cup
Amount Maria poured = 1/4 cup
To find the remaining amount poured by Ansley, we can subtract:
Remaining amount = Total amount required - Amount Maria poured
Remaining amount = 2/3 cup - 1/4 cup
To simplify the calculation, we need a common denominator. Let's convert 2/3 to have a denominator of 12:
Remaining amount = (8/12) cup - (3/12) cup
Remaining amount = 5/12 cup
Therefore, Ansley poured 5/12 cup of flour into the mixing bowl.

take a file name to read input data from keybaord (do not hardcode into it into your program
the user instead of hardcoding it into your program. This can be done by using the input function to prompt the user to enter the file name.
For example, you can use the following code:
```
filename = input("Enter the file name: ")
```
This will allow the user to enter the name of the file they want to read input data from.
The input function in Python allows you to prompt the user to enter a value. In this case, we are prompting the user to enter the name of the file they want to read input data from. Once the user enters the file name, it is stored in the variable 'filename'. This variable can then be used to read data from the specified file. By taking the file name as input from the user, you make your program more flexible and allow it to work with different input files without having to modify the code each time.

The symbolic equation A = kB3 means which of the following
a. A is proportional to the cube of B.
b. B is proportional to the square of A.
c. A is proportional to the square of B.
d. B is proportional to the cube of A.
The symbolic equation A = k\(B^3\) signifies that A is directly proportional to the cube of B. This means that as the value of B increases, the value of A will increase by a factor equal to the cube of B.
The symbolic equation A = k\(B^3\) indicates that A is directly proportional to the cube of B. This means that as the value of B increases, the value of A will increase by a factor equal to the cube of B. Conversely, if the value of B decreases, A will decrease accordingly, following the cube of B.
In other words, if we were to double the value of B, A would increase by a factor of 8 (\(2^3\)), and if we were to triple the value of B, A would increase by a factor of 27 (\(3^3\)). This relationship holds true for any positive real values of B.
To understand this concept better, consider an example where A represents the volume of a cube and B represents the length of its side. If we increase the length of the side (B) by a factor of 2, the volume (A) will increase by a factor of 8 since the volume of a cube is calculated by multiplying the length of the side three times (A = \(B^3\)).
Therefore, option a. A is proportional to the cube of B is the correct interpretation of the symbolic equation A = k\(B^3\).

Aslam and akram invested rs 27000 and rs 30000 to start a business . if they earned a profit of rs 66500 at the end of the year , find the profit of each one
The profit of Aslam is Rs. 31,474.50 and the profit of Akram is Rs. 35,025.50.
To find the profit of each person, we can use the concept of ratios.
First, let's find the total investment made by both Aslam and Akram:
Total investment = Aslam's investment + Akram's investment
Total investment = 27000 + 30000 = 57000
Next, let's calculate the ratio of Aslam's investment to the total investment:
Aslam's ratio = Aslam's investment / Total investment
Aslam's ratio = 27000 / 57000 = 0.4737
Similarly, let's calculate the ratio of Akram's investment to the total investment:
Akram's ratio = Akram's investment / Total investment
Akram's ratio = 30000 / 57000 = 0.5263
Now, we can find the profit of each person using their respective ratios:
Profit of Aslam = Aslam's ratio * Total profit
Profit of Aslam = 0.4737 * 66500 = 31474.5
Profit of Akram = Akram's ratio * Total profit
Profit of Akram = 0.5263 * 66500 = 35025.5
Therefore, the profit of Aslam is Rs. 31,474.50 and the profit of Akram is Rs. 35,025.50.

In this case, the proportion (79%) only applies to the sample of 481 consumers and thus it is a statistic because it represents the sample.
The distinction between a parameter and a statistic is that a parameter refers to a sample property, but a statistic is referred to as a population distribution characteristic.
For instance, a population mean is a parameter, but a sample mean is a statistic.

Which of the following statements is true about the slope of the least squares regression line when the correlation coefficient is negative? a. The slope is negative. b. The slope is positive. C. The slope is zero. d. Nothing can be said about the slope based on the given information
The statement "a. The slope is negative" is true about the slope of the least squares regression line when the correlation coefficient is negative.
When the correlation coefficient is negative, it indicates an inverse relationship between the two variables. In a linear regression, the slope of the line represents the direction and magnitude of the relationship between the independent and dependent variables. A negative correlation coefficient indicates that as the independent variable increases, the dependent variable decreases. Therefore, the slope of the least squares regression line will also be negative.
The slope of the regression line is calculated using the formula: slope = correlation coefficient * (standard deviation of y / standard deviation of x). Since the correlation coefficient is negative and the standard deviation of x and y are positive values, multiplying a negative correlation coefficient by positive standard deviations will result in a negative slope. Hence, option "a. The slope is negative" is the correct statement.
