Answer:
it is: y=2x-4
The equation in the form of slope intersect will be "4x - 2y = 8".
Slope of line:The Slope-Intercept formulation of such an equation seems to be critical for graphing as well as understanding the linear problems.
Users can rapidly get the slope as well as y-intercept of something like a line when we have a linear equation throughout the slope-intercept form. This permits us to visualize it as well.
According to the question,
The points are:
(x₁, y₁) = (0, -4)
(x₂, y₂) = (2, 0)
We know the formula,
→ \(\frac{y-y_1}{y_2-y_1} = \frac{x-x_1}{x_2-x_1}\)
By substituting the given points, we get
\(\frac{y-(-4)}{0-(-4)} = \frac{x-0}{2-0}\)
\(\frac{y+4}{4} = \frac{x}{2}\)
By applying cross-multiplication, we get
2(y + 4) = 4x
2y + 8 = 4x
4x - 2y = 8
Thus the above approach is right.

Answer:
g = 68
Step-by-step explanation:
g/4 + 11 = 28
subtract 11 from both sides:
g/4 + 11 - 11 = 28 - 11
g/4 = 28 - 11
g/4 = 17
multiply both sides by 4:

I wish to accumulate $100 000 over 20 years at 10% p.a. compounded annually. What should be the amount of my annual payments?
To accumulate $100,000 over 20 years at a 10% annual interest rate compound annually, you would need to make annual payments of $8,218.64.
You can use the formula for the future value of an annuity to accumulate $100,000 over 20 years at a 10% annual interest rate compound on a yearly basis:
\(FV = Pmt * [(1 + r)^n - 1] / r\)
Where:
FV is future value, which is $100,000 in that case
Pmt: annual payment
r: annual interest rate, which is 10%
n: number of payment periods, which is 20
By plugging in values:
\($100,000 = Pmt * [(1 + 0.1)^(20) - 1] / 0.1\)
Solving for Pmt, we get:
\(Pmt = $100,000 / [(1 + 0.1)^(20) - 1] / 0.1\\Pmt = $100,000 / 12.167\\Pmt = $8,218.64\)

suppose a population was normally distributed with a mean of 10 and standard deviation of 2 . What proportion of the scores are below 12.5? Choose the correct answer 75% 77.8% 92% 89.44% Cannot be calculated
The proportion of scores below 12.5 in a normally distributed population with a mean of 10 and a standard deviation of 2 can be calculated using the Z-score and the standard normal distribution table. In this case, we need to find the area under the curve to the left of the value 12.5.
The Z-score is calculated as (X - μ) / σ, where X is the value we want to find the proportion for, μ is the mean, and σ is the standard deviation. Substituting the given values, we have (12.5 - 10) / 2 = 1.25.
Using the standard normal distribution table or a statistical calculator, we can find that the area to the left of a Z-score of 1.25 is approximately 0.8944. Therefore, the proportion of scores below 12.5 is approximately 89.44%.
In a normal distribution, the Z-score measures the number of standard deviations a value is from the mean. By calculating the Z-score for the value 12.5, we can use the standard normal distribution table to find the proportion of scores below that value.
The table provides the cumulative probability up to a certain Z-score. In this case, the Z-score of 1.25 corresponds to a cumulative probability of approximately 0.8944.
Since the normal distribution is symmetric, the proportion of scores above 12.5 is equal to the proportion below the mean minus the proportion below 12.5.
Hence, subtracting 0.8944 from 1 (or 100%) gives us approximately 0.1056 or 10.56%. Therefore, the proportion of scores below 12.5 is approximately 89.44%.

The test statistic equals _____, the p-value is______
Given the above, complete the following: If the test is done at a .01 level of significance, the null hypothesis should _________________________ (write clearly whether rejected or accepted and why?)
The test statistic equals 2.55 and the p-value is 0.0054. If the test is done at a 0.01 level of significance, the null hypothesis should be rejected because the p-value (0.0054) is less than the significance level (0.01). This indicates strong evidence against the null hypothesis.
B. To calculate the test statistic, we first find the standard error of the mean (SEM), which is equal to σ/√n. Plugging in the given values, we get SEM = 2. Therefore, the test statistic can be calculated using the formula:
t = (x-bar - μ) / SEM = (24.6 - 20) / 2 = 2.3.
Since we have a one-tailed test (Ha: μ > 20), we need to find the p-value for the upper tail. Using a t-distribution table or calculator, with 35 degrees of freedom, we find the p-value to be 0.011.
Comparing the p-value to the significance level, we see that 0.0054 < 0.01, indicating strong evidence against the null hypothesis.
Therefore, we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the population mean is greater than 20.

The roots of the given polynomial function is {-4, -2, -3 + 2i, -3 - 2i}.
How to get the roots of the polynomial?Here we have the polynomial function:
\(f(x) = (x^2 + 6x + 8)*(x^2 + 6x + 13)\)
So we just need to find the roots of the two quadratic functions, to do that, we use Bhaskara's formula.
For the first one, we have:
\(x = \frac{-6 \pm \sqrt{6^2 - 4*8} }{2} \\\\x = \frac{-6 \pm 2}{2}\)
So the two solutions are:
x = (-6 - 2)/2 = -4
x = (-6 + 2)/2 = -2
For the second quadratic we have:
\(x = \frac{-6 \pm \sqrt{6^2 - 4*13} }{2} \\\\x = \frac{-6 \pm 4i}{2}\)
So the two solutions are:
x = -3 + 2i
x = -3 - 2i
Finally, the list is:
{-4, -2, -3 + 2i, -3 - 2i}

true/false: a base class cannot contain a pointer to one of its derived classes.
The statement a base class cannot contain a pointer to one of its derived classes is false because a base class can indeed contain a pointer to one of its derived classes.
In object-oriented programming, a base class can have a pointer to one of its derived classes. This is known as upcasting or polymorphism. Upcasting allows for the flexibility of treating derived class objects as instances of the base class.
By using pointers, a base class can refer to derived class objects and access their member functions and variables. This enables the base class to work with different derived classes without needing to know their specific types.
Pointers to derived classes can be stored in base class member variables or passed as function parameters. This allows for dynamic binding and the ability to invoke overridden functions based on the actual derived class type at runtime.
This concept is fundamental to achieving polymorphism and code reusability in object-oriented programming languages like C++ and Java. It facilitates the implementation of inheritance hierarchies and the ability to work with objects of different derived classes through a common base class interface.
