The equation in slope-intercept form is y = (-2/5)x - 9/2.

Slope-intercept form is an equation of a line that is written in the form of y=mx+b, where m is the slope of the line and b is the y-intercept. The slope-intercept form makes it easy to identify the slope and y-intercept of a line from an equation.

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Therefore, for a line with a slope of −2/5 that passes through the point (15, −9/2), we can solve for b using the point-slope formula.
Point-slope formula:  y - y1 = m(x - x1)
Plugging in the given information, we get:
-9/2 - (-9/2) = (-2/5) (15 - 15)
Solving this equation yields b = -9/2.
Therefore, The equation in slope-intercept form is y = (-2/5)x - 9/2.

The statement '15 more than the sum of 5 and a number' is equivalent to the mathematical expression (5+n)+15.

Therefore the answer is (5+n)+15.

The statement "15 more than the sum of 5 and a number" is asking for an expression that represents the value that is 15 greater than the result of adding 5 and a number together. The mathematical way to express this is:

15 + (5 + n)

Where n is the number that we are adding to 5.

15 is being added to the sum of 5 and n. The parentheses around the 5 and n indicate that those two values are being added together before the 15 is added to them.

The intersection point is the location on the y-axis where the slope of the line crosses. where the y-axis crosses that point on a line or curve. By using y = mx+c as the equation for the straight line, where m stands for the slope and c for the y-intercept, this is proven. The slope (m) and y-intercept (b) of the line are denoted in the intercept form of the equation. For equations of the intercept form (y=mx+b), the slope and y-intercept, respectively, are m and b. Furthermore, some equations may be rewritten to appear as slope intercepts. For instance, the slope and y-intercept change to 1 and 0 respectively when y=x is represented as y=1x+0.

In general, a larger sample size is more likely to represent the population than a smaller sample size. This is because a larger sample size increases the chances that the sample will be representative of the population.

When the sample size is that larger, there is a lower chance of getting a skewed or biased sample. A larger sample size also tends to have less variability in the sample statistics, making it more likely to provide accurate estimates of population parameters.

However, it is important to note that increasing the sample size does not guarantee that the sample is representative of the population. The sampling method used, and the way the sample is selected, can also have an impact on the representativeness of the sample.

Hence, surveying 100 students is more likely to represent the population than surveying a smaller sample size like 10 students, but it does not guarantee a perfect representation of the population.

Although there are other factors to take into account, a model is worth your attention if its R-Squared is more than 0.6: R-squared values lower than 0.5 are normal for any science that tries to predict human behavior, such as psychology.

There are multiple phases involved in the actual R-squared computation. Finding the line of best fit, frequently from a regression model, entails taking the data points (observations) of dependent and independent variables.

Predicted values would then be calculated, actual values would be subtracted, and the results would be squared.

You would deduct the average actual value from each of the actual values, square the findings, and add them to determine the overall variance.

The R-squared is obtained by dividing the first sum of mistakes (unexplained variance) by the second sum (total variance) and deducting the result from one.

Direct variation is a type of proportionality in which one quantity directly varies with respect to a change in another quantity. This means that if one quantity increases then the other quantity will also experience a proportionate increase.

Similarly, if there is a decrease in one quantity then the other quantity also decreases. Direct variation is a linear connection hence, the graph will be a straight line. Further, if the two entities are in a direct variation relationship then one will be a constant multiple of the other.

Answer: To find out which loan option will have the least interest, you need to calculate the interest amount for each option. You can do this by using the formula:

Interest = Principal x Interest Rate x Time (in years)

For option A, the interest amount would be:

Interest = $12,000 x 0.05 x (48/12) = $2,400

For option B, the interest amount would be:

Interest = $12,000 x 0.045 x (60/12) = $3,000

For option C, the interest amount would be:

Interest = $12,000 x 0.0375 x (66/12) = $2,970

For option D, the interest amount would be:

Interest = $12,000 x 0.04 x (72/12) = $3,840

For the fixed base(10), if the exponent decrease by 1, the number will becomes one-tenth of the previous number.

The Power Rule for Exponents is (a^m)^n = a^m*n. To increase a number with an exponent to a power, we need to multiply the exponent times the power. Negative Exponent Rule is x^-n = 1/x^n. We need to invert the base to change a negative exponent into a positive.

Exponents are used to represent repeated multiplication of a number by itself. For example, 7 * 7 * 7 can be showed as 73. Here, the exponent is 3 that stands for the number of times the number 7 is multiplied. The base here is 7 that is the actual number which is getting multiplied.

A linear function is one that visualizes a straight line on the coordinate plane.

When the independent variable (often 'x') varies by a constant amount and the dependent variable (typically expressed by 'y') changes by a constant amount, the function is said to be linear. A linear function is, for instance, the progression in the number of ticks of a clock's second hand through time.

Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 indicates a straight line on a coordinate plane, indicating that it is a linear function. This function can be expressed as f(x) = 3x - 2 since f(x) can take the place of y.

The average rate of change of the given function is 20.

It quantifies how much the function changed per unit on average throughout that time interval. The slope of the straight line connecting the interval's ends on the function's graph is used to calculate it.

The average rate of change of a function f(x) over the interval [a,b] is given by the formula:

(f(b) - f(a)) / (b - a)

So, for the function f(x) = x² + 2 as x changes from 5 to 15, we can plug in the values to find the average rate of change:

(f(15) - f(5)) / (15 - 5) = (15² + 2 - 5² - 2) / (15 - 5) = (225 - 25) / 10 = 200 / 10 = 20
