The diameter of the small volcano 'Pico' would be = 8km

An isoline is defined as the line found on a map that has constant value of either distance, temperature or rainfall.

The isoline that is used in the given map above = 2000m.

The number of lines that surrounds the pico volcano = 4

Therefore the diameter of the volcano = 2000×4 = 8000m

But 1000m = 1km

Let (h, k) be the vertex of the given parabola.

From the graph value of the vertex is equal to :

(h ,k)=(1, -4)

h represents the x-coordinate.

k represents the y-coordinate.

y-coordinate represents the maximum value of the parabola.

Sample is used more often than a population as B. It is usually impossible to count the entire population

In many cases, it is not practical or possible to gather data from every member of a population. For example, imagine trying to survey the purchasing habits of every single adult in the United States. It would be incredibly time-consuming, costly, and difficult to reach everyone.

Instead, researchers use a sample, which is a smaller group of individuals chosen from the population. By analyzing the data from a sample, researchers can make inferences about the population as a whole.

Therefore, the correct option is B.

The choice c is correct When a modeling technique is referred to as a "black box," it means that the equation that develops within the model cannot be understood.  

A model known as a "black box" is one in which the model's internal workings or logic are not readily apparent to the user. All in all, the model takes in data sources and delivers yields, yet the middle of the road steps or computations included are stowed away from the client.

This absence of interpretability makes it trying to comprehend how the model shows up at its expectations or choices. In complex machine learning algorithms like neural networks, where accuracy is prioritized over understanding the underlying mechanisms, black box models are frequently utilized.

The value of x that satisfies the equation 45 - 3x = 1256 is approximately -403.6666667.

To solve the equation 45 - 3x = 1256, we want to isolate the variable x on one side of the equation. This can be done by performing a series of mathematical operations that maintain the equality of the equation.

Start by combining like terms on the left side of the equation. The constant term, 45, remains as it is, and we have -3x on the left side. The equation becomes:

-3x + 45 = 1256

To isolate the variable x, we need to move the constant term to the right side of the equation. Since the constant term is positive, we'll subtract 45 from both sides of the equation to eliminate it from the left side:

-3x + 45 - 45 = 1256 - 45

Simplifying, we have:

-3x = 1211

To solve for x, we want to isolate the variable on one side of the equation. Since the variable x is currently being multiplied by -3, we can isolate it by dividing both sides of the equation by -3:

(-3x) / -3 = 1211 / -3

The -3 on the left side cancels out, leaving us with:

x = -403.6666667

Answer:

9.7959 sec

Step-by-step explanation:

For the arrow to reach the same height as the bow again, - 4.9x^2+48x=0, 48=4.9x, x=48/4.9=9.7959

The time arrow take to come back to a height even with his bow height is 9.79 seconds.

We have an equation of the height of the arrow with respect to time -\(y = -4.9x^{2} +48x\) where y is the height of the arrow in meters above Andrew's bow and x is the time in seconds since Andrew shot the arrow.

We have to find out - how long it takes the arrow to come back to a height even with his bow height.

It is an example of two - dimensional Projectile motion.

We have the function that depicts the variation of height of the arrow with respect to time given by -

\(y=-4.9x^{2} +48x\)

To find the time taken by the arrow to come to a height even with his bow height, we should equate y = 0.

\(y=-4.9x^{2} +48x=0\\-4.9x(x-9.79)=0\\-4.9x=0\;\;\;and\;\;\;x-9.79=0\\x =0\;\;\;and\;\;\;x=9.79\)

Time cannot be 0, hence the time arrow take to come back to a height even with his bow height is 9.79 seconds.

The least upper bound (LUB) of a nonempty subset s of the real numbers (r) is a number m such that:
1. m is an upper bound of s, i.e., m ≥ x for all x ∈ s;
2. m is the least upper bound, i.e., if u is any upper bound of s, then u ≥ m.

To prove that the LUB of a nonempty subset s of r is unique, we need to show that if m and n are both LUBs of s, then m = n.

Assume that m and n are both LUBs of s. Since m is a LUB, we have that:
1. m is an upper bound of s, i.e., m ≥ x for all x ∈ s;
2. m is the least upper bound, i.e., if u is any upper bound of s, then u ≥ m.

Similarly, since n is a LUB, we have that:
1. n is an upper bound of s, i.e., n ≥ x for all x ∈ s;
2. n is the least upper bound, i.e., if u is any upper bound of s, then u ≥ n.

Now, suppose for contradiction that m ≠ n. Without loss of generality, assume that m < n. Since m is an upper bound of s, we have that m < n is not an upper bound of s. Therefore, there exists some element x in s such that m < x ≤ n. But this contradicts the fact that n is an upper bound of s. Therefore, our assumption that m ≠ n must be false, and we conclude that m = n.

We have shown that if m and n are both LUBs of a nonempty subset s of r, then m = n. Therefore, the LUB of s, if it exists, is unique.

We may draw a scatterplot of the data and compute the correlation coefficient to see whether there is a relationship between Nadeem's visits to the library and the number of books he checks out. Linear Equation = Y =mx+c. Option A is Correct.

The degree and direction of the linear link between two variables are measured by the correlation coefficient. If the correlation is positive, it suggests that if one variable rises, the other variable rises as well.

If there is a correlation, linear regression may be used to describe the data with a linear equation.

Y= mx+c

Based on how frequently Nadeem visits the library, we may use this equation to anticipate how many books he will borrow. Correlation does not always indicate cause, though. Option A is Correct.
