Which of the following numbers would best represent the slope for the trend line for the scatter plot shown below?
1/3
3
-1/3
-3
The slope for the trend line for the scatter plot shown is option B: 3.
What is slope?
A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
The first two data points obtained form the graph is -
(1,8) and (2,11)
The slope of a line can be found using the formula -
m = (y2 - y1) / (x2 - x1)
Substitute the values into the equation -
m = (11 - 8) / (2 - 1)
Apply the arithmetic operation of subtraction -
m = 3 / 1
Apply the arithmetic operation of division -
m = 3
Therefore, the slope value is 3.

a right rectangular prism has length 44 cmcm, width 22 cmcm, and height 77 cmcm. if the length, width, and height are halved, what happens to the surface area?
If the length, width, and height of a right rectangular prism are halved, the surface area will be reduced by a factor of four.
The surface area of a right rectangular prism can be calculated by adding up the areas of all six of its faces.
To see why, consider that each of the original face's area was given by the product of two of the original dimensions. If each of those dimensions is halved, the area of each face is reduced to one-fourth of its original size. Because there are six faces, the total surface area is reduced by a factor of four.
In other words, if the original surface area was 2 * (44 cm * 22 cm + 44 cm * 77 cm + 22 cm * 77 cm) = 6176 square cm, the surface area of the halved rectangular prism would be 6176 square cm / 4 = 1544 square cm.

In linear equation, $ 1300 is the cost for 80 employees.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
Given that cost of a company picnic varies directly as the number of employees attending the picnic
Let "c" be the company picnic cost
Let "n" be the number of employees attending the picnic
Therefore,
cost ∝ number of employee attending picnic
c ∝ n
c = kn
Where "k" is the constant of proportionality
c = kn ---------- eqn 1
Given that company picnic costs $487.50 for 30 employees
Therefore substitute c = 487.50 and n = 30
487.50 = k(30)
k = 487.50/30
k = 16.25
Substitute n = 80 and k = 16.25 in eqn 1
c = 16.25(80)
c = 1300
Thus $ 1300 is the cost for 80 employees.

1. Solve for the missing sides of the right triangle. Round to the nearest hundredth. 29 50°
In order to solve for the missing sides of a right triangle, you need to use the Pythagorean Theorem.
Solve for the missing sides of the right triangle?The Pythagorean Theorem states that [tex]a^{2}+b^{2}=c^{2}[/tex], where a and b are the two shorter sides of the right triangle, and c is the longest side.In this case, we know that the longest side, c, is 29, and we know that the angle between the two shorter sides, a and b, is 50°.We can plug these values into the Pythagorean Theorem and solve for the missing sides. We get [tex]a^{2}+b^{2}=29^{2}[/tex], which simplifies to [tex]a^{2}+b^{2}=841[/tex].We can solve for a and b by taking the square root of both sides of the equation.Taking the square root of both sides, we get a = √([tex]841-b^{2}[/tex]). To find b, we can rearrange this equation to b = √([tex]841-a^{2}[/tex]).Plugging in a = 29, we get b = √(841 - [tex]29^{2}[/tex]) = √(841 - 841) = √0, which simplifies to 0.This means that the missing sides of the right triangle are a = 29, and b = 0.

On solving the provided question, we can say that the function is y = f(x) and (7.-6) and (7,3); nm = 3+6//-/7 => m = not defined
what is function?The subject of mathematics includes quantities and their variations, equations and related structures, shapes and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A connection between inputs and outputs in which each input leads to a single, distinct result is known as a function. Each function is given a domain and a codomain, or scope. Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, inside functions, and on functions.

Riemann Sum: A mathematical operation that involves splitting a region into rectangles and calculating the sum of the areas of the rectangles in order to estimate the area under a curve.
R: (3^3)(3) + (6^3)(3) + (11^3)(3) + (14^3)(3)
= 4,845 \sM: (3.5^3)(3) + (7.5^3)(3) + (11.5^3)(3) + (14.5^3)(3)
= 5,827.5
Riemann Sum is a numerical method for approximating the curve's area under the curve. To do this, the area is divided into rectangles, and the total of those areas is used. The product of the rectangle widths and the function evaluated at the sample locations is multiplied to determine the sum. The sample points may be taken at the rectangles' midpoints, right endpoints, or left endpoints.
In this instance, the partition points are at 3, 6, and 11 and we are computing the Riemann sum for f(x) = x3, 3 x 14. The Riemann total is 4,845, if the sample points are at 4, 9, and 12. The Riemann sum is 5,827.5 if the sample points are located at the midpoints of the rectangles. Because of this, the midpoint and endpoint Riemann sums are larger

given s/a = 4; l/a = 0.20; i/e = 0.10; a = l e and a = 100. find i/s.
The value of i/s is 0.02.
Now, According to the question:
"Information available from the question"
s/a = 4; l/a = 0.20; i/e = 0.10; a = l e and a = 100.
We have to find the i/s
We can first find the value of e, using the equation a = l + e, where l/a = 0.20 and a = 100:
e = a - (l/a) * a = 100 - (0.20 * 100) = 100 - 20 = 80
Next, we can find the value of i using the given information i/e = 0.10:
i = i/e * e = 0.10 * 80 = 8
Finally, we can find the value of i/S using the equation i/S = i / (S/a) * a = 8 / (4 * 100) = 8 / 400 = 0.02.
So, the value of i/S is 0.02.
