The slope of the line 4y - 3x = 1 is 3/4.

A line's slope is the ratio of how much y grows as x grows by a certain amount. You may determine a line's slope by looking at how steep it is or how much y grows as x grows. Anywhere along the line, the slope is uniform. In mathematics, measuring steepness is a common goal. It is obvious that slopes B and C are steeper than slope A. They both stand seven units tall, although slope A is only four. Therefore, it would seem that steepness and height are related.

Given

The length of the arc of the curve from point p to point q is 14.

The length of the arc is calculated by using the differentiation of the curve expression.

Here we have given that expression y = 1/2 x²

And we need to find the length of the arc from the point P to Point Q.

In order to find the length we have to extract the x values from the given point then we get,

(x1, x2) = (-7, 7)

Here we have the curve of the arc as,

=> y = 1/2 x²

Now, we have to differentiate the expression to find the solution,

=> length of arc = ∫₋₇⁷1/2 x²

=> length of arc = 1/2 ∫₋₇⁷ x²

=> length of arc = 1/2 [2x]₋₇⁷

When we apply the values on x, then we get,

=> length of arc = 1/2 [2(7) - 2(-7)]

=> length of arc = 1/2 [28]

The central limit theorem establishes that, in many situations, when independent random variables are summed up, their properly normalized sum tends toward a normal distribution even if the original variables themselves are not normally distributed.

We have,

A. It's exactly normal because both populations are normally distributed.

B. It's approximately normal because both sample sizes are at least 30.

C. It's skewed, because the populations are skewed, and both sample sizes are at least 30.

D. The shape cannot be determined since we don't know the shape of either population distribution.

Option (B) is true, as the sample size is more than 30 and according to the central limit theorem, with a sample size of more than 30, approximately normal distribution.

Step-by-step explanation:

remember some of the angle theorems inside a circle.

first of all, arc angles are the angles of the corresponding circle segments at the center of the circle (the angle between the lines from the points on the arc to the center).

and, of course, all the arc angles together around a circle are therefore 360°.

so,

(8x + 20) + 104 + arc angle KJP = 360

and then :

the opposite angle is half of the arc angle for the same points on the circle arc.

angle L = 5x + 1 is the opposite angle of K and P, and that is therefore half of the arc angle KJP.

5x + 1 = (arc angle KJP)/2

arc angle KJP = 2×(5x + 1)

and by using this in the first equation we get

(8x + 20) + 104 + 2×(5x + 1) = 360

8x + 124 + 10x + 2 = 360

18x + 126 = 360

18x = 234

x = 234/18 = 13

The types of continuity of a function are: pointwise continuity, uniform continuity, absolute continuity, and uniform convergence.

The types of continuity of a function are: pointwise continuity, uniform continuity, absolute continuity, and uniform convergence. Pointwise continuity means that the function is continuous at each point in its domain. Uniform continuity means that the function is continuous over some larger region. Absolute continuity means that the function is continuous over its entire domain. Finally, uniform convergence means that the function converges to a limit value over a range of values. Pointwise continuity is the weakest form of continuity and uniform convergence is the strongest.
