The explanatory variable is the player's weight and the response variable is the player's 40-yard dash when 40-yard dash more slowly than lighter players.

Given that,

Football instructors who oversaw summer sessions noted that heavier players often ran the 40-yard dash more slowly than lighter players.

We have to find what are the relationship's explanatory variable and response variable.

We know that,

We must determine what is causing the player's slower times.

The players' slower times are a result of their added weight.

So,

The player's weight is the explanatory variable, while their 40-yard dash time is the response variable.

To find maximum value and minimum value in a set we have to use ven diagram from set theory.

Here we are taking an example?

Let A and B be 2 sets having elements 4 and 7 respectively. Then write the maximum number of elements that A∪B can have.

Let us assume that:

Number of elements of A is equal to n (A).

Number of elements of B is equal to n (B).

Number of elements of A∩B is equal to n (A∩B).

Now, the formula for the elements of A U B is as follows:

n(A∪B)=n(A)+n(B)−n(A∩B)

It is given in the question that, number of elements in set A is equal to 4 and number of elements in set B is equal to 7. So, we can write:

n (A) = 4, n (B) = 7

n (A∩B): the number of elements which are common in both the sets A and B.

We have to find the maximum number of elements which are in n(A∪B). So, the maximum of n(A∪B) is when n(A∩B) is minimum and the minimum of n(A∩B) is 0.

n(A∪B)=n(A)+n(B)−n(A∩B)⇒n(A∪B)=4+7−0⇒n(A∪B)=11

Hence, the maximum number of elements in A∪B is 11.

Note: You might be wondering, why for maximizing the n (A∪B) we have to minimize n (A∩B) and why the minimum value of n (A∩B) is 0.

In the formula for n (A∪B),

n(A∪B)=n(A)+n(B)−n(A∩B)

L.H.S will be maximized when in the R.H.S; the term after minus sign will be minimized. Hence, n (A∩B) must be minimized.

The minimum possible value of n (A∩B) is 0 means that the elements in the set A and B are such that there is not a single element is common in both the sets. And it could be possible that we have two sets and the sets have no element in common.

When no elements is common in both the sets, the n (A∩B) is ∅.

The set which has no element in it is called a null set or an empty set.

By this we can find maximum and minimum value in a set.

If the value of the variable 'x' is 12. Then the measure of the angle ∠B will be 118°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

In triangle ΔABC, ∠B = (12x − 26)°, and the measure of the exterior angle to ∠B is (7x − 22)°.

The sum of the interior and exterior angles will be 180°. Then the equation is given as,

(12x − 26)° + (7x − 22)° = 180°

12x - 26 + 7x - 22 = 180

19x - 48 = 180

19x = 228

x = 12

Then the measure of the angle ∠B will be given as,

∠B = 12 (12) - 26

∠B = 144 - 26

∠B = 118°

y n d ∝ 1 y n

As they have inverse relation.

So the if we increase the distance between the two source lights then the location of the maxima will decrease.

Step-by-step explanation:

The 6th term of the geometric progression is given by a₆ = 729 / 16

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the 6th term of the geometric progression be a₆

Now , the first term of the GP is a₁ = 6

Let the second term of the GP be a₂ = 9

So , the common ratio of the GP is r = second term / first term

Substituting the values in the equation , we get

The common ratio r = 9/6 = 3/2

Now , the 6th term of the geometric progression a₆ = arⁿ⁻¹

On simplifying the equation , we get

The 6th term of the geometric progression a₆ = 6 ( 3/2 )⁵

The 6th term of the geometric progression a₆ = 6 ( 243 / 32 )

The 6th term of the geometric progression a₆ = 729 / 16

The best interpretation of this slope is A. On average, each 1-centimeter increase in foot length was associated with a 5.89-centimeter increase in shoulder height.

The elephants of Kruger would need to be continuously culled until the habitats began to recover, at which point the reduced population numbers would need to be maintained until the vegetation had recovered to a near-climax state in order to determine that number.

The average change in the response (y) variable that is associated with a change of one unit in the explanatory (x) variable is shown by the slope of the regression line.

In this instance, the slope represents the average change in shoulder height caused by an increase in foot length of one centimeter.

Slope = ∆Y/∆X = change in Y per unit change in X = 5.89

To draw a dilation with a scale factor 1/2 , multiple every coordinates of pre-image with 1/2 and join the obtained points

A dilation is a transformation that alters the size of an image.

There is a centre and a scale factor in all dilations. The centre serves as the dilation's reference point (like the vanishing point in a perspective drawing)

The scale factor indicates how much the figure expands or contracts. A scale factor is usually denoted by the letter "k," and it is always greater than zero.

To draw a dilation with a scale factor of 1/2, follow these steps:

Step 1: Determine the scale factor and the dilation centre.

Step 2: Identify an image vertex. Draw a line through one of the image's vertices from the center of dilation.

Step 3: Find the horizontal distance and the vertical distance between the center of dilation and the vertex.

To find the horizontal and vertical distances from the centre of dilation to a new vertex, multiply the distances by the scale factor 1/2.

Step 4: Determine the new horizontal and vertical distances from the centre of dilation. Make a point plot.

Step 5: Join the new vertices together to create the dilated image.
