you're ordered to attempt to memorize a series of images. there are 15 images in the series. when you are asked to state the order of the images you remember the first 3 and then it starts to get fuzzy. This is an example of memory retrieval.

What do you mean by series?

The total of a particular sequence of terms is known as a series in mathematics. These phrases often refer to real or complex numbers, though considerably more generality is possible.

In calculus and its generalization, mathematical analysis, the study of series plays a significant role. Most mathematical disciplines employ series, including combinatorics, where generating functions are employed to explore finite structures.

Along with being widely utilized in mathematics, infinite series are also frequently employed in other quantitative fields like physics, computer science, statistics, and finance.

By evaluating the function we will see that the difference is:

f(1) - f(-7)  = 3

Here we have a piecewise function, this is a function that behaves differently on different intervals of its domain.

On the image you can see the different pieces of the function, and on the right the domain of each of the pieces.

The first part works for all the values smaller than -4 and x = -4.

So if we want to evaluate the function in x = -7, we need to use that piece:

f(-7) = |-7 + 5| - 9 = -7

And the second piece works on the interval (-4, 1], so to evaluate in x = 1 we need to use that piece.

f(1) = -1³ - 3*1 = -4

Then the difference is:

f(1) - f(-7) = -4 + 7 = 3

Assuming the weight and magnitude of the person, we can conclude that the weight of the person is 491N.

The magnitude or size of a mathematical object determines whether it is larger or smaller than other objects of the same kind in mathematics.

Formally speaking, the magnitude of an object is the visible outcome of an ordering—of the class of objects to which it belongs.

So, the weight of the person will be:

The scale measures the passenger's normal upward force as it is applied by the floor.

When moving upward, the most force is generated (when starting an upward trip or ending a downward trip).

When there is a downhill acceleration, the normal force is at its lowest.

For any such circumstance:

∑F y​ =ma y  becomes for starting  +591N−mg=+ma and for stopping      +391N−mg=−ma.

Where a stands for the acceleration's magnitude.

To get rid of a and find mg, add these two simultaneous equations:

+591N−mg+391N−mg=0

OR

982N–2mg=0

Fg​ = mg = 982N/2​ = 491N

Therefore, assuming the weight and magnitude of the person, we can conclude that the weight of the person is 491N.

The  correct one is Your cousin. If the line is vertical, it will not have a slope.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

So, from the Discussion we came to know about Vertical Line.

But the slope of vertical line is undefined.

Then, the slope intercept form is not possible in vertical line.

Step-by-step explanation:

The number of days that the second voyage last's is 480 days.

Given,

The discrepancy in the length of the two excursions, we are asked to determine how many days the second voyage lasted.

We initially assign variables in order to overcome this issue. Let the duration of the first cruise be f days and the duration of the second expedition be s days.

We are aware that the first journey lasted 43 days longer than the second.

In mathematics, f = 43 plus s. (I)

The cumulative duration of the two journeys was 1003 days. Mathematically:

f + s = 1003........(ii) (ii)

We transform I into ii

43 + s + s = 1003

43 +2s = 1003

2s = 1003 - 43

2s = 960

s = 960/2 = 480 days

That is,

The second voyage lasted about 480 days

Using the numbers to indicate their locations as pairs of x and y values. Euclidean distance is used to measure all distances.

a. Using the k-means algorithm, we can group the points into three clusters based on their initial cluster centers. The first cluster consists of the points (18, 10), (21, 11), (22, 22), (24, 15), (26, 12), and (26, 13), the second cluster consists of the points (27, 14), (40, 27), (41, 29), (42, 20), and (44, 28), and the third cluster consists of the points (30, 33), (31, 39), (35, 37), (39, 44), (46, 21), (47, 30), (48, 31), and (49, 23).

The silhouette approach, which compares how similar each point is to the points in its own cluster to the points in other clusters, can be used to assess the quality of the clusters. A high silhouette value denotes a well-clustered point, while a low silhouette value denotes a possible incorrect cluster assignment.

b. In hierarchical agglomerative clustering, we first create individual clusters for each point, which are then combined to create a single cluster that contains all of the points. Depending on how they calculate the separation between clusters, the three distinct link approaches will result in a variety of clustering outcomes.

The minimal distance between any two points in each of the two clusters is used by single link to calculate the separation between the clusters. Because it only takes into account the closest pair of points, this can lead to long, thin clusters.

The distance between the clusters is calculated using the maximum distance between any two points in the two clusters. Due to the fact that it only takes into account the farthest pair of points, this can lead to compact, spherical clusters.

The average link calculates the separation between the two clusters by averaging out all of the distances between the points in the two clusters. This takes into account all possible pairs of points and may lead to clusters with more symmetrical shapes.

In general, a single link will create clusters that are the most compact, a complete link will create clusters that are the most spherical, and an average link will create clusters that are more evenly shaped.

The time that runner takes to finish the race is 2.133 minutes.

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The speed of the runner is given as 3/8 miles per minute.

The remaining distance to be travelled is 7/8 miles.

Then, the time taken by the runner is the ratio of distance to be travelled to the speed. It can be written as follows,

Time taken by runner = (7/8)/(3/8)

                                    = 7/3

The probability of obtaining between 70 and 82 tails is 0.2137, that is, option A.

Here, we are given that a fair coin is tossed 130 times.

Thus,

number of trials ⇒ n = 130

p = P(getting tails in a single toss) = 0.5

mean of a binomial distribution = np

= 130*0.5

= 65

variance = np(1-p)

= 65*0.5

= 32.5

standard deviation = sqrt(variance)

= sqrt(32.5)

= 5.7

Now, x = number of tails

X follows a normal distribution with mean 65 and variance 5.7

P(70 < x < 82)

= P( 69.5 < X < 82.5)  [applying continuity correction]

= P[(69.5-65)/5.7 < Z < (82.5-65)/5.7)]

= P(0.79 < Z < 3.07)

= P(Z < 3.07) - P(Z < 0.79)

= 0.9989- 0.7852

= 0.2137

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

12 - 15 = 9 - 12 = 6 - 9 = - 3

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 15 and d = - 3 , then

Maximum area to enclose a rectangular pasture with one side up against a river is equal to 500,000 square feet.

As given in the question,

Let 'l' be the length of the rectangular pasture

And 'w' be the width of the rectangular pasture

Condition:

One side of the pasture is up against a river

Perimeter of the rectangular pasture with one side up against river = l + 2w

⇒ 2000 = l + 2w

⇒ l = 2000 - 2w

Area of the rectangular pasture

=( 2000 - 2w )( w )

= - 2 ( w² - 1000w )

= -2( w² - 1000w + 250000 - 250000 )

= -2 ( w - 500 )² + 500, 000

Maximum area is at w = 500

Maximum area is 500,000
