The volume of the figure shown in the reference attachment, provided hereby with the question statement will be 6786 ft³.

As per the question statement and the reference attachment, we are provided with a figure and its dimensions.

We are required to calculate the volume of the concerned figure using the dimensional values provided.

To solve this question, we need to calculate the volumes of the bottom cuboidal part, and the top pyramidal part separately, and then add these volumes, to obtain our final desired answer.

Given, the dimensions of the bottom cuboidal part is (21ft by 18ft by 13ft).

We know that, volume of a cuboid = (length * breadth * height).

Therefore, volume of our concerned bottom cuboidal part

= (21 * 18 * 13) ft³

= 4914 ft³.

Also given, the dimensions of the top pyramidal part are as follows,

Base of the triangle  = 18 ft,

Altitude of the triangle  = 16 ft,

and length of the pyramid = 13 ft.

Therefore, Volume of the concerned pyramid

= [(1/2) * base * altitude * length]

= [(1/2) * 18 * 16 * 13] ft³

= (9 * 16 * 13) ft³

= 1872 ft³.

Therefore, Total volume of the concerned figure shown in the reference  attachment, provided hereby with the question statement will be

(4914 + 1872) ft³ = 6786 ft³

The side length of the square that provides a counterexample to the statement square units in the area of a square is greater than or equal to the number of units in the perimeter is 2 Units.

A square is a kind of a 2D figure in which all the sides are equal.

We know that the absolute perimeter of a square is the sum of the lengths of all the total sides and as we see the area of a square is (side)².

Assuming that the whole square has four units completed for each side.

The square's circumference can be calculated as is 4 sides plus 4 fours, or as seen as 16 units.

Now the area of the square will be calculated as (4) ² = 16 sq units.

Now assuming that the total side length of the square about is 2 units.

The square's perimeter is calculated as (24) = 8 units, while its total area is calculated as (22) = 4 units.

∴ 2 units make up the side length that serves as a counterexample.

Basically, herein we have to determine the absolute numbers that when are multiplied by 4 are seen to be greater than it's square such numbers are 1, 2, 3.

The velocity of the cart b is found as 20/23 ft/s over the pulley.

For the given data in the question.

q's velocity is 2 feet per second.

Rope length is 39 feet.

Assume x is the distance between A and Q. (refer the image).

Assume y is the distance between Q and B. (refer the image).

As a result of the image,

x² + 12² = L²

Now, with respect to time t, differentiate the above equation.

2x(dx/dt) + 0 = 2L.(dL/dt)

For x = 5 ft and L = 13 ft

dL/dt = (5×2)/13 = 10/13

In the case of B,

y² + 12² = (39 - L)² ; from diagram.

Differentiating now,

2y(dy/dt) + 0 = -2(39 - L).(dL/dt)

At x = 5 ft and y = 23 ft.

dy/dy = -20/23

(A negative sign indicates the opposite direction)

Thus, the velocity of cart b is found as 20/23 ft/s.

√36 + ∛27

The irrational sums are:

π + 24

√8 + π

3/4 + √27

√16 + (-21/5)

= 4 + (-21/5)

= 4 - (21/5)

= (20 - 21) / 5

= - 1/5

= -0.2

Hence, the sum can be expressed as p/q so it is a rational number.

π + 24

= 3.1428571429 + 24

= 27.1428571429

The sum is non-terminating, so it is an irrational number.

√8 + π

= 2.82842712 + 3.1428571429

= 5.97128426

The sum is non-terminating, so it is an irrational number.

√4 + 5

= 2 + 5

= 7

The sum is an integer so it is a rational number.

√36 + ∛27

= 6 + 3

= 9

The sum is an integer so it is a rational number.

3/4 + √27

= 3/4 + 5.1961524227

= 0.75 + 5.1961524227

= 5.9461524227

Answer:

median = 9

range = 5

mode = 7

Step-by-step explanation:

median = 9 is in the middle of 10 and 8

range = 12 - 7

mode = there are 3 7s

Mode : the quantity that appears the most in a sequence
Because 7 is the number that appears the most ( 3 times ), it is the mode.

Range : the difference between the largest number and the smallest number
In this case, 12 is the biggest and 7 is the smallest -> Range = 5.

Median : the "middle number" (for example, if the sequence has 7 numbers, the 4th number will be the median. if the sequence has 8 numbers, the median will be the average of the 4th and 5th number, and of course from increasing order.)
There are 8 numbers in the sequence, from lowest to highest : 7,7,7,8,10,11,12,12.

So, the median = (8+10)/2 = 9.

The y-intercept is (0, 1).

Substituting [tex]x=-3[/tex] yields [tex]f(x)=-\frac{1}{3}(-3)+1=2[/tex].

So, draw the line through (0, 1) and (-3, 2).

Using it's concept, the probabilities for this problem are given as follows:

a) A occurs and B does not: 0.1817 = 18.17%.

b) Either occurs: 0.3434 = 34.34%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

In the context of this problem, we have two mutually exclusive events, meaning that they cannot happen together.

For item a, we have that:

The events are mutually exclusive, hence we can multiply the probabilities as follows:

p = 0.23 x 0.79 = 0.1817 = 18.17%.

For item b, we add the probability in item with the probability of B occurring and A not, found as follows:

Hence:

p = 0.1817 + 0.21 x 0.77 = 0.3434 = 34.34%.

The equation of the first line is y = -1/3x - 4, while the equivalent equations of the second line are y = -2/3(x - 3)  and y = -2/3x + 2

The given parameters are

Slope, m = 5/4

Point, (x1, y1) = (1, 3)

A linear equation is represented as

y = m(x - x1) + y1

So, we have

y = 5/4(x - 1) + 3

This gives

y = 5/4x + 7/4

Hence. the linear equation is y = 5/4x + 7/4

Here, we have

(x, y) = (3, 0) and (0, 2)

A linear equation is represented as

y = m(x - x1) + y1

Where

m = (y2 - y1)/(x2 - x1)

So, we have

m = (2 - 0)/(0 - 3)

m = -2/3

So, we have

y = -2/3(x - 3)

The above equation can be rewritten as

y = -2/3x + 2

Hence, the equations are y = -2/3(x - 3)  and y = -2/3x + 2
