By applying the concept of the pyramid, it can be concluded that the height of the larger pyramid is 5 m.
Pyramid is a 3-D shape that has a polygonal base and flat triangular faces, which join at a common point (the apex).
To find the volume of a pyramid, we multiply the area of its base by the height of the pyramid and divide by 3.
We have two similar pyramids. Let Va be the volume of the larger pyramid and Vb be the volume of the smaller pyramid:
Va = 123 m³
Vb = 27 m³
Let Ha be the height of the larger pyramid and Hb be the height of the smaller pyramid:
Hb = 3 m
Since these are similar pyramids, then their volume is proportional to their height.
For smaller pyramid:
Vb = 27 m³
= 3³ = Hb³
So we can determine Ha as follows:
Ha = ∛Va
= ∛125
= 5 m
Thus, the height of the larger pyramid is 5 m.

scatterplot is the best visualization for showing which of the following (choose one or more)? group of answer choices indirect or negative relationship between two ratio variables the relationship between two interval/ratio variables correlation frequency of two nominal variables
Scatterplots are best for showing the relationship between two interval/ratio variables and indirect or negative relationship between two ratio variables.
Scatterplots are best for showing:
⇒the relationship between two interval/ratio variables
⇒indirect or negative relationship between two ratio variables
Scatterplots display points on a coordinate plane, with one variable plotted on the x-axis and the other variable plotted on the y-axis. This allows us to see the pattern of relationship between the two variables. If there is a positive or negative relationship, we can see if the points tend to increase or decrease as we move from left to right or from bottom to top. If the relationship is indirect, we can see if the points tend to curve in one direction or another.
Scatterplots are not the best visualisation for showing: correlation
frequency of two nominal variables
For showing correlation, a line of best fit (regression line) can be added to a scatterplot, but other visualizations such as a correlation matrix or a heat map are more commonly used.
For showing frequency of two nominal variables, a two-way table or a mosaic plot are better suited, as they can display the count or proportion of cases for each combination of the two nominal variables.
Therefore, Scatterplots are best for showing the relationship between two interval/ratio variables and indirect or negative relationship between two ratio variables.

Able, Baker, and Charlie are the only three stocks in an index. The stocks sell for $37, $312, and $94, respectively. If Able undergoes a 3-for-4 reverse stock split, what is the new divisor?
In order to calculate the new divisor for a 3-for-4 reverse stock split, we must first calculate the new share price for Able. Since 3/4 of the shares are being replaced with just 1/4 of the old shares, the new price for Able will be $111 (3 x $37 = $111).
The divisor is used to calculate the new index value by dividing the sum of the new share prices by the divisor. Therefore, the new divisor will be 1.33 ($111 + $312 + $94 = $517 / 1.33 = $389.28). This is because the new share prices will total $517 and when you divide that by the divisor, the index value will be $389.28.

Why are there 52 weeks in a year and not 48 weeks given that there are only 4 weeks per month (4 x 12 = 48)?
A month does not have four weeks, nor does a year have 52 weeks.
The ISO week-numbering year, however, has 52 or 53 weeks.
That translates to 364 or 371 days rather than the typical 365 or 366 days.
Are there 4 weeks in every month?Since every month has at least 28 days, every month has 4 full weeks.
There are extra days in some months.
1 week = 7 days.

the equation for line r can be written as y= 1 2 x 8. line s, which is perpendicular to line r, includes the point (2, – 7). what is the equation of line s?
If the line "r" written as y = 1/2x + 8. is perpendicular to Line "s" which includes the point (2,-7) , then the equation of line"s" is y = -2x -3 .
The Equation of Line perpendicular to another line can be found by interchanging the x and y variables and negating the slope sign .
The equation of line r is : y = 1/2x + 8, and the slope of line r is 1/2.
The slope of a line perpendicular to line r will be the negative reciprocal of 1/2 that is -2.
So the equation of line s, which is perpendicular to line r and passes through the point (2, -7), can be written as follows:
⇒ y -(-7) = -2(x - 2)

The playground is surrounded by a fence that is 47. 1
feet long. About how much area will the playground
cover? Use 3. 14 for r. Round to the nearest tenth.
Help pls!
Rounding to the nearest tenth, the area of the playground is 176.7 square feet.
As per the data given in the question,
We have,
The shape of the playground = circular
So, for finding the area of a circle, we can use the formula of finding the area of a circle:
So, the value of the area will be: A = πr^2,
where A is the area and r is the radius.
Since the fence is 47.1 feet long,
we can assume that it is the circumference of the circle and divide it by 2π to find the radius:
47.1 feet / 2π
= 47.1 / (2 * 3.14)
= 7.5 feet
So the radius is 7.5 feet and the area of the playground is:

Part B: Use complete sentences to describe the angle relationship between the following angle pairs:
<4 and <1
<7 and <5
<9 and <10.
PLEASE HELP
Answer:
Step-by-step explanation:
Part A:
To find the value of the remaining angles, we can use the fact that the sum of the angles in a triangle is 180°.
First, let's find the value of <1. We have:
<4 + <1 + <2 = 180°
4 + <1 + (180° - 5 - 4) = 180°
4 + <1 + 171° = 180°
<1 = 5°
Next, let's find the value of <7. We have:
<7 + <5 + <6 = 180°
<7 + 135° + (180° - 10 - 5) = 180°
<7 + 135° + 165° = 180°
<7 = 0°
Finally, let's find the value of <9. We have:
<9 + <10 + <11 = 180°
<9 + 11° + (180° - 10 - 11) = 180°
<9 + 11° + 159° = 180°
<9 = 0°
Part B:
The angle <4 is supplementary to angle <1, meaning they add up to 180°.
The angle <7 is congruent to angle <5, meaning they have the same measure.
The angle <9 is congruent to angle <10, meaning they have the same measure.

What is a scale factor?
A scale factor is a number used to multiply the dimensions of a shape to enlarge or reduce its size. In geometry, the scale factor is used to create similar figures by preserving their shape while changing their size. If a figure is scaled up by a scale factor of 'k', its dimensions are increased by a factor of 'k'. If a figure is scaled down, its dimensions are reduced by a factor of 'k'.
For the triangle, the scale factor would be 3 units.
For the square, the scale factor would be 4 units.

According to the concept of fraction the value of the quantity at any time t is -4.
A fraction is a mathematical representation of division of two numbers. In this case, we will be using fractions to solve an initial value problem.
The initial value problem is ′=−2,(0)=−4.
This means that the rate of change of the quantity is -2 and its starting value at time 0 is -4.
To solve this problem, we need to find the value of the quantity at some other time.
Here the first step is to find the general solution to the differential equation ′=−2.
This can be done by integrating both sides, which gives us
=> −2.
Integrating, we get
=> −2 + C, where C is an arbitrary constant.
Next, we use the initial value to find the value of C.
We know that when t=0, the value of the quantity is -4, so we can substitute these values into the general solution to get
=> -4 = -2 + C.
Solving for C, we get C = -2.
Finally, we substitute C into the general solution to get

Use the first and last data points to find the slop intercept equation of the trend line.
The slope-intercept equation of the line that best fits the data, with a slope of 5.3333 and a y-intercept of 9.6666.
What is the slope?
The slope of a line represents the change in the dependent variable (y) for a unit change in the independent variable (x). In this case, the slope of the line of best fit represents the average change in the test grade for a one hour increase in studying. To find the slope, you can use the formula:
m = (Σxy - (Σx)(Σy)/n) / (Σx² - (Σx)²/n)
To find the slope-intercept equation of the trend line using the first and last data points, we'll first find the slope (m) of the line. The slope can be found using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where x₁ and y₁ are the values for the first data point, and x₂ and y₂ are the values for the last data point. In this case, the first data point is (1, 15) and the last data point is (7, 47):
m = (47 - 15) / (7 - 1) = 32 / 6 = 5.3333
Next, we'll use the slope and the first data point to find the y-intercept (b) using the formula:
b = y₁ - m * x₁
b = 15 - 5.3333 * 1 = 15 - 5.3333 = 9.6666
Finally, we'll use the slope and y-intercept to write the slope-intercept equation of the line:
y = mx + b

At the beginning of spring, Shaniece planted a small sunflower in her
backyard. When it was first planted, the sunflower was 25 inches tall. The
sunflower then began to grow at a rate of 0.5 inches per week. How tall would
the sunflower be after 10 weeks? How tall would the sunflower be after w
weeks?
Please help fast!!!!
The sunflower be after w weeks would be 25 + 0.5 * w inches tall.
What do you mean by algebraic expression?Let's say James and Natalie were playing with matchsticks when they had the idea to create number patterns with them. James made the number 4 with four matchsticks. In order to create a pattern with two 4s, Natalie added three extra matchsticks. They understood that they could keep adding three matchsticks each round to make an additional "four" by doing so. They deduced from this that, generally speaking, in order to create a pattern with n number of 4s, you need 4+ 3(n-1) sticks. We refer to 4+ 3(n-1) as an algebraic expression in this case.
To calculate the height of the sunflower after 10 weeks, we can use the formula:
height = starting height + growth rate * time elapsed
where the starting height is 25 inches, the growth rate is 0.5 inches per week, and the time elapsed is 10 weeks.
So the height after 10 weeks would be:
height = 25 + 0.5 * 10 = 25 + 5 = 30 inches
Therefore, the sunflower would be 30 inches tall after 10 weeks.
To calculate the height after w weeks, we can use the same formula:
height = 25 + 0.5 * w
So the height after w weeks would be:
height = 25 + 0.5 * w inches
This gives you the height of the sunflower in inches after w weeks of growth.

Which equation represents a tangent function with a domain of all real numbers such that x is not equal to pi over 2 plus pi times n comma where n is an integer?.
y = tan(x) - (π/2 + πn)
This equation represents a tangent function with a domain of all real numbers, except for multiples of pi/2 plus pi.
The equation y = tan(x) - (π/2 + πn) represents a tangent function with a domain of all real numbers except for multiples of pi/2 plus pi. This equation is useful for finding the tangent value of any given x-value, as long as it is not equal to a multiple of pi/2 plus pi. The equation works by subtracting the multiple of pi/2 plus pi from the x-value, and then finding the tangent of the new value. This allows the tangent of the x-value to be found, regardless of whether or not it is equal to a multiple of pi/2 plus pi.

a. The region D in the x-y plane is the area bounded by the two parabolas y= 2x2 and y= 1 x2. This can be seen in the sketch below.
b. To evaluate the integral ∫∫ df(x,y)dxdy, we need to evaluate the integral of the function f(x,y) = x2y over the region D. We can do this by setting up the integral as follows:
∫∫ df(x,y)dxdy = ∫-2 to 2 ∫2x2 to 1x2 x2(y)dxdy
Next, we can evaluate the integral by substituting the limits of integration for x and y and integrating with respect to x first. We get:
∫∫ df(x,y)dxdy = ∫-2 to 2 x2(1x2-2x2)dx = ∫-2 to 2 x2(-x2)dx = ∫-2 to 2 -x4dx = [-x5/5]from -2 to 2 = -2^5/5 + 2^5/5 = 0
