Step-by-step explanation:
Given the scale is 1 centimeter represents 3 meters, to scale the dimensions of the drawing to the dimensions of the actual room, multiply the dimensions of the drawing by 3.
Therefore:
3 cm × 3 = 9 m2 cm × 3 = 6 mSo the dimensions of the actual room are:
Length = 9 mWidth = 6 mThe area of a rectangle is the product of its width and length.
Therefore, the area of the actual room is:

b. If you sampled 2000 people, how many would you expect to have BP> 160? Give your answer to the nearest person. Note: I had a bit of an issue encoding rounded answers, so try rounding both up and down if there's an issue!
a) The percentage of adults in the USA that have stage 2 high blood pressure is; 0.27%
b) The number of people that you will expect to have BP greater than 160 is; 54
How to get p-value from z-score?a) if x is systolic blood pressure, then want to find probability that x ≥ 160.
The formula for z-score is;
z = (x - mean)/standard deviation
Thus;
z = (x - 119)/18
This is normally distributed with mean 0 and standard deviation 1
Transform x to z:
P(x > 160) = P(z > (160 - 119)/18)
= P(z > 2.78)
= P(z < -2.78)
= 0.0027 (from standard normal distribution table, which 0.27%.)
b) Since probability of BP > 160 is 0.027.
Then out of 2000 people, then 2000 * 0.027 = 54 people would have BP > 160.

To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):
x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)
Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:
x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7
Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.
Note that this expression is defined for all values of x and y except for x=0.

What is transformation?Transformation in maths is the process of changing the position, size, orientation or shape of a figure or shape. It involves various techniques such as translation, rotation, reflection and scaling.
The transformation (x, y)-- (x-3,y+1) followed by a dilation centered at the origin with scale factor 2 is a combination of a translation and a dilation. A translation is a transformation that moves the shape without changing its size or orientation. In this case, the translation moves the triangle 3 units to the left and 1 unit up. A dilation is a transformation that enlarges or reduces a shape. In this case, the dilation uses a scale factor of 2, so the triangle will be twice as big as it was before.
The vertices of the original triangle ABC are (A(x1,y1), B(x2,y2), C(x3,y3)). After the translation, the vertices will be (A(x1-3,y1+1), B(x2-3,y2+1), C(x3-3,y3+1)). After the dilation, the vertices will be (A(2(x1-3),2(y1+1)), B(2(x2-3),2(y2+1)), C(2(x3-3),2(y3+1)).

people
To predict the average number of people attending local baseball games in 2024, we need to use the formula:
A = P(1 + r)^n
where:
A = the predicted average attendance in 2024
P = the current average attendance (in 2020)
r = the annual growth rate (as a decimal)
n = the number of years of growth (from 2020 to 2024)
Given that the annual growth rate is 10% and the number of years of growth is 4 (from 2020 to 2024), we have:
r = 0.10
n = 4
Substituting these values and the current average attendance of 100 people into the formula, we get:
A = 100(1 + 0.10)^4
A = 100(1.10)^4
A = 100(1.4641)
A = 146.41
Therefore, the predicted average number of people attending local baseball games in 2024 is approximately 146 (rounded to the nearest whole number).

What is an area exactly?By calculating how much space would be needed to fully cover its exterior, its overall size can be calculated. The neighboring area is considered when selecting a comparable item for a rectangular design. The surface area of something determines its overall dimensions. The number of sides between a cuboid four trapezoidal curves determines how much water it can hold.
Here,
Let w represent the rectangle's breadth.
In light of the issue statement, the rectangle's length is 2w - 3.
Since the rectangle's area is 65, we can construct the following equation:
=> w(2w - 3) = 65
By enlarging and condensing the left half, we obtain:
=>2w² - 3w - 65 = 0
Now that we have the quadratic formula, we can answer this quadratic equation:
=> w = (-b √(b² - 4ac)) / 2a.
where c = -65, b = 3, and a = 2. By replacing these numbers, we obtain:
=> w = (-(-3) ± √(-3)² - 4(2)(-65))) / 2(2)
=> w = (3 + √(529)) / 4
=> w = (3 ± 23) / 4
=> w = (3 + 23) / 4 = 6.5
=> l = 2w - 3 = 2(6.5) - 3 = 10
The rectangle's dimensions are 6.5 yards and 10 yards, respectively.

Based on Probability laws the answers are: (a) n(1-p) = 167.4 and (b) mean = 167.4
(a) To demonstrate that the probability distribution of X is roughly normal, we must determine if np and n(1-p), where n is the sample size and p is the chance of success, are both higher than or equal to 10. (using a variation of "lol").
If 55.8% of comments containing a textual form of laughter use some version of "lol," the numbers in this case are n = 300 and p = 0.558. Therefore:
[tex]n(1-p) = 300 * 0.442 = 132.6 np = 300 * 0.558 = 167.4[/tex]

Answer:
RESOLUCIÓN.
Para resolver este problema hay que seguir los siguientes pasos:
1) Determinar la comisión del vendedor de seguros.
Se sabe por datos del problema que cuando vendió $3000 su sueldo total fue de $850 y cuando vendió $4000 su sueldo total fue de $1000, eso quiere decir que:
Venta = 4000 - 3000 = $1000
Sueldo = 1000 - 850 = $150
Es decir que por cada $1000 en ventas, su ganancia es de $150.
1000 ---> 100%
150 ---> x
x = 150 * 100 / 1000 = 15%
Por lo tanto el porcentaje de comisión del vendedor es de 15% por venta.
2) Determinar el salario semanal fijo del vendedor.
Una vez conocido el porcentaje de comisión se puede obtener el salario fijo.
Para el primer caso:
850 = Salario fijo + Comisión
Comisión = 3000 * 15/ 100 = $450
Por lo tanto se tiene que:
850 = Salario fijo + 450
Salario fijo = $400
Por lo tanto se tiene que el salario semanal del vendedor es de $400.

How to find BCThe problem gave that the two triangles are similar triangles and the proportions will be used to find the length of BC as below
5 / (x - 4) = (x + 7) / 12
cross multiplying
60 = (x - 4) (x + 7)
60 = x^2 + 3x - 28
x^2 + 3x - 88 = 0
x = 8 or -11
take the positive value hence x = 8
Solving for BD
side DE = x - 4 = 8 - 4 = 4
taking proportions we have
DE / FE = AB / BC
4 / 8 = 12 / BC
BC = 8 * 12 / 4 = 24

Suppose you invest $25,000 in a one-year certificate of deposit (CD) that pays simple interest at 4.25% annually. The CD is cashable at any time, with interest payable on a prorated basis. If you cashed the CD after seven months, how much would you earn in interest?
A $556.25
B $656.25
C $612.50
D $468.75
The amount of simple interest earned after 7 months is given as follows:
C $612.50
How to obtain the balance using simple interest?The equation that gives the balance of an account after t years, considering simple interest, is modeled as follows:
A(t) = P(1 + rt).
In which the parameters of the equation are listed and explained as follows:
A(t) is the final balance.P is the value of the initial deposit.r is the interest rate, as a decimal.t is the time in years.The interest accrued over the period is modeled as follows:
I(t) = Prt.
The parameter values for this problem are given as follows:
P = 25000.r = 0.0425.t = 7/12 -> as the time is measured in one year, hence 7 months = 7/12 of an year.Then the accumulated interest is given as follows:
I = 25000 x 0.0425 x 7/12
I = $612.50.

What is the principal square root? And why is it used when solving radical
polynomials?
Answer:
The principal square root of a non-negative real number is the positive square root. For example, the principal square root of 25 is 5, since 5^2 = 25.
When solving radical polynomials, the principal square root is used because it is the most commonly used square root. In many contexts, including mathematical and scientific calculations, the principal square root is the default choice unless otherwise specified. Additionally, when working with radical expressions, we often simplify expressions by taking the principal square root, as it can help us to simplify calculations and express answers more clearly.
A cone has a base area of 24 square inches and a height of 8 inches. What is the area of a cross-section of the cone that is parallel to the base and 3 inches from the vertex?
A circular cross section is marked near the vertex of a cone, parallel to the base.
The area of the cross-section of the cone that is parallel to the base and 3 inches from the vertex is square inches.
The area of the cross-section of the cone that is parallel to the base and 3 inches from the vertex is 27/8 square inches or 3 3/8 square inches
Calculating the area of the cross section of a coneFrom the question, we are to determine the area of the cross-section of the cone
To determine the area of the cross-section of the cone, we will determine the radius of the cross-section.
Let the radius of the cross-section be x and radius of the base of the be r.
The height of the cone is 8 inches and the height of the cone formed from the cross-section is 3 inches
By similar triangle theorem, we can write that
8/r = 3/x
x = (3r)/8
From the given information,
The area of the base is 24 square inches
Thus,
πr² = 24
Therefore, r² = 24/π
The area of the cross-section will be
A = πx²
But, x = (3r)/8
Thus,
A = π [(3r)/8]²
A = π × 3²/8² × r²
A = π × 9/64 × 24/π
A = 27/8 square inches
Hence, the area is 27/8 square inches or 3 3/8 square inches
