Answer: 8 employees doing both jobs.
Step-by-step explanation:
If 4 do neither, we can subtract this from the total number of employees. This will give us the employees that work with customers, the warehouse, or both.
36 - 4 = 32 employees
Next, we need to find how many do both. We can add 29 and 11 together to find the total number of jobs worked in these sections (this will include employees doing both jobs).
29 + 11 = 40 employees
Lastly, we will subtract the total number of employees working in these sections from the number above to find how many are doing both jobs.
40 - 32 = 8 employees doing both jobs.

A 50 foot rope is stretched tight from the roof of a building to a spot 20 feet from the base of the
building. How tall is the building? Round your answer to TWO decimal places.
47.17 feet is the height of the building.
We can use the Pythagorean theorem to solve the problem:
Let h be the height of the building.
Then we have a right triangle with legs 20 and h, and a hypotenuse 50.
Using the Pythagorean theorem, we have:
[tex]50^2 = 20^2 + h^2[/tex]
Simplifying and solving for h, we get:
[tex]h = \sqrt{(50^2 - 20^2)[/tex]
h ≈ 47.17 feet (rounded to two decimal places)
Therefore, the height of the building is approximately 47.17 feet.

The length of the arc KL in the given circle is 3.49 units
How to find the length of the arc KL?In a circle whose radius is R, the length of an arc defined by an angle x is given by:
Length = (x/360)*2*3.14*R
Here we know that the radius is 2 units, and the angle for the arc KL is 100°, then we can replace these values in the formula above so we get that the length of the arc is:
Length = (100/360)*2*3.14*2

A police radar gun is used to measure the speeds of cars on a highway. The speeds of cars are normally
distributed with a mean of 55 mi/hr and a standard deviation of 5 mi/hr. Roughly what percentage of cars
are driving less than 65 mi/hr? Use the empirical rule to solve the problem. (Round to the nearest tenth of a
percent)
The solution is : the percentage of cars that are driving less than 45 mi/hr is 2.3%
Here, we have,
Since the speeds of cars are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = speeds of cars
µ = mean speed
σ = standard deviation
From the information given,
µ = 55 mi/hr
σ = 5 mi/hr
The probability that a car is driving less than 45 mi/hr is expressed as
P(x < 45)
For x = 45
z = (45 - 55)/5 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
Therefore, the percentage of cars that are driving less than 45 mi/hr is
0.023 × 100 = 2.3%

Tres engranajes tangentes entre sí, cuyos radios miden 15, 16 y 17 cm, deben ser sostenidos por
una base triangular que tiene por vértices los centros de cada engranaje. Hallar los ángulos
interiores del triángulo y expresarlos según el sistema de medición radial.
Para resolver este problema, podemos utilizar el Teorema de los Cosenos para calcular los ángulos interiores del triángulo.
Sea A, B y C los vértices del triángulo correspondientes a los centros de los engranajes. Sea a, b y c las longitudes de los lados opuestos a los ángulos A, B y C respectivamente.
Dado que los radios de los engranajes miden 15 cm, 16 cm y 17 cm, podemos considerar que los lados del triángulo son a = 15 cm, b = 16 cm y c = 17 cm.
El Teorema de los Cosenos establece que en un triángulo con lados a, b y c, y ángulos opuestos A, B y C respectivamente, se cumple la siguiente fórmula:
c^2 = a^2 + b^2 - 2ab * cos(C)
Podemos aplicar esta fórmula para cada uno de los ángulos del triángulo.
Para el ángulo A, tenemos:
c^2 = b^2 + a^2 - 2ab * cos(A)
17^2 = 16^2 + 15^2 - 2 * 16 * 15 * cos(A)
Resolviendo la ecuación, encontramos que cos(A) = -1/8. Tomando el coseno inverso (arcocoseno), encontramos que el ángulo A es aproximadamente 135.2 grados en el sistema de medición radial.
Para el ángulo B, tenemos:
a^2 = c^2 + b^2 - 2cb * cos(B)
15^2 = 17^2 + 16^2 - 2 * 17 * 16 * cos(B)
Resolviendo la ecuación, encontramos que cos(B) = -7/17. Tomando el coseno inverso, encontramos que el ángulo B es aproximadamente 120.6 grados en el sistema de medición radial.
Para el ángulo C, tenemos:
b^2 = a^2 + c^2 - 2ac * cos(C)
16^2 = 15^2 + 17^2 - 2 * 15 * 17 * cos(C)
Resolviendo la ecuación, encontramos que cos(C) = -1/2. Tomando el coseno inverso, encontramos que el ángulo C es aproximadamente 120 grados en el sistema de medición radial.
Entonces, los ángulos interiores del triángulo son:
A ≈ 135.2 grados
B ≈ 120.6 grados
C ≈ 120 grados
Estos valores están expresados en el sistema de medición radial.

Solve. |7x-20|=|2x+20|
To solve the equation |7x - 20| = |2x + 20|, we need to consider two cases based on the absolute values.
Case 1: (7x - 20) = (2x + 20)
Simplifying this equation, we get:
7x - 20 = 2x + 20
Subtracting 2x from both sides:
5x - 20 = 20
Adding 20 to both sides:
5x = 40
Dividing both sides by 5:
x = 8
Case 2: (7x - 20) = -(2x + 20)
Simplifying this equation, we get:
7x - 20 = -2x - 20
Adding 2x to both sides:
9x - 20 = -20
Adding 20 to both sides:
9x = 0
Dividing both sides by 9:
x = 0
Therefore, the solutions to the equation |7x - 20| = |2x + 20| are x = 8 and x = 0.
(x+3)(x+7)=0

3.28
4.16
The measure of angle ACB is half the difference between 180 degrees and the measure of arc AB.
The measure of angle ACB can be determined using the properties of tangents and secants intersecting a circle.
Since side AC is tangent to the circle, angle BAC is a right angle (90 degrees).
According to the tangent-secant theorem, the measure of angle ACB is equal to half the difference between the intercepted arcs AB and AX.
Since angle BAC is a right angle, the intercepted arc AX is a semicircle, which means its measure is 180 degrees. The intercepted arc AB is an arc of the circle and is less than 180 degrees since it is not a full circle.
Therefore, the measure of angle ACB is half the difference between 180 degrees and the measure of arc AB.
To find the exact measure, more information is needed about the length of arc AB or the relationship between the lengths of the sides of the triangle. Without this additional information, we cannot determine the precise measure of angle ACB.

If the equation is an identity
The equation is an identity is discussed below.
An identity is a mathematical equation that holds true for all values of the variables involved.
In other words, it is true regardless of the specific values of the variables. When an equation is an identity, it means that both sides of the equation are equivalent and represent the same mathematical relationship.
For example, the equation 2x + 3 = 2(x + 1) is an identity because it holds true for all values of x.
When an equation is an identity, it provides a general statement or rule that is universally applicable and does not depend on specific values or conditions. Identifying an equation as an identity is important because it allows us to make general conclusions and deductions that apply in all cases.

a) What are the mean and standard deviation of the number of workers with a college degree respectively?
b) What is the probability that the number of workers with a college degree is at least 35?
The mean number of workers with a college degree is 40.8, and the standard deviation is 5.37.
The probability that the number of workers with a college degree is at least 35 is 0.976, or 97.6%.
Given Sample size (n) is 120 workers
Proportion of workers who are college graduates (p): 34% or 0.34
a) Mean and Standard Deviation:
The mean (μ) of a binomial distribution is given by μ = np, and the standard deviation (σ) is given by σ =√np(1 - p).
Substituting the values:
μ = 120 ×0.34 = 40.8
σ = √120 × 0.34 × (1 - 0.34)) = 5.37
To find the probability that the number of workers with a college degree is at least 35
we need to calculate the cumulative probability of the binomial distribution from 35 to the maximum possible value, which is 120 in this case.
Using a binomial probability calculator or a statistical software, we can find this probability.
Assuming a binomial distribution with parameters n = 120 and p = 0.34, the probability can be calculated as follows:
P(X ≥ 35) = 1 - P(X < 35)

To write this in standard form, we first convert the number to a decimal between 1 and 10 by moving the decimal point three places to the left. This gives us a decimal of 0.001. The exponent is already in the form of a power of 10, so we can leave it as [tex]10^-^3[/tex]. Thus, the weight of a pitaya seed in standard form is:
[tex]0.001 \times 10^-^3[/tex]
To simplify this expression, we can multiply the decimal and the exponent. This gives us:
