Step-by-step explanation:

Since the lines cross over each other, yes, they do bisect each other.

Using triangle proportionality AB/AD is proportional to BC/CD. Using the isosceles triangle in the construction EC = EB.

These lead to the proportion that corresponds to the angle bisector theorem of AB/AD = AC/CD.

The angle bisector theorem states that the angle bisector of a triangle divides the opposite side into segments that are proportional to the other two sides of the triangle. This theorem can be proven using triangle similarity and the concept of proportionality.

Let ABC be a triangle with angle bisector AD, where D lies on BC. To show that AB/BD = AC/CD.

First, use the fact that triangles ABD and ACD are similar by angle-angle-angle similarity, since they share two congruent angles (angle A and angle BAD is congruent to angle CAD by the angle bisector theorem). Therefore:

AB/AD = BD/CD (by the definition of similar triangles)

Cross-multiplying gives:

AB × CD = AD × BD

Similarly, use the fact that triangles ABC and ABD are similar:

AB/AC = BD/CD

Cross-multiplying gives:

AB × CD = AC × BD

Combining these two equations:

AB × CD = AD × BD = AC × BD

Dividing both sides by BD gives:

AB/BD = AC/CD

Therefore, the angle bisector theorem is proven.

The two options that could result from combining two linear functions with addition are "16x – 12" and "17x – 12". The r to your question is:

To combine two linear functions with addition, you simply add the coefficients of the same variables. For example, if you have the functions 3x + 4 and 2x - 5, when you combine them with addition, you add the coefficients of x and the constant terms. So, 3x + 4 + 2x - 5 becomes (3 + 2)x + (4 - 5) = 5x - 1.

To combine two linear functions with multiplication, you multiply the coefficients of the same variables. For example, if you have the functions 3x + 4 and 2x - 5, when you combine them with multiplication, you multiply the coefficients of x and the constant terms. So, (3x + 4)(2x - 5) becomes

(3 * 2)x^2 + (3 * -5)x + (4 * 2x) + (4 * -5)

= 6x^2 - 15x + 8x - 20

= 6x^2 - 7x - 20.

If a firm offers rutine physical examinations as a part of a health service program for its employees. The probability that an employee selected at random will need either corrective shoes or major dental work is 60%.

Let the probability of needing corrective shoes be P(CS) and the probability of needing major dental work be P(MDW).

P(CS) = 28% = 0.28

P(MDW) = 35% = 0.35

Now let calculate the probability of needing either corrective shoes or major dental work

P(CS or MDW) = P(CS) + P(MDW) - P(CS and MDW)

P(CS or MDW) = 0.28 + 0.35 - 0.03

P(CS or MDW) = 0.60

The value of x is 48⁰ if EF is tangent to the circle at E.

In geometry, a tangent to a circle is a straight line or line segment that touches the circle at exactly one point. This point of contact is called the point of tangency.

To find the center angle we need to join OD and OC as shown in Figure.

∠ODC = ∠OCD = 90⁰ - 70⁰ = 20⁰

∠DOC = 180⁰ - 20⁰ - 20⁰ = 140⁰

Hence,

(5x-20)⁰ = 360⁰ - 140⁰

5x - 20 = 220⁰

5x = 240⁰

x = 48⁰

Hence, the value of x is 48⁰

The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

This time is determined by the projectile's starting velocity as well as the angle of projection. When the projectile reaches a vertical velocity equal zero magnitudes, it has reached its maximum height. Furthermore, gravity would take over and accelerate the thing downward.

Given that,

y = -2sin\((\frac{2\pi (t+1)}{7})\) + 5

For maximum height,

sin(2π(t + 1))/7) = -1

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = 3π/2

t + 1 = 21/4

t = 4.25 seconds

To determine if it would be unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name, we can use the concept of standard deviation and z-scores.

First, we need to calculate the z-score, which measures how many standard deviations an observation is from the mean. The formula for calculating the z-score is:

z = (x - μ) / σ

where

z = (5 - 9.3) / 0.99

z = -4.394

Next, we can consult a standard normal distribution table or use statistical software to find the corresponding percentile associated with the z-score. This percentile represents the probability of randomly selecting a group of 12 people with fewer than 5 recognizing the Yummy brand name.

In this case, the z-score of -4.394 corresponds to an extremely low percentile, close to 0.

The exact probability can be determined using the z-score and the standard normal distribution table.

Since the probability is extremely low, it would be considered unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name.

However, it's important to note that the definition of "unusual" may vary depending on the specific criteria or threshold chosen.

In statistical terms, a common threshold for defining unusual events is a significance level of 5% (or 0.05). If the probability of observing the event is lower than the significance level, it is considered unusual.

The PDF describes the rate at which probability is accumulating around a given point, while the CDF gives the probability that the random variable takes on a value less than or equal to a given value.

The probability density function (PDF) and cumulative distribution function (CDF) are two different ways of representing the same information about a probability distribution.

The PDF gives the probability density of a continuous random variable at a particular point in its domain. In other words, the PDF gives the rate at which the probability is accumulating around a given point. The area under the PDF curve between two points represents the probability of the random variable taking on a value between those two points.

On the other hand, the CDF gives the probability that a random variable is less than or equal to a given value. The CDF is the integral of the PDF from negative infinity up to that value.

Therefore, the CDF and PDF are related by integration: The CDF is the integral of the PDF, and the PDF is the derivative of the CDF.

The national average for energy usage per home in BTU is approximately 90 BTU.

BTU stands for British Thermal Unit, which is the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. It is used to quantify the amount of energy consumed by heating or cooling equipment.In California, people use 63 BTU of energy per home, which is 30% less than the national average. Therefore, to calculate the average BTU consumption for American households, we will use the following formula: National average BTU = California BTU / (1 - 30%)

Let's solve for the national average BTU: National average BTU = 63 BTU / (1 - 0.30)

National average BTU = 63 BTU / 0.70National average BTU = 90 BTU

Therefore, the average American household uses 90 BTU of energy per home.

There are 12 people who can be president.

For each of those choices, there are 11 VP candidates. That’s 11 twelve times, or 132.

For each of those132 possibilities, there are 10 Secretary options, so 1320.

Now there are 9 people remaining who might be selected as Treasurer. That’s 11,880 combinations.

It’s this high because, while no one can be in two positions, all the possible arrangements of each four need to be counted.

For example, if Angela, Bradley, Cara, and Davide are the four chosen, they can be in any of these arrangements:-

ABCD | BACD | CABD | DABC

ABDC | BADC | CADB | DACB

ACBD | BCAD | CBAD | DBAC

ACDB | BCDA | CBDA | DBCA

ADBC | BDAC | CDAB | DCAB

ADCB | BDCA | CDBA | DCBA

This is 24 times the normal condition for this sort of problem, where those 4 are interchangeable. In that case, often framed as a roll of some number of dice, there would be only “12 choose 4” combinations, for a total of 495.
