In this question, the length of the chord LN will be 15 inches long. It will be equal to PM.

Given,

At the circle's Centre, the Arc PL subtends an angle of 10 degrees.

At the circle's Centre, the Arc LM subtends an angle of 14 degrees.

At the circle's Centre, the Arc LN subtends a 24 degree angle.

The PM chord measures 15 inches in length.

What are the circle's chord theorems?

Considering the attached figure now,

The angle that the Arc PM creates at the Centre is equal to the sum of the angles that the Arc PL and Arc LM make there.

So,

At the middle, Arc PM will create the following angle: 10+14=24 degree.

We are aware that if the chords that make up the arc are equal, then the angle that it subtends in the Centre of the circle will likewise be equal.

Since, PM= 15 inches, therefore LN will also be 15 inches.

LN is therefore 15 inches as well.

Measurements are important for a safe and secure structure, as they must adhere to local building codes and regulations. Preliminary planning can be used to estimate the height, width, and length of the ramp and the amount of concrete and other materials needed.

A measurement is a measurable quantity that includes length, breadth, height, area, volume, weight, or time. Measurements are used to measure an object's or area's size, shape, or qualities.

A) Estimating measurements for a construction project such as this is not advisable, as accuracy is essential for ensuring the wall is stable and safe for use. Calculations must be precise in order to ensure the dimensions, material strength, and angles are correct, which is why it is important to use exact measurements in the plans.

B) In some cases, estimates may be acceptable. For example, the approximate number of blocks or pieces of material needed may be estimated based on the overall size and shape of the wall. Additionally, estimates of the time needed to complete the project may be made based on the experience of the construction team and the complexity of the project.

Using percentages, we can deduce that 160 of the 800 attendees at the football and math conference were teenagers or 20% of the total.

In mathematics, a value or ratio that can be expressed as a fraction of 100 is known as a percentage.

When determining a percentage of a number, we should first divide it by 100 before multiplying the result by 100.

Therefore, the proportion refers to a component per 100.

The word percent denotes a percentage of 100.

A percentage (%) is a number that represents how many out of 100 it is and can also be written as a decimal or fraction.

To convert a percentage to a fraction, place the percentage's value in the numerator and 100 in the denominator.

So, we are aware of:

The football game attracted 800 spectators.

20% of the population were teenagers.

The number of teens at that time was:

= 800/100*20

Answer:

one of the zeros is x = 0 and not x = 1

Step-by-step explanation:

Zeros are found by setting each of the factors to 0 and solving for x

Factors are x, x -4, x + 2

Set each of them to 0:
x =0
x + 2 = 0 ==> x = -2
x -4 = 0 ==> x = 4

So one of the zeros is x = 0 and not x = 1

Answer:

  79

Step-by-step explanation:

You want the smallest of 6 consecutive odd integers that have a sum of 504.

The average of the integers will be the even integer between the middle two odd integers. The smallest odd integer is 5 less than this average.

The average is the sum divided by the number of integers:

  504/6 = 84

The smallest of the 6 integers is 84 -5 = 79.

__

Additional comment

The integers are 79, 81, 83, 85, 87, 89.

Consecutive integer problems are often easily worked by considering the average of the integers, as here.

If you feel like you need an equation, you can let x represent the smallest. Then the sum is ...

  x +(x+2) +(x+4) +(x+6) +(x+8) +(x+10) = 6x +30 = 504

  6x = 474   ⇒   x = 474/6 = 79

The answer is  cov(x,y) = 0.059, if we choose a random point (X, Y ) uniformly from the union of the line segments AB and AC.

As given, A = (0, 0) ,B = (1, 0) and C = (0, 1)

and we have the select x and y from line segment AB and AC respectively.

So, x can be 1.0, 0.8, 0.6, 0.4, 0.2

and y  can be 1.0, 0.8, 0.6, 0.4, 0.2

Now we have to find,

                     cov(x,y) = ∑(Xi - μ) (Yj - v) / n

where,

Now µ = 1.0 + 0.8 + 0.6 + 0.4 + 0.2 + 0.0 ÷ 6

        µ = 3 ÷ 6

        µ = 1/2 = 0.5

Now v = 1.0 + 0.8 + 0.6 + 0.4 + 0.2 + 0.0 ÷ 6

        v = 3 ÷ 6

        v = 1/2 = 0.5

Now, we have to find

       (Xi - µ) = (1.0 - 0.5), (0. 8- 0.5), (0.6 - 0.5), (0.4 - 0.5), (0.2 - 0.5),                            

                           (0.0 - 0.5)

        (Xi - µ) = 0.5, 0.3, 0.1, (-0.1), (-0.3), (-0.5)

(Yj - v) =  (1.0 - 0.5), (0. 8- 0.5), (0.6 - 0.5), (0.4 - 0.5), (0.2 - 0.5),                            

                           (0.0 - 0.5)

(Yj - v) = 0.5, 0.3, 0.1, (-0.1), (-0.3), (-0.5)

Now calculate (Xi - μ) (Yj - v): multiply them with their respective one

(Xi - μ) (Yj - v) = (0.5×0.5), (0.3×0.3), (0.1×o.1), (-0.1)(-0.1), (-0.3)(-0.3),

                         (-0.5)(0.5)

therefore,

∑(Xi - μ) (Yj - v) = (0.25+ 0.09 + 0.01 + 0.01 + 0.09 + 0.25)

∑(Xi - μ) (Yj - v) =0.35

Now,  cov(x,y) = ∑(Xi - μ) (Yj - v) / n

          cov(x,y) = 0.35 / 6

          cov(x,y) = 0.059

The expected number of 3's would be 5.

What is probability?

Probability is a field of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of inaccuracy in study by using probability.

The probability of rolling a 3 on a single roll of a fair six-sided die is 1/6, since there is one favorable outcome (rolling a 3) out of a total of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).

However, it's important to keep in mind that the actual number of 3's obtained in 30 rolls of a die can vary, as the outcome of each roll is inherently random.

The expected value provides us with a guide for what to expect on average, but in any given sequence of rolls, the actual number of 3's may be higher or lower.

So, if you roll the cube 30 times, the expected number of 3's would be 30 * 1/6 = 5.

To graph the instructions described we must perform the following procedure:

First of all we must carefully read the instructions and identify what the first step is. In this case we must draw a horizontal line 7 cm long.

Secondly, we must draw a line at the point equidistant from the points X and Z, that is, halfway between these two points. If we take into account that the first line measures 7 cm, this point will be 3.5 cm from each point.

Thirdly, we must give a length of 6 cm to this central line and it must also be equidistant. Therefore, we must give it 3 cm upwards and 3 cm downwards in length so that it is equidistant.
