An osteoblast is referred to as an osteocyte when it is entirely encircled by the secretions of its own matrix.

Osteocyte is a specific kind of bone cell that develops when the osteblast, which produces the bone's structural material, is surrounded by material that it has released on its own. Osteocytes, which make up 90–95% of the cells in bone tissue as opposed to osteoclasts and osteoblasts, which make up just 5%, are the longest-living bone cells. (40). Osteoblasts develop into osteoocytes when they are implanted in the mineral matrix of bone and acquire unique properties.

Osteocytes function as endocrine cells, emitting hormones to regulate local deposit of minerals and chemistry at the cellular level of the bone matrix as well as phosphate transport to other organs like the kidney. Osteocytes appear to be principally responsible for many bone activities.

Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are  parallel, making two angles congruent and the triangles therefore similar.

Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height

Maria works 24.5 hours a week and earns 8.76 per hour, thus she makes 214.02 each week.

To calculate how much Maria earns each week, we need to multiply the number of hours she works by her hourly rate of pay.

Maria works for 24.5 hours each week, and she earns $8.76 per hour.

So, to calculate her earnings, we can use the formula:

Earnings = Hours worked x Hourly rate of pay

Substituting the values we have, we get:

Earnings = 24.5 hours x $8.76 per hour

Earnings = $214.02

Therefore, Maria earns $214.02 each week working at the bookstore. It is important to note that this is before taxes and other deductions that may be applicable, which would result in her net pay being lower than this amount.

To select the appropriate wide flange steel girder for a simple span of 9 meters, subjected to a concentrated load of 4667 kN at the midspan, we need to calculate the required section modulus and check if it is available for A36 steel.

Step 1: Calculate the required section modulus:
The section modulus (S) represents the resistance of a beam to bending. It can be calculated using the formula:

                                                          S = (P * L^2) / (4 * M)

where:
         P is the concentrated load at the midspan (4667 kN),
          L is the span length (9 m),
          M is the moment at the midspan (P * L / 4).

In this case, the moment at the midspan is (4667 kN * 9 m) / 4

                                                                         = 10476.75 kNm.
Substituting the values into the formula, we get:
                                 S = (4667 kN * (9 m)^2) / (4 * 10476.75 kNm)
                                S ≈ 37.9684 * 10^3 mm^3

Step 2: Check the availability of the section modulus for A36 steel:
To select the appropriate steel girder, we need to compare the calculated section modulus (S) with the available section moduli for A36 steel.

A 2x3x2 factorial design has three independent variables. What is a factorial design? A factorial design is an experimental design that studies the impact of two or more independent variables on a dependent variable.

The notation of a factorial design specifies how many independent variables are used and how many levels each independent variable has. In a 2x3x2 factorial design, there are three independent variables, with the first variable having two levels, the second variable having three levels, and the third variable having two levels.

The number of treatments or conditions required to create all feasible combinations of the independent variables is equal to the total number of cells in the design matrix, which can be computed as the product of the levels for each factor.

In this case, the number of cells would be 2x3x2=12.Therefore, a 2x3x2 factorial design has three independent variables and 12 treatment groups..

Answer:

The second statement is correct

Step-by-step explanation:

Hello!

The table shows the information of the favorite film genre of the students of the class regarding their gender.

You have to prove which statement is correct:

1)The probability of randomly selecting a student who has a favorite genre of drama and is also female is about 17 percent.

If you chose a student at random, you need to calculate the probability of its favorite genre being "Drama" (D) and the student being female (F), symbolically: P(D∩F)

To do so you have to divide the number of observed students that are female and like drama by the total number of students:

P(D∩F)= \(\frac{24}{240}= \frac{1}{10} =0.10\)

This means that the probability of choosing a student at random and it being a female that likes drama is 10%.

This statement is incorrect.

2) Event F for female and event D for drama are independent events.

Two events are independent when the occurrence of one of them doesn't affect the probability of occurrence of the other one.

So if F and D are independent then:

P(F)= P(F|D)

-or-

P(D)=P(D|F)

The probability of the event "Female" is equal to \(P(F)= \frac{Total females in the class}{n} = \frac{144}{240} = \frac{3}{5}= 0.6\)

The probability of the event "Drama" is:

\(P(D)= \frac{Total students that like "Drama"}{n}= \frac{40}{240}= \frac{1}{6}= 0.166\)

\(P(F|D)= \frac{P(FnD)}{P(D)}= \frac{\frac{1}{10} }{\frac{1}{6} }= \frac{3}{5} = 0.6\)

As you can see P(F)= 0.6 and P(F|D)= 0.6 so both events are independent.

This statement is correct.

3) The probability of randomly selecting a male student, given that his favorite genre is horror, is  16/40

This is a conditional probability, you already know that the student likes horror movies (H), and out of that group you want to know the probability of the student being male (M):

\(P(M|H)= \frac{number of male students that like horror movies}{total students that like horror movies}= \frac{16}{38}= \frac{8}{19} = 0.42\)

This statement is incorrect.

4) Event M for male and event A for action are independent events.

Same as the second statement, if the events "Male" and "Action" are independent then:

P(M)= P(M|A)

-or-

P(A)= P(A|M)

\(P(M)= \frac{96}{240}= \frac{2}{5}= 0.4\)

\(P(A)= \frac{72}{240} =\frac{3}{10}= 0.3\)

\(P(AnM)= \frac{28}{240}= \frac{7}{60}= 0.11666\)

\(P(M|A)= \frac{P(MnA)}{P(A)}= \frac{\frac{7}{60} }{\frac{3}{10} } = \frac{7}{18}= 0.3888\)

\(P(M)= \frac{2}{5}\) and \(P(M|A)= \frac{7}{18}\)

P(M)≠ P(M|A) the events are not independent.

This statement is incorrect.

The body masses of the two children in terms of their father's body mass, x, are:

First child's body mass = 5x/6 kg

Second child's body mass = 4x/5 kg

To express the body mass of the man's two children in terms of their father's body mass, we can use the given ratios.

Let the body mass of the man be x kg.

The first child's body mass is five-sixths of their father's body mass:

Body mass of the first child = (5/6) * x

= 5x/6 kg.

The second child's body mass is four-fifths of their father's body mass:

Body mass of the second child = (4/5) * x

= 4x/5 kg.

Step-by-step explanation:

If angle 5 is 134˚, then that means angle 2 must be 46.

Inside the triangle, we have three angles. A right angle of 90˚, angle 2 of 46˚ and the unknown angle 1. Since the total sum of the angles in a triangle must be 180, we can solve for angle 1:

180 = 90 + 46 + x

Therefore:

x = 43˚

Angle 1 is 43 degrees.

The three integration techniques are outlined below for each of the given integrals, as well as the specified value of n. They all round their answers to six decimal places.

The trapezoidal rule, the midpoint rule, and Simpson's rule are all numerical integration techniques used to approximate a given integral. The three integration techniques are outlined below for each of the given integrals, as well as the specified value of n. They all round their answers to six decimal places.The trapezoidal rule is a technique used to calculate an approximation of a definite integral using trapezoids. The integral is split into a number of small regions, and each of these regions is used to create a trapezoid. The area of each trapezoid is then calculated, and these areas are added together to get an approximation of the integral. The formula for the trapezoidal rule is given by: ∫ba f(x)dx ≈ [f(a) + f(b)]/2 + ∑f(xi)Δx.

(a) Trapezoidal rule: n = 5∫3 6 t in(x)dx= [f(a) + f(b)]/2 + ∑f(xi)Δx(f(3) + f(6))/2 + [f(3.6) + f(4.2) + f(4.8) + f(5.4) + f(6)](0.6) ≈ 5.820265

The midpoint rule is a numerical integration technique that approximates a definite integral using rectangles. The midpoint rule divides the integration interval into a number of sub-intervals of equal length, and then approximates the integral using the midpoints of each sub-interval. The formula for the midpoint rule is given by: ∫ba f(x)dx ≈ ∑f(xi)Δx, where xi = a + (i - 1/2)Δx.

(b) Midpoint rule: n = 5∫3 6 tin(x)dx= ∑f(xi)Δx0.6[f(3.3) + f(3.9) + f(4.5) + f(5.1) + f(5.7)]≈ 5.870109

Simpson's rule is a numerical integration technique that approximates a definite integral using quadratic approximations of the integrand. The integral is divided into a number of sub-intervals, and the integrand is approximated using a quadratic function on each sub-interval. The formula for Simpson's rule is given by: ∫ba f(x)dx ≈ [f(a) + f(b)]/3 + ∑f(xi)Δx(f(a) + 4f(xi) + f(b))/3

(c) Simpson's rule: n = 5∫3 6 t in(x)dx= [f(a) + f(b)]/3 + ∑f(xi)Δx(f(3) + 4f(4.2) + 2f(4.8) + 4f(5.4) + f(6))/3(0.6) ≈ 5.820237

The trapezoidal rule, the midpoint rule, and Simpson's rule are all numerical integration techniques used to approximate a given integral. Each of these techniques provides a good approximation of the integral, but the accuracy of the approximation will depend on the function being integrated and the number of sub-intervals used.
