Use the Law of Sines to solve the triangle. (Round your answers to two decimal places.)
B = 2° 45', b = 6.4, c= 5.3

The required proportion of side lengths is JK/LK= JM/LN.

The Side-Splitter Theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, then it splits those sides proportionally. In the case of triangle J K L, with line segment M N drawn parallel to side J L and intersecting sides J K and L K, the proportion of the lengths of the sides that are split can be determined by the ratio of the corresponding segments on each side.

Let's call the length of side J K as x, the length of side J L as y, and the length of side L K as z. Let the length of segment J M be a and the length of segment L N be b.

According to the side-splitter theorem, the proportion of the length of side J K to side L K is equal to the proportion of the length of segment J M to segment L N. This means that:

x/z = a/b

The surface area is approximately 100.5m².

Surface Area = πrl + πr²

Where r is the radius of the base and l is the slant height.

Surface Area = π(2m)(4m) + π(4m)²

Surface Area = 100.5m²

The surface area of a right circular cone can be calculated by using the formula surface area = πrl + πr². In this particular case, the height of the cone is 4m and the radius of the base is 2m. Therefore the surface area of the cone is calculated as follows: π(2m)(4m) + π(4m)² = 100.5m². This surface area includes both the base and sides of the cone.

The least count of Vernier calipers is 0.01cm and The length of the line is 10.23cm

Mean scale division:

The main scale is graduated with one division value equal to 1 mm. The length of the Vernier scale is the same as the n- scale of the Vernier scale and the (n-1) scale of the main scale.

Vernier Scale Division:

The minimum Vernier caliper number is also called the Vernier constant. Defined as the difference between the major and Vernier scales is represented mathematically as:

          VC = 1 MSD – 1 VSD

If the Vernier scale has n divisions, it matches the (n-1) divisions of the main scale. Vernier Caliper :

LC = ( 1 - [tex]\frac{n-1}{n}[/tex])  MSD

According to the problem

1MSD= 1mm

MSR = 10.2cm

Here, 10VSD  = 9MSD

          1VSD   = (9/10)MSD

                      =(9/10)×1mm

                      = (9/10)mm

Least count of Vernier calipers L.C = 1MSD - 1VSD

                                                           =1mm - (9/10)mm

                                                           =0.01mm

Therefore, Least Count (LC) = 0.01cm

Therefore,

Length of the line = MSR + (VSD × L.C)

                             = 10.2 + (3 × 0.01)

Therefore, the congruence theorem that may be employed to demonstrate that △WXZ and △YZX are equivalent is: AAS

Angles are considered congruent if the ratios of two shapes are equal. Similar to this, if the sides with one form are the same length and match the sides of yet another figure, the sides are congruent.

Here,

We are informed that ΔWXZ and ΔYZX share the same side.

The right angles ∠WXZ and ∠XZY are.

It is consistent for ∠XWZ and ∠XYZ.

Now that the parameters have been provided, we may infer that XZ is equal to itself according to the reflexive property for congruence, and as a result, we have a congruent side in each triangle.

Second, because ∠WXZ and ∠XZY were right angles, they are comparable and hence congruent to one another.

Finally, it is stated that ∠XWZ and ∠XYZ are congruent.

In conclusion, the triangles are identical according to the AAS Congruency since there are two corresponding angles one and corresponding sides that are both equal, but the comparable side wasn't with the included angles.

The can is a cylinder with the smallest height and a radius that is the square root of the volume divided by 2[tex]\pi[/tex].

The formula to calculate the volume of a cylinder is given by the product of the base area and its height. The volume of a cylinder = πr2h cubic units.

To find the dimensions of a 12-oz can that can be constructed with the least amount of metal, we need to minimize the surface area of the can while maintaining a volume of [tex]355 cm^3[/tex]. The surface area of a cylindrical can is given by [tex]2\pi r(r+h)[/tex] where r is the radius of the base of the can and h is the height of the can.

Minimizing the surface area of the can is equivalent to minimizing the total material used in constructing the can. This can be achieved by making the height of the can as small as possible while maintaining a volume of 355 cm^3. The volume of a cylindrical can is given by πr^2h,

So the equation is:

[tex]\pi r^2h= 355cm^3[/tex]

We can get the value of h in terms of r by dividing both sides by πr^2

[tex]h= 355cm^3 / (\pi r^2)[/tex]

Now we can substitute this value of h in the equation for the surface area:

[tex]2\pi r(r+h) = 2\pi r(r + 355cm^3 / (\pi r^2))[/tex]

Now we can differentiate the above equation with respect to r and set it equal to zero to find the minimum value of the surface area.

[tex]d(2\pi r(r+h))/dr = 2\pi r + 2\pi (355cm^3 / (\pi r^2)) = 0\\r = sqrt(355cm^3 / (2\pi ))[/tex]

Now we can substitute this value of r back into the equation for the volume of the can to find the corresponding value of h:

[tex]\pi r^2h = 355cm^3[/tex]

h = [tex]355cm^3 / (\pi r^2) = 355cm^3 / (\pi (355cm^3 / (2\pi ))^2)[/tex]

The dimensions of the 12-oz can that can be constructed with the least amount of metal are a radius of sqrt(355cm^3 / (2π)) and a height of 355cm^3 / (π (355cm^3 / (2π))^2).

Hence, the can is a cylinder with the smallest height and a radius that is the square root of the volume divided by 2π.

On solving the provided question, we can say that standard deviation 15.4 is the mean of the sample means' sampling distribution.

Standard deviation is a statistic that expresses the variability or variance of a group of numbers. While a high standard deviation suggests that the values are more dispersed, a low standard deviation suggests that the values tend to be closer to the established mean. A measure of how dispersed the data are from the mean is the standard deviation (or ). When the standard deviation is low, the data tend to be grouped around the mean, and when it is large, the data are more dispersed. The average variability of the data set is measured as standard deviation. It reveals the average deviation of each score from the mean.

We may apply the simple interest formula to find the due date for repayment from Mikos is 5 months.

I = P*r*t, where I represents interest, P the principal (initial sum), r the interest rate, and t the period of time in years.

The maturity value formula can be used to calculate interest given that the loan's principal is $100,000 and its maturity value is $104,375:

Where MV is the maturity value, P is the principal, and I is the interest, the formula is: MV = P + I.

With the above data, we obtain: 104,375 = 100,000 + I

  I = 4,375.

Now we can use this value of I to find the time t in years:

I = P*r*t

4,375 = 100,000 (0.105) t

t = 4.375 / (100,000 x 0.105)

t = 4.375 / 10,500

t = 0.417 years or approximately 5 months

 So, it takes approximately 5 months to repay the pay back amount .

Therefore, Mike must repay the amount by April 14, which is around five months after the day he took out the loan.

Each point in the plane whose distance from that other point is a certain value forms a circle (center). It is therefore a curve composed of vertices that are spaced apart from one another in the plane by a specific amount. Furthermore, it is symmetrical about the center at all angles in terms of rotation. The closed, two-dimensional plane of a circle has all pairs of endpoints equally separated from the "center." When a line is drawn through the circle, a circle symmetry line is created. Furthermore, it rotates equally from all angles about the center.

The answer is C) 195/8

First, we can use the fact that A, B, C, D, E, and F are concyclic and that D, E, and F are the midpoints of AB, BC, and AC respectively.

Let r be the radius of the circumcircle of triangle ABC. Then using the Pythagorean theorem, we can find that r = (151413) / (4*K) where K is the area of the triangle.

Now we can use the property that the perpendicular bisectors of any triangle pass through the circumcenter of the triangle. We know that the midpoint of a line segment is the foot of the perpendicular from that point to the other endpoint. Then we can use the property that the radius from the circumcenter of the triangle to the midpoint of a side is half the length of that side.

Therefore, the circumcenter of triangle BDE is located at X = (BD/2, DE/2) = (13/2, 7/2) and the circumcenter of triangle CEF is located at X = (CE/2, EF/2) = (15/2, 7/2).

So the coordinates of X are (13/2, 7/2) and since the circumcenter of a triangle is equidistant from each vertex of the triangle, we can find that XA = XB = XC = r = r = (151413) / (4*K)

Therefore, XA + XB + XC = 3r = 3(151413) / (4*K) = (195/8)

Statistic C has the highest variability compared to the other two dotplots, meaning it has a greater range of expected value. This indicates that it has both low bias and high variability, since the actual value of the population parameter is 5.

Statistic C has the highest variability among the three dotplots, indicating that it has the highest range of values. This suggests that it has both low bias and high variability, since the actual value of the population parameter is 5. This means that it is likely to provide the most accurate estimation of the population parameter. On the other hand, Statistic A and B have much lower variability, meaning that their range of values is more restricted. This suggests that they are more likely to be biased, as they are not as likely to accurately represent the actual value of the population parameter. The low variability of these two dotplots also suggests that they are less reliable than Statistic C.

statistic A

Step-by-step explanation:

A degree 3 polynomial has either 1 real root, 2 real roots, or 3 real roots. It is possible for the polynomial to have imaginary roots as well, but these are not counted.

A polynomial of degree 3 is a equation in the form of ax3 + bx2 + cx + d = 0. For a polynomial of degree 3, the number of roots it has depends on the value of the discriminant, which is calculated using the formula b2 - 4ac.  If the discriminant is positive, the polynomial has three real roots. If the discriminant is equal to zero, the polynomial has two real roots. If the discriminant is negative, the equation has one real root and two imaginary roots. In the case of one real root, the polynomial can be factored into (x - r) (ax2 + bx + c). In the case of two real roots, the polynomial can be factored into (x - r1) (x - r2). In the case of three real roots, the polynomial can be factored into (x - r1) (x - r2) (x - r3).
