A common concern for students (and teachers) is the assignment of grades for essays or term papers. Because there are no absolut

e right or wrong answers, these grades must be based on a judgment of quality. To demonstrate that these judgments actually are reliable, an English instructor asked a colleague to rank-order a set if term papers. The ranks and the instructor's grades for these papers are as follows:
Rank: 1, 2, 3, 4, 5, 6,7,8,9,10, 11
Grade: A,B, A, B, B, C,D, C,C,D, E
A) Compute the Spearman correlation for these data.
B) Is there a significant correlation between the two instructors' judgments of the papers. Use a two tailed test with alpha = 0.05

The volume of this right prism is 2,500 ft³. What is the height, x, of the prism? x = ft
Natalka [10]

The height x of the right prism is 10 ft if the volume of this right prism is 2,500 ft³.

<h3>What is a rectangular prism?</h3>

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

From the figure:

Volume = 2500 cubic ft

(10)(x)(25) = 2500

250x = 2500

x = 10 ft

Thus, the height x of the right prism is 10 ft if the volume of this right prism is 2,500 ft³.

The minor arc measures of circle Z are shown in the figure.
DerKrebs [107]

The completed statement are:

  • Angle UZT is congruent to angle TZY.
  • Angle VZW is congruent to angle YZX.

<h3>What is the angle about?</h3>

Part A:

Angle UZT is congruent to angle TZY.

Using the image attached figure, we can see that:

∠UZT = 54°

∠TZY = 54°

Hence one can say that ∠TZY = ∠UZT are both congruent angles.

Part B:

Angle VZW is congruent to angle YZX.

Using the image attached attached, we can see that:

∠VZW = 71°

∠YZX = 71°

Hence, ∠YZX = ∠VZW are both  regarded as congruent angles .

Therefore, The completed statement are:

  • Angle UZT is congruent to angle TZY.
  • Angle VZW is congruent to angle YZX.
