Is vuw similar to vxy? if yes, explain how you know. if no, explain why not.
Semenov [28]

Answer:

Yes, because m<UVW is congruent to m<XVY and m<VUW is congruent to m<VXY

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

so

In this problem

we know that

m< VUW=55\°

the measure of angle VXY is equal to

m -----> by supplementary angles

m

therefore

m< VUW=m

Remember that

m<UVW=m<XVY -----> is the same vertex

therefore

Triangles VUW and VXY are similar by AAA Similarity Theorem ( the three angles are congruent)

Observed and predicted values of a variable Y based on a sample of size n=9 and a forecasting model are given below. Compute sam
navik [9.2K]

Answer:

\bar{Y} = 17.2667

S_y^2 = 3.8626

MAD = 8.6778

SME = 535.3322

Step-by-step explanation:

The sample mean for a finite set of values is given by:

\bar{Y} = \frac{1}{n} \sum{y_i} = 17.2667

The standard deviation for a finite set of values is given by:

S_y^2 = \frac{1}{n-1} \sum (y_i - \bar{y})^2 = 3.8626

The MAD for a set of predicted values is given by:

MAD = \frac{1}{n}\sum|y_{predicted} - y_{real}| = 8.6778

The MSE for a set of predicted values is given by:

SME = \frac{1}{n}\sum(y_{predicted} - y_{real})^2 = 535.3322

Please please help me out!!!!
nikklg [1K]

Answer:

593.0 cm³

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = area of triangular end face × length

A of Δ = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here b = 10.2 and h = 10. 2

A of Δ = 0.5 × 10.2 × 10.2 = 52.02 cm², hence

V = 52.02 × 11.4 ≈ 593.0 cm³
