What is a Congruent Polygon?

A polygon is said to be congruent if it has the same shape, sides that are the same length, and internal angles as the polygon it is being compared to. The criterion is satisfied if all of the congruent shapes are of the same type.

Pair 1: The polygons are identical in size and shape.

Pair 2: The polygons are identical in shape but vary in size.

Three: The polygons are the same size and shape.

Pair 4: The polygons are identical in shape but vary in size.

Here, pair 1 and pair 3 have congruent polygons.

Answer:

x = 10.2

Step-by-step explanation:

Formula:

a² + b² = c²

16² + b² = 19²

256 + b² = 361

b² = 361 - 256

b² = 105

b = 10.2

The surface area of that portion of the shape is 12 because since we are just talking about the surface area of one side, we can calculate it by just using the area of a triangle formula thus giving the answer of 12.

The length of her patio, the side of the house, is eight feet shorter than six times the width. Find the length and the width of the patio.


Thanks everyone!!

Answers

Answer:

what is the slope of the line shown?​

Answers

Answer:

I can's make out the line, but, you can plot two points, (try to make them whole numbers ie (3,6), (4,8)), subtract the point with the smallest x value from the other point ((4,8)-(3,6)=(1,2)) Divide the new y, by the new x (2/1), and you have your slope.

The Medassist Pharmaceutical Company uses a machine to pour cold medicine into bottles in such a way that the standard deviation of the weights is 0.15 oz. A new machine is tested on 71 bottles, and the standard deviation for this sample is 0.12 oz. The Dayton Machine Company, which manufactures the new machine, claims it fills the bottles with less variation. At the 0.05 significance level, test the claim made by the Dayton Machine Company.

If Dayton's machine is being used on a trial basis, should its purchase be considered?  C.V.(S) =  Test Statistic=   P-Value=   Decision: Conclusion:

answer :

i ) Cv(s) = 51.739

ii)  T = 44.8

iii)  p-value  = 0.0082

iv)   we do not fail to reject H0 ( since p-value < 0.05 )

v ) The new machine fills the bottles with a lesser variation

Step-by-step explanation:

we will test the hypothesis in regards to the standard deviation of the population

The hypothesis are    

H0 : б = 0.15

Ha : б < 0.15

hence at ∝ = 0.05    where n = 71

i) critical point for left sided test = [tex]x^2_{1-\alpha } , n - 1[/tex]

hence Cv(s) = 51.739

ii) Test statistic = T = ( n - 1 ) s^2 / б^2

 s = 0.12 , n = 71 , б = 0.15

hence T = 44.8

iii) P-value =  p ( [tex]x^{2} _{70}[/tex] < 44.8 )  = 0.0082

iv ) Decision : we do not fail to reject H0 ( since p-value < 0.05 )

v ) conclusion : The new machine fills the bottles with a lesser variation
