Lapatulllka [165]

Answer:

  • A, C, E

Step-by-step explanation:

<u>Options:</u>

A. m∠C + m∠E = m∠A

  • Correct. Exterior angle equals to sum of non-adjacent interior angles.

B.   m∠D + m∠F = m∠B

  • Incorrect. Exterior angles have greater value.

C. m∠B + m∠C + m∠E = 180°

  • Correct. Interior angles of a triangle sum to 180°

D. m∠B + m∠C + m∠D = 180°

  • Incorrect. Angles C and D sum to 180°

E. m∠A + m∠ B = m∠E + m∠F

  • Correct. Both sides of equation refer to straight angle.

F . m∠B + m∠C + m∠ E = m∠A + m∠D + m∠F

  • Incorrect. Some of interior angles is not equal to sum of exterior angles.

Question Help Of 515515 samples of seafood purchased from various kinds of food stores in different regions of a country and gen
Setler79 [48]

Answer:

(0.5848 ; 0.6552)

We are confident that about 58% to 66% of sea foods in the country are Mislabelled.

No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.

Step-by-step explanation:

Sample size, n = 51

p = 0.62

1 - p = 1 - 0.62 = 0.38

n = 515

Confidence level = 90% = Zcritical at 90% = 1.645

Confidence interval = (p ± margin of error)

Margin of Error = Zcritical * sqrt[(p(1-p))/n]

Margin of Error = 1.645 * sqrt[(0.62(0.38))/515]

Margin of Error = 1.645 * 0.0214

Margin of Error = 0.035203

Lower boundary = (0.62 - 0.035203) = 0.584797

Upper boundary = (0.62 + 0.035203) = 0.655203

(0.5848 ; 0.6552)

We are confident that about 58% to 66% of sea foods in the country are Mislabelled.

No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.

Which statement below is correct?
solniwko [45]

Answer:

The answer would most likely A.

Step-by-step explanation:

In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star. Most of the polygons sides are equal.

A polygon has the same number of sides and angles because they are closed figures with non-intersecting lines. Meaning, it would be the correct answer of A.

(If I'm correct, may I have brainliest?)

(If I'm wrong, please correct me.)
