Type the correct answer in the box. Round your answer to the thousandth place.
kupik [55]

Answer:

<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Probability that carbon emissions from the company’s factory exceed the permissible level = 35% = 0.35

Accuracy of the test of emissions level = 85% = 0.85

2. The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is?

These two events, carbon emissions from the company’s factory and the accuracy of the test are independent events, therefore:

Probability that carbon emissions from the factory are within the permissible level = 1 - 0.35 = 0.65

Probability that the test predicts the opposite to be true = 0..35 * 0.85 = 0.2975 (The opposite is that the carbon emissions from the company exceed the permissible level)

Probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is:

0.65 * 0.2975 = 0.193375

<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>

Helen [10]

Incomplete Question the Complete Question with figure is below.

Answer:

The correct option is C . 48°

Therefore,

measure angle U is 48°.

Step-by-step explanation:

Given:

ΔEFG ~ ΔTUV

∠ F = 48°

To Find:

measure angle U = ?

Solution:

When the two Triangles are Similar then their Vertices are correspondence to each other. the correspondence of vertices are as

For, ΔEFG ~ ΔTUV  

E ↔ T

F ↔ U

G ↔ V

Also Corresponding angles of Similar Triangles are Congruent.

Therefore

∠F ≅ ∠U       Corresponding angles of Similar Triangles are Congruent.

But ∠ F = 48°     ......Given

∴ ∠U = 48°        ...........Transitive Property

Therefore,

measure angle U is 48°.
