Answer:

x+y = 10

Step-by-step explanation:

~~~\dfrac{53}{17}\\\\\\=3 \dfrac{2}{17}\\\\\\=3+ \dfrac{2}{17}\\\\\\=3+\dfrac{1}{\tfrac{17}2}\\\\\\=3+\dfrac{1}{8\tfrac 12 }\\\\\\=3+ \dfrac{1}{8+ \dfrac 12 }\\\\\\\text{By comparing with}~ 3 + \dfrac 1{x + \tfrac 1y},~ \text{we get}~ x = 8~ \text{and}~ y = 2.\\\\\text{Hence,}~ x +y = 8+2 =10.

Answer: 15

Step-by-step explanation:

Lets name the missing point as "x"

8^2 + x^2 = 17^2

=> 64 + x^2 = 289

=> x^2 = 289 - 64

=> x^2 = 225

=> x = 15

What is the following product? ^3 square root 24 times ^3 square root 45
torisob [31]

Answer:

6 \sqrt[3]{5}

Step-by-step explanation:

For the problem, \sqrt[3]{24} *\sqrt[3]{45}, use rules for simplifying cube roots. Under the operations of multiplication and division, if the roots have the same index (here it is 3) you can combine them.

\sqrt[3]{24} *\sqrt[3]{45} = \sqrt[3]{24*45}

You can multiply it out completely, however to simplify after you'll need to pull out perfect cubes. Factor 24 and 45 into any perfect cube factors which multiply to each number. If none are there, then prime factors will do. You can group factors together such as 3*3*3 which is 27 and a perfect cube.

\sqrt[3]{24*45} =\sqrt[3]{3*8*5*3*3}  = 6 \sqrt[3]{5}

Type the correct answer in the box. Round your answer to the thousandth place.
Alexandra [31]

Answer:

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)

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

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
