Answer:

theoretical probability

Step-by-step explanation:

This is theoretical probability. The 7 pieces of paper each bear one number from {1, 2, ... , 6, 7}. There is only one piece of paper marked 7. So the probability of drawing a 2 is 1/7.

The figure below shows a shaded circular region inside a larger circle: A shaded circle is shown inside another larger circle. T

Taya2010 [7]

Area of larger circle: 3.14 x 5^2 = 78.5

Area of small circle: 3.14 x 2^2 = 12.56

Difference of the 2 areas: 78.5 - 12.56 = 65.94

Probability of being in large circle but not small circle: 65.94 / 78.5 = 0.84 = 84%

The answer is A) 84%

Can someone solve this with steps cause idk how to solve the radicals

IceJOKER [234]

$\bf 343^{\frac{2}{3}}+36^{\frac{1}{2}}-256^{\frac{3}{4}}\qquad \begin{cases}
343=7\cdot 7\cdot 7\\
\qquad 7^3\\
36=6\cdot 6\\
\qquad 6^2\\
256=4\cdot 4\cdot 4\cdot 4\\
\qquad 4^4
\end{cases}\\\\\\ (7^3)^{\frac{2}{3}}+(6^2)^{\frac{1}{2}}-(4^4)^{\frac{3}{4}}
\\\\\\
\sqrt[3]{(7^3)^2}+\sqrt[2]{(6^2)^1}-\sqrt[4]{(4^4)^3}\implies \sqrt[3]{(7^2)^3}+\sqrt[2]{(6^1)^2}-\sqrt[4]{(4^3)^4}
\\\\\\
7^2+6-4^3\implies 49+6-64\implies -9$

to see what you can take out of the radical, you can always do a quick "prime factoring" of the values, that way you can break it in factors to see who is what.

A library shelf is 9 feet wide.a set of nature books fill 1/6 of the shelf space. each book in the set is 3/5 inch thick.how man

Charra [1.4K]

Area filled by nature books = 1/6 of 9 feet = 1/6 x 9 = 3/2 feet.

Number of nature books = 3/2 / 3/5 = 2.5 ≈ 3 books.
