I don't know the options you were given, but I know that pi is a transcendental number. A transcendental number<span> is a </span>real<span> or </span>complex<span> number that is not </span>algebraic<span>—that is, it is not a </span>root<span> of a non-zero </span>polynomial equation<span> with </span>integer<span> (or, equivalently, </span>rational<span>) </span>coefficients<span>. The best-known transcendental numbers are </span>π<span> and </span>e<span>. Though only a few classes of transcendental numbers are known (in part because it can be extremely difficult to show that a given number is transcendental), transcendental numbers are not rare. Indeed, </span>almost all<span> real and complex numbers are transcendental, since the algebraic numbers are </span>countable<span> while the sets of real and complex numbers are both </span>uncountable<span>. All real transcendental numbers are </span>irrational<span>, since all rational numbers are algebraic. The </span>converse<span> is not true: not all irrational numbers are transcendental; e.g., the </span>square root of 2<span> is irrational but not a transcendental number, since it is a solution of the polynomial equation </span><span>x2 − 2 = 0</span><span>.</span>
Answer: D.) 3
Step-by-step explanation:
Given: Mean diameter: ![\mu=28\ cm](https://tex.z-dn.net/?f=%5Cmu%3D28%5C%20cm)
Standard deviation: ![\sigma=1.3\ cm](https://tex.z-dn.net/?f=%5Csigma%3D1.3%5C%20cm)
The required number of standard deviations is given by :-
![z=\frac{X-\mu}{\sigma}\\\\\Rightarrow\ z=\frac{31.9-28}{1.3}\\\\\Rightarrow\ z==3](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5C%5CRightarrow%5C%20z%3D%5Cfrac%7B31.9-28%7D%7B1.3%7D%5C%5C%5C%5C%5CRightarrow%5C%20z%3D%3D3)
Hence, a beach ball with a diameter of 31.9 cm is 3 standard deviations differ from the mean.
No solution . This problem makes no sense .
The second value of the ratio is guests, which is currently 3. To make this 30, you would multiply it by 10, and do the same to the first value, representing bouncy balls, to get the number of balls necessary for 30 people to maintain the same ratio. 9 * 10 = 90, so 90 balls would be required if the same ratio is to be kept.
There is 60 minutes in an hour. So 1/6th of that would be 10 mins.
