If Anita has read 55 of the 245 pages in her book, what percent of the book has she read?
givi [52]

Answer:

22.45%

To two decimal places

Step-by-step explanation:

A book has 245 pages and she has only read 55 of the pages. To get the percentage:

55/245 and then multiply it by 100.

55/245

=O.2245 (To four decimal places)

0.2245 x 100

22.45% (To two decimal places)

She has only read 22.45% of the book. To convert it to a whole number, that's 22% of the book has been read

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X
slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em>                       </em>p = \frac{1}{6} =0.16

<em>                      q = 1-p =  1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

      μ = n p

     μ  =  12 (\frac{1}{6} ) = 2  

<em>The mean of the binomial distribution  = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

                σ = \sqrt{npq}

               σ = \sqrt{12(0.16)(0.84}

                  σ = 1.269

<em>The standard deviation of the binomial distribution</em>

<em>                </em> σ = 1.269

<u><em></em></u>

<u><em></em></u>
