The heights of 10 year old children has a normal probability distribution with mean of 54.6 inches and standard deviation of 5.7
Fofino [41]

Answer:

a) 0.69

The probability that a randomly selected 10-year old child will be more than 51.75 inches tall

P(X>51.75 ) = 0.6915

Step-by-step explanation:

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

<em>Given mean of the Population = 54.6 inches</em>

<em>Given standard deviation of the Population = 5.7 inches</em>

<em>Let 'X' be the random variable of normal distribution</em>

Let 'X' = 51.75 inches

Z = \frac{x-mean}{S.D} = \frac{51.75-54.6}{5.7} = -0.5

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

<em>The probability that a randomly selected 10-year old child will be more than 51.75 inches tall</em>

<em>P(X>51.75 ) = P(Z>-0.5)</em>

                  = 1 - P( Z < -0.5)

                 =   1 - (0.5 - A(-0.5))

                =    1 -0.5 + A(-0.5)

               =    0.5 + A(0.5)    (∵A(-0.5)= A(0.5)

              =     0.5 +0.1915

              =  0.6915

<u><em>Conclusion</em></u>:-

<em>The probability that a randomly selected 10-year old child will be more than 51.75 inches tall</em>

<em>P(X>51.75 ) = 0.6915</em>

Tracy deposited $59 into a bank account that earned 3.5% simple interest each year. If no money was deposited into or withdrawn
Illusion [34]

Answer

Find out the how much money was in the account after 1\frac{1}{2} years.

To prove

Formula

Simple\ interest = \frac{Principle\times Rate\times time}{100}

As given

Tracy deposited $59 into a bank account that earned 3.5% simple interest each year.

Principle = $59

Rate = 3.5 %

Time = 1\frac{1}{2}

i.e

Time = \frac{3}{2}

Time = 1.5 years

Put all the values in the equation

Simple\ interest = \frac{59\times 3.5\times 1.5}{100}

                                 =  \frac{309.75}{100}[/tex]

                                = $3.1(approx)

Amount in the account = Principle + Simple interest

                                      = $59 + $ 3.1

                                      = $ 62.1

1 Dollar = 100 cent

Now convert $62.1 into cent.

= 62.1 × 100

= 6210 cent

Therefore the money in the account is 6210 cent .
