Change divide sign to multiplication sign, and flip second fraction
= 41/21 × 23/8

multiply top numbers together and multiply bottom numbers together
= (42×23)/(21×8)
=943/168

You can do the multiplicative inverse by mutiplying 41/21 and 8/23. But, you have to switch the second number to 23/8. Once it's switched, you just multiples straight across. So, it is 943/168. Just simplify it

The mean number of words per minute (WPM) typed by a speed typist is 149149 with a standard deviation of 1414 WPM. What is the p
Semmy [17]

Answer:

The probability is  P(\=  X  >  x ) = 0.78814

Step-by-step explanation:

From the question we are given that

     The population  mean is  \mu  =  149

     The standard deviation is  \sigma  =  14

     The random number    x  =  147.81

      The sample  size is  n  = 88

The probability that  the sample mean would be greater than P(\=  X  >  x ) =  P( \frac{ \= x   -  \mu   }{\sigma_{\= x} }  > \frac{ x - \mu  }{\sigma_{\= x} }  )

Generally the z- score of this normal distribution is mathematically represented as

       Z  =  \frac{ \=  x   -  \mu  }{\sigma_{\= x} }

Now

        \sigma_{\= x } =  \frac{\sigma }{\sqrt{n} }

substituting values

         \sigma_{\= x } =  \frac{14 }{\sqrt{88} }

         \sigma_{\= x } =  1.492

Which implies that

         P(\=  X  >  x ) =  P( Z  > \frac{ 147.81  - 149   }{ 1.492}  )

        P(\=  X  >  x ) =  P( Z  > -0.80  )

Now from the z-table  the  probability is  found to be

        P(\=  X  >  x ) = 0.78814

Find the compound interest and final amount $950 for 2 years at 7½ per annum​
wlad13 [49]

Answer:

1092.50 account value

142.50 interest

Step-by-step explanation:

to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years

now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $

the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$
