vesna_86 [32]

Answer:

The number of people needed  is n =684  

Step-by-step explanation:

From the question we are told that

  The population proportion is  p = 0.65

   The margin of error is  E = 0.03

From the question we are told the confidence level is  90% , hence the level of significance is    

      \alpha = (100 - 90 ) \%

=>   \alpha = 0.10

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.645

Generally the sample size is mathematically represented as

       n =[ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1-p)

=>    n =[ \frac{1.645 }{0.03} ]^2 * 0.65(1-0.65)

=>    n =684

Upon hitting a bat, a baseball has a change in momentum of 16.5 kg-ms. What is the average
olya-2409 [2.1K]

Answer:

The average force applied to the baseball is 8.25kN

Step-by-step explanation:

This problem bothers on the impulse of a force

We know that the change in momentum is expressed as

Ft= mv-mu

Given

Ft=16.5 kg-ms

Time t of impact =0.00200s

The force applied can be solved for

By making F subject of formula

F= (mv-mu)/t

F=16.5/0.002

F= 8250N

F= 8.25kN
