Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The rough estimate of the standard deviation is 
The interval width is 
Generally the margin of error is mathematically represented as

=> 
=> 
From the question we are told the confidence level is 99% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [\frac{ 2.58 * 0.14 }{0.02} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B%202.58%20%2A%20%200.14%20%7D%7B0.02%7D%20%5D%20%5E2)
=> 
Answer:
Yes.
Step-by-step explanation:
Although there is not much info on this question, if you were to assume that there are 3 different answers or 3 different methods of solving that problem, it is definitey possible to assume that this is possible.
<span>The correct answer is option B. i.e. Transitive property. According to the transitive property of equality, if 8=x and x= y then, y = 8. This is mainly used in algebra and this property is a part of equalities and inequalities.</span>
Answer:
x = 63
Step-by-step explanation:
We can find the value of x by multiplying the difference of large arc to small arc with 1/2
if a = 117° then the large arc would be 243
1/2 × (243 - 117) = 63
