Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The standard deviation is 
From the question we are told the confidence level is 94% , 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{1.881 } * 22 }{5} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.881%20%7D%20%2A%20%2022%20%7D%7B5%7D%20%5D%20%5E2)
=>
Answer:
18.56
Step-by-step explanation:
Answer:
0.7246 radians
Step-by-step explanation:
According to the Question,
Given that, a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches
- The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:
d = √{ (12)² +(15)² } = √(144+225) = √369inches
- The tangent of the angle is the ratio of the height of the box to this length
Tan∅ = 17/√369
Taking the 
, we have
∅ = (17/√369) ≈ 0.7246 radians
