Answer:
buddy its 2 cars :;)))
Step-by-step explanation:
This construction called a pencil of lines. That figure can have 3,4,5.... any number of straights lines. The main rule is their common point. And it looks like spokes of a wheel. Here you can find a lot of vertical angles and rays.
You could add two until you get to 512
Given :
p = 0.68
margin of error, E = 0.1
99% confident interval
alpha, α = 1 - 0.99
= 0.01
![$\frac{\alpha }{2}=\frac{0.01}{2} = 0.005$](https://tex.z-dn.net/?f=%24%5Cfrac%7B%5Calpha%20%7D%7B2%7D%3D%5Cfrac%7B0.01%7D%7B2%7D%20%3D%200.005%24)
∴
(z-critical value)
Sample size = ![$z_{\alpha/2} \times \frac{p(1-p)}{E^2}$](https://tex.z-dn.net/?f=%24z_%7B%5Calpha%2F2%7D%20%5Ctimes%20%5Cfrac%7Bp%281-p%29%7D%7BE%5E2%7D%24)
![$=(2.5758)^2 \times 0.68 \times \frac{(1-0.68)}{0.1^2}$](https://tex.z-dn.net/?f=%24%3D%282.5758%29%5E2%20%5Ctimes%200.68%20%5Ctimes%20%5Cfrac%7B%281-0.68%29%7D%7B0.1%5E2%7D%24)
![$= 6.63475 \times 0.68 \times \frac{0.32}{0.01}$](https://tex.z-dn.net/?f=%24%3D%206.63475%20%5Ctimes%200.68%20%5Ctimes%20%5Cfrac%7B0.32%7D%7B0.01%7D%24)
= 144.37
= 145 (rounded off)
Therefore, there are 145 businesses does she need to sample to meet this criteria.
Answer:52.0
Step-by-step explanation:you just add a decimal then a 0 because it is a whole number
