Answer:
347
Step-by-step explanation:
2(3) + 210 = 216
2(3) + 125 = 131
216+131 = 347
1. it says no more than 5 so that includes 5, so there are 5/8 probability
2.since this spinner stops on an even number (8) that means half are even and half are odd so 4/8, but you can reduce that to 1/2
3.since it says less than 3 there are only two so that ends up being 2/8 or 1/4 probability
Answer:
95% confidence interval for the proportion of preschool children vaccinated in that suburb lie between (.5042 , .6958) 0r 50.42% to 69.58%
Step-by-step explanation:
Given -
A random sample of 100 preschool children in Camperdown revealed that only 60 had been vaccinated
Sample size ( n) = 100
Sample proportion
=
= 0.6
confidence interval = 95%
1 -.95 = .05
=
= 1.96
95% confidence interval for the proportion of preschool children vaccinated in that suburb = ![\widehat{p}\pm z_{\frac{\alpha}{2}}\sqrt{\frac{\widehat{p} (1 - \widehat{p})}{n}}](https://tex.z-dn.net/?f=%5Cwidehat%7Bp%7D%5Cpm%20z_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%7D%5Csqrt%7B%5Cfrac%7B%5Cwidehat%7Bp%7D%20%281%20-%20%5Cwidehat%7Bp%7D%29%7D%7Bn%7D%7D)
= ![0.6\pm z_{\frac{.05}{2}}\sqrt{\frac{.6 (1 - .6}{100}}](https://tex.z-dn.net/?f=0.6%5Cpm%20z_%7B%5Cfrac%7B.05%7D%7B2%7D%7D%5Csqrt%7B%5Cfrac%7B.6%20%281%20-%20.6%7D%7B100%7D%7D)
= ![0.6\pm 1.96\times.0489](https://tex.z-dn.net/?f=0.6%5Cpm%201.96%5Ctimes.0489)
= ![0.6\pm .0958](https://tex.z-dn.net/?f=0.6%5Cpm%20.0958)
= (0.6 - .0958) , (0.6 + .0958)
= (.5042 , .6958)
Answer:
0.2&4
Step-by-step explanation:
There are 60 minutes in one hour, so 12 divided by 60 is the answer.
0.2 kilometers * 20 = 4
