Answer:
x=62
Step-by-step explanation:
This is a straight angle so they have to add up to 180.
124+x-6=180
118+x=180
x=180-118
x=62
Answer:
The sample should be as large as 480
Step-by-step explanation:
Probability of having a flu, p = 43/334
p = 0.129
Margin Error, E = 0.03
Confidence Interval, CI= 95%
At a CI of 95%, ![z_{crit} = 1.960](https://tex.z-dn.net/?f=z_%7Bcrit%7D%20%3D%201.960)
The sample size can be given by the relation:
![n = p(1-p)(z/E)^{2}](https://tex.z-dn.net/?f=n%20%3D%20p%281-p%29%28z%2FE%29%5E%7B2%7D)
![n = 0.129(1-0.129)(1.960/0.03)^{2} \\n = 479.59\\n = 480](https://tex.z-dn.net/?f=n%20%3D%200.129%281-0.129%29%281.960%2F0.03%29%5E%7B2%7D%20%5C%5Cn%20%3D%20479.59%5C%5Cn%20%3D%20480)
140-180÷1-5. -40÷-4= 10. 140=10(1)+b. b= 130. y= 10x+130
Answer:
1.
Hope that my answer helped! (By the way, I know for a fact that this is correct!)
