9
Step-by-step explanation:
![4a+7\\\\a=\frac{1}{2}\\\\=4[\frac{1}{2}]+7\\\\=2+7\\\\=9](https://tex.z-dn.net/?f=4a%2B7%5C%5C%5C%5Ca%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C%5C%5C%3D4%5B%5Cfrac%7B1%7D%7B2%7D%5D%2B7%5C%5C%5C%5C%3D2%2B7%5C%5C%5C%5C%3D9)
X*log(4)=(x+2)*log(3)
Xlog(4)=xlog(3)+0.9542425094
Log(4)x-log(3)x=0.9542425094
0.1249387366x=0.9542425094
X=0.9542425094/0.1249387366/
X=7.637683
Answer:
<em>95% of the confidence interval for q is </em>
(0.05809 , 0.1183)
Step-by-step explanation:
<u><em>Step:1</em></u>
<em>Given that the random sample of 340 electronic components manufactured by a certain process is tested, and 30 are found to be defective.</em>
<em>sample proportion</em>
<em> </em>
<em></em>
<u><em>Step:2 </em></u>
<em>95% of the confidence interval is determined by</em>
<em></em>
<em></em>
<em></em>
<em></em>

(0.0882 - 0.03011 , 0.0882+0.03011)
( 0.05809 , 0.1183)
<u><em>Final answer:-</em></u>
<em>95% of the confidence interval for q is </em>
(0.05809 , 0.1183)
I’m not one hundred percent but I think it’s C
