Answer: v(x)=31x


Step-by-step explanation:

Given Functions: e(x)=x^2+6x+21

m(x)=8x\\\\v(x)=31x

At x=4

e(4)=(4)^2+6(4)+21\\=16+24+21=61\\\\m(4)=8(4)=32\\\\v(4)=31(4)=124

here we can see v(4) has the largest value of 124 at x=4 .

Therefore, v(x)=31x is the function which has the largest value at x=4.

e(4)=4^2+6 \times 4+21=16+24+21=61 \\ \\
m(4)=8 \times 4=32 \\ \\
v(4)=31 \times 4=124

v(x) has the largest value when x=4.

Answer:

(0.4958, 0.7422)

Step-by-step explanation:

Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is \hat{p}=26/42=0.6190. The estimated standard deviation is given by \sqrt{\hat{p}(1-\hat{p})/n}=\sqrt{(0.6190)(1-0.6190)/42}=0.0749. Because we have a large sample, the 90% confidence interval for p is given by 0.6190\pm z_{0.05}0.0749 where z_{0.05}=1.6448 is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is 0.6190\pm (1.6448)(0.0749), i.e., (0.4958, 0.7422).
