The cost of cleaning up pollution in a stream is given by

anastassius [24]

Answer:

p must be less than 100

Step-by-step explanation:

Let

c ----> the cost in dollars to clean the stream

p ----> percent of the stream

we have

$c=\frac{370,000}{100-p}$

Remember that the cost cannot be a negative number

and

the denominator cannot be a zero

$100-p > 0$

Solve for p

Multiply by -1

$-100+p < 0$

Adds 100 both sides

$p < 100$

therefore

p must be less than 100

The Eks Survey Company employs 2000 people to conduct telephone surveys. Because many people don't like to answer such surveys,

Kobotan [32]

Use the next formula to find the margin or error:

$MOE=z*\frac{\sigma}{\sqrt{n}}$

z is the critical value (For a 95% confidence level the z-score is 1.95998)

σ is the standard deviation

n is the sample size

$\begin{gathered} MOE=1.95998*\frac{20.4}{\sqrt{36}} \\ \\ MOE\approx6.6639 \end{gathered}$ <h2>Then the margin of error is: 6.6639</h2> $\begin{gathered} \bar{x}\pm MOE \\ \\ 38.6\pm6.6639 \end{gathered}$

A 6,000-liter cistern is empty when water begins flowing into it (at t = 0) at a rate (in L/min) given by Q`(t) = 9 √t, wher

lorasvet [3.4K]

Answer:

a) 6,455 L

b) V(t) = (18/3) * t^(1.5)

Step-by-step explanation:

Part a

Integrating the given relation from t = 0 to t= 105 mins

$V = \int {9 * \sqrt{t} } \, dt\\V = {\frac{9*2}{3}*t^(1.5) = \frac{18}{3}*t^(1.5)\\\\V = \frac{18}{3}*105^(1.5)\\\\\\V = 6,455L$

Part b

$V(t) = \frac{18}{3} * t^(1.5) + C\\Since V = 0 @ t = 0 ; hence, C = 0\\\\V(t) = \frac{18}{3} * t^(1.5)$
