SUppose the total cost C(x) to manufacture a quantity x of insecticide (in hundreds of liters) is given by
Hitman42 [59]

Answer:

a) C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty).

b) C(x) decreases in (8\,s, 10\,s).

Step-by-step explanation:

Let C(x) = x^{3}-27\cdot x^{2}+240\cdot x +850, where x is the quantity of insecticide, measured in hundreds of liters, and C(x) is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of C(x) are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:

C'(x) = 3\cdot x^{2}-54\cdot x+240 (1)

Please notice that regions where C(x) is increasing has C'(x) > 0, whereas C'(x) < 0 when C(x) < 0.

We notice that C(x) is increasing in two regions: (i) (+\infty, 8\,s) and (ii) (10\,s,+\infty). Besides, C(x) decreases in (8\,s, 10\,s).

Nts) in a certain population of voters, 72% of them plan to vote in favor of a new
Ganezh [65]

Answer:

Probability that 10 of them plan to vote against this piece of  proposed legislation is 0.0701 or 7.01 %.

Step-by-step explanation:

Consider the event of voting against the piece as success, 'p'. So, voting in favor of the piece is failure and denoted by 'q'.

Given:

Sample size is, n=25

Probability of failure is, q=72\%=0.72

Therefore, probability of success is, p=1-q=1-0.72=0.28

Number of successes is, x=10

Now, from Bernoulli's distribution, probability of x successes out of n samples is given as:

P(X=x)=_{n}^{x}\textrm{C}p^xq^{n-x}

Here, n=25,x=10,p=0.28,q=0.72. Therefore,

P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{25-10}\\P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{15}\\P(X=10)=3.269\times 10^{6}\times 2.962\times 10^{-6}\times 7.244\times 10^{-3}\\P(X=10)=70.142\times 10^{-3}=0.0701=7.01\%

Therefore, probability that 10 of them plan to vote against this piece of  proposed legislation is 0.0701 or 7.01 %.

Complete the statements about the graph of a function.
Tom [10]

Answer:

See below

Step-by-step explanation:

When a graph is symmetric about the origin, it is an odd function (Ex: y=x³)

When a graph is symmetric about the y-axis, it is an even function (Ex: y=x²)

A function is considered even if f(x) = f(−x) and it is considered odd if f(-x)=-f(x).
