(a)

[tex]\begin{array}{cccccccc}x & {0} & {1} & {2} & {3} & {4}& {5} & {6} \ \\ {P(x)} & {0} & {4} & {8} & {12} & {16}& {20} & {24} \ \end{array}[/tex]

(b)

[tex]P(x) = 4x[/tex]

(c)

See attachment for graph

Step-by-step explanation:

Given

P(x) = Perimeter of square

Solving (a): Complete the table

The perimeter of a square is:

[tex]P =4x[/tex]

so, the table will be completed by multiplying each value of x by 4.

So, we have:

[tex]\begin{array}{cccccccc}x & {0} & {1} & {2} & {3} & {4}& {5} & {6} \ \\ {P(x)} & {0} & {4} & {8} & {12} & {16}& {20} & {24} \ \end{array}[/tex]

Solving (b): The equation

This has already been stated in (a)

[tex]P(x) = 4x[/tex]

Solving (c): The graph

Ana opened a bank account with $1000 that earns interest, compounded continuously, at an annual rate of r=0.02 . Money can be withdrawn from the account at regular intervals, and no additions to the account can be made. The function P models the balance of the account, in dollars, at time t. Assume that Ana withdraws money from the account continuously at a rate of N dollars per year.

Required:
Write down the differential equations that best describes the relationship between P and t?

Answers

Answer:

dp/dt = 0.02P-N

Step-by-step explanation:

[tex]\frac{p(t+t)}{nt}[/tex]

The differential equation that describes the relationship between P and t is:

dP/dt = rP - N

where P is the balance in dollars, t is time in years, r is the annual interest rate, and N is the rate of withdrawals in dollars per year.

What is a differential equation ?

A differential equation is an equation that relates an unknown function to its derivatives (or differentials) with respect to one or more independent variables. In other words, it is an equation that involves derivatives of an unknown function.

The rate of change of the balance P in the bank account is equal to the difference between the rate of interest earned on the account and the rate at which money is withdrawn from the account.

The rate of interest earned on the account is given by the continuous compounding formula:

dP/dt = rP

where r is the annual interest rate, P is the balance in dollars, and dP/dt is the rate of change of P with respect to time.

On the other hand, the rate at which money is withdrawn from the account is given by the expression:

dN/dt = N/T

where N is the rate of withdrawals in dollars per year, and T is the time interval in years between withdrawals.

If we assume that Ana withdraws money from the account continuously at a rate of N dollars per year, we can write:

N = dN/dt

Substituting this into the first equation, we get:

dP/dt = rP - dN/dt

Substituting the expression for dN/dt, we get:

dP/dt = rP - N/T

Simplifying, we get:

dP/dt = rP - N

which is the differential equation that describes the relationship between P and t.

The differential equation

dP/dt = rP - N

14x+5y=31
2x−3y=−29

Answers

Answer:

x = -1, y = 0=9

Step-by-step explanation:

Multiply the second equation by 7 and subtract the two.

14 x + 5 y = 31

- (14 x - 21 y = -203)

This gives 26 y = 234. Divide both sides by 26. y = 9

Then substitute y into any equation. I'll use

2 x - 3 y = -29

2 x -3(9) = -29

2 x - 27 = -29

2 x = -2

x = -1

The value 0.01 is the maximum safe level of some naturally occurring lethal pollutant in drinking water for human consumption. You need to decide if you will use water coming from a specific source for one of the beverages your company produces, based on sample measures of this pollutant taken in random different locations and times at the source of water. In this case you would want to _____.

Suppose that

H subscript o : mu less or equal than 0.01

H subscript alpha : mu greater than 0.01

A. maximize the power of the test

B. maximize beta

C. minimize mu

D. maximize the significance, alpha

E. maximize 1 minus alpha

Answer:

In this case you would want to _____.

D. maximize the significance, alpha

Step-by-step explanation:

The alpha (α) denotes the significance level or the probability of rejecting the initial or null hypothesis when it is true.

A higher alpha (α) reduces the probability of committing a Type II error or not rejecting the null hypothesis. On the other hand, a higher alpha (α) makes it more probable to reject a null hypothesis when it is true (Type I error).
