The pressure, P (in lbs/ft2 ), in a pipe varies over time. Five times an hour, the pressure oscillates from a low of 90 to a high of 230 and then back to a low 90. The pressure at t = 0 is 90.

Question: Find a possible formula for P=f(t)

Answers

Answer 1

P=160-70*cos(2π*(1/12)*t)

Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

So, combining everything we get

P=160-70*cos(2π*(1/12)*t)

A rice merchant purchased 50 bags of rice at rupees 300 per back he spent 500 rupees towards transportation due to lack of demand for the Rice incurred a loss of 30% at what price should he sell it is bag of rice.

Plz put the answer with clear explanation.​

Answers

Answer:

10500 rupees

Step-by-step explanation:

So 50 bags 300 per pack so

300*50= 15000

15000 is what he spent on the 50 bags of rice

So he spent 500 rupees on transportation

15000 + 500 = 15500 total spent which is not needed but extra information

30% loss is 30% of 15000 so

30% of 15000 = 4500

15000 - 4500 = 10500 rupees

As society advances, what changes to the percentage sales tax structure do you envision will need to be adjusted and what would be the best way to make the adjustment?

Answers

As society gets more advanced, there would need to be a change to the percentage tax structure to make it more progressive so that the rich pay more taxes.  

The best way to make this adjustment is by passing laws.

How should taxes change as society advances?

As the society advances, there will be those who are richer and wealthier than others. They would need to take more care of society and the people who are not as fortunate as them because society would become more empathetic.

For this to happen, society would have to enact progressive tax rates where people who are wealthier pay more. This adjustment is best done by passing relevant taxation laws.

Answers

Answer:

Yes, this is a Binomial distribution, and the number of trials is 10.

Step-by-step explanation:

From the given information:

We are being told that ten students are chosen from a statistics class of 22 students.

If X represents the random variable for the number of students who got an "A" in the class.

Then we have two possible outcomes;

Number of students that got an "A" = (Success)

Number of students that did not get an "A" = (Failure)

Thus,  this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

Bernite is selling candy bars for a school fundraiser. The school paid $20.00 for a box of 15 king-size candy bars and Bernite sells then for $2.00 each. What is the relationship the amount of candy sold and the amount of money earned? (Multiple answer choice)

a. The relationship is linear
b. The relationship is non-linear
c. The relationship is proportional
d. The relationship always results in a positive profit.
e. The relationship always results in a negative profit

Answers

Answer:

e. The relationship always results in a negative profit

b. The relationship is non-linear

Step-by-step explanation:

From the question above it could be found that, the relationship always result in negative profit. This is because:

To the school purchase,

Selling price of Candy bars in a box = $20.00

On the other hand,

Each Candy bar cost = $2.00

No of Candy bars in a box = 15

Total cost = $2.00 x 15 = $30.00

Loss (negative profit) = Total cost - Selling price

= $30.00 - $20.00 = $10.00

This also shows that, the relationship is non-linear because there is no direct relationship between the selling price and the expected profit that was supposed to have been earned.

((5.6*10^(-3))*(7.7*10^(-9)))/((8*10^(-2))*(3.5*10^(-6)))=1.54*10^-4

then the other fraction one equals 9.45*10^-4

So the first expression goes into the second box.

For the second one, we have:
