What is the difference between addition and subtraction of polynomials?

Both means are approximately equal at 1% level of significance.

What is significance level?

A finding has statistical significance in statistical hypothesis testing when it is highly unlikely to have happened given the null hypothesis.

H0: Mean of mean = mean of women

Ha: means of men < mean of women

(Left tailed test)

Since population std deviation is known but sample sizes are small t test is used.

The mean of Men minus Women equals -5.00

standard error of difference = 2.201

t = 2.2721

df = 53

p value= 0.0136

since p >0.01 at 1% significance level we fail to reject H0.

Both means are approximately equal at 1% level of significance.

The situation in which the value of the solution may be made infinitely large in a maximisation linear programming problem or infinitely small in a minimisation problem without violating any of the constraints is known as an unbounded solution

What is Linear Programming?

When a linear function is exposed to various constraints, it is maximised or reduced using the mathematical modelling technique known as linear programming.

Let's briefly define some situations

Infiniteness and semi-optimality, does not comply with what the situation exposes.

If there isn't a solution that satisfies all the requirements, the problem is said to be infeasible. As a result, this choice is not.

If the objective function can be improved indefinitely without going against the constraints and limits, then the problem is unbounded, and this is the right response.

The slope of a line is -1

What is a line ?

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.

A line is a perfectly straight, one-dimensional shape that extends infinitely in both directions and has no thickness. In order to stress that a line has no "wiggles" anywhere along its length, it is occasionally referred to as a straight line or, more formally, a right line (Casey 1893).

Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."

In this instance, we're assuming that we can use the following function to simulate the US GDP, or gross domestic product, in dollars:

[tex]GDP = 11(1.0220)^{t}[/tex]

We can also see that the exponential model formula given by: governs this formula.

[tex]GDP = 11(1.0220)^{t[/tex]

Where a denotes the starting sum, b the model's growth/decay rate, and t is the number of years since 1950.

The value of b in this instance is provided by:

b = 1.022

And when we calculated r as the growth rate, we obtained:

1.022 = 1 + r

r = 1.022 - 1

r = 0.022

Answer:

nope

Step-by-step explanation:

1 multiplied by 1/2 just equals 1/2 since it's being multiplied by one, it wouldn't matter if you kept multiplying 1/2 either because the numerator will stay the same regardless, and the denominator just gets bigger and bigger since you're multiplying by two. if the numerator wasn't 1 then I'm sure there's a possibility, but in this scenario, it's not.

Answer: You will reach 0

Step-by-step explanation:

Yes, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.

To see why this is the case, let's consider the following sequence of numbers:

1 * (1/2) = 0.5

0.5 * (1/2) = 0.25

0.25 * (1/2) = 0.125

0.125 * (1/2) = 0.0625

0.0625 * (1/2) = 0.03125

As you can see, each time we multiply by 1/2, the result is half of the previous number. Because any number multiplied by 0 is 0, we will eventually reach 0 if we keep multiplying by 1/2.

Therefore, if you start with 1 and repeatedly multiply by 1/2, you will reach 0.

6. Applying the inscribed angle theorem, x = 33

7. m<ABP = 90°.

m<APB = 48°

The tangent theorem states that the tangent of a circle is perpendicular to the radius of that circle and therefore forms a right angle at the point of tangency.

An inscribed angle has a measure that is half the measure of the intercepted arc, according to the inscribed angle theorem.

Therefore:

Question 6:

Based on the inscribed angle theorem,

Measure of arc AB = 2(x + 3) = 2x + 6

108 + 2x + 6 = 180 [semicircle]

Solve for x

114 + 2x = 180

2x = 180 - 114

2x = 66

x = 33

To find the amount of rain the meteorologist predicted, start by listing the key information from the problem.

The actual amount of rain was 1.5 inches.

The meteorologist's prediction was 20% less than that. This is the percent error.

First, find the amount of error. It is 20% of the actual amount of rain.

0.21.5=0.3

So, the amount of error in the meteorologist's prediction is 0.3 inches. Since the predicted amount was less than the actual amount, subtract 0.3 from the actual amount of rain.

1.5–0.3=1.2

The meteorologist predicted 1.2 inches of rainfall.

You could also find the meteorologist's rainfall prediction by finding 80% of the actual amount of rain.

0.81.5=1.2

The amount of rainfall the meteorologist predict is 1.2 inches

From the question, we have the following parameters that can be used in our computation:

Amount of rainfall = 1.5 inches

Prediction = 20% less than the amount of rainfall

These parameters imply that:

Prediction = Amount of rainfall * (1 - Percentage less)

Substitute the known values in the above equation, so, we have the following representation

Prediction = 1.5 * (1 - 20%)

Evaluate

Prediction = 1.2

Hence, the prediction is 1.2 inches

The net force is 126 kg m/s² needed to accelerate the llama on the stretcher.

To determine the net force needed to accelerate a llama weighing 200 kg on a stretcher with an upward acceleration of 0.63 m/s², we can use the formula F = ma, where F is the net force, m is the mass of the llama, and a is the upward acceleration of the stretcher.

As per the question, the mass of the llama is 200 kg and the upward acceleration of the stretcher is 0.63 m/s²,

So, the net force needed to accelerate the llama is:

F = 200 kg × 0.63 m/s²

F = 126 kg m/s².

By using the concept of profit, it can be calculated that-, Profit for renting 6 bicycles = $157

What is profit?

Profit is a financial gain earned when the revenue from a business activity exceeds the expenses associated with it. This gain is usually measured in monetary terms, but it could also be measured in terms of goods or services. Profit is the main reason why businesses exist and it can be used to reinvest in the business, pay shareholders, purchase new assets, or do other things. Profit is the lifeblood of any business and it is essential for sustaining and growing its operations.

For Daniela’s bicycle business the net profit (in dollars) for renting b bicycles is: P(b)=25b+7.

The 33rd term of the given Arithmetic progression will be -132.

What is an Arithmetic progression?

A series of numbers is called a "arithmetic progression" (AP) when any two subsequent numbers have a constant difference. Arithmetic Sequence is another name for it.

Given, first term= a1= 28

and, a93 = -432

we know that, a93 = -432

                   a + 92d = -432 (where d is the common difference)

                  28 + 92d = -432

                     92d = -432-28

                             = -460

                       d = -460/92 = -5.

Now, we can find the a33,

               a33 = a + 32d

                       = 28 + (32× -5)

                       = 28-160
