There are 87 fewer fish in small school compared to big school.

We solve addition and subtraction problems by focusing on either the action (joining or separating) or the relationship in the problem. Many problems involve monetary relationships.

This week, we looked at COMPARISON problems, which involve determining the similarities and differences between sets.

Difference Unknown: One type of compare problem entails determining how many more items are in one set than another. James, for example, has six mice. Joy has eleven mice. Joy has how many more mice than James?

Given,

Number of fish in small school = 25

Number of fish in big school =  112

then,

Number of fewer fish does small school have 112 -25 = 87

Thus, there are 87 fewer fish in school than big school.

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.

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.

Answer: Ok so the slope is always going to be m and the y intercept will be the b.

Step-by-step explanation: For example the slope form in y=mx+b. Whatever is in that b spot is going to be the y-intercept. So for number one on exercise 7 the slope will be 2/3 and the y- intercept will be -4. Same for number 2 remember take your time and know that m is the slope and b is your y-intercept. I really hope this helps you.

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

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."

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.

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

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.

Number of bicycles Daniela rented = 6

So Profit for renting 6 bicycles = $([tex]25 \times 6 + 7[/tex]) = $157

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

Question 7:

Given that line PB is tangent to circle A, therefore, based on the tangent theorem, the measure of angle ABP = 90°.

To dilate an image , multiple the scale factor with the coordinates

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.

The resizing happens from a point called the center of dilation. It is the center of dilation from which the objects/figures are expanded or contracted.

Scale factor is a number by which the size of any geometrical figure can be changed with respect to its original size.

Follow the steps below to dilate an image.

Step 1: Determine the scale factor and the dilation centre.

Step 2: Identify an image vertex. Draw a line through one of the image's vertices from the centre of dilation.

Step 3: Determine the horizontal and vertical distances between the dilation centre and the vertex.

To find the horizontal and vertical distances from the centre of dilation to a new vertex, multiply the distances by the scale factor.

Step 4: Determine the new horizontal and vertical distances from the centre of dilation. Make a point plot.

Step 5: Join the new vertices together to create the dilated image.

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

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
