a group of fish is called a school . there are twenty-five in the small school.there are one hundered twelve fish in the big school. how many fewer fish are in the small school
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.

at the 0.01 significance level, do women save more money than men? what is the value of the test statistic for this hypothesis test?
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.

What is meant by interquartile range?The middle two-thirds of your data set—the interquartile range, or IQR—contain the second and third quartiles. The interquartile range, as opposed to range, provides the range of the middle half of a data set. Range provides the spread of the entire data set. The statistical dispersion, or spread of the data, is measured in descriptive statistics by the interquartile range. In addition to the IQR, other names for it include the mid spread, middle 50%, fourth spread, and H-spread. The distinction between the data's 75th and 25th percentiles is what is meant by this term.

at the tesla automotive factory, a model s sedan is built using 4 tires, a main chassis, and 5 lithium-ion batteries. how many sedans can be made if there are 17 tires, 5 chassis, and 22 batteries?
The number of cars which can be made by using 4 tires, a main chassis, and 5 lithium-ion batteries are 4.
Using hit and trial method :
→ assuming tires as limiting substance
4 tires → 1 car
17 tires → 17/4 ×1 car
= 4.25 cars {reducing it to greatest integer value}
→ Assuming chassis as limiting theorem:
1 chassis → 1 car
5 chassis → 5 cars
→ Assuming batteries as limiting theorem substance:
5 batteries → 1 car

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.

Andrew has $20 saved and is working for $8
an hour. How many hours does he have to
work to save a total of at least $140?
Answer:
15 hours
Step-by-step explanation:
Firstly, Andrew has 20$ saved, right? So we should minus that by our goal, $140.
140-20=120
That leaves us with $120 to earn. Andrew works for $8 an hour. So we should divided 120 by 8 to get the number of hours he needs to work to get $140.
120÷8=15 hours
Which means that Andrew has to work for 15 hours to get a total of $140.

6. Applying the inscribed angle theorem, x = 33
7. m<ABP = 90°.
m<APB = 48°
What is the Tangent Theorem?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.
What is the Inscribed Angle Theorem?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°.
m<APB = 180 - 90 - 42
m<APB = 48°

How do you dilate an image?
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 llama weighing 200kg needs to be transported on a stretcher, The upward acceleration on the stretcher is 0.63m/s². What net force is needed to accelerate the llama on the stretcher?
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.

There are 1000 rabbits and chickens on a farm, and together they have 3150 legs. How many rabbits and how many chickens are there on the farm?.
The number of rabbits on the farm is 575 and the number of chickens is 425.
Here we have to find the number of rabbits and the number of chickens on the farm.
Data given:
Total number of rabbits and chicken = 1000
Number of legs = 3150
Let x be the number of rabbits and y be the number of chickens.
So we have
x + y = 1000 -------(1)
4x + 2y = 3150
A rabbit has 4 legs and a chicken has 2 legs.
2x + y = 1575 ------(2)
Substrating equation (1) from (2) we have:
x = 575
Now put in equation (1) we have:
575 + y = 1000
y = 425
Therefore the number of rabbits is 575 and the number of chickens is 425.
