Frank's gross capital gain was $2,100.
What is gross capital gain?
the discrepancy between the overall cost base of your asset and your capital gains. Your share of the capital gain - If more than one person owns this asset, your share of the gain is equal to the percentage of the asset that you personally hold.
You want the gross capital gain resulting from selling a stock purchased for $6,150 and sold for $8,250.
Capital Gain
The capital gain resulting from the sale is the difference between the selling price and the purchase price:
gain = selling price - purchase price
gain = $8,250 -6,150
gain = $2,100
Frank's gross capital gain was $2,100.

We would like to estimate the proportion of uf students who owns a scooter to within 1% of the truth, with 95% confidence. We believe around 20% of students do. How many students should be sampled?.
It is determined that 188 students should be sampled to use the confidence interval for a proportion.
What is mean by the term confidence interval?A confidence interval is indeed the mean of the estimate plus and minus its variation.We get the very next confidence interval of percentages in a sample of n people surveyed with a success probability of π and a confidence level of.π ± z√π(1-π)/n
In which case,
z is indeed the z-score with the p-value of 1+α/2
The error margin is as follows:
M = z√π(1-π)/n
In this case:
z does have a p-value of at 95% confidence, so z = 1.96.Thus p = 0.2, a 20% estimate.Taking into account, this same sample size is n. M = 0.02.Then:
M = z√π(1-π)/n
0.02 = 1.96√0.02(1-0.02)/n
√n = 13.72
n = 188.23
To summarize:
A total of 188 students must be sampled to estimate the proportion of of students who owns a scooter.

Diabetes is significantly correlated with obesity.
Non-experimental or observational study designs include cohort designs. In a cohort study, the participants don't already have the desired result. They are chosen based on the person's exposure status.
A case-control study is a sort of observational research in which two existent groups with outcomes that differ from one another are found and compared on the basis of a purported causal factor.
An example of an observational study design is the cross-sectional study design. In a cross-sectional study, the researcher simultaneously assesses the participants' exposures and outcomes.

Find the value of “B,” that will make a perfect square trinomial. x² + Bx + 1.
*
Type the answer for B as a whole number.
Using algebraic identities, we found that for B=2 and B= -2 , the trinomial x² + Bx +1 makes a perfect square.
What are algebraic identities?Algebraic identities are the identities which aids in solving products or powers of algebraic expressions. Most common identities are :
(a+ b)² = a² + 2ab + b²
(a- b)² = a² - 2ab + b²
a² -b² = (a+ b) (a- b), where a and b can be variable or constants or algebraic expressions.
Let the perfect square of the trinomial be (x +a)²
x² + Bx +1 = (x+ a)² = x² + 2xa + a² (using identity (a+ b)² = a² + 2ab + b²)
⇒ x² + Bx +1 = x² + 2xa + a²
⇒ Bx = 2xa , a² =1
⇒B = 2a , a =± 1
if a =1 ⇒ B = 2
If a = -1 , B = -2
For B = 2 , x² + Bx +1 = x² + 2(1)x +1² = (x+1)² ( ∵(a+ b)² = a² + 2ab + b²)
For B = -2 , x² + Bx +1 = x² -2x + (-1)² = x² -2x +1 = ( x-1)² (∵(a- b)² = a² -2ab
+ b²)
Thus, the given trinomial x² + Bx +1 is perfect square when B =2 or -2

What is the percentage change from 5 to 2?
Answer:
the percentage change is a 60% change.
Step-by-step explanation:
A change from 5 to 2 represents a negative change (decrease) of -60%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
× 100%
Percent change = 2 - 5
|5|
× 100% =
-3
5
× 100 = -60% (decrease)
Where: 5 is the old value and 2 is the new value. In this case we have a negative change (decrease) of -60 percent because the new value is smaller than the old value.
What is -0.25 as a fraction in its simplest form
Answer:
-1/4
Explanation:
To write the decimal -0.25 as a fraction we need to multiply and divide by 100 as follows:
[tex]-0.25\times\frac{100}{100}=\frac{-0.25\times100}{100}=\frac{-25}{100}[/tex]We multiply by 100 because there are 2 digits after the decimal point.
Then, we need to simplify the fraction, so we can divide the numerator and the denominator by 25 as:
[tex]\frac{-25}{100}=\frac{-25\div25}{100\div25}=-\frac{1}{4}[/tex]So, the fraction in its simplest form is -1/4

Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w=0.75f . What does 0.75 tell us in this situation?
If the number of cups of water w, needed for f cups of flour is described by the equation w = 0.75f, 0.75 represents the number of cups of water needed for one cup of flour
The equation is
w = 0.75f
Where w is the number of cups waters needed for f cups of flour.
Here w is is dependent variable and f is the independent variable
We can see that w is proportional to the f, the 0.75 is the constant.
w = 0.75f
Move the f to left hand side of the equation
w/f = 0.75
Hence, If the number of cups of water w, needed for f cups of flour is described by the equation w = 0.75f, 0.75 represents the number of cups of water needed for one cup of flour

inequality which can be used to determine g, the number of gigabytes Mei Mei can
use while staying within her budget.
The flat cost of the plan = is $46 per month
Cost per gigabyte = $5 per gigabyte
Number of gigabytes = g
The maximum amount Mei Mei wants to spend on the bill = is $70 per month,
So, for each month,
$46 + $5(g) < $70
⇒ $5(g) < $70 - $46
⇒ $5(g) < $24
⇒ g < $24/$5
⇒ g < 4.8
The number of gigabytes to be used per month should be less than or equal to 4.8.

The shortest side is 22 meters in the mentioned quadrilateral.
Let us assume the length of first side be x. So, the other three sides of length will be (x + 1), (x + 2) and (x + 3). The perimeter is sum of all sides of the quadrilateral.
Keep the values in the formula of perimeter -
94 = x + x + 1 + x + 2 + x + 3
Performing addition on Right Hand Side of the equation
94 = 4x + 6
Shifting 6 to other side of the equation

Identify the slope and y intercept
Step-by-step explanation:
the y-intercept (b) is the easiest :
it is the y-value, when x = 0 : -3
the slope (m) is the ratio (y coordinate difference / x coordinate difference) when going from 1 point to another.
so, we need to identify 2 points in the line.
one we have already with b : (0, -3)
another is the x-axis intercept, which is clearly (4, 0)
the difference is not important, but we need to use the same for both (x and y).
I prefer to go from left to right, so from (0, -3) to (4, 0) :
x changes by +4 (from 0 to 4)
y changes by +3 (from -3 to 0)
the slope is +3/+4 = 3/4

Look at the distance vs. elevation graph. Describe the relationship between distance and elevation. Does the relationship support the continental drift theory? Provide at least one piece of support for your answer by referencing your graph
The relationship has no relation to continental drift theory, as it is a relation between distance and time, not distance and elevation.
What is continental drift theory?The continental drift theory states that the world's tectonic plates are in constant motion over time.
This is supported by the fact that some millions of years ago, there was only one continent, named Pangea, and now we have the continents as we know. These continents are also moving a small amount a year.
In this problem, the elevation decreases and the distance increases, however, the continental drift theory should have the distance increasing or decreasing over time, hence the graph relationship has no relation to the continental drift theory.

The starting point is 1,365 miles .
Given :
→ initial time of plane = 1.7 hours
→ initial speed = 140 mph
→ final time of plane = 9.6 hours
→ final speed = same = 140 mph
The initial displacement of the plane is :
distance = speed × time

The final displacement of the plane is :
distance = 9.6 × 140
= 1,344 miles
The angles between initial and final displacement is :
100° - 10 ° = 90 °
The distance of the plane from its starting point is calculated as follows

The coefficient of x2 is 12
The coefficient of x is -17y
Constant term is 6y2
So, we express the middle term -17xy as -9xy – 8xy
12x2 -17xy+ 6y2 = 12x2 – 9xy – 8xy + 6y2
