calculate s2 (in gpa2) by using the computational formula for the numerator sxx.
To calculate the numerator sxx, which is part of a formula for calculating variance or sum of squares, additional information about the dataset or specific formula is needed.
The process involves finding the sum of squares of the data points by subtracting the mean from each data point, squaring the result, and summing up these squared differences. The formula used depends on the statistical method or context. Once sxx is determined, it can be used to compute the variance of the dataset. Variance measures the spread or variability of the data points around the mean and is obtained by dividing sxx by the degrees of freedom (n-1, where n is the sample size).

if you buy one march contract and sell one june contract, how much will you gain from the transactions based on the prices listed in the gold futures contract table? review later $400 $430 $380 $410
To determine how much you will gain from buying one March contract and selling one June contract, you need to calculate the difference in prices based on the gold futures contract table.
You will gain the difference between the prices of the March and June contracts. If March is at $400 and June is at $430, you'll gain $30 from these transactions ($430 - $400 = $30).
Follow these steps to calculate the gain from the transactions:
1. Locate the prices for the March and June contracts in the gold futures contract table. In this example, the March contract is priced at $400 and the June contract is priced at $430.
2. Calculate the difference in prices between the two contracts. Subtract the March contract price from the June contract price: $430 - $400 = $30.
3. The result from Step 2 represents the gain from buying one March contract and selling one June contract. In this example, you will gain $30 from the transactions.
It's important to note that this calculation does not account for any transaction fees or other costs associated with trading futures contracts. Additionally, gains and losses in futures trading can be amplified due to the use of leverage, so it's essential to consider risk management when trading futures.

Thus, f and g are inverse functions
Step-by-step explanation:
Inverse Functions
If two functions f(x) and g(x) are inverses, then it follows that:
\(f\circ g(x)=x\)
Or:
\(g\circ f(x)=x\)
We are given
\(\displaystyle f(x)=\frac{1}{4}x-6\)
\(g(x)=4x+24\)
Let's test if they are inverse functions:
\(f\circ g(x)=\frac{1}{4}(4x+24)-6\)
Simplifying:
\(f\circ g(x)=x+6-6=x\)
Now find:
\(\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24\)
Operating:
\(\displaystyle g\circ f(x)=x-24+24=x\)
Thus, f and g are inverse functions

Given: BE ≅ BD and AD ≅ CE. Prove: ΔABC is an isosceles triangle.
a. SSS (Side-Side-Side)
b. SAS (Side-Angle-Side)
c. CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
d. HL (Hypotenuse-Leg)
The statement that is true in the given is that if BE ≅ BD and AD ≅ CE then, ΔABC is an isosceles triangle.The triangles have three congruent sides, such as SSS (Side-Side-Side). If three pairs of sides are congruent, the triangles are identical (congruent)
.The third pair of angles must be congruent since the triangles are isosceles. CPCTC (Corresponding Parts of Congruent Triangles are Congruent) is the proof method to be used.CPCTC means that the parts of congruent triangles that correspond to one another are also congruent. In this situation, it means that AB is congruent to AC. So, by using the CPCTC theorem, we can conclude that ΔABC is an isosceles triangle with AB ≅ AC. Hence, option (c) CPCTC (Corresponding Parts of Congruent Triangles are Congruent) is the correct answer. The following is an explanation of this:In ΔABE and ΔCBD, we have BE ≅ BD (Given)AB ≅ CB (Common)∠ABE ≅ ∠CBD (Vertically opposite angles)Therefore, by SAS, we haveΔABE ≅ ΔCBDThus, AE ≅ CD (CPCTC)Similarly, in ΔADE and ΔCBE, we haveAD ≅ CEBE ≅ BD∠ADE ≅ ∠CEB Therefore, by SAS, we haveΔADE ≅ ΔCBEThus, AD ≅ CB and AE ≅ CDThus, AB + BC = AD + CDSince AD ≅ CDBut, CD = AE Therefore, AB + BC = AD + AEBut, AD + AE > ABTherefore, AB + BC > ABThus, BC > 0Thus, AB = ACTherefore, ΔABC is an isosceles triangle.

The correct answer is option (c) CPCTC (Corresponding Parts of Congruent Triangles are Congruent).
Given that BE ≅ BD and AD ≅ CE
To prove that ΔABC is an isosceles triangle.
It can be observed that by adding the two equations given above, we get AD + BE = CE + BD
If we see closely, this equation gives us two sides of the triangle ΔABC.
In other words, AD + BE represents side ABCE + BD represents side AC
Now, if we can show that BC = AB, then we can say that ΔABC is an isosceles triangle.
Now, since AD ≅ CE, it means that ΔABD ≅ ΔCBE (SAS)
Similarly, since BE ≅ BD, it means that ΔCBD ≅ ΔBDA (SAS)
Now, it can be observed that
AB = BD + DA (sum of two sides)
BC = BE + CE (sum of two sides)
Using the fact that BE ≅ BD, and AD ≅ CE and applying CPCTC, we can get BD = BE and CE = AD
Therefore, AB = BD + DA = BE + AD = BC
Therefore, it is proved that ΔABC is an isosceles triangle.
Hence the correct answer is option (c) CPCTC (Corresponding Parts of Congruent Triangles are Congruent).

\(6 + 5 + 3 + 1 = 15 \: marbles\)
Total number of possibilities excluding white marbles:\(6 + 5 + 1 = 12 \: marbles\)
The probability of an event occuring is given by:\(p(a) = \frac{number \: of \: possibilities}{total \: number \: of \: possibilities} \)
\(p(a) = \frac{12}{15} = \frac{4}{5} \)
Letter CAnswer:
The total number of marbles in the bag is:
6 blue marbles + 5 yellow marbles + 3 white marbles + 1 red marble = 15 marbles
The probability of not selecting a white marble can be calculated as follows:
Number of non-white marbles / Total number of marbles
There are a total of 15 - 3 = 12 non-white marbles in the bag (6 blue marbles + 5 yellow marbles + 1 red marble).
So the probability of not selecting a white marble is:
12 / 15 = 4/5

what is the maximum number of real zeros a polynomial function of degree three can have?
A polynomial can have as many real zeros as its degree, hence one with three degrees can have as many as three zeros.
What are the roots of an equation?The roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.
A polynomial with n degrees can have as many variables as n in total.
For example, a quadratic equation ax² + bx + c = 0 is a two-degree equation so it has a maximum of two roots or zeros.
A polynomial with the given degree structure will have exactly 3 roots because it has 3 degrees.
Hence "The maximum number of real zeros in a polynomial will be same as its degree thus 3 degrees will have 3 zeros".

3 cm
6 cm
1 cm

3 cm
2 cm
square centimeters
To find the area of the figure, we need to divide it into smaller rectangles and squares, and then sum their areas.
First, we can divide the figure into two rectangles, as shown:
```
+----+----+----+----+----+
| | | | | |
| | | | | |
+----+----+----+----+----+
| | | |
| | | |
+---------+---------+-----+
```
The left rectangle has dimensions 3 cm × 2 cm, so its area is:
A1 = 3 cm × 2 cm = 6 square cm
The right rectangle has dimensions 6 cm × 2 cm, so its area is:
A2 = 6 cm × 2 cm = 12 square cm
Now we can divide the left rectangle into two squares and a rectangle, as shown:
```
+----+----+----+
| | | |
| | | |
+----+----+----+
| | |
| | |
+----+---------+
| |

```
The top square has dimensions 2 cm × 2 cm, so its area is:
A3 = 2 cm × 2 cm = 4 square cm
The bottom square has dimensions 1 cm × 1 cm, so its area is:
A4 = 1 cm × 1 cm = 1 square cm
The remaining rectangle has dimensions 2 cm × 1 cm, so its area is:
A5 = 2 cm × 1 cm = 2 square cm
Finally, we can add up the areas of all the rectangles and squares to get the total area of the figure:
A = A1 + A2 + A3 + A4 + A5 = 6 cm^2 + 12 cm^2 + 4 cm^2 + 1 cm^2 + 2 cm^2 = 25 square cm
Therefore, the area of the figure is 25 square centimeters.
