What is parallelogram?In Euclidean geometry, a parallelogram is a straightforward (non-self-intersecting) quadrilateral with two sets of parallel sides.
A parallelogram has equal-length opposing angles and facing or opposing sides.
The Euclidean parallel postulate or one of its equivalent formulations must be used in order to demonstrate the congruence of opposite sides and angles because both requirements flow naturally from this postulate.
A quadrilateral with only one pair of parallel sides, on the other hand, is referred to in British or American English as a trapezoid or trapezium.
We get,
The parallelepiped is a three-dimensional representation of a parallelogram.
So, 7 XS is the right response to the question.

how to calculate hyperboloid of one sheet?
The equation of hyperboloid of one sheet: \(\frac{x^{2} }{A^{2} } +\frac{y^{2} }{B^{2} } -\frac{z^{2} }{C^{2} } =1\) which is used to calculate hyperboloid.
The most challenging quadric surface is probably the hyperboloid of a single sheet. For starters, it is puzzling since its equation is quite similar to that of a hyperboloid with two sheets. For information on how to tell them apart, see to the section on the two-sheeted hyperboloid. Its cross portions are also highly intricate equation.

The standard deviation is _____ when the data are all concentrated close to the mean, exhibiting little variation or spread.
The standard deviation is relatively small when the data are all concentrated close to the mean, exhibiting little variation or spread.
The standard deviation could be a degree of the changeability or spread of a set of information. It is calculated by finding the square root of the normal of the squared contrasts between each information point and the cruel(mean).
In other words, it tells us how much the information values are scattered around the mean.
When the information is all concentrated near the cruel(mean), it implies that the contrasts between each information point and the cruel are moderately little.
This comes about in a little while of squared contrasts, which in turn leads to a little standard deviation. On the other hand, when the information is more spread out, it implies that the contrasts between each information point and the cruel are bigger.
This comes about in a bigger entirety of squared contrasts, which in turn leads to a bigger standard deviation.
For case, let's consider two sets of information:
Set A and Set B.
Set A:
2, 3, 4, 5, 6
Set B:
1, 3, 5, 7, 9
Both sets have the same cruel(mean) (4.0), but Set A encompasses a littler standard deviation (1.4) than Set B (2.8).
This is because the information values in Set A are all moderately near to the cruel(mean), while the information values in Set B are more spread out.
Subsequently, we will say that the standard deviation is generally small when the information is all concentrated near the mean, showing a small variety or spread.

Step-by-step explanation:
carrie and diana ate lunch at a restaurant. they ordered 1 pizza that cost $13.02. dianna ordered chicken wings for $12.99 and a drink for $3.25. carrie ordered a salad for $6.25 and a drink for $3.25. they left a $10.00 tip. diana paid for her food, plus half the cost of the pizza and half the tip. what was the total amount diana paid? show your work on the sketchpad or explain in the text box.
To find out how much Diana paid, we need to first calculate the total cost of the pizza, the chicken wings, the salad, the drinks, and the tip, and then divide that total by 2, since Diana is paying for half.
The total cost of the pizza, chicken wings, salad, and drinks is:
$13.02 (pizza) + $12.99 (chicken wings) + $6.25 (salad) + $3.25 (Diana's drink) + $3.25 (Carrie's drink) = $38.76
Adding the tip of $10.00 to this total gives:
$38.76 + $10.00 = $48.76
Half of this total is:
$48.76 / 2 = $24.38
Therefore, Diana paid $24.38 for her food, half the cost of the pizza, and half the tip.
Diana paid $19.65, which includes $9.02 for her share of the pizza, $5.00 for her share of the tip, $12.99 for chicken wings and $3.25 for a drink. Below is the working on the sketchpad.What is shown on the sketchpad?It is shown on the sketchpad below how Diana paid for her lunch at the restaurant.
The items that she paid for are indicated in the table below the sketchpad.What is the calculation for the amount Diana paid for lunch?Diana's share of the pizza is half of $13.02, which is $6.51. Adding $6.51 to the cost of the chicken wings and a drink gives a total of $22.75 for the cost of the lunch.
After adding the tip to the total cost of the lunch, we have $32.75 ($22.75 + $10.00 tip). To find the amount Diana paid, we need to find half of the total cost of the lunch and half of the tip.The following calculation shows the amount Diana paid:Her share of the cost of the lunch was $11.37 (($6.51 + $12.99 + $3.25)/2).Her share of the tip was $5.00/2, which is $2.50.The amount Diana paid for her food, plus her share of the cost of the pizza and tip is therefore $13.87 ($11.37 + $2.50).

What is the range of f(x) = 3* + 9?
{yly<9}
{yly > 9}
{yly > 3}
{yly <3}
Answer:
{y l y > 9}
Step-by-step explanation:
Given function:
\(f(x)=3^x+9\)
The given function is an exponential function.
The parent function is the basic equation before the function has undergone any transformation(s). Therefore, the parent function of the given function is:
\(f(x) = 3^x\)The range of the parent function is restricted to positive real numbers as it never takes a negative value. Furthermore, it never reaches zero (although it approaches y = 0 as x → -∞). Therefore, the range of the parent function is {y | y > 0}.
As the given function has been translated up 9 units (by the addition of "+ 9"), the range of the given function is translated 9 units up. So as x approaches negative infinity, y approaches (but never reaches) 9. Therefore, the range of the given function is:
{y | y > 9}The set of numbers 1, 7, 11 and 36 contains values for m. What value of m makes the equation below true?

The inequality the represents the expression -12d < - 6 is d < 1/2.
What is inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign. Equations are not always balanced on both sides using a "equal to" sign in mathematics. Occasionally it might be about a "not equal to" connection, meaning that something is superior to or inferior to another.
The given inequality is -12d < - 6.
The inequality can be written as:
d < -6/ -12
d < 1/2

Light sample A has a frequency of 4.30 ×1015 Hz and light sample B has a frequency of 8.70×1018 Hz. Based on frequency, which set gives the most correct description of the types of light for samples A and B respectively?
1) The wavelength of A is equal to 6.98 × \(10^{-8}\)meters

(10 pts) suppose i place 10 identical balls into 3 bins. each ball is placed independently with probability pi ≥0 of going into bin i; assume p1 p2 p3
To find the probability of the answer (placing 10 identical balls into 3 bins), we need to sum up the probabilities of all possible arrangements: ∑(Probability) for all valid combinations of x, y, and z
To solve this problem, we need to find the probability of placing the 10 identical balls into 3 bins. Each ball can be placed independently into one of the bins, with probabilities p1, p2, and p3.
To calculate the probability, we can use the principle of multiplication. We multiply the probabilities of each ball going into the respective bins.
Let's say we have x balls in bin 1, y balls in bin 2, and z balls in bin 3. We have the following conditions:
x + y + z = 10 (since we have a total of 10 balls)
x, y, z ≥ 0 (since each bin can have any number of balls, including 0)
We can use combinatorics to calculate the number of ways to distribute the balls among the bins. The formula is:
C(n + r - 1, r - 1) = C(10 + 3 - 1, 3 - 1) = C(12, 2)
This gives us the total number of possible arrangements of the balls in the bins.
Now, let's calculate the probability of each arrangement. We multiply the probabilities of each ball going into its respective bin:
Probability =\(p1^x * p2^y * p3^z\)
To find the probability of the answer (placing 10 identical balls into 3 bins), we need to sum up the probabilities of all possible arrangements:
∑(Probability) for all valid combinations of x, y, and z
In conclusion, we calculate the probability of placing 10 identical balls into 3 bins by multiplying the probabilities of each ball going into its respective bin and summing up the probabilities of all possible arrangements.
