The volume of the parallelopiped is 14 cubic units
What is the volume of a parallelopiped?The volume of a parallelopiped with vector sides a, b and c is given by
V = (a × b).c
We know that the parallelopiped has sides
a = (2, 1, 0)b = (3, - 1, 2) and c = (4, 0, 3)Thus, we proceed as follows
(a × b) = (2, 1, 0) × (3, -1, 2) = (2 × 3)i × i + (2 × -1)i × j + (2 × 2)i × k + (1 × 3)j × i + (1 × -1)j × j + (1 × 2)j × k + (0 × 3)k × i + (0 × -1)k × j + (0 × 2)k × k
Since
i × i = 0, j × j = 0, k × k = 0, i × j = k, j × i = -k, j × k = i, k × j = -i, k × i = j, i × k = -j,So, we have
(a × b) = (2, 1, 0) × (3, -1, 2) = (6) × 0 + (-2)k + -(4)j + 3i + (-1) × 0 + (2)i + -(3)j + -(0)i + (0) × 0
= 0 -2k - 4j + 3i + 2i - 3j - 0 + 0
= 5i -7j - 2k
= (5, -7, -2)
Since (a × b) = (5, -7, -2)
Thus, the volume of the parallelopiped is
V = (a × b).c
= (5, -7, -2).(4, 0, 3)
= 5 × 4 + (-7 × 0) + (-2 × 3)
= 20 - 0 - 6
= 14
So, the volume is 14 cubic units

A class of 118 students went on a field trip. They took 10 vehicles, some vans (x) and some buses (y). Find the number of vans and the number of buses they took if each van holds 6 students and each bus hold 35 students. Express your answer as a solution set {x, y} or (x, y).
Answer:
Solve for x+y=10
6x+35y=118
Step-by-step explanation:
I would solve it for you but my calculator isn't working rn. You could also use a picture calculator and it will give you a more in depth explanation. Hope this helps!
Answer:
{ 8, 2}
Step-by-step explanation:
Basic algebra, the object which is not in a set quantity, which we have to find, is the "some vans" and the "some buses"
So let the number of van be x
Let the number of buses be y
So, since there are 10 vehicles,
x+y=10
Makes sense right
Now, it says that every car can carry 6 students, and every van can carry 35 students, so in another way, we could represent this by saying
6 x Number of van + 35 x Number of buses
thus,
6x + 35y
And since 118 students went on the field trip, this means that
6x +35y = 118
So now we have two equations,
x + y = 10
6x + 35y = 118
We can solve this with substitution
x + y = 10
x = 10 - y
Thus, x = 10-y
Put this in this
6(10-y)+ 35y= 118
60-6y+35y=118
60+29y=118
29y=118-60
29y= 58
y = 58/29
y = 2
Thus, the number of buses, y, is 2
Now since there are 10 vehicles, and 2 are buses, then the other are 8 van

In a sample of 178 students at an Australian university that introduced the use of plagiarism-detection software in a number of courses, 51 students indicated a belief that such software unfairly targets students. Does this suggest that a majority of students at the university do not share this belief
Answer:
No it does not suggest that a majority of students at the university do not share this belief
Step-by-step explanation:
No it does not suggest that a majority of students at the university do not share this belief
It is so because we do not know what is the population of university students and how much 178 people relate to the actual population of the university.
Also, the sub set of 178 of the total university population do not represents the entire university population.

An office supply store is having a sale. Packages of paper are on sale for $4.60 per package. Regularly, they cost $5.75 per package.
What is the percent of decrease in the price of paper per package?
I need help
Answer:
20%
Step-by-step explanation:
Step 1: Subtract starting value minus the final value (decrease)
[tex]\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15[/tex]
Step 2: Divide the decrease by the original number
[tex]1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2[/tex]
Step 3: Multiply the result by 100 to get a percent decrease
[tex]0.2 \times 100\\\\= 20[/tex]
Therefore, the percent decrease of the price of paper per package is 20%
Note: If the percentage is negative, it means there was an increase and not a decrease.

An important application of regression analysis in accounting is in the estimation of cost. By collecting data on volume and cost and using the least squares method to develop an estimated regression equation relating volume and cost, an accountant can estimate the cost associated with a particular manufacturing volume. Consider the following sample of production volumes and total cost data for a manufacturing operation.
Production Volume (units) Total Cost ($)
400 4000
450 5000
550 5400
600 5900
700 6400
750 7000
Compute b1 and b0 (to 2 decimals if necessary). b1 b0 Complete the estimated regression equation (to 2 decimals if necessary).

Since the lengths EH and FG have the identical slope ratios as the parallel lines problem that is being given, assertion 4 is true, and so statement 4 is: EHFG.
Parallel Lines: What is it?Two non-vertical lines with the same slope that are located in the same plane are said to be parallel. Two parallel lines cannot cross each other. Right angles connections are those that intersect two non-vertical line in the same plane at a right angle.
Here,
The slope values in EH and FG are the same.
the exhibited proof, which is zero.
This implies that they follow one another in a straight line.
Since the sections EH and FG share the same gradient values as the parallel lines problem that is being given, assertion 4 is true, and so statement 4 is: EH||FG.

Answer:
for the first picture, the answer is A
Step-by-step explanation:
this is because it moves up 4, and 2 to the right, which means if it was to move 2 up, it will move 1 to the right. y - 2x, when you put it into y-intercept form, the equation will be y = 2x. which matches the points on the graph.
Answer: A. y = 2x
Step-by-step explanation: You can figure out the relationship between the x and y coordinates on the graph by imagining a line that runs through the given points and then figuring out the equation of the line in slope-intercept form by following the format of y=mx+b. "y" represents the output, "m" represents the slope (vertical change compared to the horizontal change), "x" represents the input, and "b" represents the y-intercept (where the line crosses the y-axis). Since the line is increasing, the slope is going to be positive. To get from the point at (0, 0) to the point at (2, 4), you go 4 units up and 2 units to the right; therefore, the value of "m" (slope) is 2, which is just the simplified version of 4/2. Since the line crosses the y-axis at (0, 0), the value of "b" is 0. With this information, the slope-intercept equation is y=2x+0. You can disregard the 0 in the equation since it does not have any affect on the graph since it holds no value. Now, the final equation is y=2x.
