You roll a number cube twice what is the probability of rolling a 2
The probability of getting a 5 from the first rolling is 1/6. The probability of getting an even number is 1/2 (= 1/6 (for a 2) + 1/6 (for a 4) + 1/6 (for a 6)). As the two rollings are independent, you can just multiply two probability values to come up with a final answer. That is, (1/6)·(1/2) = 1/12.

A class is collecting cans to recycle. their goal is to collect 200 ounces of cans. on the first day 3 student each bring in 12.7 ounces of cans, and 4 students each bring in 17.3 ounces of cans. how many more ounces of cans must be collected to reach the goal?
The student needs to calculate the total number of ounces collected by multiplying the number of students by the amount each student brought in, then add these totals together. The collection goal of 200 ounces minus this sum will equal the number of ounces left to be collected.
Explanation:To answer your question properly, we first need to calculate the number of ounces the students have already collected. The calculation goes as follows: (3 students * 12.7 ounces per student) + (4 students * 17.3 ounces per student). The result of these calculations will be the total ounces of cans brought in. To determine how many ounces of cans are left to be collected to reach the goal, we subtract this sum from 200, the collection goal in ounces. As these are basic arithmetic calculations, they present an example of how mathematics can be used to solve practical problems relating to the real-world context of the question.

1) From the total of 17 marbles, Jacob takes 2 out at random. There are
[tex]\dbinom{17}2=C(17,2)=C^{17}_2=\dfrac{P(17,2)}{2!}=\dfrac{P^{17}_2}{2!}=\dfrac{17!}{2!(17-2)!}=136[/tex]
possible outcomes of the draw. (Lots of different notations are used for the binomial coefficient; the first one is my preference.) The number of ways to draw exactly 2 orange marbles is
[tex]\dbinom70\dbinom{10}2=1\cdot1\cdot45=45[/tex]
That is, of the 3 red and 4 blue marbles - or the 7 non-orange marbles - we want 0; of the 10 oranges, we want 2.
So the probability of drawing exactly 2 orange marbles is [tex]\dfrac{45}{136}\approx0.33[/tex].
2) Now Jacob draws 3 marbles, for which there are
[tex]\dbinom{17}3=680[/tex]
possible combinations. The event that Jacob draws at least 1 orange marble is complementary to the event that Jacob draws 0 orange marbles. So if we find the probabilty of drawing 0 oranges, then we subtract this from 1 to find the probability of drawing at least 1.
There are
[tex]\dbinom73\dbinom{10}0=35\cdot1=35[/tex]
possible ways of doing, so the probability of drawing 0 oranges is [tex]\dfrac{35}{680}[/tex], in turn making the probability of drawing at least 1, [tex]1-\dfrac{35}{680}=\dfrac{645}{680}\approx0.95[/tex].
3) This question is kinda ambiguous. It's not clear whether Jacob draws a marble with or without replacement.
If he does return a drawn marble to the bag, then for each draw, there is a [tex]\dfrac{10}{17}[/tex] probability that he draws an orange marble, and a [tex]\dfrac7{17}[/tex] probability of not. The draws are presumably independent of one another, so that the probability of drawing the first orange marble on the fourth attempt would be
[tex]\dfrac7{17}\cdot\dfrac7{17}\cdot\dfrac7{17}\cdot\dfrac{10}{17}=\dfrac{3430}{83521}\approx0.041[/tex]
If no replacements are made, then as non-orange marbles are drawn from the bag, the number of non-oranges and the total number of marbles both decrease by 1. Then the probability of drawing orange on the fourth draw would be
[tex]\dfrac{\dbinom71\dbinom61\dbinom51\dbinom{10}1}{\dbinom{17}1\dbinom{16}1\dbinom{15}1\dbinom{14}1}=\dfrac5{136}\approx0.037[/tex]

5) We apply the inclusion/exclusion principle:
[tex]P(\text{wood OR chrome})=P(\text{wood})+P(\text{chrome})-P(\text{wood AND chrome})[/tex]
[tex]P(\text{wood OR chrome})=90\%+75\%-70\%=95\%[/tex]
6) The events of a boat having chrome accents and a boat being made of wood are independent if and only if
[tex]P(\text{wood AND chrome})=P(\text{wood})\cdot P(\text{chrome)}[/tex]

Hagrid plans to put up new fencing around his rectangular garden. He wants the width of his new garden to be 6 less than the length. The perimeter of the new garden will be 188 feet. Create and use an algebraic equation to find the dimensions (length and width) of Hagrid's new garden. Show your work!
Answer:
Lenght=50 feet.
Width=44 feet.
Step-by-step explanation:
1. He wants the width of his new garden to be 6 less than the length, this can be expressed as following:
[tex]W=L-6[/tex]
Where W is the width L is the length.
2. The perimeter of a rectangle can be calculated with:
[tex]P=2L+2W[/tex]
3. You know the perimeter, therefore, you can substitute [tex]W=L-6[/tex] into the equation of the perimeter and solve for the length:
[tex]2L+2(L-6)=188\\2L+2L-12=188\\4L=200\\L=50[/tex] (The length is 50 feet)
3. Then, the width is:
[tex]W=L-6[/tex]
[tex]W=50-6=44[/tex] (The width is 44 feet)

Which of the functions below could have created this graph?
Answer:
A
Step-by-step explanation:
Two facts need to guide your answer.
One
The highest power is odd: you know this because an even power would start on the left come down do it's squiggles if had any and wind up on the right going up.
This graph comes down on the left does it's squiggles and then goes further down on the right. That's the behavior of something whose highest power is odd.
Two
The leading coefficient, the number in front of the highest power must be minus. If it was positive as in y = x^3 the graph would be the mirror image of what it is.
Argument
B and D cannot be true. The highest power is even.
C is false because the leading coefficient is + 1.
So that leave A which is the answer.

The position graph shown in the question represents an object that is undergoing uniform motion. To create this graph, you would need a linear function that describes linear motion.
Explanation:The position graph shown in the question represents an object that is undergoing uniform motion. Uniform motion occurs when an object travels at a constant speed in a straight line. The graph shows a linear relationship between position and time, with the object consistently moving in the same direction.
To create this graph, you would need a function that describes linear motion. A linear function in the form of y = mx + b, where y represents position, x represents time, m represents the slope (rate of change of position with respect to time), and b represents the initial position. The slope of the line in the graph represents the speed of the object.
For example, the function y = 2x would create a position vs. time graph with a slope of 2, indicating that the object is moving at a constant speed of 2 units per time interval. Similarly, any other linear function with a constant slope could create this graph.

What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Marshall Earns a salary of $36,000, and each year he receives a $4,000 raise. Jim earns a salary of $51,000, and each year he receives a $1,500 raise.
Let x be the year in which they will get the same salary
Establishing the equation, we get
36000+4000x = 51000+1500x
Simplifying the equation,
36+4x = 51+1.5x
2.5x = 15
x = 6

In trapezoid ABCD AC is a diagonal and ∠ABC ≅ ∠ACD. Find AC if the lengths of the bases BC and AD are 14m and 28m respectively.
Answer:
[tex]AC=14\sqrt{2}m[/tex]
Step-by-step explanation:
we are given trapezoid ABCD
AC is a diagonal
∠ABC ≅ ∠ACD
we know that
BC and AD are parallel
so, <DAC = <ACB
so, ΔABC ≅ΔACD
Since, both triangles are similar
so, their ratios must be equal
we get
[tex]\frac{BC}{AC} =\frac{AC}{AD}[/tex]
now, we can plug values
[tex]\frac{14}{AC} =\frac{AC}{28}[/tex]
[tex]AC^2=14\times 28[/tex]
[tex]AC^2=14^2\times 2[/tex]
[tex]AC=14\sqrt{2}m[/tex]
To find the length of AC, the diagonal in trapezoid ABCD, we can use the fact that ∠ABC ≅ ∠ACD and the lengths of the bases BC and AD. By setting up a proportion using the corresponding sides of the similar triangles ABC and ACD, we can find that AB/AC = 1/2. Multiplying the length of AB by 2 gives us AC = 28m.
Explanation:Given that ∠ABC ≅ ∠ACD and the lengths of the bases BC and AD are 14m and 28m respectively, we can find the length of AC, which is a diagonal in trapezoid ABCD.
Because the two angles are congruent, triangle ABC is similar to triangle ACD. This means their corresponding sides are proportional.We can set up a proportion using the corresponding sides of the triangles:Find the equation (in terms of x) of the line through the points (-7,3),(-10,-3)
Answer:
y = 2x + 17
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
To calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 7, 3) and (x₂, y₂ ) = (- 10, - 3)
m = [tex]\frac{-3-3}{-10+7}[/tex] = [tex]\frac{-6}{-3}[/tex] = 2
y = 2x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 7, 3 ), then
3 = - 14 + c ⇒ c = 3 + 14 = 17
y = 2x + 17 ← equation of line
Solve for x.

Answer:
x=-12 and -3
Step-by-step explanation:
The quadratic formula is

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. We will substitute a=1, b=15 and c=36.
[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-15+/-\sqrt{(15)^2-4(1)(36)} }{2(1)}\\x=\frac{-15+/-\sqrt{225-144} }{2}[/tex]
We will now simplify and solve.

In a triangle the sides has 82 degrees ,2x+10 degrees and x degrees what is x
Answer:
x = 29 1/3 degrees
Step-by-step explanation:
A triangle has 3 angle that total 180 degrees.
The three angles given are 82 degrees ,2x+10 degrees and x degrees.
So,
82+ (2x+10) + x = 180
Combine like terms.
92 + 3x = 180
Subtract 92 from each side
3x = 180 -92
3x = 88
divide each side by 3
3x/3 = 88/3
Change 88/ 3 to a mixed number
3 goes in to 88 29 times with 1 left over.
x = 29 1/3 degrees

Autry made 45% of the shots he took during the basketball game. If he attempts 20 shots how many times did he score?
Final answer:
Autry scored 9 times during the basketball game by multiplying the shot percentage (0.45) by the total number of shots attempted (20).
Explanation:
The student's question is, how many shots did Autry score if he made 45% of his shots and attempted 20 shots in total? To calculate this, you can use the following steps:
Convert the percentage to a decimal by dividing by 100. So, 45% becomes 0.45.
Multiply this decimal by the total number of shots attempted. In this case, 0.45 multiplied by 20 shots.
The result gives you the number of successful shots Autry made.
So, performing the calculation:
0.45 × 20 = 9
Autry scored 9 times during the basketball game.

Answer: choice (3), x = (2b+7)/(a-b)
==============================
Explanation:
The idea is to get all the x terms to one side (after distributing), then factoring out the common term x, finally divide both sides by (a-b) as shown below
ax-7 = b(x+2)
ax-7 = bx+2b .... distribute
ax-7+7 = bx+2b+7 ... add 7 to both sides
ax = bx+2b+7
ax-bx = bx+2b+7-bx ... subtract bx from both sides
ax-bx = 2b+7
(a-b)x = 2b+7 .... factor out the GCF x
x = (2b+7)/(a-b) ... divide both sides by (a-b)
We have all of "2b+7" over "a-b" as one big fraction. This is what choice (3) is showing.

Jack's pancakes recipe calls for 2 teaspoons baking powder and 3 cups of flour. How how much baking powder is needed if Jack uses 9 cups of flour
Answer:
6
Step-by-step explanation:
Jack would need 6 teaspoons of baking powder for 9 cups of flour to maintain the ratio given in the original recipe.
To determine how much baking powder is needed if Jack uses 9 cups of flour instead of 3, you can set up a proportional relationship because the quantity of baking powder required is directly proportional to the amount of flour used.
If the original recipe calls for 2 teaspoons of baking powder for every 3 cups of flour, for 9 cups of flour (which is 3 times as much), you would need 3 times as much baking powder. Hence, the calculation would be as follows:
2 teaspoons baking powder / 3 cups flour = x teaspoons baking powder / 9 cups flour
By cross-multiplication, we can find the value of x:
2/3 * 9 = x
x = 2 * 3 = 6 teaspoons of baking powder
Therefore, Jack would need 6 teaspoons of baking powder for 9 cups of flour to maintain the ratio given in the original recipe.
Homer has four times as many hits in baseball than interceptions in football. Homer has made a total of 120 hits and interceptions. How many of each has Homer made? (Matrix on the calculator)
Answer:
If in football. Then Homer has made a total of 24 interceptions and 96 hits
Step-by-step explanation:
if we know that Homer has four times as many hits in baseball than interceptions that means how ever many interceptions he has its four times greater that that number so if he had 5 interceptions then you would do 5 x 4 and the number of hit would be 20 so if you already know the number of hits all together like we do you would divide by 5 cause the number of hits count as 4/5 and interceptions is 1/5 of that so we do 120/5 which gives us 24 and to find the number of hit we times that by 4 then we get 96 and to check our answer 96 + 24 = 120

Two spinners are shown to the right are spun. If the letters match you win otherwise you lose. What is the probability that you win? Use an area or tree diagram to help solve the problem.
Answer:
I really can't show a tree diagram on here, So i will come back to this question if I figure out how to do that.
Step-by-step explanation:
When spinning two matching-letter spinners with four letters each, there are 4 out of 16 possible outcomes where you win. Therefore, the probability of winning is 25%.
To calculate the probability of winning when spinning two matching-letter spinners, we need to know the number of possible outcomes and the number of successful outcomes.
If both spinners have the same set of letters, let's say A, B, C, and D, then there are a total of 4 x 4 = 16 possible outcomes when you spin both spinners (4 possibilities on the first spinner times 4 possibilities on the second spinner).
Out of these 16 possible outcomes, there are 4 outcomes where the letters match (A-A, B-B, C-C, D-D). So, there are 4 successful outcomes.
To find the probability of winning, you divide the number of successful outcomes by the total number of possible outcomes:
Probability of winning = (Number of Successful Outcomes) / (Total Number of Possible Outcomes) = 4/16 = 1/4 = 25%
So, the probability of winning when spinning two matching-letter spinners is 25%.

We see that in the first rational expression, both the numerator and denominator are divisible by 2. This means we can factor a 2 out of the top and bottom and then cancel it:
[tex](\frac{2(n)}{2(3n+2)})(\frac{3n+2}{3n-2})\\\\=(\frac{n}{3n+2})(\frac{3n+2}{3n-2})[/tex]
Now we can multiply straight across:
[tex]\frac{n(3n+2)}{(3n+2)(3n-2)}[/tex]
Since we have the same factor on the top and bottom, this factor cancels:
[tex]\frac{n}{3n-2}[/tex]
The numerator is n.
The numerator of the simplified expression is [tex]n[/tex].
Given:
The given expression is:
[tex]\left(\dfrac{2n}{6n+4}\right)\left(\dfrac{3n+2}{3n-2}\right)[/tex]
To find:
The numerator of the simplified expression.
Explanation:
We have,
[tex]\left(\dfrac{2n}{6n+4}\right)\left(\dfrac{3n+2}{3n-2}\right)[/tex]
It can be written as:
[tex]=\left(\dfrac{2n}{2(3n+2)}\right)\left(\dfrac{3n+2}{3n-2}\right)[/tex]
[tex]=\dfrac{2n(3n+2)}{2(3n+2)(3n-2)}[/tex]
[tex]=\dfrac{n}{3n-2}[/tex]
Therefore, the numerator of the simplified expression is [tex]n[/tex].
