The possibility that Jacinta will choose the green marble is 45.5%
What is probability?Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.
Given that, Jacinta has 2 blue marbles, 4 red marbles and 5 green marbles in a bag, all the marbles are the same size,
We need to find the possibility that Jacinta will choose the green marble,
So, here we will use the concept of probability, probability tell us the chances of happening of an event.
The formula =
Probability = favorable outcomes / total outcomes.
Here, the favorable outcomes = green marble (5)
The total outcomes = total number of marbles = 5+4+2 = 11
So, P(getting the green marble) = 5/11 = 0.454545 = 45.5%
Hence, the possibility that Jacinta will choose the green marble is 45.5%

The value of x and y in equations 17x - y = 40 and 2x + 4y = 50 are x = 3 and y = 11.
What is equation ?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.
17x - y = 40 ⇒ (1)
2x + 4y = 50 ⇒ (2)
(1)* 4
68x - 4y = 160
Adding equation (1) and (2)
68x - 4y = 160
2x + 4y = 50
⇒ 70 x = 210
x = 3
Substituting the value of x in equation (1)
17*3 - y = 40
51 - y = 40
-y = 40 - 51
-y = -11
y = 11

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The angle of elevation to the top of a tree is 22°.
And, The angle of depression to the base of the tree is 12°.
Now,
Let the height of the rock ledge = x
So, By figure, we get;
⇒ tan 12° = x / 96
⇒ x = 96 × tan 12°
⇒ x = 20.35 meters
And, Let total height of the tree = x + y
= 20.35 + y
Hence, By figure, we get;
⇒ tan 22° = y / 96
⇒ y = 96 × tan 22°
⇒ y = 96 × 0.40
⇒ y = 38.4 meter
Thus, The height of tree = 38.4 meters + 20.35 meters
= 58.75 meters

To find:-
The height of the rock ledge.Height of the tree .Answer:-
Part A :-
Here we can see that the distance between the rock ledge and the base of the tree is 96m . Also the angle of elevation to the top of the tree from the rock is 22° .
Firstly, we can see that,
[tex]\implies \angle CAD =\angle EDA = 12^o\\[/tex]
This is so because they are alternate interior angles .
Now , in ∆ADE ,
[tex]\implies \tan\theta =\dfrac{p}{b}=\dfrac{AE}{ED}\\[/tex]
[tex]\implies \tan 12^o =\dfrac{AE}{96m} \\[/tex]
[tex]\implies AE = 96\tan12^o m \\[/tex]
[tex]\implies AE = 96 (0.21)m \\[/tex]
[tex]\implies AE = 20.16 \ m \\[/tex]
Hence the height of the rock ledge is 20.16 m.
_______________________________________
Part B :-
Now in ∆ACB , we have;
[tex]\implies \tan\theta =\dfrac{BC}{AC} \\[/tex]
[tex]\implies \tan 22^o =\dfrac{BC}{96m} \\[/tex]
[tex]\implies BC = 96\tan 22^o \ m \\[/tex]
[tex]\implies BC = 96(0.4) m \\[/tex]
[tex]\implies BC = 38.4 \ m \\[/tex]
Now the total height of the tree will be = BC + AE
[tex]\implies h_{tree}= BC + AE \\[/tex]
[tex]\implies h_{tree}=38.4\ m + 20.16 \ m =\boxed{58.56\ m} \\[/tex]
Hence the height of the tree is 58.56m.

Help please
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.
How do you find the linear inequality of a graph?The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed.
To determine the equation governing the inequality line, enter your slope and a point into the formula y = mx + B, where "m" denotes the slope, "x, y" denotes a point on the line, and "b" is the y-intercept. By inserting (0, 0), you get 0 = 0 + b, which equals 0.
When you rewrite the equation, you get y = x/2. The linear inequality x - 5 > 3x - 10 is an illustration. Due to the greater than symbol being utilised in this inequality, the LHS is clearly greater than the RHS.

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

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.

From the classification angles, it was possible to find the arcs:
UL=40, UY= 90, TY=50, YLE =270, LE=140 and UET=220.
UETIf UE= 180 and TE=40, you have:
UET=UE+TE
UET=180+40
UET=220
Classification AnglesThey are a lot of classifications for angles like complementary angles, supplementary angles, right angles, and others. See below:
complementary angles - two angles whose sum is equal to 90°.supplementary angles - two angles whose sum is equal to 180°.right angles - angles whose measure is 90°.opposite angles - opposite angles consequently they are congruent.The question gives mTE=40, and it asks:
ULUL is opposite the arc TE, therefore its value is also 40.
UYThe figure shows a right angle, then UY is equal to 90.
TYIf UY is equal 90, YE is equal to 90 too, because they are supplementary. If YE=90 and TE=40, you have:
TE+TY=90
40+TY=90
TY=90-40
TY=50
YLEYLE = YE+UE. The figure shows YE=90 and UE represents a semicircle (180). Thus,
YLE= 90+180=270
LEIf UE= 180 and UL=40, you have:
UE=UL+LE
180=40+LE
LE=180-40
LE=140
UETIf UE= 180 and TE=40, you have:
UET=UE+TE
UET=180+40
UET=220
