A bag contains 4 black and 3 pink balls. A ball is picked from the bag and is not replaced. A second ball is then picked from the bag.
The tree diagram below can be used to calculate various probabilities.
What is the probability of picking one
ball of each colour?
A
4/49
B
24/42
C
1/2
D
12/42
Answer:
1/2
Step-by-step explanation:
There are 4 possibilities:
First ball Second ball
1. Black Pink
2. Black Black
3. Pink Pink
4. Pink Black
The first and the forth options are the the probabilities that there is picked one ball for each color. (2 possibilities )
The second and the third options are the probabilities that there ate picked 2 balls of same colour.
(2 possibilities)
There are 4 possibilities in total. So the probability is 2/4=1/2
find the endpoint S given R(5,1) and midpoint M(1,4)
Given:
Point R: (5, 1)
Midpoint M: (1, 4)
Since it's been mentioned that point M is a midpoint. Finding S, the graph should look like this:
Let's determine the translation from point M to R, because the opposite of it will be the translation to get point S.
From Point M to R:
[tex]\text{ }\Delta x\text{ = 5 - 1 = 4 (4 units to the right)}[/tex][tex]\Delta y\text{ = 1 - 4 = -3 (3 units downward)}[/tex]Therefore, getting to the endpoint S, it will have 4 units to the left and 3 units upward.
We get,

After a translation, the figure becomes the red one, with the following points:

Answer:
m∠1 = 80°
m∠2 = 80°
m∠3 = 100°
Step-by-step explanation:
Same-side Exterior Angles Theorem
When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary (sum to 180°).
Therefore:
⇒ m∠1 + 100° = 180°
⇒ m∠1 + 100° - 100° = 180° - 100°
⇒ m∠1 = 80°
Corresponding Angles Postulate
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
Therefore:
⇒ m∠2 = m∠1 = 80°
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ m∠3 = 100°
after how many hours will the two trucks be 558 miles apart?

What is Vertically opposite angle?
At first we need to understood what is angle
Angle
When two straight lines intersect, an angle is formed. The point of intersection is called the vertex of the angle and the lines are called the arms of the angle.
Vertically opposite angle
The angle formed by two intersecting straight lines and are opposite to one another at a specific vertex is called vertically opposite angle.
Vertically opposite angles are equal.
Here,
∠b = 126° [Vertically Opposite Angle]
∠c = 180° - 126° [Angle on a straight line]
= 54°

Which linear inequality is represented by the graph?
The linear inequality that is represented by the graph is y ≤ x/3 - 4. The correct option is the second option y ≤ x/3 - 4
Graph of Linear inequalitiesFrom the question, we are to determine the linear inequality that is represented by the graph
First, we will determine two points on the line
The line in the graph passes through (0, -4) and (3, -3)
Using the equation,
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
(y - -4)/(x - 0) = (-3 - (-4))/(3 - 0)
(y + 4)/x = (-3 + 4)/3
(y + 4)/x = 1/3
y + 4 = 1/3x
y = 1/3x - 4
y = x/3 - 4
This is the equation of the line
In the given graph, the line is a solid line and the solution of the inequality is below the line

Answer:
(d) The triangles are similar, because each has angles that measure 36°, 62°, and 82°.
Step-by-step explanation:
Given triangle A has angles 36° and 82°, and a figure showing angles related to triangle B, you want to know if the triangles are similar.
SimilarityThe triangles will be similar if the angles of one are congruent to the angles of the other. Between the two triangles, we are given 3 different angle values, so we need to find at least two additional angle values in order to determine if the triangles are similar.
Angle sum theoremThe sum of angles in a triangle is 180°, so the third angle of triangle A will be ...
angle = 180° -36° -82° = 62°
Exterior angleThe exterior angle of triangle B, given as 144°, is the sum of the remote interior angles:
144° = 62° +angle
82° = angle
ComparisonNow, we have the angles of triangle A as 36°, 62°, and 82°. Two of the angles of triangle B are known to be 62° and 82°, matching those of triangle A.
The triangles are similar, because each has angles that measure 36°, 62°, and 82°.

Noted that the Diagonals of a parallelogram bisect each other. Here in PQSR, it does bisect PT =ST and QT = TR). Hence, PQSR is a parallelogram.
Note that IGHJ is a parallelogram. This is because the opposite sides of a parallelogram are congruent. Here, H = I and G = J. Hence, IGHJ is a parallelogram.
It is correct to state that CABD is a parallelogram because of the alternative interior angles ACB = CBD and ABC = BCD.
VWYX is NOT a parallelogram. The rule states that if opposites sides are congruent then the quadrilateral is a parallelogram. In this case, clearly, line VW ≠ XY and VX ≠ WY.
What is a parallelogram?A parallelogram (which could be a rhombus, rectangle, or square) is a quadrilateral with congruent and parallel opposing sides.

Which of the following equations represents a line that passes through thepoints (-3, -14) and (0, –2)?Alg 1
Problem
Which of the following equations represents a line that passes through the
points (-3, -14) and (0, –2)?
Solution
For this case we want to create an equation with this general form:
y= mx+b
We can calculate the slope with this operation:
[tex]m=\frac{-2+14}{0+3}=4[/tex]And the intercept can be founded with the second point:
-2= 4(0)+b
b= -2
And the equation would be:
y= 4x -2
If we analyze the second option given we can see that we can write like this:
y-6 = 4(x-2)
y-6= 4x-8
y-6+8 =4x
y+2= 4x
y= 4x-2
So then the best option would be:
II. y-6 = 4(x-2)
Draw triangle QRS with altitude RT. If m/RSQ = 43°, then find the m/TRS.
Do not include a degrees symbol on your answer.
The measure of angle TRS would be of 37º.
What is the measure of angle TRS?The vertices of the triangle can be attributed freely, hence we attribute as is in the drawing.
The altitude RT bisects the triangle forming a right angle, with R and T, hence the internal angles of the triangle TRS are as follows:
43º -> as given in the problem.90º -> due to the bisection.x. -> Angle TSR, which is the missing measure that we need to find to solve this problem.The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of the missing angle TSR can be found as follows:
43 + 90 + x = 180

x = 180 - 133
x = 47º -> m<TSR = 47º.

Answer:
4590
Step-by-step explanation:
When rounding to the nearest ten we use these following rules.
We round the number up to the nearest ten if the last digit in the number is 5,6,7,8 or 9.
We round the number down to the nearest ten if the last digit in the number is 1,2,3, or 4.
If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
117 divided by 18. Show the answer as a fraction in lowest terms
Answer:
Im unsure what your asking but the answer is 6 1/2 in fraction form and 6.5 in decimal form :/
Step-by-step explanation:
math
When 117 is divided by 18 we get 117/18 in fraction form.
To divide 117 by 18, we perform long division.
We start with the first digit of the dividend (1) and divide it by the divisor (18).
Since 18 is larger than 1, the quotient for this step is 0.
We then bring down the next digit (1) and place it next to the previous result.
Again, since 18 is larger than 11, the quotient for this step is 0.
Therefore, the result of dividing 117 by 18 is 0 with a remainder of 117.
In fraction form, this can be expressed as 117/18.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left-hand side = right-hand side) in every mathematical equation.So, the relationship between the dollar cost of the dinner, C, and the number of guests, g, is represented by the equation C = 410 + 22g.
We can see that the equation we have been given is in the form of a slope-intercept equation, y = MX + b, where m denotes the slope of the line and b denotes the y-intercept or beginning value.We can observe that the slope and C-intercept of the following equation are 22 and 410, respectively.The C-intercept tells us that when there are 0 guests in the banquet, the cost would be $450.When we have 50 guests at the banquet the cost would be:
