A bowl has 3 red beads and 7 blue beads. Two beads are selected at random one at a time. First a red bead is drawn and placed on a table. Next a blue bead is drawn.
What is the probability of this event?
Drag and drop the answers into the boxes to complete the sentences.
Answers
The probability that first a red bead is drawn and next a blue bead is drawn is 7/30,and both events are dependent
How to determine the probability?The distribution of the beads are:
Red = 3
Blue = 7
Total = 10
The probability of selecting the red bead first is:
P(Red) = 3/10
When the red bead is selected, the number of beads becomes 9
So, the probability of selecting a blue bead is
P(Blue) = 7/9
The probability of the event is then calculated using:
P = 3/10 * 7/9
Evaluate
P = 7/30
Hence, the probability of the event is 7/30

Find the measure of angle x in the figure below:
A) 35
B) 47
C) 51
D) 62
Answers
Answer:
The value of y = 62°
and x = 50°
Step-by-step explanation:
=> 57° + y + 61° = 180°
=> 118° + y = 180°
=> y = 180° - 118
=> y = 62°
Now ,
x° + y° + 67° = 180° { sum of angles of a triangle is 180° }
=> x° + 62° + 68° = 180°
=> x + 130° = 180°
=> x = 180° - 130°
=> x = 50°

Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer
Answers
Answer:
Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2
7x-8=5x-2
+8 +8

7x=5x+6
-5x -5x

given two points: (−3, −8) and (10, −8)
As the y coordinates are same.
use the method:
|x2| + |x1| where (x1, y1), (x2, y2)
Solve:
|10| + |-3|
10 + 3

Answer:
10 units
Step-by-step explanation:
[tex](x_1,y_1)=(-3,-8)[/tex]
[tex](x_2,y_2)=(10,-8)[/tex]
We are supposed to find the length of the line segment with endpoints (−3,8) and (7, 8)
We will use distance formula : [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute the values :
[tex]d=\sqrt{(10+3)^2+(8-8)^2}[/tex]
[tex]d=\sqrt{100}[/tex]
[tex]d=10[/tex]
Hence the length of the line segment with endpoints (−3,8) and (7, 8) is 10 units
