F=5+2=7 bye I want points
What we know:
1. y = 2x because angles facing each other are equal to each other
2. A straight line means 180 degrees.
Steps:
y + (x + y + 5) = 180
2y + x = 175
2 (2x) + x = 175
5x = 175
x = 35
y = 2 (35) = 70
Answer:
no they are not because 11, 14 is the only one that has a vertices
Step-by-step explanation:
Answer:
0.0082 = 0.82% probability that he will pass
Step-by-step explanation:
For each question, there are only two possible outcomes. Either the students guesses the correct answer, or he guesses the wrong answer. The probability of guessing the correct answer for a question is independent of other questions. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
.
If the student makes knowledgeable guesses, what is the probability that he will pass?
He needs to guess at least 9 answers correctly. So
0.0082 = 0.82% probability that he will pass
Here we go ~
1. A circle can be named by their Centre, so here in the diagram it's :
2. Name 4 radii :
Radii are the line segments that joins the centre and boundary of circle.
They are :
3. 2 Major arcs :
considering two points on a circle, and joining them forms a curve ( you can say part of circumference )
When we consider two points two arcs are formed and the arc with more length is known as Major Arc
That is :
- Major arc ECF
- Major arc BEC
4. A Semicircle :
Semicircle is special arc which is formed when two arcs formed by the points are equals to one another... it's also half the Perimeter of circle.
that is :
5. 3 minor arcs :
The arc formed by two points having lesser length is known as minor arc.
that is :
6. 3 Central angles :
Central angles are angles formed by arcs on centre of the circle ~
that is :
- Angle FAB
- Angle BAC
- Angle GAB
7. A diameter :
Diameter is a chord that passes through centre of the circle.
8. Congruent Angles :
In the given figure, there are two equal/congruent angles that are ~
9. Adjacent arcs :
The arcs that have one common end point are known as Adjacent arcs ~
that are :
