Probability (P) is basically outcome, and chance. What are the chances of grabbing a red or blue marble?
Well, there IS a more complicated way to solve this, but let's go the easy way.
You calculate probability with this equation:
Probability=Events/Number of outcomes
If you want to find the probability of grabbing a red or blue marble, you first have to find all possible outcomes by adding ALL numbers together. 6+6+4=16. Next, find how many events you have. Well, you want to find red or blue. Add the number of red and blue marbles together. 6+4=10, so your equation now looks like: Probability=10/16
Now, just simplify.
10/16 can be divided evenly by 2 on both sides, so just do that, and you get:
5/8
You have a 5/8 chance, or a 0.625 chance of drawing a red or blue marble.
Answer:
d ≈ 135.1 m
Step-by-step explanation:
The circumference formula is:
In order to solve this, just substitute 43 cm into C, to get:
Divide 43 by 2 times pi to find the radius:
Then in order to find the diameter, double the number of the radius:
×
d ≈ 135.1 m
Step-by-step explanation:
Answer: Option C - Construction Y because point E is the circumcentre of triangle LMN.
Point E is the best location for the warehouse as it is exactly equidistant from the three stores at L, M and N.
Step-by-step explanation:
Before solving an algebra problem, it sometimes helps to get a geometric picture of what's happening. Geometry says that three points determine a circle - in other words, given three points that are not
all on the same line, there is exactly one circle which passes through all 3. Finding the point equidistant from the 3 points is the same thing as finding the center of the circle that passes through all of them (since all points on a circle are equidistant from the center).
Our points are L, M and N. Draw the lines LM, LN and MN to form a triangle. Now construct the perpendicular bisectors of any two of the lines, and their intersection, point E, will be the center of this circle.
As shown in the Construction Y because E is the circumcentre of triangle LMN.
This is the best location for the warehouse as it is exactly equidistant from the three stores at L, M and N.
