Hope this helps if so please brainliest :)
and also sorry for the wait
Step-by-step explanation:
I believe B
Because on the x axis it reaches 600 on eight and the last number that was recorded was 450 so 600-450=150
Allison ran 3/8 km (0.375 km) in 3 minutes.
Set up a proportion to find how long it takes for her to run 1 km
Cross multiply to get:
Solve:
x = 8 minutes
The problem uses the concept of Combination where there are number of members chosen from a group and there order is not important. Thus, the expression that would best describe the given above is 30C6 which means the combination of 30 taken 6. The numerical value for this is 593775.
The answer is 
.
Solution:
Use algebraic identity: 
For example: 
Given expression 
and 
.
To multiply these equations.
Combine like terms together.
Hence the answer is .
you can imagine this as a venn diagram. the "or" event would consist of everything in both sides and the middle of the venn diagram because you can choose form either event x <u>or</u> event y.
the "and" event would consist of everything in the middle of the venn diagram because you choice must be a part of both event x <u>and</u> event y.
the complement of an event is just everything that is not included in the event. for example, in a coin flip, the complement of heads is tails. in a dice roll, the complement of {1,2} is {3,4,5,6}
so if you come across these just think "either or" or "both and." and remember that the complement is everything excluding what is listed.
i apologize if this does not help, im not that great at explaining things
