You can see if it's a square and looking to see if <em><u>all</u></em> the side lengths are the same size!
Answer:
a) 230300 ways
b) Check Explanation
Step-by-step explanation:
a) This is a combination problem,
We require how many ways 4 factories be placed among 50 states.
Mathematically, that is
⁵⁰C₄ ways = 230300 ways
b) If you have no idea which states will be chosen, what is the probability that all 4 factories will be located in the mid-Atlantic region.
This can be done in two ways
Method 1
The mid Atlantic region is one of 9 geographic divisions in the US
Probability of 1 factory being located in this geographic region = (1/9)
The probability of the 4 factories being in just this region = (probability of locating one factory in this region)⁴ = (1/9)⁴ = 0.0001524
Method 2
The mid Atlantic region contains only 3 out of 50 states. (New York, New Jersey, Pennsylvania)
Probability of 1 factory being located in one of the 3 stares = (3/50)
Probability of locating all four factories in one of the states in this region = (3/50)⁴ = 0.00001296.
Answer:
-11(-12)=132
Step-by-step explanation:
First divide 132 by negative 11 and get -12.
Then you connect -12 into the equation by using paraenthisies so its not a mess.
Last check your answer. -11 times -12 is equal to positive 132.
Answer:
It depends on how you write it.
- 130 8/9 -- one 8
- 130.88888888888... -- an infinite number of 8s
Step-by-step explanation:
The quotient 5890/45 has a value of 130 8/9. The fraction 8/9 is the repeating decimal 0.888888..., which has as many 8s as you want to write. It can be abbreviated to have just one 8 when written like this:
where the overbar indicates the digit repeats indefinitely.
The quotient can be written with as many 8s as you like.
