Answer:
0.344
Step-by-step explanation:
There are 20C10 = 184,756 ways to choose 10 problems at random from a list of 20.
There are 10C5 = 252 ways to choose 5 of the 10 algebra problems, and the same number of ways to choose 5 of the 10 geometry problems. Then there are 252² = 63,504 ways to choose 5 problems each of algebra and geometry.
The probability of choosing 5 problems in each category is ...
63504/184756 ≈ 0.344
It’s actually true!

The 4 arrows above the number line represents the distance between 2 and -2 which is 4!
The problem here takes a brilliant mind to answer this. This problem can easily be answered using programming because we can not then and there push all the possibilities using paper and pen.
The answer is 3816547290.
Trying all the possibilities starting form 1000000080 (we are sure that the last number should be 0). Then traversing that number until 9999999990. Each traverse, check the number if its divisible to n, so on and so forth.
The answer is b.
The length of the rectangle is 3w-150.
The width is w.
To get area you multiply length and width so w(3w-150)=70,200. The numbers in parentheses is the length.
You use distributive property and distribute the w to get 3w^2-150w=70,200.
You can simplify the equation by dividing both sides by 3 to get w^2-50w=23,400.
Then you get all the numbers on the left side of the equation by subtracting 23,400 to get w^2-50w-23,400=0.
Now that the equation equals zero, you can factor it to get (w+130)(w-180)=0.
Then you find the values for x with each factor which are x=-130 or x=180.
We would use the positive value for x because it is area.
You substitute 180 for x in 3w-150 and you would get 390.
