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
Answer:
x=1
Step-by-step explanation:
(7x-1)+(2x-1)=7
7x+2x-1-1=7
7x+2x=7+1+1
9x=9
9x/9 = 9/9
x=1
Answer:
The answer to the question provided is letter D.
Answer:
0.25p+20
Step-by-step explanation:
Since there is a set up fee of $20 then you would have to add it to the value of what 0.25p will be. Since p represents every square foot of the walls and you would multiply p by 0.25 every square foot is $0.25 then 0.25p+20 would accurately represent the problem
