Answer:
A. √10
Step-by-step explanation:
A rational number can be written as the ratio of two integers
A. √10
This cannot be simplified into the ratio of two integers, Square roots that cannot be simplified are irrational
B. -√81
- 9
-9/1 which is the ratio of two integers so it is rational
c. 5/4
This is the ratio of two integers so it is rational
d. 9.12
912/100
This is the ratio of two integers so it is rational
Y 20? ....................... .......................... ........................
7+d=19 is the answer
subtract 7 from each side d=19-7
d=12
Answer:
it is underfined because if you look closely there is no slope in the graph
Start by doing the binomial expansion of (x+y)^6 where x represents success. This is
(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)
We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is
20/64 = .3125 which is 31.25%
