Answer:
1.) (2,1) is a solution
2.) (4,3) is NOT a solution
Step-by-step explanation:
1.) (2,1)
These are these mean (x,y)
2=x and 1=y
You want to substitute the numbers for the letters in the equation.
so.
2(2)+1=5
4+1=5
5=5, This statement is true so (2,1) is a solution.
2.) Same as above. 4=x and 3=y
4(4)-3(3)=10
16-9=10
7 Does Not Equal 10, Therefore, (4,3) is Not a solution to the equation.
Answer:
so what's the answer?
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
the frequency will change for each trial so a is wrong
b yea the probability should increase for either head or tail as the experiment progresses
c it will be impossible to get the frequency of head to equal the frequency of tails
d this is a 49/51 chance depending on what side did it flip on so while the frequency could increase the frequency could also decrease
the answer is B
I'm from your other question asking for help lmæo. and besides who flips that many coins
Answer:
the formula for finding cone volume is V=πr²× 1/3
Step-by-step explanation:
230=3.14×x²×1/3
we have to solve for X that is our radius
14.8
For this case we must find an expression equivalent to:
![\sqrt [7] {x} * \sqrt [7] {x} * \sqrt [7] {x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B7%5D%20%7Bx%7D%20%2A%20%5Csqrt%20%5B7%5D%20%7Bx%7D%20%2A%20%5Csqrt%20%5B7%5D%20%7Bx%7D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So, rewriting the given expression we have:
To multiply powers of the same base we put the same base and add the exponents:
