Answer:
11/18
Step-by-step explanation:
The desired probability is the sum of ...
... (probability of choosing a coin) × (p(heads) on that coin)
Since the coins are chosen at random, we assume the probability of choosing a given coin is 1/3. Then ...
... p(heads) = (1/3)·(1/2) + (1/3)·1 + (1/3)·(1/3) = 1/6 + 1/3 + 1/9 = (3 +6 + 2)/18
... p(heads) = 11/18
Answer:
let the no.s be : x, x+1, x+2
then,
=> x + x+1 + x+2 = 183
=> 3x + 3 = 183
=> 3x = 183 - 3
=> x = 180/3
=> x = 60
therefore, the whole no.s are 60, 61, and 62
If we write y=f(x)=(x-h)²+k, then y-k=(x-h)². This is vertex form where the vertex is (h,k)=(3,3) so h and k are both 3. We can see this if we put x=3 in the shifted function. This is a minimum point for the function because for every other x f(x) is greater then 3. The minimum point is the vertex.

the answer is A ...........
Answer:
x = -4
Step-by-step explanation:
Divide both sides by -2.
x= - 8/2
Simplify - 8/2 to -4.
