Answer:
Step-by-step explanation:
So what is the probability of the selecting the first coin? There are total of 4 different coins, so the probability of getting a dime is 1 out of 4, then he replace it, then again the probability stays the same, he still has 1 out 4 chance of getting a dime. So then it's just 1/4*1/4=1/16 :)
Answer:
(1,3)
Step-by-step explanation:
The given function is
Factor 2 from the first two terms
Add and subtract the square of half the coefficient of x.
Let us create perfect square trinomial
This implies that:
Therefore the vertex is (1,3).
We got this by comparing to
<h3>
Answer:</h3>
y = -3x +2
<h3>
Step-by-step explanation:</h3>
The y-intercept is at +2, so that is the value of the added constant (b).
The line goes down 3 units for each unit to the right, so the slope (m) is ...
... m = ∆y/∆x = -3/1 = -3
Then in the form ...
... y = mx + b
with m=-3 and b=2, your line's equation is ...
... y = -3x +2
