Let’s count it.
I’m assuming that you have a regular deck of cards and that means 13 hearts and 13 kings.
You can pick any card of 52 with equal probability 1/52 for each.
So there are 52 opportunities of 1/52 probability to take any card from deck.
But you are looking only for 13 of hearts and for 13 of kings. That means your chance is (13 + 13) / 52 = 1/2 :)
Answer:
Step-by-step explanation:
C
Your table of values is so difficult to read that many of us helpers would just skip your post.
<span>x f(x) -6 2.5 -2 2.5 0 2 2 0 3 5 5 2.5 1 0.5</span> could be put into far clearer format as follows:
x f(x)
-- -----
-6 2.5
-2 2.5
and so on. Please fix it.
The "average rate of change" formula is
f(x2) - f(x1)
av r of c = ---------------
x2-x1
so if you go from (-6, 2.5) to (2.5, 10.5), the av r of c would be
10.5 - 2.5 9 18
------------------ = -------- = -----
2.5-(-6) 8.5 17
This may or may not be your final answer. Again, please put your data table into readable form and then find the av r of c over the interval [-2,3].
Y=5x
Explanation:
You would take two points and use the slope formula
Y2-y1/x2-x1
So I took the points (0,0) and (1,5)
5-0/1-0
5/1
5= the slope
So now we know y=5x+b and since it shows us on the graph where the line crosses the y axis we know the y intercept will be zero because it crosses at 0. When the y-intercept is 0 we don’t even need to list it.
Make a end of each equation
Find the point where the two lines connect.
Easy day! I hope this 100% helps!
