Answer:
The reasonable prediction for successful rolls is 4.
Step-by-step explanation:
Assuming the rolling cube is a fair 6 sided cube, so the probability of success of one roll is given as
The total success is given as
For 24 rolls it is given as
So the reasonable prediction for successful rolls is 4.
1 = 6
5=8
6=75%?
7=21?
8=21
9=400
10=100
11=40
These are all the one I got the ones with ? At the end I’m not sure about
Step 1. Solve both inequalities for
:
Step 2. To check a point in the solution of the given system of inequalities, look for the intercepts of the lines
and
:
(1)
(2)
Replace (1) in (2):
Solve for
:
(3)
Replace (3) in (1):
We can conclude that the point (-2,3) is in the solution of the system if <span>
inequalities</span>
; also any point inside the dark shaded area of the graph of the system of inequalities is also a solution of the system.
We have that
2x²=450 ----------> x²=450/2----------> x=√225
x1=+15
x2=-15
<span>a reasonable length measurement should be positive
</span>therefore
the answer is
<span>The solutions are -15 and 15, but only 15 is a reasonable side length.</span>
