Answer:
Step-by-step explanation:
given is a system of linear equations in 3 variables as
This can be represented in matrix form as
AX=B Or
So solution set
X would be
|A|=-1(-1)+4(0)+2(-1)=--1
Cofactors of A are
-1 0 -1
-2 -1 -3
0 1 2
So inverse of A is
1 2 0
0 1 -1
1 3 -2
Solution set would be
x=12
y=-3
z=-5
and
are the experimental probabilities from the table.
Solution:
Total number of times spun the spinner = 60
Number of times getting 1 = 12
Number of times getting 2 = 17
Number of times getting 3 = 15
Number of times getting 4 = 16
<u>Experimental probabilities from the table:</u>
Probability of getting 1 =
Probability of getting 2 =
Probability of getting 3 =
Probability of getting 4 =
<u>To determine which are the experimental probabilities from the table:</u>
Option A: 15
This is not obtained above. So, it is not the experimental probability.
Option B:
This is obtained in the probability of getting 2.
So, it is the experimental probability.
Option C:
This is obtained in the probability of getting 3.
So, it is the experimental probability.
Option D:
This is not obtained above. So, it is not the experimental probability.
Option E:
This is not obtained above. So, it is not the experimental probability.
Hence and
are the experimental probabilities from the table.
