Answer:
The discrete probability distribution satisfies all the features,
Step-by-step explanation:
We are given the following discrete probability distribution:
Outcome: 0 1 2 3 4 5 6
Probability: 0.0570 0.2281 0.3462 0.2547 0.0955 0.0173 0.0012
Property of discrete probability distribution:


Verification:
1. As observed all the probabilities are between 0 and 1.
2.

Thus, the given discrete probability distribution is a valid distribution.
Answer:
3*2+8
Step-by-step explanation:
Find out the determinant
we have
2x-y=4
3x+y=1
so
D=(2)(1)-(-1)(3)
D=2+3
D=5
therefore
<h2>the answer is the second option</h2><h2>Verify</h2>
solution (1,-2)
equation 1 -------> 2(1)-(-2)=4 -------> 4=4 is true -----> is ok
equation 2 ------> 3(1)-2=1 -----> 1=1 ----> is true -----> is ok
Answer:
(3,16)
Step-by-step explanation:
Factor the equation to find out that the roots are 7 and -1. The vertex's x will be in the center of these two points, so the center point between 7 and -1 is 3. Continue to substitute the x in the equation with 3 to get the other coordinate for vertex.
