Total Marbles = 8 + 6 + 12 + 10 = 36
Probability the marble is blue = 8/36
Inverse this to get the probability of the marble not being blue
Probability of the marble not being blue = 28/36 = 7/9
Answer:
Graph A
Step-by-step explanation:
I had this question in my class and got it right with answer A :')
Answer: we can get the sequence of reasons with help of below explanation.
Step-by-step explanation:
Here It is given that, line segment BD is the perpendicular bisector of line segment AC. ( shown in below diagram)
By joining points B with A and B with C ( Construction)
We get two triangles ABD and CBD.
We have to prove that : Δ ABD ≅ Δ CBD
Statement Reason
1. AD ≅ DC 1. By the property of segment bisector
2. ∠BDA ≅ ∠ BDC 2. Right angles
3. BD ≅ BD 3. Reflexive
4. Δ ABD ≅ Δ CBD 4. By SAS postulate of congruence
Slope is 3/4
