Answer: A probability of 1 means the event is certain to happen. A probably of zero means the event is certain not to happen.
9.4061,
9.07,
9.007,
9.4
Because ones are equal for all numbers, we are going to begin to compare from the second digits (tenths).
Greater :
9.4061 and 9.4.
Greatest is this group is 9.4061, then will go 9.4.
Smaller :
9.07 and 9.007
Greatest in this group is 9.07, and then will go 9.007.
So, from greatest to smallest : 9.4061 , 9.4 , 9.07 , 9.007.
From least to greatest :
9.007, 9.07, 9.4, 9.4061.
Answer:

Step-by-step explanation:
3 x 2 = 6
3 + 2 = 5
Answer:
C.
Step-by-step explanation:
The answer to your question would be C. No, the data values in each class could take on any value between the class limits, inclusive.
I hope it helps! Have a great day!

B = 67.58886795
All angles in triangle sum to 180 so find C with that
A + B + C = 180
C = 180 - A - B
C = 180 - 35.723697 - 67.58886795
C = 76.7°
