Answer:

9857÷ (22÷7) = 3136.318ft

Circumference divided by pi = diameter

9857÷ (22÷7) = 3136.318ft

Julli [10]

Answer:

2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional.

Step-by-step explanation:

Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line.

Number 3 does not go through the origin, so number 3 is also not proportional.

Number 5 is proportional since when you divide y by x, it is always 7.

Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.

Help me with this question this was supposed to be due yesterday!
Inessa05 [86]

Answer: Both the mean and median decreased.

Step-by-step explanation:

The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

[I do apologize in advance if it's wrong, and next time try submitting work on time :)) Hope I helped!]
