Answer:
6.8, 16.6, 26.4, 36.2
Step-by-step explanation:
Let's write the sequence, d is the common difference:
- 3, - 3 + d, - 3 + 2d, -3 + 3d, - 3 + 4d, 46
Therefore 46 = -3 + 5d
5d = 49
d = 49/5 = 9.8
So the first arithmetic mean is -3 + 9.8 = 6.8. and the second is -3 + 2(9.8) = 16.6...
They are:
6.8, 16.6, 26.4, 36.2.
The answer is 85 times 7. Since the banana was 5 less then the split, the split is 5 more which is 85 calories but then it says it is also 1/7 of the whole split. So you simply multiply 85 and 7 because 85 was only 1/7 of the total banana split

Answer:
median = 2.8 m
Step-by-step explanation:
the median is the middle value of the data set in ascending order.
If there is no exact middle value then it is the average of the values either side of the middle.
the stem- leaf diagram shows the data in ascending order from 1.6 to 4.5
there are 10 data values so no exact middle value.
the median lies between 2.7 and 2.9
median = (2.7 + 2.9) ÷ 2 = 5.6 ÷ 2 = 2.8 m
