Answer:
Part A: The mean of the data is 8.
Part B: The Mean Absolute Deviation is 0
Step-by-step explanation:
Part A: For the mean, you add all the numbers up and then divide your answer by how many numbers you have. So You would do 64 divided by 8 and it gives you 8.
B: Since the Mean is 8, You would subtract each number by 8, but add. (I'm Going To show it under here)
|8 - 8| + |9 - 8| + |9 - 8| + |7 - 8| + |8 - 8| + |6 - 8 | + |9 - 8| + |8-8| .
0 1 1 -1 0 -2 1 0
Add them up and it should give you 0.
Answer:

Answer:
c
Step-by-step explanation:
Jessica planted a rosebush in her garden. The rosebush has a height of 30 cm. Each month the rosebush increases by 6 cm. Which equation can be used to determine the height of the plant in centimetres, y, after x months?
the rate of increase of the bush every month is 6 cm
Rate of increase of the bush in x months = 6x
because the bush increases every month, 6x would be added to 30cm
y = 6x + 30
If the bush decreased at a rate of 6cm every month, the equation would be y = 30 - 6x
