Answer:
m= -2
Step-by-step explanation:
Use the slope formula to find the slope m
.
The averge rate for time is 1.5 and the averge rate for height is 148
The total values in the dataset is 24 values
From the given histogram, to get the number of values in the dataset, we will have to trace each bar to the y-axis and then take the sum.
- For the black bar, the total values of the dataset will be 11 + 2 = 13
- For the white bar, the value of the data st will be 3
- For the grey bar, the total values of the dataset will be 1 + 2 = 3
- For the ask bar, the total values of the dataset will be 2 + 3 = 5
The total values of the dataset = 13 + 3 + 3 + 5
The total values of the dataset = 24 values
Hence the total values in the dataset is 24 values
