Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
So a²+b²=c²
8²+15²=c²
64+225=c²
289=c²
±17=c
So c=17 or c=-17
It would be heads 3 and 1/3 of the time and tails 6 and 2/3 coming to an outcome of 10
Answer:
Step-by-step explanation:
So this is multiplication
24.5 times 20 in dollars is $4.90 if we round it than it will be 5 dollars
