The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.

Answer:
Mode = 2.60
Step-by-step explanation:
In statistics, mode means the number that occurs the most number of times.
Let's see the set of numbers:
{2.94, 2.60, 3.30, 2.53, 2.16, 4.65, 5.40, 6.71, 5.76, 3.67, 2.19, 2.60}
There are 12 numbers here. <em>Which number occurs more often? Most?</em>
<em />
Looking at the list carefully, we see that 2.60 occurs twice and all other numbers occur single time. Hence the mode = 2.60
