Two friends attribute their high math scores to their high level of effort and ability in math and their low spanish grades to their teacher's subjective grading and favoritism. in this situation these students are exhibiting bias.

In this situation these students are exhibiting the self serving bias.

Step-by-step explanation:

Two friends attribute their high math scores to their high level of effort and ability in math and their low Spanish grades to their teacher's subjective grading and favoritism.

In this situation these students are exhibiting the self serving bias.

The self serving bias is defined as a person's tendency to attribute positive events to their own character and hard work and they attribute negative events to external factors or any other excuse.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
