Question

ezra is learning to ride a unicycle. he practices for 30 minutes each day and keeps track of how many times he falls. this scatter - plot shows the number of falls during his first week of practice. it also shows the line of best fit. learning to ride a unicycle the equation for the line of best fit is y = - 2x + 25. according to the equation, which of these statements is true? ezra will probably fall about 7 times on the 11th day. ezra will probably fall about 1 time on the 12th day.

Explanation:

Step1: Identify the variables

The equation of the line of best - fit is $y=-2x + 25$, where $x$ is the day number and $y$ is the number of falls.

Step2: Calculate the number of falls for the 11th day

Substitute $x = 11$ into the equation $y=-2x + 25$.
$y=-2\times11 + 25=-22 + 25 = 3$.

Step3: Calculate the number of falls for the 12th day

Substitute $x = 12$ into the equation $y=-2x + 25$.
$y=-2\times12+25=-24 + 25 = 1$.

Answer:

Ezra will probably fall about 1 time on the 12th day.
