we know that
1) Lily swims a
-meter race
2) She swims the first half in
seconds
3) She swims the second half in
seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half

therefore
<u>the answer is</u>

Step-by-step explanation:
slope intercept form is in: y = mx + b
12y = -8x + 48
y = (-8x+48)/12
y = -2/3x+4

Therefore, we expect the sample mean to be different from the population mean.
