Answer:
approx. 154 or 49pi
Step-by-step explanation:
The answer is C.3 I did this one on my credit recovery
Slope Intercept Form Equation: mx + b = y
Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.
Μ = 268 days, the population mean
σ = 9 days, the population standard deviation
For the random variable x = 272 days, the z-score is
z = (x-μ)/σ
= (272 - 268)/9
= 0.4444
From z-tables, obtain
P(z <= 0.6716) = 0.6716 = 67.2%
Answer: 67.2%
