Empirical rule dictates that, in a Bell-shaped distribution, 95% of data lies within 2 standard deviation on either side of the mean.
Therefore,
Lower value = mean-2SD = 70-2*8 = 70-16 = 54
Upper value = mean+2SD = 70+2*8 = 70+16 = 86
Then, 95% of the data lies between $54 and 84. These values can also be taken as the true mean of the population considering 95% confidence when sample mean has been calculated. In this regard, 2SD can be regarded as the margin error.
The area of the large box is x^2 and the area of the small box is 3^2 which is 9. So the area of the leftover part is x^2-9 or (x-3)(x+3).

Answer:
y = 8x+0
Step-by-step explanation:
The slope is
m = (y2-y1)/(x2-x1)
= (-8-0)/(-1-0)
-8/-1
8
The y intercept is 0 since it goes through (0,)
The slope intercept form of the equation is
y = mx+b
y = 8x+0
Answer = A. Aella
Step-by-step explanation: Add 60, 25, and 95 degrees because that will equal 180 which is what the triangle equals.
