The correct option is B.
Thus, 68% percentage of the balls weigh within one standard deviation of the mean.
<h3>What is the empirical formula rule?</h3>
The Empirical Rule indicates that 99.7% of data that are observed to have a normal distribution fall within 3 standard deviations of the mean. According to this formula, 68 percent of the data are within one standard deviation, 95 percent are within two standard deviations, and 99.7 percent are within three standard deviations of the mean.
<h3>According to the empirical formula rule:</h3>
Because approximately 68% of the data falls within a standard deviation of the mean, according to the empirical rule, 68% of the balls' weights fall within that range.

B. 68%
C. 95%
D. 99.7%
Answer:
D) The y-intercept represents the jump height at the minimum bicycle weight.
Step-by-step explanation:
Since the bicycle weight starts at 0, which everyone knows means "minimum", and the jump height marks at 11.5 when you look at the y-axis, it clearly means that that is the jump height at the lowest possible bicycle weight.
The answer choice which describes the function is; Choice B; neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.
<h3>What is rotational symmetry?</h3>
Rotational symmetry, otherwise termed radial symmetry, is the characteristic of a shape when it looks the same after some rotation by a partial turn. On this note, since the function represents a quartic graph, it follows that the function has neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.
Therefore, the function f(x) = −4x⁴ + 3x³ − 2x² − x + 5 is neither symmetry about the y-axis nor has order 2 rotational symmetry about the origin.

Factor 5 5 out of 25 x 2 25x2.
5 ( 5 x 2 ) − 20 x y + 180 y 2 5(5x2)-20xy+180y2
Factor 5 5 out of − 20 x y -20xy.
5 ( 5 x 2 ) + 5 ( − 4 x y ) + 180 y 2 5(5x2)+5(-4xy)+180y2
Factor 5 5 out of 180 y 2 180y2. 5 ( 5 x 2 ) + 5 ( − 4 x y ) + 5 ( 36 y 2 ) 5(5x2)+5(-4xy)+5(36y2)
Factor 5 5 out of 5 ( 5 x 2 ) + 5 ( − 4 x y ) 5(5x2)+5(-4xy). 5 ( 5 x 2 − 4 x y ) + 5 ( 36 y 2 ) 5(5x2-4xy)+5(36y2)
Factor 5 5 out of 5 ( 5 x 2 − 4 x y ) + 5 ( 36 y 2 ) 5(5x2-4xy)+5(36y2). 5 ( 5 x 2 − 4 x y + 36 y 2 )
