The weights of tennis balls are normally distributed, with the mean being 5.15 ounces and the standard deviation being 0.10. wha
Llana [10]

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.

Solve the absolute value equation. 20x - 19 = 0
Phantasy [73]

To solve this absolute value equation, we can use find the solutions as follows taking into account the definition of absolute value, then, we have:

|20x-19|=0\Rightarrow20x-19=0,or-(20x-19)=0

Now, we can solve both equations to find the solution(s):

First case:

20x-19=0\Rightarrow20x=19\Rightarrow x=\frac{19}{20}

Second case:

-(20x-19)=0\Rightarrow-20x+19=0\Rightarrow-20x=-19\Rightarrow x=-\frac{19}{-20}\Rightarrow x=\frac{19}{20}

Then, both solutions are the same, because of the absolute rule (this is the point when y = 0, that is the x-intercept for this function.)

Therefore, the solution set is {19/20}.
