Answer:
3x - 5 = 10
Step-by-step explanation:
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.

Answer:
9
Step-by-step explanation:
Setup a proportion
= 
Cross multiply
40n = 360
Divide by 40
40n/40 = 360/40
n = 9
Answer:
13 minutes
Step-by-step explanation:
From 9:52 to 10:00 you have 8 minutes, and from 10:00 to 10:05 you have 5 minutes. Thus, the total time early is 13 minutes.
sinx=x-x^3/3!+x^5/5!-x^7/7!+x^9/9!
sinx/3x=1/3-x^2/18+x^4/360-x^6/15120+x^8/1088640
∫sinx /3x dx=x/3-x^3/54+x^5/1800-x^7/105840+x^9/9797760
