Since there are a total of 10 bottles, the probability of getting a certain one is based on the number of those bottles in the cooler.
The probability of getting a lemon-lime flavored drink is 4/10 or 40%.
The probability of getting a orange flavored drink is 3/10 or 30%
The probability of getting a fruitpunch flavored drink is also 3/10 or 30%.
If the question is asking what the probability is of choosing lemon-lime, fruit punch and fruit punch again in that order, you would multiply the probabilities together.
.4 * .3 * .3 = .036, so there’s a 3.6% chance of picking these exact 3 flavors happening again.
Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the mean of 110 and the standard deviation of 15, we have that:
These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.

Answer:
b. x= -6 or x=2
Step-by-step explanation:
|2x+ 4| = 8
The absolute value equation has 2 solutions, one positive and one negative
2x+4 = 8 2x+4 = -8
Subtract 4 from each side
2x+4-4 = 8-4 2x+4-4 = -8-4
2x = 4 2x = -12
2x/2 =4/2 2x/2 = -12/2
x =2 x = -6
