According to the World Health Organization (WHO), Body Mass Index (BMI) is a statistic that indicates the ratio of a person's weight to their body volume. The Center for Disease Control (CDC) uses the table to classify children from ages 2 to 20. Because BMI values change as children grow, the CDC uses percentiles rather than fixed values for BMI. Percentiles provide a basis of comparison for BMI over time. Weight status Percentile range
Underweight: Less than the 5th percentil
Healthy weight: 5th percentile to less than the 85th percentile
Overweight: 85th to less than the 95th percentile
Obese: Equal to or greater than the 95th percentile

Based on data from WHO, a representative sample of 15-year-old males could consist of the following 15 values.

18.1, 18.6, 15.9, 17.6, 21.9, 16.9, 20.8, 19.4, 21.3,
22.7, 19.0, 20.3, 19.8, 30.8, 24.3

85th percentile:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
