Answer:
a) 37th percentile: 33 years
b) 72nd percentile: 62 years
Step-by-step explanation:
The kth percentile divides the data into two: on the one hand the lowest k% of the data, and on the other the (1-k)% higher of the data.
For the list provided, the 37th percentile falls to the age of 33. This means that 37% of the data are for ages under 33 years.
The 72nd percentile falls at the age of 62 (72% of the ages fall below 62 years).

Answer:
Inversely proportion states that a relationship between two variables in which the product is a constant.
If one of the variable increases, then the other decreases in proportion so that the product is unchanged.
If y is inversely proportional to x, then the equation is of the form
; where k is the constant proportionality.
As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,
Let x represents the speed of car and y represents the time taken.
From the given condition:

Then by definition of inversely proportional;
[Since,
]
Here, k represents the distance(i.e constant) = 100 miles.
therefore, the equation becomes now;
or
xy = 100
The following graph for the above equation as shown below :

Answer:
1 mile
Step-by-step explanation:
5 × (1/5 mi) = 5/5 mi = 1 mi
The students ran 1 mile in all.
Answer:
X/3 X is unknown, so it would be this until you figure out X
