What is the median age for the following data set representing the ages of students requesting tickets for a summer band concert? Explain your reasoning. 13 14 15 15 16 16 17 18 18
Answer:
16 is the median
Step-by-step explanation:
By definition, the median is the mid value or the middle number of a given data set
Firstly, we have to arrange the numbers in ascending or descending order
What we have as the count of the numbers here is 9
So the middle number is the 5th term counting from either sides
As we can see, the fifth term here is the number 16

Time Remaining56:19m:s When I have walked 20 % of the way to school, I have 1200 metres more to walk than when I have 20 % of the walk remaining. How far, in metres, is it from my home to my school?
Answer:
x = Total distance from your home to school = 1,500 meters
Step-by-step explanation:
Let
x = Total distance from your home to school
When you walked 20% of the way to school, you still have 1200 meters more to walk
Walked distance = 20% of x
= 20/100 * x
= 0.2 * x
= 0.2x
Total distance - walked distance = 1200 meters
x - 0.2x = 1200
0.8x = 1200
x = 1200 / 0.8
x = 1,500 meters
x = Total distance from your home to school = 1,500 meters

A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of 59
A degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only

, which means that for an increase of 1 degree Fahrenheit, the increase is 5/9

/

of 1 degree Celsius. Therefore, statement I is true.
This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 9/5
9
/
5
degrees Fahrenheit. Since 95

= 1.8, statement II is true.
On the other hand, statement III is not true, since a temperature increase of 9/5
9
/

degrees Fahrenheit, not 5/9
5

degree Fahrenheit, is equal to a temperature increase of 1 degree Celsius.
The final answer is D.

Another question how fast is Andrew traveling?
Answer:
DannyStep-by-step explanation:
Danny's speed is given:
15 mphAndrew's speed is found from the table.
Since its the direct relationship, we find it using one pair of values:
Speed = miles/times = 21.75/1.5 = 14.5 mphDanny is faster as 15 mph > 14.5 mph
Speed =Distance/Time
Here speed is equal to slope of box
m=y/xm=29/2m=14.5mphDanny is faster as his one is 15mph

The sum of the numbers 13 + 13 + 13 is 39.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given expression is,
13 + 13 + 13
Here 13 is added to itself three times.
When 13 added to 13, we get 13 + 13 = 26
Again if we add the number 13 to 26, we get 13 + 26 = 39
13 + 13 + 13
= 26 + 13
= 39
This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.
Hence the number 13 added to itself three times gives 39.
