What is the median of the data below?<br><br> 45, 19, 23, 67, 28, 35, 46, 21, 58, 60, 23, 51
VLD [36.1K]
To find the median, you will need to list the data from least to greatest and find the middle number.

19, 21, 23, 23, 28, 35, 45, 46, 51, 58, 60, 67

Cross out a number on both sides until you reach the middle number. In this case, we are left with 2 numbers that are in the middle since there is an even amount of numbers. 

When you reach the time where you have two middle numbers, we have to find the average of those two numbers. Our two middle numbers are 35 and 45. Since we have to find the average of those two numbers, we can add them. (35 + 45 = 80). Now, since we have two middle numbers, we have to divide them by 2. 
80 \div 2 = 40

Answer: \fbox {Median = 40}

Tim tiene 39 pares de audífonos y 13 reproductores de música. Tim quiere vender todos los audífonos y los reproductores de músic
Lena [83]

Answer: 13 packages.

Step-by-step explanation:

This can be translated to:

Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?

To solve this we must find the largest common factor between 39 and 13.

to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.

13/1 =13 and 39/13 = 3

So 13 is the largest common factor.

This means that we can make 13 packages, each with:

39/13= 3 headphones

13/13 = 1 music players

If a circle has a radius of 9 and a sector defined by a 254 degree arc, what is the area of the sector
myrzilka [38]
The answer is 179.451 or 1143π/20.

The arc is 254°.  A circle is 360°.  This means the arc makes up 254/360 of the circle.  We will multiply this fraction by the area of the circle, which is 

A = πr² = π(9)² = 81π = 254.34

81π(254/360) = 20574π/360 = 1143π/20 = 179.451

Janet earns 7.55 per hour mowing lawns. Kelsey earns twice that amount per hour babysitting and ty earns 1.25 less per hour than
Artemon [7]
Janet = 7.55 x 15(hours) = 113.25
Kelsey = 15.10 x 15(hours) = 226.50
Ty = 13.85 x 15(hours) = 207.76

To gets Kelsey’s wage per hour you do 7.55 x 2 and to get ty you do 15.10(Kelsey’s wage per hour) - 1.25 which is 207.76
