If the mean of the following set is 12, what is x?
(1,14,3,15,16,x,21,10)

To find what x is you must first make a solvable equation. You can take your knowledge of finding mean to do this

To find the mean of a set of data you must add the data together then divide the sum by the number of data in the set. You can make an equation from this and set it equal to 12 like so:

First combine like terms:

You can split up the fraction like so:

= 12

Now you can simplify to 10

10 + = 12

Now bring 10 to the right side by subtracting 10 to both sides (what you do on one side you must do to the other). Since 10 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

10 - 10 + = 12 - 10

= 2

Now we must completely isolate x. To do this you must multiply 8 to both sides. Since x is being divided by 8 you must multiply 8 to both sides to make 8 one on the left side and bring it over to the right side

× 8 = 2 × 8

x = 16

Hope this helped!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
