Answer: C. is the right answer.
Step-by-step explanation:
Given: The cost of a chessboard at Odyssey Gifts is $6.
The function F(x) = 6x gives the cost of x chessboards.
Since x is the number of chessboards, thus the domain of the function should be the set of whole numbers.
Therefore, Domain= {0,1,2,3,4,5,....................}
when we put the values for x from the domain in the function we get values multiples to 6.
therefore range of the function={0,6,12,18,24,30,......}
Hence, C is the right option.
Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
8.94427119 should be it if I’m not mistaken
.312
Frequency is 24
To find relative frequency (of Pop music) you would take 24 and divide it by the total students you were surveyed.
24/77 = .3116 rounded to hundredths becomes .312
If they are looking for percentage, you take the .312 and multiply by 100 to get 31.12%
