Answer:
8x + 12y < 240
Step-by-step explanation:
If x equals the number of small rugs and y equals the number of medium rugs dyed, we would need to multiply both variables by the number of hours taken to dye each sized rug. It takes 8 hours to dye a small rug (8x), and 12 hours to dye a medium rug (12y).
Then, to find the total number of hours they dye them in, add the terms together.
8x + 12y
The company must dye the rugs in less than 240 hours, so we will use a 'less than' (inequality) sign (it cannot be 240, or any more than 240).
8x + 12y < 240
A cluster sample is one in which the population is divided into groups and a random sample of groups is drawn.

dividing both sides by -4, we get:

this means, each term is its previous term divided by -4.
now we can construct the sequence as follows:




Answer: the last term is -1/32
M is 6 more than 10 so it will be 16
