Answer: 8x+y

Step-by-step explanation:

you always combine your like terms, a trick is to put a line infront of your equation signs making it look like 3x/+2y/+5x/-y. This makes it easier to see if your terms are positive or negative. Now you have 5x+3x and 2y-y giving you 8x+y because its still positive.

Which of the following numbers would be an outlier if added to the data set below?
Andrew [12]

Answer:

406,209,308

According to their deviation from the mean 350.25

Step-by-step explanation:

To Know an outlier we'll determine it by looking for the mean of the data set first then checking the deviation of the numbers each from the mean.

Mean = (372+351+299+406+387+315

+364+308)/8

Mean =2802/8

Mean= 350.25

Ok now let's determine the deviations

372 - 350.25= 21.75

351 - 350.25= 0.75

299- 350.25= -51.25

406 - 350.25= 55.75

387 - 350.25= 36.75

315- 350.25 = -35.25

364- 350.25= 13.75

308- 350.25= -42.25

According to the magnitude of the deviation 406 and 299 has the highest deviation so they are the outliers followed by 308
