Answer:
c. 6/15 = 10/25
Step-by-step explanation:
Using the hint, we can form the cross products of the offered choices:
a. 6(12) vs 9(9) ⇒ 72 vs 81 . . . not a proportion
b. 8(21) vs 16(10) ⇒ 168 vs 160 . . . not a proportion
c. 6(25) vs 15(10) ⇒ 150 vs 150 . . . IS A PROPORTION
d. 4(27) vs 14(6) ⇒ 108 vs 84 . . . not a proportion
__
The cross products are the same for choice C, so that is a pair of ratios that form a proportion:
6/15 = 10/25
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
29.9 percent in decimal is 0.299
