Answer:
For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30
Step-by-step explanation:
For a data from population which is not normally distributed, the sample means would be approximately a normal distribution if the sample size (n) is greater than 30 i.e n ≥ 30 this is because the shape of a sample distribution depends on the sample size. But for normal distribution population, the sample means would be approximately a normal distribution even if the sample size is less than 30;
Answer: 56
Step-by-step explanation:
4=(a+b-24)/2
32=a+b

(3,9) is reflected to(-3,9)
(7,2) is reflected to(7,-2)
(-3,-9)is reflected to (-3,9)
Answer:
Step-by-step explanation:
as (c + 9)(c - 9) = c² - 81
and (c - 9)(c + 6) = c² - 3c - 54
<u> 8(c + 6) </u> = <u> 8c + 48 </u>
(c² - 81)(c + 6) (c - 9)(c + 9)(c + 6)
<u> 10c(c + 9) </u> = <u> 10c² + 90c </u>
(c² - 3c - 54)(c + 9) (c - 9)(c + 9)(c + 6)
