Answer:
0.022
Step-by-step explanation:
Given that :
Population size = 25000
n = 500 ; p = 0.4
Size of random sample (n) = 500
5% of population size : 0.05 * 25000 = 1250
Distribution is normally distributed since n < 5% of population size
Hence, the mean of the distribution = p = 0.4
Standard deviation = √((pq) /n)
q = 1 - p ; q = 1 - 0. 4 = 0.6
Standard deviation = √((0.4 * 0.6) /500)
Standard deviation = 0.0219089
= 0.022
Answer:
Can u please correct this.
360° is the correct answer
Answer:
<u>x = 8</u>
Step-by-step explanation:
The sides are in proportion.
- 40 / 7x + 14 = 44 / 33 + 44
- 40 / 7x + 14 = 44/77 = 4/7
- 40(7) = 4(7x + 14)
- 280 = 28x + 56
- 10 = x + 2
- <u>x = 8</u>
