Answer:
64% of Americans say social media have a mostly negative effect on the way things are going in the U.S. today. Just one-in-ten Americans say social media sites have a mostly positive effect on the way things are going, and one-quarter say these platforms have a neither positive nor negative effect
Step-by-step explanation:
Solution :
Here we can use the Binomial distribution, as there are only two possible outcomes.
The given data:
n = 150
q = 98%
= 0.98
p = probability of not finding relief = 1 - 0.98
= 0.02
A). The number of the individuals who do not find any relief from sinusitis is :
E(x) = np
= 150 x 0.02
= 3
B). The uncertainty of my estimate is = ![$\sqrt{npq}$](https://tex.z-dn.net/?f=%24%5Csqrt%7Bnpq%7D%24)
![$=\sqrt{150 \times 0.02 \times 0.98}$](https://tex.z-dn.net/?f=%24%3D%5Csqrt%7B150%20%5Ctimes%200.02%20%5Ctimes%200.98%7D%24)
= 1.716
Y+y = 2y
adding like terms
Answer:the answer is 560
Step-by-step explanation:
The reason is because you multiply to get 8 and 40 to get the amount for regular time which is 320.Then you subtract 60 from 40 which is 20.You multiply that amounnt by 12 because that is the overtime which will equal 240.Add them together and you get 560. ☺
5.2% = 0.052
1/7 = 0.14
-11/5 = -2.2
From the greatest to least:
![0.14>0.052>-0.8>-2.2](https://tex.z-dn.net/?f=0.14%3E0.052%3E-0.8%3E-2.2)
The second number is: 5.2%
Answer:
5.2%
