Answer:
153 times
Step-by-step explanation:
We have to flip the coin in order to obtain a 95.8% confidence interval of width of at most .14
Width = 0.14
ME = 
ME = 
ME = 

use p = 0.5
z at 95.8% is 1.727(using calculator)





So, Option B is true
Hence we have to flip 153 times the coin in order to obtain a 95.8% confidence interval of width of at most .14 for the probability of flipping a head
Yes you can! Say you have 5(2 + x) + 3x. The answer would be 10+8x because when you use the distributive property you will end up getting 5*2 5*x and once you multiply, it's obvious 5 times 2 is 10 and 5 times x will equal 5x. Then you add 5x and 3x and get 8x. So, the simplified expression here is 10+8x. When you have this as an answer it's proving your answer right. You can without using the distributive property. We can have 10+5x+3x and it will be your simplified expression. It's the same thing with equations too.
If sqrt x = 9 then x = 9*9 = 81
Answer is between 80 and 90.
Answer:
No
Step-by-step explanation:
n₁=4
n₂=9
n₃=16
We can see that all three numbers are perfect squares of one higher than the figure number
So, n₁₅=(15+1)²=16₂=256
256≠225
