Answer:
EH = 120 degrees
Step-by-step explanation:
angles in a circle add up to 360 degrees
arc EF + arc FG + arc GH + arch EH = 360
95 + 90 + 55 + EH = 360
240 + EH = 360
subtract 240 from both sides to isolate EH
EH = 120 degrees
Answer:63%
Step-by-step explanation:
if 2years=25%loss
Then 5years=5/2×25%
=62.5%~63%
Let p be the proportion. Let c be the given confidence level , n be the sample size.
Given: p=0.3, n=1180, c=0.99
The formula to find the Margin of error is
ME = 
Where z (α/2) is critical value of z.
P(Z < z) = α/2
where α/2 = (1- 0.99) /2 = 0.005
P(Z < z) = 0.005
So in z score table look for probability exactly or close to 0.005 . There is no exact 0.005 probability value in z score table. However there two close values 0.0051 and 0.0049 . It means our required 0.005 value lies between these two probability values.
The z score corresponding to 0.0051 is -2.57 and 0.0049 is -2.58. So the required z score will be average of -2.57 and -2.58
(-2.57) + (-2.58) = -5.15
-5.15/2 = -2.575
For computing margin of error consider positive z score value which is 2.575
The margin of error will be
ME = 
=
= 2.575 * 0.0133
ME = 0.0342
The margin of error is 0.0342
Answer:
79.6
Step-by-step explanation:
4 3/5+15÷1/5
23/5+15÷1/5
4.6+15÷0.2
4.6+75
