Step-by-step explanation:
Given : Margin of error : E= 17
Standard deviation : 
Critical value for 90% confidence level :
Formula to find sample size is given by :-

i.e. 

Hence, the required minimum sample size = 46.
Answer:
x = 11
Step-by-step explanation:
C is the circumcenter of 
(Radii of same circle)





A triangle with sides measuring 300, 400 and 700 because 300+400+700=1400 which is higher than the first triangle 300+400+500=1200
6x - 4 < 8
Add 4 to both sides:
6x < 12
Divide both sides by 6:
x < 2
Answer: x < 2
Answer:
With probability you can multiply your chances in this case.
Getting an odd number: 1/2
Getting a number greater than 4: 1/6
Therefore it is a 1/12 chance to be both odd and greater than 4
