Answer:
3/6x • 4/6x
12/6x
2x
Step-by-step explanation:
you would change both fractions to have the same denominator then simplify if needed
F(x)=6x+57
F(18)=6x+57
F(18)=6(18)+57
F(18)=108+57
F(18)=165
Answer:
x = 5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
72 + 6x + 2 + 17x - 9 = 180
23x + 65 = 180 ( subtract 65 from both sides )
23x = 115 ( divide both sides by 23 )
x = 5
Answer:
The margin of error E that corresponds to a 95% confidence level is: 
Step-by-step explanation:
The propocion is 
The sample size 
95% confidence level
Level of significance = 1-level of confidence
Level of significance = 1-0.95 = 0.05
The formula for the error is:
The value for 
according to the normal table
