1.EB is parallel to FC because they are on opposite sides and will never touch
2.scalene triangle
right angle
isosceles
3. supplementary angles add to 180 degrees
180-62=118
complementary angles add up to 90
90-62=28
4. 180 - 68 - 38 = 74
5. 6 sides=hexagon
8. sides= octagon
9. sides = nonagon
10. supplementary angles add to 180 degrees
so angle EOC is supplementary to EOF
Independent-a variable (often denoted by x) whose variation does not depend on that of another
dependant-a variable (often denoted by y) whose value depends on that of another.
Answer:
H0 : σ = 0.5
H0 : σ < 0.5
Step-by-step explanation:
From the scenario described above, the company wants to see conclusive evidence that the population standard deviation of sheath thickness is less than .05 mm ; THIS SIMPLY means ; REJECTION OF the NULL HYPOTHESIS. This is because once there is a significant or conclusive evidence in hypothesis testing, then we reject the null and support the claim of the alternative hypothesis.
Hence, the alternative hypothesis is ; population standard deviation of sheath Thickness is less than 0.5.
H1 : σ < 0.5 ;
Therefore, our null will be ;
H0 : σ = 0.5
