Answer:
A. True
Step-by-step explanation:
Given:
O is the center of the Circle
Chord BC is the line segment passing from the center of circle
Chord: It is a line segment whose end points lies on the circle.
Diameter: It is defined as a line segment passing from the center of the circle whose end point lies on the circle.
Hence chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle.
Hence the statement is <u>TRUE</u>
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
Answer:
57/6 or 9 1/2.
Step-by-step explanation:
The lowest common denominator is 12 so we convert the fractions to denominator 12:
29/12 + 23/6 + 11/3 - 5 / 12
= 29/12 + 46/12 + 44/12 - 5/12
= 114/12
= 57/6
or 9 1/2
