Answer:
10 inches (10.19)
Step-by-step explanation:
Answer:
H0: u ≥ 9.5
Ha: u < 9.5
Step-by-step explanation:
The null hypothesis and the alternate hypothesis are reverse of each other.
The claim is either set as the null or alternate hypothesis
The null hypothesis is : H0: u ≥ 9.5 the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.
The alternate hypothesis is: Ha: u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is not considered equivalent to the standard.
102/159 = x/4
34/53 = x/4
34(4) = x(53)
136 = 53x
136/53 = x
The given states that line BC is congruent to line EC and line AC is congruent to line DC. By the vertical angles theorem, angle BCA is congruent to angle DCE. By SAS, triangle BCA is congruent to triangle DCE. Using CPCTC, it can be concluded that line BA is congruent to line ED.
Answer:
Option 4
Step-by-step explanation:
Given:
Sinθ = 
Since, cos2θ = 1 - 2sin²θ
cos2θ = 
cos2θ = 1 - 
cos2θ = 
cos2θ = 
Therefore, Option 4 will be the answer.
