Answer:
10000000
Step-by-step explanation:
200000000/2 = 100000000
Then 100000000/10 = 10000000
Answer:
At 90% confidence interval, the estimate of the mean breaking weight is (770.45, 778.15)
Step-by-step explanation:
Given that:
sample size n =43
sample mean x = 774.3
standard deviation = 15.4
confidence interval = 90%
At C.I of 90% , the level of significance ∝ = 1 - C.I
the level of significance ∝ = 1 - 0.90
the level of significance ∝ = 0.10
The critical value for z at this level of significance is 
= 1.64
The margin of error can be computed as follows:
Margin of error = 
Margin of error = 
Margin of error = 
Margin of error = 
Margin of error = 3.8515
The mean breaking weight for the 90% confidence interval is = 
= 
= ( 774.3 - 3.8515 < μ < 774.3 + 3.8515 )
= (770.4485, 778.1515)
(770.45, 778.15)
Answer:
sin ^2 x+ cos ^2 x = 1
Step-by-step explanation:
sin^2 x - cos ^2 x sin ^2 x = sin ^4 x
Factor sin^2 x
sin ^2 x ( 1- cos ^2 x ) = sin ^4 x
Using the identity sin ^2 x+ cos ^2 x = 1 written as 1 -cos ^2 x = sin ^2 x
sin ^2 x ( sin^2 x ) = sin ^4 x
sin ^4 x = sin ^4 x
