Result
a) There is sufficient evidence to reject the claim that the two methods provide the same mean value for natural vibration frequency.
b) (-10.9646, -0.0068)
Answer:
Step-by-step explanation:
b , n, and a are variables so you cant solve but can be put in an equation which is b+a/n
Answer:
The answer is 17 2/5
Step-by-step explanation:
To find this, first add all the fractions together.
1/5 + 2/5 + 4/5 = 1 2/5
Now add all the whole numbers together.
8 + 3 + 5 = 16
Now add the two together.
16 + 1 2/5 = 17 2/5
Answer:
A
Step-by-step explanation:
given 
= 
using the method of cross- multiplication then
8P = 42 ( divide both sides by 8 )
P = 
= 5.25
