Answer:
c from transmitter to a receiver
Answer:
874 psi
Explanation:
Given a sample mean (x') = 900,
and a standard error (SE) = 10
At 99% confidence, Z(critical) = 2.58
That gives 99% confidence interval as,
x' ± Z(critical) x SE = 900 ± 2.58 x 10
The value of the lower limit is,
900 - 25.8 = 874.2
≈ 874 psi
Answer:
<em>hello your question is incomplete attached below is the missing diagram </em>
answer : 7.87 KN
Explanation:
The magnitude of the resultant force = 7.87 KN
from fig 1
First step :
calculate the resultant force along the x- direction
Frx = ∑Fx = +8 kN - Fcos45° - 14cos 30°
= -4.1243 - 0.7071 F
next :
calculate the resultant force along the y- direction
Fry = ∑Fy = -Fsin45° + 14sin30°
= -0.7071 F + 7
attached below is the remaining part of the detailed solution
