Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599

Answer:
is this a poem or something
The image that has the 10N forward force alone is the fastest while the image that has the 10N forward force and two 5N backward forces is the slowest.
<h3>What is acceleration?</h3>
The term acceleration refers to the change of velocity with time. The acceleration of a body depends on the mass of the body and the force acting on it.
Looking at the image attached, the image that has the 10N forward force alone is the fastest while the image that has the 10N forward force and two 5N backward forces is the slowest.
