Answer: 0.0475
Step-by-step explanation:
Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.
Where , Population mean :
Standard deviation :
To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.
∵
Then , for x= 3,000,000
Then , the probability that the firm’s sales will exceed $3 million is given by :-
Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
Answer:
Hydrostatic force = 7800N
Step-by-step explanation:
The hydrostatic force is the force on a body when there is change its in hydrostatic pressure on the surface of the body when its equilibrium position shifts.
Let us first look at the formula for hydrostatic force
hydrostatic force = the pressure at the center x the area
Pressure = density x gravity x height
hydrostatic force = [sqrt(4)/2 m][1000 kg/m^3 * 9.8m/s^2] x [(1/2)(4)(4sqrt(4)/2) m^2]
Calculating the above data we get;
Hydrostatic force = 7800N
128 x 5= 640 which is 100% 640/128= 20
640 x 20%= 128
