Answer:
The average velocity of the car was zero because the displacement was zero.
Explanation:
Average velocity is the rate of change of displacement with time. Mathematically, it is calculated as follows;
where;
x₁ is the initial position or starting point of the car
x₂ is the final position or finishing point of the car
t₁ is the initial time = 0
t₂ is the final time = 2 hours
The average velocity can be zero if the initial position of the car is equal to its final position. In this condition, the displacement of the car is zero.
Therefore, the average velocity was zero because the displacement was zero.
Answer:
Explanation:
Number of bulbs = 20
Success of a bulb lightning properly = 0.92
Success of a bulb not lightning properly = 0.08
We have to find the probability of atmost 3 bulbs not lightning properly -
The random Variable X follows binomial distribution
= 0.929385
Mean and variance of bulbs in a string that are not lightning properly is given by
Mean of binomial distribution or E(X) = n*p = 20*0.08 = 1.6
Variance of binomial distribution or V(X) = n*p*(1-p) = 20*0.08*0.92 = 1.472
They were fighting the russians and lost.
Answer:
Production budget = 76, 000 units
Explanation:
<em>The sales budget is adjusted for the projected opening and closing inventories unit to arrive at the production budget: </em>
The production budget can be determined using the formula below
Production budget = Sales budget + closing inventory- opening inventory
Production budget = 67,000 + 15,000 - 6,000
= 76000
Production budget = 76, 000 units
Answer:
A- Tactics relate to specific actions whereas strategy relates to the overall plan.
Explanation:
In the military, tactics are the means used to achieve an objective, while strategy is the overall plan to be achieved. In other words, <em>tactics are specific actions taken to achieve the strategy</em>. In warfare, achieving a strategy involves key and complex steps and decisions.
For example, in winning a war against another country, obliterating their military forces to wreck the nation's ability to wage war could be a strategy. The tactics involved on the other hand will be more specific actions like missile attacks, unexpected attacks on their facilities and so on.
Tactics and Strategy are interwoven, strategy being the envelope covering tactics employed in warfare.
