Answer:

3.46 m/s

Explanation:

This is actually a Physics question and not a Business question.

According to the property of conservation of momentum, the speed of the Mazda before the collision multiplied by the mass of the Mazda must equal the speed after the collision multiplied by the mass of both cars:

m_1v_1=(m_1+m_2)*v_2\\940*12.5=(940+2460)*v_2\\v_2= 3.46\ m/s

The post-collision speed of the two entangled cars is 3.46 m/s.

Answer:

The order of questions most objetive and unbiased is first (a) and then (b)

Explanation:

The order of the questions influences the answer of the people. If you ask first about dating, when they answer the question about happiness, the second answer would focus on the happiness it brings if they are datting. That means that I am inducing an answer about the happines of being dating or not, that is not ethical and the survey is not objetive. If the order of the questions is first (a) and the (b), the answer about happiness is not focused in the sentimental situation, and you can find if there is a correlation betwen the happiness and dating.

vodka [1.7K]

Answer:

<u>A) conditions in the target industry allow for profits and return on investment that is equal to or better than that of the company's present business(es).</u>

<u>Explanation</u>:

Remember, the key word here is about whether diversification into a particular industry would likely increase shareholders value.

Thus, any company wanting to test this out would consider whether conditions in the target industry allow for profits and return on investment that is equal to or better than that of the company's present business(es).

This option is better because improved profits implies better shareholder value.

AlekseyPX

Answer:

c. $52,670

Explanation:

The computation of the fixed cost and the variable cost per hour by using high low method is shown below:

Variable cost per desk = (High cost - low cost) ÷ (Highest production - lowest production)

= ($82,700 - $63,300) ÷ (3,500 desk - 1,240 desk)

= $19,400 ÷ 2,260 desk

= $8.58

Now the fixed cost equal to

= High cost - (High production × Variable cost per desk)

= $82,700 - (3,500 desk × $8.58)

= $82,700 - $30,030

= $52,670
