Artemon [7]4 years ago

<span>Assuming a normal distribution the noise level is below 44dB 90% of the time. Looking up the standard deviation that goes along with .01 on a normal distribution chart, we find that 2.33 standard deviations is the answer. Given the standard deviation of six we turn this in to deviation in decibels from the mean: 6*2.33 = 13.98 Add this to the mean to get 30+13.98=43.98 which we round to 44dB</span>

Leno4ka [110]

Answer:

Productivity is measured by the amount of output per unit of input.

In this case, the inputs will be the hours spent doing research and writing their essays. Output will equal the amount of pages written.

Marci spent 8 hours and wrote a 26 page long report, so her productivity = 26 pages / 8 hours = 3.25 pages per hour

Jack spent 20 hours and wrote a 26 page long report, so his productivity = 26 pages / 20 hours = 1.3 pages per hour

Marci is much more productive in terms of hours spent doing and writing, and how long the report is.

The problem with this type of analysis is that we do not know if Marci's report was good or bad, and the same applies to Jack's. Since we do not know what grade they got, we cannot be sure how effective their work was.

QveST [7]

Answer:

B) an agency relationship.

Explanation:

A contract can be defined as an agreement between two or more parties (group of people) which gives rise to a mutual legal obligation or enforceable by law.

There are different types of contract in business and these includes: fixed-price contract, cost-plus contract, bilateral contract, implies contract, unilateral contract, adhesion contract, unconscionable contract, option contract, express contract, executory contract, etc.

In this scenario, Consolidated (principal) empowers Doha Ltd., an Egyptian firm to enter into contracts in certain countries on behalf of Consolidated. Thus, this is an agency relationship.

An agency relationship can be defined as a mutual relationship existing between two parties, wherein a principal authorizes the agent to act as the principal's representative or on his behalf (fiduciary role) in dealing with third parties.

Basically, Consolidated is the principal based on the agency relationship while Doha Ltd. is considered to be an agent and as such is authorized or empowered to enter into contracts in certain countries on behalf of Consolidated.

A machine cell uses 192 pounds of a certain material each day. Material is transported in vats that hold 22 pounds each. Cycle t
kari74 [83]

Answer:

Number of vats is 1.75 or 2

Explanation:

given data

Cycle time for the vats  T = 1.50 hours

Material is transported C = 22 pounds

inefficiency factor X =  0.07

to find out

How many vats will be used

solution

we get here planned used rate that is

planned used rate = \frac{192}{8}

planned used rate = 24 pieces per hour

so here total no of container will be

N = \frac{DT(1+X)}{C}   ..............1

here N is total no of container

put here value and we get

N = \frac{24*1.50*(1+0.07)}{22}

N = 1.75

so Number of vats is 1.75 or 2
