The researcher wants to investigate whether carpet makes a difference in the mean bacterial concentration in air. the null and alternative hypotheses would be:

H0: The mean of the carpeted rooms = the mean of the uncarpeted rooms

Ha: The mean of the carpeted rooms ≠ the mean of the uncarpeted rooms

The attention of bacteria majorly depends on the awareness of inoculum, incubating temperature, and the metabolic country of inoculated pressure used. The bacterial concentration suspended in growth media may be calculated.

In idea, you could listen to cells through filtration or centrifugation, but likely no greater than a hundredfold. for your case, you're asking to concentrate by 10,000 fold. So you sincerely might want to develop denser cultures of cells. You can centrifuge your modern broth and resuspend the pallet in a clear broth.

In microbiology, the minimal inhibitory attention (MIC) is the lowest concentration of a chemical, generally a drug, which prevents the visible boom of a bacterium or bacteria.

Answer:

Cash Dividends - Year 2 =  $84400

Explanation:

The net income of the business is usually appropriated or used for two purposes at the end of the year. It is either used to pay dividends or is retained in the business and is added to the retained earnings or both.

Thus, to calculate the dividends paid by the business in a particular year, we can calculate the change in retained earnings and deduct it from the net income.

Change in retained earnings = Ending balance of retained earnings - Beginning balance of retained earnings

Change in retained earnings = 694000 - 587400

Change in retained earnings = $106600

Thus, out of the net income of $191000, $106600 were transferred to retained earnings. So, the amount of dividends paid for the year is,

Cash Dividends - Year 2 = 191000 - 106600  = $84400

Which organization or agency assists the fire department by alerting the public of traffic incidents or evacuations?
MariettaO [177]

Media is the organization or entity that would help the fire department with incident scene security, crowd control, and explosives disposal.

Law enforcement is the organization or entity that would support the fire department with incident scene security, crowd control, and explosives disposal. Law enforcement forces respond to emergencies around the clock and operate under a paramilitary command structure. In most traffic situations, officers act alone and are taught to make unilateral command judgments. Fire and rescue services respond to emergencies around the clock and follow a well-defined command structure on the scene. The core constituency of traffic incident management consists of eight key disciplines: law enforcement, fire and rescue, emergency medical, transportation, towing and recovery, hazardous materials cleanup, public safety communications and dispatch, and traffic reporting.

We can calculate the cost of goods manufactures using the formula:

Total Cost = Cost of Direct Materials + Direct Labor Cost + Overhead Cost – Inventory

Substituting the known values:
