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.

A 710 credit score is considered good. People with this credit score are likely to be approved for credit cards and loans with average interest rates and terms.
Answer:
$14,250
Explanation:
Annual depreciation = (Cost - Salvage value) / Useful Life
Annual depreciation = ($60,000 - $3,000) / 8
Annual depreciation = $57,000 / 8
Annual depreciation = $7,125
Accumulated dep. at December 31, 2022 = $7,125 * 2
Accumulated dep. at December 31, 2022 = $14,250
So, the balance in accumulated depreciation using the straight-line method at December 31, 2022 is $14,250.
Answer:
false
His purchase left GDP unchanged
Consumption of non durables would increase.
Also, net export would decrease.
these effects would cancel out
Explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export
Net export = exports – imports
Answer:
E). Use inexpensive digital marketing tools to inform the community about an upcoming fundraising event.
Explanation:
The 'use of inexpensive digital marketing tools for informing the community regarding the approaching fundraising event' would be the most appropriate and feasible for the non-profit organization as it would be the most reasonable for the firm. A big-budget expense on marketing the event would neither be affordable due to the small budget nor beneficial for such an organization. Thus, using inexpensive digital marketing would publicize the event on an affordable budget and prove helpful in gathering good collections in the event. Hence, <u>option E</u> is the correct answer.
