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:
$6,809.04
Explanation:
Calculation to determine what her net pay for the month is
Gross Pay (a) $8,988

Medicare Tax $130.33
($8,988 * 1.45%)
Federal income Tax $1,491.37
Total Deductions (b) $2,178.96
Net Pay (a-b) $6,809.04

sales era
Explanation:

Answer:
Radar's additional income for accepting the order is calculated as follows:
Sales - 320 x $460 = $147,200
less Cost of Sales = 320 x $180 + $48,000 = $105,600
Additional Income = $41,600
Explanation:
The additional income of $41,600 is $147,200 - $105,600, which is the result of deducting cost of sales from Sales.
The cost of sales includes the variable cost per bike, including the incremental fixed costs ($48,000) to make this order.
To make a decision whether to accept an order or not, the company needs to consider all variable costs, including the incremental fixed costs. The resulting additional income is what is available to offset the fixed costs.
Answer:
$112,600
Explanation:
Calculation for What is the amount of Alice's Taxable Income
Wages $120,000
Add Dividend Income $5,000
Adjusted Gross Income $125,000
($120,000+$5,000)
Less Standard Deduction(Single and no dependents) ($12,400)
Taxable Income $112,600
($125,000-$12,400)
Therefore the amount of Alice's Taxable Income will be $112,600
