Answer:
The correct answer is C: $4300
Explanation:
Giving the following information:
They will invest an equal amount each month for 5 years.
This account will earn 6% per year(0.5% per month)and will have $300,000 at the end of the 5-year term
We need to use the following formula:
final value= {A[(1+i)^n-1]}/r
A= cuota
i= monthly interest
n= 60 months
Isolating A:
A= (FV*i)/[(1+i)^n-1]
A= (300000*0.005)/[(1.005^60)-1]
A= 1500/0.34885= 4300
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:
Total Revenue of Cocaine will increase.
Explanation:
Elasticity of demand is demand responsiveness to price change.
Price & Total Revenue have relationships as per Elasticity of Demand :
- Elastic Demand >1 : Change in quantity demanded > change in price ; Price & Total Revenue negatively related.
- Inelastic Demand < 1 : Change in quantity demanded < price change ; Price & Total Revenue positively related
Given : Demand for crack cocaine is inelastic. If government increases penalties on cocaine supply, number of dealers decrease.
Then , the supply of cocaine will fall. Supply Shortage will increase the price. However - because demand is inelastic , total revenue will increase as a result of price rise.
Answer:
The thief has a 0.11% probability of hitting the pin code on the first try.
Explanation:
Simply, if the ATM card has a 3-digit code that can be repeated, and the board has 9 numbers (for example, from 1 to 9), we must start from the smallest number that could be formed with these numbers to the highest number that these numbers could also compose, which in the case would be 111 and 999. Then, 889 different numbers could be formed (it is the distance between 111 and 999), with which the possibility of hitting the key to the first attempt would be 1 in 889 times, or 1/889.
To take the probability to a percentage, we must know that 889 / 8.89 gives 100. Therefore, dividing 1 / 8.89 we will know the percentage of probabilities of hitting the key on the first attempt: 1 / 8.89 = 0.11.
This shows us that the thief has a 0.11% probability of hitting the key on the first try.
