To add 7.5% to a number you simply multiply the number by 1.075. To compound that amount year after year, you raise 1.075 to an exponent that corresponds to the number of years. 2600*(1.075^8)=<span>4637.04234646</span>
Answer:
<h2>181 440</h2>
Step-by-step explanation:
We have 9 choices for Choosing the first object
8 choices for Choosing the 2nd object
.
.
.
3 choices for Choosing the seventh object
Therefore if we want to choose7 objects without replacement from 9 objects we have : 9×8×7×6×5×4×3 = 181 440
Also ,we can calculate it this way :
9P7 = 181 440

Finding two geometric means between 10 and 125:
a 1 = 10, a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
Answer: The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
Answer:
Step-by-step explanation:
Let assume that Suppose the chance of contracting malaria is 10% for those who are not vaccinated ; (since the value) is not given.
Thus;
If the vaccine has no effect, risk of malaria for vaccine and no vaccine are equal to 0.1
Probability of not getting malaria if vaccinated or no vaccinated = 1 - 0.1 = 0.9
Malaria No Malaria Total
Vaccinated 100 * 0.1 = 10 100 * 0.9 = 90 100
No Vaccine 200 * 0.1 = 20 200 * 0.9 = 180 300-100 = 200
Total 20 + 10 = 30 90 + 180 = 270 300
If the vaccine cuts the risk by half, risk of malaria for vaccinated are equal to 0.1/2 = 0.05
Probability of not getting malaria if vaccinated = 1 - 0.05 = 0.95
Malaria No Malaria Total
Vaccinated 100 * 0.05 = 5 100 * 0.95 = 95 100
No Vaccine 200 * 0.1 = 20 200 * 0.9 = 180 300-100 = 200
Total 20 + 5 = 25 90 + 180 = 275 300
