Answer:
Step-by-step explanation:
The formula for simple interest is
where <em>p</em> is the principal, <em>r </em>is the rate, and <em>t</em> is the time.
The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.
Divide by 100 or move the decimal place two spots to the left.
- 2.5/100=0.025 or 2.5 ⇒ 0.25 ⇒ 0.025
Substitute the known values into the formula.
Multiply.

Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week
And: 1.25 *52=65 miles a year

Total miles : 83.2+65=148.2 miles
Answer:
The probability that an individual has the disease and has a positive test result is:
9.8%.
Step-by-step explanation:
Probability of a true positive result for a test of syphilis = 0.98 or 98%
Probability of a false negative result for a test of syphilis = 0.02 or 2% (100 - 98)
Probability of a true negative result for a test of syphilis = 0.9 or 90%
Probability of a false negative result for a test of syphilis = 0.1 or 10% (100 - 90)
Therefore, the probability that an individual has the disease and has a positive test result = 0.98 * 0.1 = 0.098 = 9.8%
