You have $50,000 in savings for retirement in an investment earning 5% annually. You aspire to have $1,000,000 in savings when y
1 answer:
Answer: It will take you about 61 years for you to reach your goal.
Step-by-step explanation:
We will represent this situation by an exponential function. So if you earn 5% yearly then we could represent it by 1.05.So in exponential function we need to find the initial value and the common difference and in this case the common difference is 1.05 and the initial value or amount is 50,000 dollars.
We could represent the whole situation by the equation.
y= where x is the number of years. so if you aspire to have 1,000,000 in some years then we will put in 1 million dollars for y and solve for x.
1,000,000 = 50,000(1.05)^x divide both sides by 50,000
20 = (1.05)^x
x= 61.40

Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation.
First, subtract 1/4 from both sides.
1/4+x-1/4<5/6-1/4
Solve.
5/6-1/4=7/12
Therefore, the correct answer is A. x< 7/12.
Answer:
The probability of choosing a person with BP who is also a runner is 2/3.
Step-by-step explanation:
According to the given data:
P( Selecting a person with high blood pressure ) = 0.3
or, P(H) = 0.3
P( Selecting a person who is a Runner ) = 0.4
or, P(R) = 0.4
Now, P( Randomly Selecting a person who has high BP and is a runner) = 0.2
⇒ P(H∩ R) = 0.2
Now, we need to find the P(randomly selected person is a runner and has already has high BP)
or we need to find: P(R/H)
now, by BAYES THEOREM:
Hence, the probability of choosing a person with BP who is also a runner is 2/3.
