Answer:

$55,000

Step-by-step explanation:

We have been given that Parents wish to have 90000 available for a child's education. The child is now 8 years old. We are asked to find the amount of money that parents must set aside at 5% compounded semiannually to meet their financial goal when the child is 18.

We will use compound interest formula to solve our given problem.

, where,

A = Final amount

P = Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest is compounded per year.

t = Time in years.

n=2 because it's compounded semiannually.

t=18-8 = 10

using formula for compound interest:

A= P(1+r/n)^nt

90000=P(1+0.05/2)^2×10

90000=P(1+0.025)^20

90000=P(1.025)^20

90000=P(1.63861644)

p=90000/1.63861644

P= $ 54,924.38486

to the nearest dollar P= $54,924

= $55,000 to the nearest dollar

<h3>Therefore, an amount of $$55,000 must be set aside to meet their financial goal when the child is 18.</h3>

marissa [1.9K]

Answer:

0.1667

Step-by-step explanation:

There are 6! ways to arrange the hats. The number of ways for which no guest will receive the proper hat is 5! (since there are 5 wrong hats for the first guest, 4 for the second guest, and so on). The probability that no guest will receive the proper hat is:

P=\frac{5!}{6!}=0.1667

The probability is 0.1667.

I need help with this as soon as possible!​
Kay [80]

Answer:

1. -3/6 is negative, because it descends by 3 and goes over by 6.

2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a <em>negative slope</em>.

1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:

2. vertical line

1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).

2. Thus, this means that it's a positive line since it has a <em>positive slope</em>.

1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.

2. This means that it'll have a horizontal line since there is no rise but there is a run only.
