The correct expression for a number which is 9 times as big as the number obtained after p has been increased
defon

Answer:

9(p + 4)

Step-by-step explanation:

One of the unknown variable is p.

First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).

Translating the word problem into an algebraic expression, we have;

9 * (p + 4) = 9(p + 4)

Simplifying further, we have;

9p + 36

Reil [10]

Answer:

a. 0.6

b. 0.5

Step-by-step explanation:

Let A be the event that student takes algebra and C be the event that student takes Calculus 3.

P(A)=0.60

P(C)=0.5

P(A and C)=0.30

a.

We have to find P(A/C).

P(A/C)=P(A and C)/P(C)=0.3/0.5=0.6

Thus, if someone took ​Calculus 3, the probability that he/she took ​Linear Algebra ​ too is 0.6 or 60%

b.

We have to find P(C/A)

P(C/A)=P(A and C)/P(A)=0.3/0.6=0.5

Thus, if someone took ​Linear Algebra, ​the probability that he/she took ​Calculus 3 ​ too is 0.5 or 50%

Suppose you invest $130 a month for 5 years into an account earning 8% compounded monthly. After 5 years, you leave the money, w
Zina [86]

Answer:

FV= $70,887.15

Step-by-step explanation:

<u>First, we need to calculate the future value of the $130 deposit for 5 years:</u>

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit= $130

i= 0.08/12= 0.0067

n= 5*12= 60 months

FV= {130*[(1.0067^60) - 1]} / 0.0067

FV= $9,561.96

<u>Now, using the following formula, the future value of the investment after 25 years:</u>

<u />

FV= PV*(1 + i)^n

n= 25*12= 300

FV= 9,561.96*(1.0067^300)

FV= $70,887.15
