Answer:
<u>The principal of the investment is $ 500</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Interests = $ 60
Interest rate = 12% annually = 0.12
Time = 1 year
2. Find the principal.
Let's use the formula given:
Interests = Principal * interest rate * time
Replacing with the real values, we have:
60 = Principal * 0.12 * 1
0.12 * Principal = 60
Principal = 60/0.12
Principal = 500
Answer:
X = 2550
Step-by-step explanation:
Convert 12% to a decimal:
⇒ 12% = 12/100 = 0.12
12% of X is 306
⇒ 0.12X = 306
⇒ X = 306 ÷ 0.12
⇒ X = 2550
<h3>
Answer: $7,853.16</h3>
Work Shown:
A = P*(1+r/n)^(n*t)
A = 4750*(1+0.10/2)^(2*10)
A = 12,603.164099436
A = 12,603.16
That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.
interest = A-P = 12,603.16 - 4,750 = 7,853.16
Answer:
What is the probability formula?
Image result
In general, the probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
-3x-6/x+2
-3(x+2)/x+2
-3 is the answer
