whats the formula for simple interest?....HELP

Answers

The formula for calculating simple interest is:

Simple Interest = (Principal x Rate x Time) / 100

Where:

Principal = the initial amount of money (the "principal sum")

Rate = the interest rate (expressed as a decimal or percentage)

Time = the length of time the interest is applied (usually in years)

It's important to note that simple interest is a method where the interest is calculated only on the original principal sum, not on any accumulated interest.

The simple interest formula is

i = P*r*t

where,

i = interestP = deposit or starting amount or loan valuer = annual interest rate in decimal formt = number of years

--------------------

An example:

You borrow $500 at a simple interest rate of 2% over 3 years

P = 500r = 0.02t = 3

Use those values to compute the following:

i = P*r*t

i = 500*0.02*3

i = 30

The amount of interest only is $30; meaning the total amount to pay back is $500 + $30 = $530

You roll 2 dice. How likely is it that you roll a 2 and a 5?
Impossible
Unlikely
Equally Likely
Likely
Certain

Answers

Answer:

It is likely that you roll a 2 and a 5. There are 36 possible combinations when rolling two dice, and one of those combinations is a 2 and a 5. Therefore, the probability of rolling a 2 and a 5 is 1 in 36, which is considered likely.

The answer is unlikely

Explanation: If you have two dice and roll each one once, both dice has 1 in a 6 chance of rolling a 2 and a 5. One dice has to roll a 2 and the other dice has to roll a 5. The odds of them rolling a 2 and a 5 are highly unlikely, but not impossible.

Answer: its c i just took the flvs test

Step-by-step explanation:

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that  a gamer drew one card and recorded its value.

They continued this for a total of 100 draws.

Card         A   2  3  4 5 6 7 8 9 10 J Q K

Frequency 4  7  5  6 7 6 8 10 7 10 8 12 10

The total number of cards drawn is 4+7+5+6+7+6+8+10+7+10+8+12+10 = 90.

The number of cards drawn that are either a J, Q, or K is 10+8+12 = 30.

Therefore, the experimental probability of drawing a J, Q, or K is:

30/90 = 1/3

Hence,  the experimental probability that the card selected was a J, Q, or K is 1/3.

Answers

Answer:

a=-2

b=3

Step-by-step explanation:

Solve the system of equations.

2a -5b = -19

3a + 5b = 9

Add the two equations together.

2a -5b = -19

3a + 5b = 9

------------------------

5a  =            -10

Divide by 5

5a/5 = -10/5

a = -2

Now we can find b

2a-5b = -19

2(-2) -5b = -19

-4 -5b = -19

Add 4 to each side

-5b = -15

Divide by -5

b = 3

a=-2

b=3

Given

2a-5b=  -19     (equation1)

3a+5b =  9       (equation2)

now add both equation 1 and equation 2

                       

                           2a-5b=-19

                           3a+5b= 9

                           ------------------

                             5a = -10          (as +5b and -5b get canceled)

           

5a = -10

a = -2

(substitute in equation 2 or in equation 1)

3(-2)+ 5b= 9

-6 +5b =9

5b = 9+6

5b = 15

b= 3

therefore

a= -2

b= 3

verification:

2(-2)-5(3) = -19

-19 = -19

hence verified.

0.3 is greater than 0.03

0.3 > 0.03

The 3 comes first after the decimal point in 0.3, and a 0 comes first after the decimal point in 0.03 so 0.3 is bigger.

Answer:

0.3 > 0.03

Step-by-step explanation:

I think you should watch videos on decimals to see how to do them.

You see 0.03 has two places after the decimal point while 0.3 has one place after the point. You can match them by adding a 0 to 0.3 so that it also has two places to get a clearer look.

Like this:

0.3 turns into 0.30 so now it has two places after the point like 0.03

so if there is ONLY a 0 BEFORE the point, dont think about it. so lets look at the numbers AFTER the point. We added an extra 0 after the 3 so its 30. but the other decimal is only 03, which we can look at it as just the number 3 because only 0 is in front of it and 0 equals nothing.

looking at the two numbers 30 and 3, which one is greater? 30.

Therefore, 0.3 > 0.03
