Answer:
B) Principal: the amount of money you initially invested
Step-by-step explanation:
The given formula I=P·r·t is of Interest
In this formula
I is simple interest
r is the interest rate
t is the amount of time
P is the principle amount invested on which interest is calculated
hence of the given options, option b is correct i.e.
Principal: the amount of money you initially invested !
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
There are no parentheses or exponents in this expression, so to the next step (Multiplication/Division)
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right.
In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
50÷5+3×4÷2-1
50 ÷ 5 = 10
10 + 3 × 4 ÷ 2 - 1
3 × 4 = 12
10 + 12 ÷ 2 - 1
12 ÷ 2 = 6
10 + 6 - 1
Addition/Subtraction
10 + 6 - 1
10 + 6 = 16
16 - 1
15
Hope this helped!

Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation :D give me brainly
<u>7/11</u> is the final answer.
use the formula for disjointed events: P(A or B) = P(A) + P(B)
=================================
P(A or B) = P(A) + P(B)
P(A or B) = 4/11 + 3/11
P(A or B) = 7/11
