Answer:
1/3 is the answer.
Step-by-step explanation:
Tanya prepared 4 different letters to be sent to 4 different addresses.
To solve this we can do the following:
The probability that the 1st letter is in the right envelope is = 
The probability that the 2nd letter is in the wrong envelope is = 
The probability that the 3rd letter is in the wrong envelope is = 
The probability that the 4th letter is in the wrong envelope is = 1
So, the answer becomes: 
= 
As we need 4 correct letters in the envelope, we will multiply by 4:
By using the formula pie radius squared times the height
Answer: the answer is 4,598.
Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.
So, you can go through each of your options to see which ones work with those rules.
A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span>
, menaing A is a fraction, which you can't have.
B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.
C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.
D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.
So,
C and
D are both written in Standard Form.
