The variable x is the weight of the letter and they subtract 1 from that, so adding the 0.50 at the end of the equation would be the cost for a one ounce letter.
The answer is:
A) The cost, in dollars, to mail a one ounce letter
Step-by-step explanation:
Data Set A: 14, 21, 24, 28, 28, 35
Data Set B: 18, 19, 21, 25, 29,32
Median:
Data Set A = 26
24 + 28 = 52
52/2 = 26
Data Set B = 23
21 + 25 = 46
46/2 = 23
Mean:
Data Set A = 25
14 + 21 + 24 + 28 + 28 + 35 = 150
150/6 = 25
Data Set B = 24
18 + 19 + 21 + 25 + 29 + 32 = 144
144/6 = 24
I believe it would be -0.5, because you’re going down by half. If I’m incorrect, I’m sorry.
Answer:
1/5 = 3/15
2/3 = 10/15
When all Added up
= 13/15
Step-by-step explanation:
So our LCD here is 15.
So in order to go from 5 to 15, we multiply by 3, and In order to go from 3 to 15, we multiply by 5. What we do to the denominator we also do to the numerator.
So,
And,
So there you go, multiply for what you need to get to the LCD, and what is done to the numerator is also done to the denominator. Enjoy
