If you would like to know which one of the options is better to buy, you can calculate this using the following steps:
3 sandwiches ... $4.95
1 sandwich ... $x = ?
______________________
3 * x = 1 * 4.95 /3
x = 4.95 / 3 = $1.65
4 sandwiches ... $6.72
1 sandwich ... $y = ?
______________________
4 * y = 1 * 6.72 /4
y = 6.72 / 4 = $1.68
Result: You should buy sandwiches from the first option ($1.65 < $1.68 per unit).
28. 5T<1.5 is the answer. would you like 27 too?
Answer:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
Step-by-step explanation:
For this case we have the following data:
5.7 7.2 7.3 6.3 8.1 6.8 7.0 7.6 6.8 6.5 7.0 6.3 7.9 9.0 8.2 8.7 7.8 9.7 7.4 7.7 9.7 7.8 7.7 11.6 11.4 11.8 10.9
The first step on this case is order the dataset on increasing way:
5.7 6.3 6.3 6.5 6.8 6.8 7.0 7.0 7.2 7.3 7.4 7.6 7.7 7.7 7.8 7.8 7.9 8.1 8.2 8.7 9.0 9.7 9.7 10.9 11.4 11.6 11.8
Then we can construct the stem leaf plot like this:
Stem Leaf
5 | 7
6 | 3 3 5 8 8
7 | 0 0 2 3 4 6 7 7 8 8 9
8 | 1 2 7
9 | 0 7 7
10 | 9
11 | 4 6 8
Notation: 5|7 means 5.7 and 11|4. means 11.4
2 - 5x - 24 = 0 (calculate)
-22 - 5x = 0 (move the constant to the right)
-5x = 22 (divide both sides)
x = -22/5
It did change the reason was because teh age gap was digpffenrent
