3 different choices
Step-by-step explanation:
This problem is a combination problem: She has 3 friends, and we want to know how many groups of 2 friends there are. We can solve this using the combination of 3 choose 2:
C(3,2) = 3!(1! * 2!) = 3*2/2 = 3 possibilities
If we call her three friends A, B and C, the groups that can be formed are:
A and B
A and C
B and C
Answer:
- 3x² + x + 5
Step-by-step explanation:
Given
(4x + 5) + (- 3x² - 3x) ← remove parenthesis
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + (4x - 3x) + 5
= - 3x² + x + 5
115x + 500 = 2685
115x = 2185
x = 19

Answer/Step-by-step explanation:
The answer choices to this question showing possible set of data that could be represented by the box plot is missing.
However, here's how to find out which data set could be represented by the box plot.
The box plot given displays of a five-number summary consisting of,
1. The minimum value = 24
2. The second quartile = 27
3. The median value = 31
4. The third quartile = 33
5. The maximum value = 34
With these values known, you can easily find out which data set the box plot represents. Thus, the data set that has a min value of 24, max value of 34, and a median of 31 should be the data set that the box plot is representing. If you have more than one options having these same three values, then proceed to find the second and third quarter to determine which one is the most appropriate.
