Answer:
19. 13 20. 9 21. 12 22. 21
Step-by-step explanation:
lets say there are 100 girls.
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.
in simplest fraction form, 60/100= 3/5
To do this, divide the total square footage by its square root. The square root of 9 is 3. 9 divided by 3 is 3. All sides of the green square are 3 ft in length. The square root of 16 is 4. 16 divided by 4 is 4. All the sides of the red square are 4 ft in length.
Answer:
First choice.
Step-by-step explanation:
When you solve the system and somehow get both sides two different value. That means both graphs are oarallel (graph of both equations). When two sides are different, we can say that there are no solutions.
Answer:
Clusters at 1 - 2 1/2 and 3 1/2 - 4
Gaps at 1/2 and 3
Spread from 0 - 4
Peak at 4
Graph is not symmetrical.
Explanation:
The clusters are where the data is grouped <em>without </em>gaps. So from 1 - 2 1/2 and 3 1/2 to 4. There are no gaps. Gaps are spaces <em>without</em> data. These spaces have to be within the spread of the data. The spaces without data within the spread are 1/2 and 3. The spread is the smallest data point to the largest one. The peak is the data point with the most dots. The place with the most dots is 4. A symmetrical graph has a center point that everything revolves around and everything is the same on both sides. There is no symmetry in this graph.
