Answer:
There is a 3/20 chance that a red plastic marble will be taken out on random.
Step-by-step explanation:
This is because there are 14 yellow marbles, and 6 red marbles. Along with this, half of the red marbles are made out of plastic. This leaves 3/6 of the red marbles made out of plastic. When combined with the yellow marbles, you'll add 14 to the denominator, since there are 14 yellow marbles. (Red + Yellow = Total Number Of Marbles) This leads to a total count of 3 marbles of the 20 total marbles, being red and made out of plastic.
Given:
The graph of a number line.
To find:
The set of values for the given number line.
Solution:
As we move from right to left on a number line the values decreased however as we move from left to right on a number line the values increased.
From the given number line it is clear that there is an open circle at 7 and a close circle at 10. It means 7 is not included in the solution set but 10 is included in the solution set.
From the point 7, the arrow approaching to the left it means all the values less than 7 are included in the solution set, i.e., x < 7.
From the point 10, the arrow approaching to the right it means all the values greater than 10 or equal to 10 are included in the solution set, i.e., x ≥ 10.
Solution set : x < 7 or x ≥ 10.
Therefore, the correct option is A.
Step-by-step explanation:
Cosine Ratio is the best tool to solve this problem.
cos38°=x/8
x =8*cos38°
x = 8*0.79
x = 6.32
Part A. For finding the quartiles, box plot would be the best to represent the range of scores of the students.
Part B. The first step is to order the data: 2 3 3 3 3 4 5 6 7 8 14. Next, you will find the median. The median is 4. So, second the quartile = 4 The median splits the remaining data into two sets. The first set is 2 3 3 3 3 and the median of this set is 3. So, first quartile = 3. The second set is 5 6 7 8 14 and the median of this set is 7. And the third quartile = 7
