The answer to your question is 11 world championships
Answer:
Step-by-step explanation:
Range = difference between the highest and the lowest
Mode = Data that occurs the most time
Median = Arrange the data in ascending order. The middle data is the median. If number of data is even, median is the average of the two middle terms.
1) Range = 28 -21 = 7
Mode = 25
Number of data (Count the total dots) = 14
Median = average of 7th and 8th term
Median = (25+25)/2 = 50/2 = 25
2) Range = 0.18 - 0.11 = 0.07
Mode = 0.15 and 0.16
Number of data = 23
Median =12th term = 0.15
Answer:
The vertex would be (-1, -5).
Step-by-step explanation:
In order to find this, first find the x-coordinate of the vertex. You can do this by calculating out -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(-2)/2(-1)
2/-2
-1
So we know the x-coordinate to be -1. Now we plug that into the equation and find the y value.
-x^2 - 2x - 6
-(-1)^2 - 2(-1) - 6
-(1) + 2 - 6
-5
He had 5 friends to share it the 12 1/2 pounds. 12 1/2 divided into 5 is 2 1/2
Answer: 275 adult tickets and 500 children's tickets were sold.
Step-by-step explanation:
Let a represent the number of adult tickets that were sold.
Let c represent the number of children's tickets that were sold.
The total number of tickets that were sold is 775. It means that
a + c = 775
If adults tickets sold for 2.50 and children’s tickets sold for 1.00 and the total amount was $1187.5, it means that
2.5a + c = 1187.5- - - - - - - - - - -1
substituting a = 775 - c into equation 1, it becomes
2.5(775 - c) + c = 1187.5
1937.5 - 2.5c + c = 1187.5
- 2.5c + c = 1187.5 - 1937.5
- 1.5c = - 750
c = - 750/ - 1.5
c = 500
Substituting c = 500 into a = 775 - c, it becomes
a = 775 - 500
a = 275
