Find the median of the following data set 1,1,2,4,6,7,7,8,9,10,12,13,17,17,18

Answer:
9/10 or 9.5
Step-by-step explanation:
median means middle make sure there in order from least to greatest before solving. then cross one from each side out until you have 1 or 2 left in the middle. in this case the median would be 9/10 or 9.5
The correct answer for the question that is being presented above is this one: "B. 180° counterclockwise rotation around point F." The pre-image ABCDE transformed to create image AꞌBꞌCꞌDꞌEꞌ is that <span>180° counterclockwise rotation around point F</span>
The mean is the average. You calculate it by adding all the numbers up in the data set and divide by how many numbers there are in the data set.
So:
Judging by the first and last points (0, 65), (8, 21), the slope is about -44/8 = -5.5 and the y-intercept is about 65.
The 4th selection is appropriate.
Answer:
350 students
Step-by-step explanation:
Let:
a = number of adults attending
s = number of students attending
a + s = 950 (1) (given)
9a + 6.5s = 7675 (2) (cost per adult * number of adults + cost per student * number of students = total amount spent)
Looking for s. Multiply (1) by 9 then subtract eq (2), this will eliminate the variable a:
(1) 9a + 9s = 8550
- (2) 9a + 6.5s = 7675
-------------------------------
0a + 2.5s = 875
s = 875/2.5 = 350 students
