Ignore the circles. The ratio of stars to squares is simply 5 to 11 .
Answer:
Step-by-step explanation:
(3 + 8)/2 = 11/2
(-1 + -6)/2 = -7/2
(11/2, -7/2)
I'll walk you through the first one, and then you should be able to do the rest.
The first step is to right out your numbers from least to greatest
Problem #1: 2,4,5,6,8,10,13,17,19,20
To find the MEDIAN, you're simply crossing out a number from each end until you meet in the middle. In this case, you have an even number of data, which means once you get to the middle, you're have to find the average.
In this problem, your two middle numbers are 8 & 10. Since only one number can be the median, you add them together, and divide by 2:
8+10=18 18/2=9 < this is your middle, or MEDIAN
Next, your first and third quartiles-- they're the median of the lower half and data, and upper half.
For the lower quartile, find the mean of 2,4,5,6, and 8. again, cross out one from each side until you get to the middle. FIRST QUARTILE = 5
Do the same process for the upper half of data (10,13,17,19 & 20).
THIRD QUARTILE = 17
The MIN is the lowest number of data = 2
The MAX is the highest number of data = 20
Best of luck!

Answer: 1,600 people
Step-by-step explanation:
The survey showed that 40 out of 75 people would vote for Mr. Best.
Convert this figure to a percentage so that you can use it to find out the number of people that would vote for him if numbers were larger:
= 40 / 75
= 53.33%
If 3,000 people voted, 53.33% would vote for Mr. Best which is:
= 3,000 * 53.33%
= 1,599.9
= 1,600 people
