Answer:
47
Step-by-step explanation:
1. #2 and #3 reveal that it must be between 31 to 89
2. #4 and #5 reveals that the answer is one of these numbers:
44, 45, 46, 47, 48, 49
64, 65, 66, 67, 68, 69
84, 85, 86, 87, 88, 89
This is because only 4, 6, and 8 are divisible by 2
3. You must add up all the numbers to see which ones add up to either 11 or 12.
4 + 7 = 11
4 + 8 = 12
6 + 5 = 11
6 + 6 = 12
8 + 4 = 12
This means that these are the following numbers: 47, 48, 65, 66, 84
4. #7 says that you must find the smallest number. The smallest number left is 47.
It's a ball, so we don't have to worry about friction. Wouldn't it just be 22.6sin(39) = 14.22 pounds of force? Conceptually, at an angle 0 (flat), we would need 22.6sin(0) = 0 pounds of force, and at angle 90 (vertical), we would need 22.6sin(90) = 22.6 pounds (all of it). So it should be 14.22 pounds. And since this is a mathematical question, rather than physics, I'm assuming you don't need to convert to newtons or anything.
The solution to the two functions is (1, 3) and it represents the temperature at which the number of people visiting the zoo equals the number of people leaving the zoo.
Step-by-step explanation:
4x + 4 - 7x =
4x - 7x + 4 =
-3x + 4
{8, 15, 9, 18, 9, 17, 22, 10, 11, 9, 13}<br>
What is the interquartile range of the data set?
8_murik_8 [283]
Answer:
IQR = 8
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
We require the data arranged in ascending order and to find the median Q₂
The median is the middle value of the data arranged in ascending order.
8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22
↑ Q₂
The upper quartile is the middle value of the data to the right of the median
13, 15, 17, 18, 22
↑ Q₃
The lower quartile is the middle value of the data to the left of the median
8, 9, 9, 9, 10
↑ Q₁
IQR = Q₃ - Q₁ = 17 - 9 = 8
