Answer:
20
Step-by-step explanation:
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
The upper quartile for the data set given below is. 14, 8, 23, 9, 11, 27, 22, 3, 17, 12, 29

Ok, first we need to organize.
<span>14, 8, 23, 9, 11, 27, 22, 3, 17, 12, 29
</span>3, 8, 9, 11, 12, 14, 17, 22, 23, 27, 29.
First, we need to find the median, the or the middle, which is 14.
Now that we know the median is fourteen, we take away all numbers to the left of 14, including 14: 17, 22, 23, 27, 29. Now just find the median in this new set of numbers. This will give us our upper quartile, which is 23. Hope this helped, and don't forget to drop a like.
The sum of an angle and its complement =90°
The angle is 59°; its complement is 31°
Step-by-step explanation:
Given measure of an angle is 28 degrees greater than its complement.
By definition the sum of an angle and its complement =90°
Let the angle be x
The angle's complement must be x−28° (from the given information)
x+(x−28°)=90° or ![x+(x−28°)=90°](https://tex.z-dn.net/?f=x%2B%28x%E2%88%9228%C2%B0%29%3D90%C2%B0)
2x= 118° or ![2x= 118°](https://tex.z-dn.net/?f=2x%3D%20118%C2%B0)
x= 59° or ![x= 59°](https://tex.z-dn.net/?f=x%3D%2059%C2%B0)
So the angle is 59° and its complement is 59°−28°=31°
![So the angle is 59° and its complement is 59°−28°=31°](https://tex.z-dn.net/?f=So%20the%20angle%20is%2059%C2%B0%20and%20its%20complement%20is%2059%C2%B0%E2%88%9228%C2%B0%3D31%C2%B0)
