Answer:
, 4.23 , 9/2
Step-by-step explanation:
![\sqrt{17} = 4.1231\\](https://tex.z-dn.net/?f=%5Csqrt%7B17%7D%20%3D%20%204.1231%5C%5C)
9/2 = 4.5
4.23
Answer:
the average of this new list of numbers is 94
Step-by-step explanation:
Hello!
To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96
for the first list
![\frac{a+b+c+80}{4} =90](https://tex.z-dn.net/?f=%5Cfrac%7Ba%2Bb%2Bc%2B80%7D%7B4%7D%20%3D90)
for the new list
![\frac{a+b+c+96}{4} =X](https://tex.z-dn.net/?f=%5Cfrac%7Ba%2Bb%2Bc%2B96%7D%7B4%7D%20%3DX)
To solve this problem consider the following
1.X is the average value of the second list
2. We will assign a Y value to the sum of the numbers a, b, c.
a + b + c = Y to create two new equations
for the first list
![\frac{y+80}{4} =90](https://tex.z-dn.net/?f=%5Cfrac%7By%2B80%7D%7B4%7D%20%3D90)
solving for Y
Y=(90)(4)-80=280
Y=280=a+b+c
for the second list
![\frac{y+96}{4} =X\\](https://tex.z-dn.net/?f=%5Cfrac%7By%2B96%7D%7B4%7D%20%3DX%5C%5C)
![\frac{280+96}{4} =X\\x=94](https://tex.z-dn.net/?f=%5Cfrac%7B280%2B96%7D%7B4%7D%20%3DX%5C%5Cx%3D94)
the average of this new list of numbers is 94
Answer:
<4 = 63°
Step-by-step explanation:
32° + 31° = < 4 ( exterior angle of a triangle is equal to the sum of two opposite interior angles)
<4 = 63°
Hope it will help :)
