4.6y-y+4=y-1.2
We simplify the equation to the form, which is simple to understand
4.6y-y+4=y-1.2
We move all terms containing y to the left and all other terms to the right.
+4.6y-1y-1y=-1.2-4
We simplify left and right side of the equation.
+2.6y=-5.2
We divide both sides of the equation by 2.6 to get y.
y=-2
1. there is a common difference of 4, so ur next terms are 13,17
2. there is a common difference of -2
3. A(n) = -14 + (n-1) * 2...n = 9
A(9) = -14 + (9-1) * 2
A(9) = -14 + 8 * 2
A(9) = -14 + 16
A(9) = 2
4. f(n) = 3 + 4(n-1)
Answer: 9702
Step-by-step explanation: 154*63=9702
Mean = all numbers added up ÷ amount of numbers
So 22 + 24 + 26 + 20 + 29 + 28 + 26 = 175
175 ÷ 7 = 25 for mean
Median = middle number when arranged in order
20, 22, 24, 26, 26, 28, 29.
Middle number is 26.
Mode = most frequent number
Also 26 because it appears twice whereas all the other numbers only appear once.
Range = highest number - lowest number
29 - 20 = 9.
