Answer: -3n+31
Step-by-step explanation:
1. 28-55=3
25-22=3
22-19=3
19-16=3
This means that n = -3 as we are subtracting
2. We then do the opposite, we take the first number and we add 3 instead of taking it away we get 31.
That is how you get your answer
-3n+31
Answer:
Length of the base=10
Width of the base=50
Step-by-step explanation:
Length of the base=80/8=10
Width of the base= 6.25*8=50
-4/3 x (-3/4)x > -4/3 x (-6)
x > 4 x 2
x > 8
Answer:
5
Step-by-step explanation:
Given :
Observed values = 5, 10, 15
Expected freqencies = 10
χ² = Σ(observed - Expected)² / Expected
χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10
χ² = 25/10 + 0/10 + 25/10
χ² = 2.5 + 0 + 2.5
χ² = 5
I am sure but I am going with Property if equation . this is say if x =2 then 2 x y = 2y .
