Answer:
The answer is 15x+3 i think........... or its 10x+3/5x
Step-by-step explanation:
The answer is 5.5
The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)
For the population A:
sd₁ = 17.6
n₁ = 25
For the population B:
sd₂ = 21.2
n₂ = 30
Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
= √(17.6²/20 + 21.2²/30)
= √(309.76/20 + 449.44/30)
= √(15.49 + 14.98)
= √(30.47)
= 5.5
Answer:
x° = 50°
Step-by-step explanation:
x° + 130° = 180° (adjacent angles add up to 180°)
x° = 180° - 130°
x° = 50°
X=20
m∠ b=48
m∠ c=40
Show work
6*20-28=92
2*20=40
