Answer:
The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.
Step-by-step explanation:
We are given that
Mean, 
Standard deviation, 
We have to find the two weights that separate the top 3% and the bottom 3%.
Let x be the weight of machine components
=0.03
From z- table we get
Therefore, we get
Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.
Oh this question is kinda tricky. At first glance it’s 1 : 1.5 but notice the units. The model car is 10 inches long and the actual car is 15 feet long.
I think you know where to go from there, but 15 feet * 12 inches = 180 inches.
10 : 180 simplifies to 1 : 18 inches
Answer:
f^-1 (x)=x^2-4x+1
Step-by-step explanation:
y=sqrt(x+3)+2
x=sqrt(y+3)+2
sqrt(y+3)=x-2
y+3=(x-2)^2
y+3=(x-2)(x-2)
y+3=x^2-2x-2x+4
y+3=x^2-4x+4
y=x^2-4x+4-3
y=x^2-4x+1
Distribute the first +a to the +a and multiply, then multiply the same +a and the +b and then multiply the -b and the +a and then the -b and the +b.
Hope this helped, if you have any more questions about this, just ask.
