Answer: -4/5
Step-by-step explanation:
you can use slope formula to solve this question. (Y1-Y2)/(X1-X2). So the answer to this question should be (0-4)/(5-0)= -4/5
Answer:
For this case we need to check the conditions in order to use the normal approximation:
1) 
2) 
Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:

The mean would be given by:

And the deviation is given by:

Step-by-step explanation:
For this case we know the following info:
n =60 represent the sample size
represent the estimated proportion of people that will buy a packet of crackers after tasting
For this case we need to check the conditions in order to use the normal approximation:
1) 
2) 
Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:

And the deviation is given by:

I would try using Photomath or Desmos both great graphing apps!

Answer: They are inverses of each other.
Explanation:
f(x) = -x+5
f(g(x)) = -(g(x)) + 5
f(g(x)) = -(-x+5) + 5
f(g(x)) = x - 5 + 5
f(g(x)) = x
The steps to show that g(f(x)) = x are identical to what is shown above. This is because both f(x) and g(x) are the same.
Since f(g(x)) = x and g(f(x)) = x are true, this means the functions are inverses of each other.
