Answer:
G 328 ft
Step-by-step explanation:
AB = 229.431 ft
AB² + BC² = AC²
229.431² + h² = 400²
h = 327.659 ft ≈ 328 ft

Answer:
(f + g)(x) = 7x - 1
Step-by-step explanation:
Given : f(x) = 5x – 2 and g(x) = 2x + 1
We have to find (f + g)(x)
Consider (f + g)(x) = f(x) + g(x)
Also, given f(x) = 5x – 2 and g(x) = 2x + 1
Substitute, we have,
f(x) + g(x) = 5x - 2 + 2x + 1
Like Terms are terms having same variable with same degree.
Simplify by adding like terms, we have,
f(x) + g(x) = 5x + 2x - 2 + 1
f(x) + g(x) = 7x - 1
Thus, (f + g)(x) = 7x - 1
Given data:
Sample size 
Sample proportion of people support candidate A:
Population proportion of people support Candidate A :
Check the condition: 
and 
Null Hyposthesis: 
Alternative Hypothesis: 
The test statistics:
Plug in p=0.56, P=0.40 and n=100 in the above formula,
The table value of z at 10% of significance level is 1.28
Table value is less than the calculated value.
Hence 
is rejected at 10% level.
Therefore there is the evidence at an alpha level of 10% to conclude that the percentage of people who support candidate A has changed.
I had a seizure trying to understand that question
