<u>Answer:</u>
<h2>
h(x) = 2x²+2x-3</h2>
<u>Steps:</u>
f(x) = 3x²+7x-4
g(x) = x²-5x+1
h(x) = f(x) - g(x)
h(x) = 3x²+7x-4 - x²-5x+1
h(x) = 3x²-x²+7x-5x-4+1
h(x) = 2x²+2x-3
Answer:
Median- is 2 because the median is the middle number, you only have 5 numbers so the middle number would be (2)

Answer:
percentage of lightbulb replacement requests = 34.15 %
Step-by-step explanation:
According to Empirical Rule
interval %
μ ± σ 55 ± 4 ( 51 ; 59 ) 68.3
As the question is a percentage between 55 and 51
or between 51 and μ - σ by symmetry is 68.3/2
% of lightbulb replacement requests = 34.15 %
