Answer and explanation:
Null hypothesis: p is not 54%
Alternative hypothesis : p is equal 54%
First find standard deviation
Standard deviation is:
σ = √[ P ( 1 - P ) / n ] = √[ 0.54×0.46/220 ] =0.033
The z score is calculated p-P/σ = (0.54-0.50)/0.033 = 1.2121
Therefore we can conclude that proportions are not same and fail to reject the null hypothesis
Answer:
yes, no, no
Step-by-step explanation:
For odd functions : −f(x) = f(−x) for all x
For even functions :f(x) = f(−x) for all x
1) -f(x)= -2x^3 -2x
f(-x) = -2x^3-2x
yes
2 ) f(-x) = 5x^3 -4 ≠ f(x)
no
3 ) f(-x) = -4x -4 ≠ f(x)
no
T he x and y intercepts of the equation:
are : y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
Step-by-step explanation:
we need to identify the x and y intercepts of the equation: 
Finding x-intercept
For finding x-intercept put y=0
We are given the equation:

Solving:

So, x-intercept is (4,0)
Finding y-intercept
For finding y-intercept put x=0
We are given the equation:

Solving:

So, y-intercept is (0,-5)
the x and y intercepts of the equation:
are :y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
