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:
x = 5, 2
Step-by-step explanation:
x^2 = 7x - 10
x^2 -7x + 10 = 0
(x - 2)(x - 5) = 0
x = 5, 2
Answer:
(5y+3) x (y-2)
Step-by-step explanation:
5y^2-7y-6
5y^2+3y-10y-6
y(5y+3(-2(5y+3)
(5y+3) x (y-2)
Step 1. Isolate the variable x:
Step 2. Use the simplified inequality to graph:
- Select an OPEN point on x = -5
- Select a ray extending from -5 to positive infinity (GREATER than -5)
I hope this helps!
