Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094

A= 28
Answer:
1)=4.89897948557
2)=9.79795897113
3)=14
4)=18.3847763109
mark me the brainliest please
The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).
