a

b

Step-by-step explanation:

From the question we are told that

   The population proportion  is    

   The sample size is n =  50

Generally the mean of this sampling distribution is  

Generally the standard deviation is mathematically represented as

=>    

=>    

Generally the probability that the value of will be between 0.54 and 0.61 is mathematically represented as

=>  

From the z table  the probabilities of  ( Z < -0.4412 ) and (Z <  -1.912 ) is

and  

Generally

Generally the probability that the value of will be greater than 0.71  is mathematically represented as

=>    

From the z table  the probabilities of ( Z >   1.0294  )

So

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
