When a problem asks for f(5), what is it asking for?

Ira Lisetskai [31]3 years ago

Here we have this function f(5)

Suppose the original function was f(x).

Now if we have to find the value of the function f(x) when we are given x=5, then we replace the x by 5.

So the function becomes f(5) at x=5.

For example:

If we have a function,

f(x) = 7x+9

and we are to find value of this function at x=2,

then we replace the x by 2 everywhere in the function,

f(2) = 7(2)+9

So this is how it works.

Answer: When a problem asks for f(5), it is asking for value of the function f(x) when x=5. Option A. is correct choice.

An education firm measures the high school dropout rate as the percentage of 16 to 24 year olds who are not enrolled in school a
posledela

Answer:

The value of the test statistic z = -0.6606

Step-by-step explanation:

From the question we are told that

      The high dropout rate is \mu  = 6.1%  = 0.061

      The  sample size is  n = 1000

       The  number of dropouts x = 56

       The probability of having a dropout in 1000 people  \= x  = \frac{56}{1000}  =  0.056

Now setting up Test Hypothesis

 Null  H_o :  p = 0.061

 Alternative  H_a : p < 0.061        

The Test statistics is mathematically represented as

                 z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }

substituting values

               z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }

               z = -0.6606
