HELP PLEASE ASAP!!!

Mathematics
1 answer:
natulia [17]2 years ago
7 0

Answer:

Step-by-step explanation:

f(x)=3x-2

f(2)=3(2)-2

f(2)=6-2

f(2)=4

When you solve f(x) for x=2, you get f(2)=4. This means that g(f(2)) is equal to g(4). Now, you can solve g(x) for x=4.

g(4)=4^2-5

g(4)=16-5

g(4)=11

g(f(2))=11

So the answer is A, 11.

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00
ss7ja [257]

Answer:

The test statistics is   z = -1  

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  100

  The null hypothesis  is  H_o : \mu = \$30000

   The alternative hypothesis is  H_a  :  \mu  < \$ 30000

   The sample mean is  \= x  = \$29,750

    The standard deviation is  \sigma  = \$2,500

    The level of significance is  \alpha =0.05

Generally the test statistics is mathematically represented as

        z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }

=>      z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }

=>      z = -1
