The average annual salary for employees in a store is $50,000. It is given that the population standard deviation is $4,000. Sup

Nadya [2.5K]

Answer: 478

Step-by-step explanation:

The formula to calculate the standard error of the population mean is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ is the standard deviation and 'n' is the sample size.

Given: Mean : $\mu=$\50,000$

Standard deviation : $\sigma= $\4,000$

Sample size : $n=70$

Now, the value of the standard error of the average annual salary is given by :-

$S.E.=\dfrac{50000}{\sqrt{70}}=478.091443734\approx478$

Hence, the standard error of the average annual salary = 478

Pls help 31b&c. ASAP Thx

Leto [7]

Answer:

b. g(x) = 12x+10

c. x = 9/2

Step-by-step explanation:

b. g(2x+1)=6x+4

g(2x+1) = 6(2x+1)+4

g(2x+1) = 12x+6+4

g(2x+1) = 12x+10

g(x) = 12x+10

c. g(x) = 64

12x+10 = 64

12x = 54

x = 54/12

x = 9/2

PLEASE HELP IVE BEEN STUCK ON THIS QUESTION FOR 20 MINS IDK :(

steposvetlana [31]

Remember
$\frac{x^m}{x^n}=x^{m-n}$
and
if $a^b=a^c$ where a=a, then b=c
so
$\frac{7^9}{7^n}=7^{9-n}=7^3$
$7^{9-n}=7^3$
so
9-n=3
-n=-6
n=6

answer is 6
