The mean per capita income is 15,451 dollars per annum with a variance of 298,116. What is the probability that the sample mean

docker41 [41]

Answer: 0.5467

Step-by-step explanation:

Let X be the random variable that represents the income (in dollars) of a randomly selected person.

Given : $\mu=15451$

$\sigma^2=298116\\\\\Rightarrow\ \sigma=\sqrt{298116}=546$

Sample size : n=350

z-score : $\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

To find the probability that the sample mean would differ from the true mean by less than 22 dollars, the interval will be

$\mu-22,\ \mu+22\\\\=15,451 -22,\ 15,451 +22\\\\=15429,\ 15473$

For x=15429

$z=\dfrac{15429-15451}{\dfrac{546}{\sqrt{350}}}\approx-0.75$

For x=15473

$z=\dfrac{15473-15451}{\dfrac{546}{\sqrt{350}}}\approx0.75$

The required probability :-

$P(15429$

Hence, the required probability is 0.5467.

The function F is defined by f(x)=x^2-5x+6. What is the value of f(4)?

Genrish500 [490]

$f(x)=x^2-5x+6$

↝ f(4) equals to substituting x = 4 in the equation.

Thus,

$f(4)=4^2-5(4)+6\\f(4)=16-20+6\\f(4)=22-20\\f(4)=2$

Therefore, f(4) = 2

Given the parent function f(x)= log10^x and g(x)= 5x-2, what is f(x) • g(x)?

olchik [2.2K]

Answer:

$5x \log_{10}(x)-2 \log_{10}(x)$

(If that closed circle is an open circle, please let me know because that means something totally different)

Step-by-step explanation:

I think you are given:

$f(x)=\log_{10}(x) \text{ and } g(x)=5x-2$

and that you are asked to find:

$f(x) \cdot g(x)$

That operation means multiplication. (Let me know if is an open circle because that means something difference).

$f(x) \cdot g(x)$

$(\log_{10}(x) \cdot (5x-2)$

Distribute:

$\log_{10}(x)(5x)-\log_{10}(x)(2)$

Reorder a little (commutative property):

$5x \log_{10}(x)-2 \log_{10}(x)$
