Answer:

F(x) = - $\sqrt[3]{x}$

Step-by-step explanation:

A square root can only have a positive input for the domain

(The domain is the input for the function)

The cube root can be either negative or positive as an input

F(x) = - $\sqrt[3]{x}$ can have inputs from negative infinity to infinity

A standard unit of measurement in astronomy is the astronomical unit, or au. it equals is about 150,000,000,000 m. in 2000, pion

Maurinko [17]

First we convert the m to km by dividing the number by 1000. 1000m = 1 km.

150,000,000,000 / 1000 = 150,000,000 km

Now we divide 150,000,000/11,000,000 = 13.6363636364 au.

A scientist claims that 4% of viruses are airborne. If the scientist is accurate, what is the probability that the proportion of

oksano4ka [1.4K]

Answer:

The probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%=0.00427

Step-by-step explanation:

We are given that

$\mu_{\hat{p}}=p=4%=0.04$

n=662

We have to find the probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%.

q=1-p=1-0.04=0.96

$\sigma_{\hat{p}}=\sqrt{p(1-p)/n}$

$\sigma_{\hat{p}}=\sqrt{\frac{0.04(1-0.04)}{662}}$

$\sigma_{\hat{p}}=0.0076$

Now,

$P(\hat{p}>0.06)=1-P(\hat{p}$

$=1-P(\frac{\hat{p}-\mu_{\hat{p}}}{\sigma_{\hat{p}}}$

$=1-P(Z$

$=1-0.99573$

$P(\hat{p}>0.06)=0.00427$

Hence, the probability that the proportion of airborne viruses in a sample of 662 viruses would be greater than 6%=0.00427
