A Ligustrum plant cell is exposed to an aqueous solution having sodium and chloride concentrations higher than the sodium and chloride concentrations of the cell interior. After thirty minutes, a biologist observes the cell under a microscope and states that the cell shows no evidence of having lost water. Which of the following best explains the observation?1The cell membrane is not permeable to either sodium or chloride.2The cell is surrounded by a rigid cell wall.3The cell protected itself by actively transporting sodium across the cell membrane into the external solution.4A plant cell, being different from an animal cell, cannot tolerate high concentrations of sodium and chloride and dies within 5 minutes.5The cell interior contains a variety of solutes in addition to sodium and chloride.

In a certain city of several million people, 7.7% of the adults are unemployed. If a random sample of 300 adults in this city is
Lilit [14]

Answer: 0.2643

Step-by-step explanation:

Given : The proportion of  adults are unemployed : p=0.077

The sample size = 300

By suing normal approximation to the binomial , we have

\mu=np=300\times0.077=23.1

\sigma=\sqrt{np(1-p)}=\sqrt{300\times0.077(1-0.077)}\\\\=4.61749932323\approx4.62

Now, using formula z=\dfrac{x-\mu}{\sigma}, the z-value corresponding to 26 will be :-

z=\dfrac{26-23.1}{4.62}\approx0.63

Using standard distribution table for z , we have

P-value=P(z\geq0.63)=1-P(z

=1-0.7356527=0.2643473\approx0.2643

Hence, the probability that at least 26 in the sample are unemployed  =0.2643

wel
Hey ! 

I am going to explain what I did to get the answer...

I multiplied $29,160 by 30 = $874,800
Then I multiplied $84,460 by 30 = $2,533,800 

Then I subtracted the results = a difference of $1,659,000

So the answer to your question is, $1,659,000 is the difference. 

I hope I was able to help you out :D <span />
