8 0

Step-by-step explanation:

{2}^{4n}  \times  {2}^{2n}  = 512

{2}^{4n}  \times  {2}^{2n}  =  {2}^{9}

{2}^{4n + 2n}  =  {2}^{9}

6n = 9

n  = \frac{3}{2}

Alice knows that 70% of the creatures in Wonderland are anthropomorphic animals. She randomly invites several of Wonderland’s in
Setler [38]

Answer: 0.0084

Step-by-step explanation:

Let p be the population proportion of the creatures in Wonderland are anthropomorphic animals.

As per given, p = 0.70

Sample size : n=120

Let \hat{p} be the sample proportion of the creatures are anthropomorphic animals.

Now, required probability :  

P(\hat{p}>0.80)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.80-0.70}{\sqrt{\dfrac{0.70\times (1-0.70)}{120}}})\\\\P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.10}{\sqrt{\dfrac{0.70\times 30}{120}}})\\\\ =P(Z>\dfrac{0.10}{\sqrt{0.00175}})\ \ \ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\ =P(Z>\dfrac{0.10}{0.04183})\\\\\=P(Z>2.39)\\\\=1-P(Z\leq2.39)\\\\=1- 0.9916= 0.0084

Hence, the probability that more than 80% of the sampled inhabitants are animals= 0.0084

bixtya [17]

Assets are the resources owned by any individual or organization. Svenson's assets increased by $1,400.

<h3>What is an asset?</h3>

An asset is any resource that is been owned by a company, organization, or individual.

Given to us

The original price of the refrigerator is $2,300.

The Market price of the refrigerator is $1,900.

Svensons' paid $500

As it is given to us that the Market price of the refrigerator is $1,400 and as the Svenson's has bought the refrigerator, therefore, this resource(refrigerator) is now owned by the Svenson.

We know that the down payment made is also made from our assets(cash). therefore, the assets increased by $1,400($1900-$500)only.

Thus, the Svensons’ assets increased by $1,400.
