Answer:

82.5% Americans owned a TV also owned a DVD player .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

Of the 114.2 million Americans who owned a TV, 94.2 million also owned a DVD player.

Here

Part value = 94.2 million

Total value = 114.2 million

Putting all the values in the formula

Percentage = \frac{94.2\times 100}{114.2}

Percentage = \frac{94200\times 10}{1142\times 10}

Percentage = \frac{942000}{11420}

Percentage = 82.5 %

Therefore 82.5% Americans owned a TV also owned a DVD player .

Aleks04 [339]

1500 people subscribed Sunday edition and 250 people subscribed only sunday edition.

<u>Solution:</u>

Given, A survey of 2500 subscribers to a certain news paper revealed that 2250 people subscribe to the daily morning edition  

And 1250 subscribe to both the daily and the sunday editions.  

We have to find how many subscribe to the Sunday edition? how many subscribe to the Sunday edition only?

Let x denote the number who subscribe to the Sunday edition.  

Then the addition rule with overlap tells us that  

Those who subscribe daily edition + those who subscribe sunday edition - those who subscribe both daily and sunday edition = total subscribers in survey

2250 + x – 1250 = 2500

1000 + x = 2500  

x = 1500  

so, 1500 subscribe to the Sunday edition and 1500 – 1250 = 250 subscribe to the Sunday edition only.

Hence, 1500 people subscribed Sunday edition and 250 people subscribed only sunday edition.

I’m sure this is easy but i'm gonna ask anyway
Arada [10]
No, it's always okay to ask if you don't understand a question.  Anyway, for this problem, we just have to plug in the value for <em>V </em>to solve for <em>P</em> :

P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}

A number to the power of 1/3 is the same as taking a cube root.

P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20

The perimeter of one face of the cube is 20m.
