Answer:

Step-by-step explanation:

A)

these are the intervals of people who are at least adults and are mature enough to take the survey seriously and answer correctly.

B)

You can say with 95 percent certain of the real mean of the population, but you acknowledge that due to difficulties such as, sampling error, real-life problems such as bad weather, bad vision of the surveyed, not knowing the language and due to bad wording, your answers are unsure is the range  of 8 percent due the fluctuation of data caused by bad circumstances.

C)

I believe there should be a quota of 50 to 50 percent to make the data the most equal, though I understand that there may not be an equal distribution of land and cell lines among the U.S. mature populace.

D)

(Since I don't have the data, I can't answer part 4)

During a period of 80 minutes, a music station played 8 minutes of commercials. What is the ratio of music they played to commer
igomit [66]

Answer:

Step-by-step explanation:

80 minutes.......8 minutes played commercials....that means (80 - 8) = 72 minutes played music

so the ratio of music to commercials is : 72/8 which reduces to 9/1...so the ratio is 9:1 <=== ur answer

** pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72....ratio would be 1:9

The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450

A gazelle runs 780 feet in 12 seconds. Angela wants to determine how far a gazelle could run in 1 minute at this rate. Explain h
Hitman42 [59]

Answer:

In 1 min a gazelle runs 3,900 ft.

As a fraction, 1/65

In order to find the solution to this problem you could use a table.

Since we are using seconds we have to convert the 1 min = 60 seconds.

<u>Sec</u><u>   |  12    |    60</u>

<u>Fts</u><u>    |  780  |    x  </u>

12 goes into 60 5 times, so we have to multiply 780 by 5 which gives us 3900.

x=3900
