Answer:

14

Step-by-step explanation:

Given the data:

13 15 14 16 12

The point estimate of the population mean will be :

ΣX/ n

X = Given data points

N = sample size

ΣX = (13 + 15 + 14 + 16 + 12) = 70

N = 5

Hence,

ΣX/ N = 70 / 5

Point estimate of population mean = 14

The larger of two numbers is 2 more than 4 times the other. Their sum is 33. Find the two numbers. How do I answer this?
tia_tia [17]
So, basically. The value of one of the numbers we will call x, and the value of the other number based off of x is 4x+2. So, add these two "numbers" up, and you get 5x+2. Youre equation is: 5x+2=33, 5x=31, x=6.2. So, one number is 6.2, and the other is 26.8

Jay has an album that holds 600 coins. Each page of the album holds 6 coins. If ​39% of the album is​ empty, how many pages are
Nutka1998 [239]

9514 1404 393

Answer:

  61

Step-by-step explanation:

If there are 6 coins on each page, then the number of pages for 600 coins is ...

  (600 coins)/(6 coins/page) = 100 pages

__

If 39% are empty, then 100% -39% = 61% are filled.

The number of filled pages is ...

  61% × 100 = 61/100 × 100 = 61 . . . . pages filled

_____

<em>Comment about percent</em>

You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100

("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)
