The mean of four consecutive even numbers is 15. Enter each number separated by a comma. The numbers are .

12, 14 , 16, 18

Step-by-step explanation:

let the smallest of the numbers be n

since the numbers are consecutive and even, the numbers may be expressed as :

n (n+2) (n+4) (n + 6)

it is given that the mean of the 4 numbers is 15, hence the following formula applies

mean = (sum of all values )  ÷ number of values

it is given that the mean = 15

sum of values = n + (n+2) + (n+4) + (n + 6) = 4n + 12

hence the formula becomes:

15 = (4n+12) / 4

15(4) = 4n + 12

60 = 4n + 12

4n = 60 - 12

4n = 48

n = 48 / 4

n = 12

hence the numbers are

12, 14 , 16, 18

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
