What is the mean of this population? The sum of all the
messages sent by the students is 384
Calculate the mean number of texts sent by a student
on the given day. (Round your answer to the nearest
whole number.)

the answer is 15

Step-by-step explanation:

i just took it and got it right and you would just have to divide 384 by the how many numbers are in the chart thingie which is 25 numbers or little square thingies and you get 15, also i’m really sorry because the way i explained it is probably confusing i tried my best and hopefully i’ve helped you luv

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

lockers 1, 4, 9, 16, 25, 40, and 49 are open
