Charles is helping at a shelter and weighed a group of small dogs. The sample mean weight was 3.1 kg and the sample standard deviation was 2.5 kg. Charles found the deviation of each one of the dog's weight from the sample mean, and calculated the mean and standard deviation bf these deviations. Can you find from those deviations what would be the mean and standard deviation? a) Mean of the deviations: 3.1; standard deviation of the deviations: 2.5

b) Mean of the deviations: 0; standard deviation of the deviations: 1

c) Mean of the deviations: 3.1; standard deviation of the deviations: 1

d) Mean of the deviations: 0; standard deviation of the deviations: 2.5

a ruler? idk

step-by-step explanation:

answer is c

step-by-step explanation:

81/12=324/x

x=48

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
