The historian of a town with about 1900 households conducts a study to determine the average number of years each family has lived in the town. He randomly selects 1012 addresses from property records and observes a mean of 21.2 years and a standard deviation of 5.1 years of residency for those households. A histogram of the data shows a roughly symmetric curve with one peak. The historian cannot use our procedures to conduct inference on the mean number of years residents have lived in this town because the is too large for this population.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?
