What is the equation of a line through point (-4,5) that is perpendicular to the line with equation y=-6x+4?
Jobisdone [24]
To find the gradient of the perpendicular line, we know that we must do the negative inverse of the current line's gradient

-6x from the old line will now be 1/6x

we are given points on that line and we therefore use the points and the new gradient to find the equation of the line using this formula

y-y1=m(x-x1) where m is the gradient

input the values that we have

y-5=1/6(x--4)

rearrange

y-5=1/6(x+4)
y-5=1/6x+4/6
6y-30=x+4
6y=x+34
y=1/6x+34/6
y=1/6x+17/3

Unaware that 35% of the 10,000 voters in his constituency support him, a politician decides to estimate his political strength.
KatRina [158]

Answer.

a. Population is the total number of voters in the constituency, that is 10000

b. the parameter is the unknown character of the population, that is 35% of 10000= 3,500

c. Statistics of interest is know character from the sample, that is 40% of 200= 80

d. The two answers are not surprisingly, because the sample is a portion of the population and we expect it to be smaller that the population. Thus, parameter must be bigger than statistics of interest.

d) ii. If another 200 sample was to be taken, we expect to see an increase in a statistics of interest.

Thus my answer, please help by your approval as fast as you can
