Answer:
the mean and standard deviation is 2300 and 100 respectively
Step-by-step explanation:
Given that
Mean = 2300
Standard deviation = 500
let us assume the x be the mean of living space
And, the sample is of 25 homes
We need to find out the mean and the standard deviation
So here mean = 2300
And, the standard deviation
= 500 ÷√25
= 500 ÷ 5
= 100
hence, the mean and standard deviation is 2300 and 100 respectively

Answer:
the one with the blue dot is correct.
Step-by-step explanation:
because when you dilate the triangle you increase it and in this case if you do it ABC ~ADE
(2x-3y)(2x-3y)
4x^2 - 6xy - 6xy + 9y^2
4x^2 + 9y^2 -12xy
Solution is 4x^2 = 9y^2 -12xy
