X^2 - 18x + 81 = 0
x^2 - 9x - 9x + 81 = 0
x(x - 9) - 9(x - 9) = 0
(x - 9)(x - 9) = 0
(x - 9)^2 = 0
x - 9 = 0
x = 9

What is the product of 1 1/2 and -1 1/4?
Savatey [412]

positive number times negative number is negative number "(+)(-) = (-)".

1\dfrac{1}{2}\cdot\left(-1\dfrac{1}{4}\right)=-\left(1\dfrac{1}{2}\cdot1\dfrac{1}{4}\right)

we change the mixed numbers to the improper fractions

=-\left(\dfrac{1\cdot2+1}{2}\cdot\dfrac{1\cdot4+1}{4}\right)=-\left(\dfrac{3}{2}\cdot\dfrac{5}{4}\right)=-\dfrac{3\cdot5}{2\cdot4}=-\dfrac{15}{8}=-1\dfrac{7}{8}

Step-by-step explanation:

From the question we are told that:

Sample mean 1 \=x_1=$9

Sample mean 1 \=x_2=$8

Sample standard deviation 1 \sigma_1 = $2

Sample standard deviation 1 \sigma_2 = $1

Generally the equation for Point estimate is mathematically given by

E(x)=\=x_1-\=x_2

E(x)=9-8
