Lie is solving the quadratic equation by completing the square.

wel

we have

$3x^{2} + 18x - 8 = 0$

Step $1$

Move the constants to the right side

$3x^{2} + 18x = 8$

Step $2$

Factor 3 out of the variable terms

$3(x^{2} + 6x) = 8$

Step $3$

Add $27$ to both sides of the equation

$3(x^{2} + 6x+9) = 8+27$

$3(x^{2} + 6x+9) = 35$

Step $4$

Write the polynomial as a binomial squared

$3(x+3)^{2} = 35$

therefore

the answer is

Factor 3 out of the variable terms.

b. Find and interpret the standard deviation of the number of floors in this data set. Select the correct choice below and fill

Nat2105 [25]

Answer:

Option B. The standard deviation of the number of floors per city is nothing.

Step-by-step explanation:

The standard deviation of a data set is the statistic that measures the deviance or dispersion of the data from the relative mean. In other words, it is is a measure of how spread the numbers are. The standard deviation is given by the following formula:

$\sigma = \sqrt{\frac{1}{N}(x-\mu) ^{2} }$

In this case, it is the deviation of the number of floors in the building in the city.
