Katie solved the equation by completing the square.
emmainna [20.7K]

Katie has equation x^2+12x-7=0 and wants to solve it completing the perfect square. In order to do it, first rewrite 7 in right side:

x^2+12x=7.

Then note that 12x=2\cdot 6\cdot x, so Katie has to add 6^2=36 to both sides (because x^2+12x+36=x^2+2\cdot 6\cdot x+6^2=(x+6)^2):

 x^2+12x+36=7+36,\\ \\(x+6)^2=43.

Answer: correct choice is C.

The heights of a group of sixth graders' are summarized below. If another sixth grader were to be measured, what would be a good
olga nikolaevna [1]

Using the mean, median and mode we can assume that a good prediction for her height would be 55 inches.

In the given data ,

Range of the data is 10. So all the values are between 50 and 60.

mode of the data is 57 , and the mean is 55 and the median is 55

Therefore a random 6th grader can have any value between 50 and 60 since it is the range.

Now the mean and median of the function will be closest to a random value.

Hence of all the options 55 is the most efficient explanation of the central tendency of the dataset .

When the probability density function contains a large number of local maxima, the edge points of a continuous distribution are frequently referred to as the distribution's modes.

Any x value that causes the density function probability of a variate to reach a locally maximum value is often thought of as a mode, making any peak a mode.

The median is the value that divides the top and bottom halves of a large dataset, a demographic, or a probability distribution in statistics and probability theory.

Hence of all the options 55 is the most efficient explanation of the central tendency of the dataset .
