Expand the equation by multiplying it with itself: (x-3)*(x-3)
x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0
Since this is not part of the choices, try a different approach. Take the square root of both sides:
x - 3 = square root of 5
x - 3 = +/- 2.24
I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.
Answer:
Step-by-step explanation:
Firstly,we need to find the mean, median and mode to enable us know the type of distribution it exhibit.
Mode-data with the highest frequency that is data that has the highest repetition which is 59.
Median-the middle data which is 75.
Mean-average of the data that is addition of the data divided by 25 which gives 75.4 approximately equals to 75
Distribution is unimodal symmetric if it has one clear peak(one mode) and mean = median , so Option A is right
Distribution is skewed left if the mean is less than median and the mode is less than the median that is mean is less than the median, and they are both less than the mode. So option B is wrong.
A distribution is uniform if all outcomes are likely to be the same,it is usually a rectangular shaped distribution. So option C is wrong
A distribution is bimodal if it has two modes. This means that there are two data values that tie for having the highest frequency but as for this data we have only one data with the highest frequency so option D is wrong
Option A is correct
So 1 quater is 25 cents each. 5 quaters would be 125 cents. We know that 4 quaters equal $1.00 So we now have 1 quater left, you can add 25 cents to one dollar and get $1.25
So we started off with 125 cents so we added in a decimal point and added in a dollar sign. Hope this helps.
You got the equation correct
