George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. he followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24. step 1: find the total cars needed to have a mean of 24: . step 2: find the total cars sold: . step 3: subtract the total cars sold from the total cars needed: . step 4: state the george needs to sell 26 cars next month. where did george make his first mistake? step 1 step 2 step 3 step 4

The answer is: George made his first mistake in Step 1.

Getting a result of 26 cars needed means that he didn't take in consideration the next month in the mean calculation.

We have information of the number of sold cars of the first seven months, but if he wants to calculate the number of cards he needs to have a mean of 24 sold cards next months, he should take in consideration an extra month (the eighth month).

Checking the mistake:

So, it proves that he made a mistake by multiplying it into 7 and instead into 8

The correct answer would be:

He needed to include the eighth month in order to calculate how many cars he should sell next months in order to have a mean of 24 cars.

Have a nice day!

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
