Mean: average of all the numbers, in other words all the numbers added together then divide by the amount of numbers
Median:number with a value in the middle
Mode: most common number
Range: the difference in the numbers

Let x be the mean x=(0+3+3+4+4+4+6+8+8+9+10+10+
10+12+14)/15
=x=105/7
x=7

Median can be found by writing every number in order from least to greatest than finding the one in the middle
the median for this set of data is 8

Mode is 4 and 10 since they occur the most

And for range subtract the highest number by the lowest

If on a scale drawing 15 feet are represented by 10 inches, then a scale of 1/10 inch represents how many feet?

Answers

Answer:

* A scale 1/10 inches represents 0.15 feet

Step-by-step explanation:

The ratio is 15 ft:10 in. so you want 1/10 of both. 1/10 of 10 is 1 and 1/10 of 15 is 1.5. One inch on the drawing is 1.5 inches. Now you want to find 1/10 inch as it says, so 0.1 inches: 0.15 feet. You don’t have to complete the problem this way, it’s just how I did it.

What are transformations?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Given:

Line segment MN is graphed in the first and second quadrants of a coordinate plane. The segment is translated 2 units up, then reflected across the y -axis.

According to given question we have

when it is translated 2 units up it is only moving on the y-axis and not the x-axis. But when it is reflected over the y-axis the endpoints flip and become the opposite values.

The line segment is only being translated and reflected it would still maintain its length.

Length remain the same as the original line segment.

Therefore, the required Length of the image is always the same as the original line segment.
