If line segment AB is 400%, what is the length of a line segment that is 100%?
_____ inch(es)
(Type a whole number or a decimal) ​

Answers

4 divided by 4, equals 1 so that means that 100% out of 400% of the line is equal to 1 inch

If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

from the given diagram, we get,

the line AB = 4 in.

and,  line segment AB is 400%,

now, we have to find the length of a line segment that is 100%.

so, we get,

4 in = 400%

so, 100% = 4/ 400 * 100

               = 1 in.

Hence, If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

It is best to use median as your measure of center when you have an extreme number in your set of data (also known as an outlier).

Answers

Answer:

true

Step-by-step explanation:

The median is generally a better measure of the center when there are extreme values or outliers because it is not affected by the precise numerical values of the outliers. The mean is the most common measure of the center. The words “mean” and “average” are often used interchangeably.

Answer:

mRJN = 75°

Step-by-step explanation:

VJA = 15°

If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°

Angle VJE is supplementary to VJR and therefore also 90°

And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.

Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°
