The answer is 16 units
An easy way to find the perimeter is remembering the formula of a+b+c.
So in this case, you count how many units each line of the triangle it covers. 4+6+6= 16

What is the term for a point that varies greatly from all other data points

xenn [34]

The term for a point that varies greatly from all other data points is known as an <u>OUTLIER</u>

<u></u>

Explanation:

An outlier is a data point that differs significantly from other observations. An outlier may be due to variability in the measurement or it may indicate experimental error.
An outlier can cause serious problems in statistical analyses.
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst to decide what will be considered abnormal.
A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier.
The data here appear to come from a linear model with a given slope and variation except for the outlier which appears to have been generated from some other model.
Outliers can occur by chance in any distribution, but they often indicate either measurement error or that the population has a heavy-tailed distribution.

Section a of a theater contains 12 rows of 15 seats each section b contains only 10 rows but had the same number of seats as sec

yuradex [85]

Answer:

15 seats

Step-by-step explanation:

It is given that section A of a theater contains 12 rows of 15 seats each.

Now, it is also given that section B contains only 10 rows it has an equal number of seats the same as section A.

As the number of seats in each row of section A is 15, so, the number of seats in each row of section B will be 15 and the same as section A. (Answer)

1. Gavin and Seiji both worked hard over the summer. Together, they earned a total of $425. Gavin earned $25 more than Seiji. Ho

Gre4nikov [31]

Let x = the amount that Seini earned
Then x + 25 = the amount that Gavin
The amount Gavin earned would also = 425 - x (your directions asked you to have 2 equations.)
Together they earned 425:
x + (x + 25) = 425
2x + 25 = 425
2x = 400
Now divide both sides by 2 to find x.

Use all of this data to satisfy the directions.
