Answer:

D. 3x +y = 23

Step-by-step explanation:

If you know what "standard form" is, then you recognize that only one offered answer choice is actually in standard form. That is the correct choice.

3x + y = 23

_____

Standard form for a linear equation is ...

In a data set with a minimum value of 54.5 and a maximum value of 98.6 with 300 observations, there are 186 points less than 81.

Answer:

81.2 is the 62th percentile

Step-by-step explanation:

What is the interpretation for a percentile?

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

300 observations, there are 186 points less than 81.2. Find the percentile for 81.2.

$p = \frac{186}{300} = 0.62$
