what are two methods you can use to find the area of a square. I WILL GIVE BRAINLIEST I NEED HELP QUICKKKKK
Doss [256]

Answer:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9
Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, s^{2} = 1296

Standard deviation, s = √1296

                                   = 36

Standard error, SE = \frac{s}{\sqrt{n} }

                              = \frac{36}{\sqrt{36} }

                              = \frac{36}{6}

                              = 6

Concept

  • Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
  • Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by 's^{2}'
  • Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’
