Answer:

Step-by-step explanation:

This is a right triangle. The floor and the shelf would form a 90 degree angle. The Pythagorean theorem states that the sum of the squares of the legs is equal to the square of the hypotenuse.

8^2+11^2=x^2

185=x^2

x=\sqrt{185}

Answer:

∠M

Step-by-step explanation:

∠M is the only vertex that does not already have an indicated angle. There are three vertexes, being 90° at ∠K (the box-like figure means it is a right angle, therefore 90°) , 61° at ∠N , and ∠M, which does not have a given angle.

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’
