Answer:

standard deviation = 3.0331

Step-by-step explanation:

You can solve for this two different ways.

If you have a TI-84 calculator or something similar, type all the data into list 1. Then click the stat button, then the calc button, then 1-vars stats. This will give you mean, standard deviation, median, mode, etc.

If you are solving by hand, find the different between each data point and the mean. Square these numbers and find the average. Then take the square root of that.

3^2 + 4^2 + 1^2 + 2^2 + 4^2 = 46

46/5 = 9.2

square root of 9.2 = 3.0331

Hope this is helpful!!!!!!!!!!! :)

Phoenix [80]
8 1/2 since 38 1/4= 152/4 and 4 1/2= 9/2, 152/4 divided by 9/2 equals 152/4*2/9=304/36 or 81/2

What is the measure of ∠C in the figure below
sertanlavr [38]

Answer:

C. 56°

Step-by-step explanation:

An isosceles triangle has two sides that are equal. ∆ABC has two equal sides. Thus, the angles opposite the two sides of an isosceles triangle are also congruent to each other.

<C and <A are congruent to each other.

m<A = 56°, therefore,

m<C = 56°
