What is the standard deviation of the following data set rounded to the nearest tenth? 56,78,123,34,67,91,20

Elena L [17]

Answer:

32.2

Step-by-step explanation:

The given data set is:

56,78,123,34,67,91,20

The mean of this data set is

$\frac{56+78+123+34+67+91+20}{7} =\frac{469}{7} =67$

The standard deviation is given by;

$SD=\sqrt{\frac{\sum(x-\bar X)^2}{n} }$

$SD=\sqrt{\frac{(56-67)^2+(78-67)^2+(123-67)^2+(34-67)^2+(67-67)^2+(91-67)^2+(20-67)^2}{7} }$

$SD=\sqrt{\frac{7252}{7} }$

$SD=\sqrt{1036}=32.2$

Determine the gcf. 2y^10, 5y^4, 6y^5

Sonja [21]

Answer:

y^4

Step-by-step explanation:

2y^10, 5y^4, 6y^5

We first need to find the factors of each term

2y^10 = 2*yyyyyyyyyy

5y^4 = 5yyyy

6y^5 = 3*2 yyyyy

The greatest common factor is the largest term that appears in all the terms

The greatest common factor is yyyy = y^4
