What is the standard deviation of this data set? Use a calculator to help you.

ale4655 [162]

Answer:

Standard deviation = 14.064

Step-by-step explanation:

We are given the following data;

X X - $Xbar$ $(X-Xbar)^{2}$

20 20 - 46 = -26 676

23 23 - 46 = - 23 529

32 32 - 46 = -14 196

36 36 - 46 = -10 100

41 41 - 46 = -5 25

43 43 - 46 = -3 9

44 44 - 46 = -2 4

45 45 - 46 = -1 1

47 47 - 46 = 1 1

54 54 - 46 = 8 64

55 55 - 46 = 9 81

59 59 - 46 = 13 169

61 61 - 46 = 15 225

63 63 - 46 = 17 289

66 66 - 46 = 20 <u> 400 </u>

$\sum(X-Xbar)^{2}$ <u>= 2769 </u>

Firstly we will calculate Mean, $Xbar$ = $\frac{\sum X}{n}$

$Xbar = \frac{20+ 23+ 32+ 36+ 41+ 43+ 44+ 45+ 47+ 54+ 55+ 59+ 61+ 63+ 66}{15}$ = 45.93 ≈ 46

Now, Standard deviation formula is given by;

s = $\sqrt{\frac{ \sum(X-Xbar)^{2}}{n-1}}$ = $\sqrt{\frac{ 2769}{15-1}}$ = 14.064 .

Find the solution set of this system:

bezimeni [28]

Answer:

(−4, 12), (1, −3)

Step-by-step explanation:

y = −3x

x^2 −4 = y

so

x^2 −4 = −3x

x^2 + 3x - 4 = 0

(x + 4)(x - 1) = 0

x + 4 = 0; x = -4

x - 1 = 0; x = 1

when x = 1, y = -3(1) = -3

when x = -4, y = -3(-4) = 12

Answer

(-4 , 12), (1 , -3)
