Answer:

2.42

Step-by-step explanation:

standard deviation= sqrt(variance)

Variance=E[X2] - E[X]2

E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81

E[X2] =sum(X2)/n = 189/9 = 170/81

Variance= 476/81

Standard deviation = sqrt(476/81) ~2.42

Triss [41]

Answer:

16.4 feet

Step-by-step explanation:

For a right triangle

sin(x) = \frac{opposite}{hypotenuse}

Since we know the angle and the hypotenuse, we can calculate the opposite side.

\sin(66)=\frac{x}{18}

Multiply each side by 18

18sin(66)=x

x=18sin(66)  

Calculate sin(66)

sin(66)=0.914

18*0.194=16.4

Super ez im just slow plz help<br> -3x+15-6x=30+32x
strojnjashka [21]

Answer:

-15/41

Step-by-step explanation:

-3x + 15 - 6x = 30 + 32x

~Combine like terms

-9x + 15 = 30 + 32x

~Subtract 15 to both sides

-9x = 15 + 32x

~Subtract 32x to both sides

-41x = 15

~Divide -41 to both sides

x = -15/41

Best of Luck!
