Variance = summation of (x - mean)^2 all divided by the number of dataset.
mean = (17 + 5 + 11 + 1 + 11)/5 = 9

Variance = [(17 - 9)^2 + (5 - 9)^2 + (11 - 9)^2 + (1 - 9)^2 + (11 - 9)^2]/5 = (8^2 + (-4)^2 + 2^2 + (-8)^2 + 2^2}/5 = (64 + 16 + 4 + 64 + 4)/5 = 152/5 = 30.4

sweet [91]

Answer:

The length of the diagonal is 11.879 units

Step-by-step explanation:

On any rectangle or square, any 2 adjacent sides and the diagonal that connects them makes a right triangle. The diagonal is the hypotenuse of that right triangle, and you can find it using the pythagorean theorem:

a^2+b^2=c^2

where a and b are the sides, and c is the diagonal.

\rightarrow8.4^2+8.4^2=c^2\\\rightarrow70.56+70.56=c^2\\\rightarrow c^2=141.12\\\rightarrow c\approx11.879

You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5
Anni [7]

let cat food = x

 total plus 5% = 105% = 1.05

1.05 * (11.50 + X) = 16.80

12.075 + 1.05x = 16.80

1.05x = 16.80-12.075

1.05x = 4.725

x = 4.725 / 1.05

x= 4.50

 the cat food cost $4.50


11.50 +4.50 = 16.00

16.00 * 0.05 = 0.80

16.00 + 0.80 = 16.80
