Calculate the variance of the following set of data. 3, 33, 303, 233, 3, 73, 83, 63

andrew-mc [135]

Answer:

12083.929

Step-by-step explanation:

First step: find the mean of the data.

mean = 3+33+303+233+3+73+83+63

= 794

= 99.25

Second step: Now we calculate each dog's difference from the Mean.

Example : 3–99.25=96.25

Answer: (-96.25)+(-66.25)+203.75+133.75+(-96.25)+(-26.25)+(-16.25)+(36.25)

Third step: To calculate the Variance, take each difference, square it, and then average the result.

s² = (-96.25)²+(-66.25)²+203.75²+133.75²+(-96.25)²+(-26.25)²+(-16.25)²+(36.25)²

8–1

= 9264.063+4389.063+41514.063+17889.063+9264.063+689.063+264.063+1314.063

= 84587.5

= 12083.929

Variance Formula:

Variance = s² =Σ(xi− x )²

HELP ASAP PLEASE Find the area of each figure.

liraira [26]

Answer: top triangle = 10 x 4 = 40cm^2 / 2 = 20cm^2

Rectangle = 10 x 6 = 60cm^2

Right hand triangle = 6 x 4 = 24cm^2 / 2 = 12cm^2

Step-by-step explanation:

For top triangle we do 10 - 6 to get shortest side

Rectangle - ignore 14 and use top 10 cm

Finally triangle on right hand - do 14cm - 10 to get base side. Base side is 4cm.

Formula for area of triangle = b x h / 2

Note: ^2 is just to the power of 2 or squared

I hope u found this answer beneficial.

Have a nice day and Christmas holidays m8 :-)
