Step-by-step explanation:

Remove the parentheses

3t-2t+2 > 5t-8+4t

t+2 > t-8

Cancel equal terms

2 > -8

The statement is true

PLEASE NOTE:That sign you are putting under this > I didn't put it so just remember to put it.

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

Write the ratio as a fraction in simplest form: 4ft : 2.4ft

Gekata [30.6K]

The answer would be 12:7 . You have to change feet into inches and calculate it from there . Doing that would get you 48:28 and if you put it into simplest form it'd be 12:7 dividing both by 4.
