Answer:

The variance is 122.0627 kg

Step-by-step explanation:

The square of the standard deviation of a distribution gives us the variance.

If a random sample of 10 subjects have weights with a standard deviation of 11.0482 kg.

Then the standard deviation is

{ \sigma} = 11.0482

To get the variance, we square both sides to get;

{ \sigma}^{2}  = 11.0482^{2}

This implies that,

{ \sigma}^{2}  = 122.0627kg

Write the standard equation of the circle with the given center is (0,0) and radius is 2.5
BlackZzzverrR [31]

Answer:

x² + y² = 6.25

Step-by-step explanation:

The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.

From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so

( x – 0)² + ( y - 0)² = (2.5)²

x² + y² = (2.5)²

x² + y² = 6.25

A TV is on sale at 30% off for $420. What was the original price of the TV?

<span>"A TV is on sale at 30% off for $420"
 
What was the original price of the TV?
</span>

Well if you start to calculate first off you are sooner or later going to figure out that in order for it to be 420 the answer has to be bigger than 1,000. If you get to 1,200 and calculate 30 percent off of it it the answer is 360 so a ballpark quesstiminate would be to go two more hundredths up. Therefore 30 percent of 1,400 is 420
