The common ratio is -1/5.

Each number is the opposite (negative sign) and one fifth of the last one. This means to get the next term, you multiply by -1/5, so that is your common ratio.

Nat2105 [25]

Answer:

The correct option is F.

Step-by-step explanation:

A parameter is a single numerical value describing a certain characteristic of the entire population. It is computed using the population values. For example, population mean, population variance, etc.

A statistic is also a numerical value that defines certain characteristic of a sample. It is computed using the sample values. For example, sample mean, sample variance, etc.

Here the mean score for all the 50 students in the midterm Math exam is computed as 88.

This mean value is a parameter because it is computed using the entire population of 50 students in the math class,i.e. all the population values were included in the calculation of mean 88.

Thus, the correct option is F.

What is the area of a circle?
Andru [333]

The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.

The area can be calculated in terms of known linear measurements of the circle:

-- Area  =  (π) x (radius)²

-- Area  =  (π/4) x (diameter)²

-- Area  =  (1/2) x (circumference) x (radius)

-- Area  =  (1/4) x (circumference) x (diameter)

Any of these formulas will give you the area.  The one you decide to use
just depends on what you already know about the circle.

How might you solve a problem that has both a fraction and a decimal in it
Anni [7]
Well, one way is to convert one of the numbers to the other. For example, if I have 3/5 and 0.5, I could convert 3/5 to a decimal. So, I would have 0.6 (3/5 converted to a decimal), and 0.5. Next, I would just add the two together to get my answer of 1.1
