Answer:

A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population

swat32

Answer:

Step-by-step explanation:

ore energy entered the Earth system than exited due to the greenhouse effect, solar energy trapping systems like solar panel, etc.

How CO₂ changed the energy in the Earth system due to many reasons:-

Carbon dioxide forces the Earth's energy budget out of balance by absorbing thermal infrared energy radiated by the surface. It absorbs thermal infrared energy with wavelengths in a part of the energy spectrum that other gases, such as water vapor, co₂, etc.

The greenhouse effect also increases energy in the earth's system.

An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat.

These greenhouse gas emissions have increased the greenhouse effect and caused the earth's surface temperature to rise.

Jenny borrowed $500 for five years at 4 percent interest, compounded annually. What is the total amount she will have paid when

Sladkaya [172]

The total amount due in the future (F) for the current loan (P) with compound interest (i) is calculated through the equation,
F = P x (1 + i)^n
where n is the number of years. Substitute to the equation, the values given above,
F = ($500) x (1 + 0.04)^5 = $608.326
Thus, Jenny would pay approximately $608.326.

joja [24]

The side length of the square is a rational.

What is the area of the basement?

Any lower storey of a structure that is partially or completely below the lowest contiguous proposed ground level is referred to as a basement floor, provided that the portion of the storey above ground level does not exceed 75 cm.

Given: Taylor uses tape to mark a square play area in the basement for her daughter.

The area measures 28 ft2.

We know that the area of square is side length square.

As the area measures 28 square feet, so the side length of the square is, 28 feet.

Since 28 is a rational number.

Therefore, the side length of the square is a rational.
