How do you find the average of a group of numbers

Mathematics
1 answer:
Iteru [2.4K]3 years ago
7 0

Answer:

You add them together and divide it by how many number there are.

Step-by-step explanation:

For example lets say we need to find the average of 12, 15, 18, and 24.

You would do 12+15+18+24

You will get a sum of 69

Then since there are 4 numbers you do 69 divided by 4 and get a quotients of 17.25.

Therefore 17.25 is the average of all four numbers.

Find the work done by gas?
salantis [7]

The work done by the gas when the gas expands will be 567.65 ft-lb.

<h3>What is the work done for an isothermal process?</h3>

The Pressure is inversely proportional to the volume.

Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.

Then the work done by the gas will be

WD = P₁ V₁ ln (V₂ / V₁)

A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.

The gas expands to a volume of 3 cubic feet.

Then the work done by the gas will be

WD = 700 x 2 x ln (3/2)

WD = 1400 x 0.405

WD = 567.65 ft-lb

The work done by the gas when the gas expands will be 567.65 ft-lb.

More about the work done for isothermal process link is given below.

Please Answer!!!!
Morgarella [4.7K]

Answer:

A). F = \frac{9C}{5}+32

B). 374°F

Step-by-step explanation:

A). Formula to convert the temperature from degree centigrade to °F is,

    C = \frac{5}{9}(F-32)

    We have to solve the formula to get the value of F,

    9 × C = 9\times \frac{5}{9}(F-32)

    9C = 5(F - 32)

    \frac{9C}{5}=\frac{5(F-32)}{5}

    \frac{9C}{5}=(F-32)

    F = \frac{9C}{5}+32

B). In this part we have to find the value of 190° C in °F.

    From the formula given in part (A),

    F = \frac{9\times 190}{5}+32

       = 374°

    Therefore, 190°C = 374°F
