What is the standard deviation of 98.21

The unit rate of computers per day is equal to 12 computers per day.

What is a proportional relationship?

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

• y represents the y-variable or total cost​.
• x represents the x-variable or number of computers.
• k is the constant of proportionality.

Next, we would determine the unit rate or constant of proportionality (k) by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 36/3 = 48/4 = 60/5

Constant of proportionality, k = 12.

Therefore, the required linear equation is given by;

y = kx

y = 12x

Answer: a) , b) 0.7975, demand is inelastic, c) increase.

Step-by-step explanation:

Since we have given that

So, derivative w.r.t x would be

As we know that

(b) Find the elasticity when x = 2.

So, we put x = 2, we get that

Since, 0.7975 < 1, so the demand is inelastic.

(c) At $2 per plant, will a small increase in price cause the total revenue to increase or decrease?

The total revenue will also increase with increase in price.

As total revenue =

Hence, a) , b) 0.7975, demand is inelastic, c) increase.

Final answer:

This problem involves the calculation of the elasticity of a demand function using the derivative of the function. The elasticity is then used to analyze the effect on the total revenue when the price changes. The elasticity at a specific point is calculated and used for further analysis.

Explanation:

For part (a), to find the elasticity of the demand function, we need to use the formula for the price elasticity of demand, which is E = (dQ/dX) * (X/Q). Here, dQ/dX is the derivative of the demand function concerning X. This needs to be calculated first. The value of E provides us with the measure of elasticity.

For part (b), when x = 2 we substitute this value into the formula for E to get the elasticity at x = 2.

For part (c), based on the concept of elasticity, if E > 1, the demand is said to be elastic and a price decrease will result in an increase in total revenue, and vice versa. If E < 1, the demand is said to be inelastic and a price decrease will result in a decrease in total revenue, and vice versa. So, after calculating E at x = 2, we can use it to determine the effect on total revenue.

it's .5 or 1/2

Step-by-step explanation:

3/8 ÷ 3/4 = 1/2

Answer:

The wording of this question was really confusing, but I believe the answer is 166 dollars.

Step-by-step explanation:

$220+ $98= $318

650-318=332

332/2=166
