Answer:

**Answer:**

The density curve is symmetric and bell‑shaped.

The normal distribution is a continuous distribution.

Approximately 32% of values fall more than one standard deviation from the mean.

**Step-by-step explanation:**

Lets take a look at each statement.

**The density curve is symmetric and bell‑shaped.**

True.

**The normal distribution is a continuous distribution.**

True, the value of the measure can be a decimal number, like 10.5, for example.

**The normal distribution is a discrete distribution.**

False. Either the distribution is continuous, or it is discrete. In this case, it is continuous.

**The density curve is a flat line extending from the minimum value to the maximum value.**

False. This statements describes the uniform probability distribution.

**Approximately 32% of values fall more than one standard deviation from the mean.**

True. 68% are within 1 standard deviation of the mean and 32% are more than one standard deviation from the mean.

**Two parameters define a normal distribution—the median and the range.**

False. It is the mean and the standard deviation.

**Step-by-step explanation:**

(b) Find the elasticity when x = 2.

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

**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.**

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.

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.

Solve: x - 1 < 3

x < 4

given x - 1 < 3 ( add 1 to both sides )

x < 4

(2x^5 + 3y^4)(-4x^2 + 9y^4)

Answer:

A. -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸

Step-by-step explanation:

Given:

(2x⁵ + 3y⁴)(-4x² + 9y⁴)

Required:

Find an equivalent polynomial

Solution:

(2x⁵ + 3y⁴)(-4x² + 9y⁴)

Using distributive property of multiplication

2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)

-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸

There are no like terms to add or combine, therefore:

(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸

**Answer:**

-8x^7 + 18x^5y^5 - 12x^2y^4 + 27y^8

**Answer:**

**-45.**

**Step-by-step explanation:**

I am assuming you mean

√25 - 2(3 +4(-2))^2

= 5 - 2(3-8)^2

= 5 - 2 * (-5)^2

= 5 - 2*25

= -45.
