Answer:

b. 25 in

Step-by-step explanation:

the lateral area is the area of the outside walls (not including the base area).

on a square pyramid there are 4 such outside walls in the form of triangles.

so, each such triangle has an area of 800/4 = 200 in².

the area of a triangle is

baseline × height / 2

the slant height is the height of a wall triangle (not the inner height of the pyramid).

a base edge is nothing else but the baseline of such a wall triangle.

so, we have

200 = baseline × 16 / 2 = baseline × 8

baseline = 200/8 = 25 in

No, The limit of f(x) does not exist as x goes to 0.

Limit: It is asserted that the left hand limit and the right hand limit of a function f(x) exist at a point and are equivalent to one another.

Continuity: If the limit of a function exists at a given location and is equal to the value of the function there, the function is said to be continuous at that place.

Differentiability: If a function is continuous at that moment, it is differentiable. Although essential, this is not a sufficient condition.

Let f(x) = 2x^3 + 2 and g(x) = x^3 - 2.

Then, the expression can be written as:

f(x)/g(x) = (2x^3 + 2)/(x^3 - 2)

So, the expression is a composition of the two non-identity functions f and g, written as:

Step-by-step explanation:

first I calculated 75÷1.25 then subtracted the fare which is 5.25

Answer: False

Step-by-step explanation: False. Linearity is a property of a mathematical model or equation, not of the residuals of that model. In general, the residuals of a model should be randomly dispersed across the values of a predictor variable if the model is a good fit for the data, but this is not a justification for linearity. Linearity refers to the relationship between the predictor and response variables in a model, and whether that relationship can be adequately represented by a straight line.

The area under the standard normal curve to the left of z = 2.06 is approximately 0.9803.

The normal distribution function, also known as the Gaussian distribution or bell curve, is a probability distribution that is symmetric, bell-shaped, and continuous. It is defined by two parameters: the mean (μ) and the standard deviation (σ).

The normal distribution is widely used in statistics and probability theory due to its many desirable properties and its applicability to various natural phenomena. It serves as a fundamental distribution for many statistical methods, hypothesis testing, confidence intervals, and modeling real-world phenomena.

To find the area under the standard normal curve to the left of z = 2.06, you can use a standard normal distribution table or a calculator with a normal distribution function. The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

Using a standard normal distribution table, the area to the left of z = 2.06 can be found by looking up the corresponding value in the table. However, since the standard normal distribution table typically provides values for z-scores up to 3.49, we can approximate the area using the available values.

The closest value in the standard normal distribution table to 2.06 is 2.05. The corresponding area to the left of z = 2.05 is 0.9798. This means that approximately 97.98% of the area under the standard normal curve lies to the left of z = 2.05.

Since z = 2.06 is slightly larger than 2.05, the area to the left of z = 2.06 will be slightly larger than 0.9798.

Therefore, rounding the answer to four decimal places, the area under the standard normal curve to the left of z = 2.06 is approximately 0.9803.

Throwing a coin until it lands tails is an example of a discrete random variable which does not have a finite expectation.

For the given question,

A discrete random variable is a type of variable whose value depends upon the numerical outcomes of a certain random phenomenon. Discrete random variables are always whole numbers, which are easily countable.

It is a variable that can take on a finite number of distinct values and takes numerous values. It is also known as a stochastic variable. When you consider probabilistic experiments with infinite outcomes, it is easy to find random variables with an infinite expected value.

Let X be a random variable that is equal to 2ⁿ with probability 2⁻ⁿ (for positive integer n). Then,

\(E(X)=\sum_{n:1}^{\infty} |2^{-n}2^{n}|\)

⇒ \(E(X)=\sum_{n:1}^{\infty} (1)\)

⇒ \(E(X)=\infty\)

Consider the following example,

You throw a coin until it lands tails.

Let n be the number of heads

Then number of heads can be found by, 2ⁿ

Now, the expected value function is

\(E(X)=\frac{1}{2}(2^{0} )+ \frac{1}{4}(2^{1} )+....\)

⇒ \(E(X)=\sum_{n:1}^{\infty} |2^{-n}2^{n-1}|\)

⇒ \(E(X)=\sum_{n:1}^{\infty} \frac{1}{2}\)

⇒ \(E(X)=\infty\)

Since the number of outcomes is infinite. The probability of each outcome decreases exponentially.

Hence we can conclude that throwing a coin until it lands tails is an example of a discrete random variable which does not have a finite expectation.

Troy will pay $105 for the tennis racquet after a 50% discount.

Here are a few possible ways to draw the contents of the pencil box, assuming there are 12 pencils in total:

Option 1:

6 black pencils, 2 red pencils, 4 green pencils

Option 2:

3 black pencils, 3 red pencils, 6 green pencils

Option 3:

9 black pencils, 3 red pencils

To find out how much Troy will pay for the tennis racquet after a 50% discount, we can use the formula:

Discounted price = Original price - (Discount percent / 100) * Original price

Plugging in the values, we get:

Discounted price = $210 - (50 / 100) * $210

Discounted price = $210 - $105

Discounted price = $105

Therefore, Troy will pay $105 for the tennis racquet after a 50% discount.

By answering the presented question, we may conclude that So Christian  equation spelled 16 words correctly, Sarah spelled 3x - 2 = 46 words correctly, and Leonard spelled 2x + 1 = 33 words correctly.

What is equation?

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilized in many different areas of mathematics, such as algebra, calculus, and geometry. Let's start by defining some variables to represent the number of words each student spelled correctly:

Let x be the number of words Christian spelled.

x + (3x - 2) + (2x + 1) = 95

6x - 1 = 95

6x = 96

x = 16

So Christian spelled 16 words correctly, Sarah spelled 3x - 2 = 46 words correctly, and Leonard spelled 2x + 1 = 33 words correctly.

Interest is the amount of money earned on an account.

Compound Interest

Interest rate is the percentage at which the account earns interest. For this account, the interest rate is 3.4%. Compound interest is when the amount of interest made increases over time. In the question, we are told that the interest on the account is compounded once every year. This means that the amount of interest earned increases once a year. We can use a compound interest formula to solve for the balance in the account in 5 years.

Solving Compound Interest

The compound interest formula is:

In this formula, P is the principal (initial investment), r is the interest rate in decimal form, n is the number of times compounded per year, and t is the time in years. Now, we can plug in the information we know and solve for the final balance.

This means that after 5 years, the balance in the account will be $17,449.27.
