The distribution does not represent a probability distribution. The correct option is b.

A probability distribution should satisfy two main conditions: (1) the sum of the probabilities for all possible outcomes should be equal to 1, and (2) the probabilities for each outcome should be between 0 and 1 (inclusive).

In this distribution, the probabilities for the outcomes are 0.3, 0.4, 0.3, and 0.1 for the values of X as 3, 6, 9, and 0, respectively. However, the sum of these probabilities is 1.1, which violates the first condition of a probability distribution.

Therefore, this distribution does not meet the requirements of a probability distribution and is not a valid probability distribution. The correct answer is option b.

1. The functions are the same because each of the function has equations that are modeled after the horse diving into the water.

2. Given t = 20s, so using the equation modeled for Seb, we have

h(20) = -16(20^2) + 16(20) +18

After evaluating it we get -6062ft which is not possible since we cannot get a height in negative and jumping off at a height of 6062ft if it was in positive it wouldn't be done by a sane person.

3. Putting the value of t as 0 in the equation we get,

h(0) = -16(0^2) + 16(0) + 18

After evaluating it, we get 18ft and in this situation, we can say that in 0 seconds that is when the horse had not yet dived, the horse was at a height of 18ft.

4 a. Taking the value of h as 18 in Sabri's equation, we get

18 = -16(t - 0.5)^2 + 22

18 = 16t^2 - 4 + 22            (After solving {t - 0.5}^2)

t^2= 18 + 4 - 22/ 16

t^2= 0

t = 0seconds

b. The maximum height of Sabrina's height was 18ft, since this is the initial height of the horse diving booth.

The probability of a randomly selected quartz time piece having a replacement time less than 9.5 years is 0.0062. The warranty length to cover only 1.2% of the quartz time pieces is approximately 16.6 years.

To find the probability that a randomly selected quartz time piece will have a replacement time less than 9.5 years, we need to calculate the cumulative probability of the normal distribution using the given mean (12.9 years) and standard deviation (1.3 years). Using a standard normal distribution table or a statistical software, we find that the cumulative probability is approximately 0.0062.

To determine the time length of the warranty that covers only 1.2% of the quartz time pieces, we need to find the corresponding value in the normal distribution. This value is the z-score that corresponds to a cumulative probability of 0.012 (1.2%). By looking up the z-score in the standard normal distribution table or using a statistical software, we find that the z-score is approximately -2.08. We can then use the z-score formula (z = (x - μ) / σ) to find the corresponding x-value (time length) by rearranging the formula as x = z * σ + μ. Plugging in the values of z = -2.08, σ = 1.3, and μ = 12.9, we can calculate that the warranty should be approximately 16.6 years.

Answer:

Seven x plus two

Step-by-step explanation:

I think thats whats you wanted, right?

The angles in the parallel lines are as follows:

w = 120°

x = 60°

y = 120°

z = 60°

When parallel lines are cut by a transversal line angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, vertically opposite angles, linear angles, same side interior angles etc.

Let's find the size of x, y, w and z.

Therefore,

w = 120 degrees(vertically opposite angles)

Vertically opposite angles are congruent.

x = 180 - 120 = 60 degrees(Same side interior angles)

Same side interior angles are supplementary.

y = 180 - 60 = 120 degrees(Same side interior angles)

The nominal rate of interest compounded quarterly is the interest rate stated on an investment that is compounded four times per year. To find the nominal rate, we can use the formula for effective interest rate:

(1 + nominal rate/number of compounding periods)^number of compounding periods = (1 + effective rate)

In this case, the effective rate is 6.1%. Let's assume the number of compounding periods is 4 (quarterly compounding). Plugging the values into the formula:

(1 + nominal rate/4)4 = (1 + 0.061)

Simplifying the equation:

(1 + nominal rate/4)4 = 1.061

Taking the fourth root of both sides:

1 + nominal rate/4 = (1.061)(1/4)

Subtracting 1 from both sides:

nominal rate/4 = (1.061)(1/4) - 1

Multiplying both sides by 4:

nominal rate = 4 * ((1.061)(1/4) - 1)

Calculating the value:

nominal rate ≈ 4 * (1.014839 - 1)

nominal rate ≈ 4 * 0.014839

nominal rate ≈ 0.059356 or 5.94%

Therefore, the nominal rate of interest compounded quarterly is approximately 5.94%.

The width of a rectangular computer monitor with a diagonal measurement of 26 inches falls between the integers 36 and 37, so k is 36.

Let the length of the monitor be 3x and the width be 2x, where x is a positive constant.

Using the Pythagorean theorem, we can write:

(3x)^2 + (2x)^2 = 26^2

Simplifying this equation, we get:

13x^2 = 26^2

x^2 = 2 * 13^2

x = 13√2

So the width of the monitor is 2x = 26√2 inches.

To find the integers k and k+1 between which the width of the monitor falls, we can approximate the value of 26√2:

Algebraic reasoning involves using mathematical structures and processes to analyze and solve problems, and it is an important part of mathematical thinking and problem solving.

What is Algebraic expressions.?

An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions can contain one or more variables, which are usually represented by letters, and they can be simplified or evaluated by substituting numerical values for the variables.

For example, the expression "3x + 2y - 5" is an algebraic expression that contains two variables, x and y, and three constants, 3, 2, and 5. The expression can be evaluated or simplified by substituting specific values for the variables. For instance, if we let x = 2 and y = 1, then the expression becomes "3(2) + 2(1) - 5", which simplifies to 3.

A frequency distribution in which high scores are most frequent is said to be positively skewed or right-skewed.

In statistics, skewness refers to the asymmetry of a probability distribution. A frequency distribution is said to be positively skewed or right-skewed if the majority of the data is concentrated on the right side of the distribution, while a few high values are outliers on the right tail. The frequency distribution will look like a graph that is shifted to the right with a longer tail on the right side.

Positive skewness means that the mean (average) of the data will be higher than the median (middle value). The median is a more robust measure of central tendency than the mean in a positively skewed distribution, because it is not influenced by the outliers on the right tail.
