So,the value of the 30th percentile of the given data will be =P30=4

The cumulative distribution function of a real-valued random variable X, or simply the distribution function of X, assessed at x, is the likelihood that X will have a value less than or equal to x in probability theory and statistics.

Using the Cumulative Distribution Function to Calculate Probabilities

F(x) is a cumulative distribution function that calculates the likelihood that the random variable X is smaller than or equal to x:

To get the cumulative probability that X is less than or equal to 1, multiply P(X=0) by P(X = 0) by (P=1):

First, we will determine the value of the cumulative probability P(X<=x):

x         f(x)       P(X<=x)

1       0.02          0.02

2       0.01          0.03

3       0.2          0.23

4       0.17           0.4

5       0.39           0.79

6       0.2           0.99

7 0.01 1

30th percentile will be the x value,

below which less than or equal to 30% of the data falls.

Slope= - 1/2

Step-by-step explanation:

The line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have data shown in the table:

To find the line of best fit, we will calculate its slope and y-intercept.

We know the slope is given by:

\(\rm m = \dfrac{n\sum xy-\sum x \sum y}{n \sum x^2 - (\sum x)^2}\)   where n = 5

After calculating, we get,

\(\rm n\sum xy-\sum x \sum y = 105000\)  and

\(\rm n \sum x^2 - (\sum x)^2 = 50\)

m = 105000/50 = 2100

For y-intercept b:

\(\rm b = \dfrac{\sum y -m \sum x}{n}\)

After calculating:

b = -4166040

The line becomes:

y = 2100x -4166040

If x = 2025 put this value in the line, we get:

y = 86460

Thus, the line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

Alex spend $1507.92 in total to buy this stock at 3% charges on each shares.

Shares represent equity ownership in a corporation or financial asset, owned by investors who exchange capital in return for these units.

Alex buys 30 shares of Walmart at the close price of $48.80.

His broker charges him 3% of each share.

Purchasing of 30 shares =48.80 *30

                                         =$1464

Now we have to find the 3% of total purchasing of shares.

So,

Broker's fees =\(\frac{3}{100}*1464\)

                      = 0.03 * 1464

                      = 43.92

So, total cost of stock= 1464+43.92

                                   = 1507.92

Hence, Alex spend $1507.92 in total to buy this stock.

The distance between the waterfall and the lake is 12.25 km.

The distance between the waterfall and the lake as "d".

We have a triangle with two sides given: 13.6 km (south) and an included angle of 228 degrees.

Using the law of cosines, the formula for finding the third side is:

d² = a² + b² - 2abcos(C)

Where:

a = 13.6 km

b = unknown (d)

C = 180 degrees - 228 degrees (to convert the bearing to an angle)

Now we can calculate:

C = 180° - 228° = -48° (since we need to use the interior angle)

d²= (13.6 km)² + (d)² - 2(13.6 km) (d)cos(-48°)

Simplifying and solving for "d":

d² = 184.96 km² + d²- 27.2 km.d.cos(-48°)

d = 184.96 km² / (27.2 km×cos(-48°))

cos(-48°) = 0.6691.

d = 184.96 km² / (27.2 km × 0.6691)

d = 12.245 km

2. If the company offered an extra large pizza, you could find out how much of it a person ate if they cut their own piece with a central angle of M°

Andy's oldest daughter ate the most pizza. She ate the entire personal pizza, which is 10 inches in diameter. This means that she ate 100% of the pizza. Andy's wife ate 2/6 of the small pizza, which is 12 inches in diameter. This means that she ate 1/3 of the pizza. Andy's younger daughter ate 1/8 of the medium pizza, which is 14 inches in diameter.

This means that she ate 12.5% of the pizza. Andy cut himself a piece that had a central angle of 180° from the large pizza, which is 16 inches in diameter. This means that he ate 50% of the pizza.

The least amount of pizza was eaten by Andy's younger daughter. She only ate 1/8 of the medium pizza.

2. If the company offered an extra large pizza, you could find out how much of it a person ate if they cut their own piece with a central angle of M° by using the following formula:

Percentage of pizza eaten = (M° / 360°) * 100%

For example, if a person cut themselves a piece of an extra large pizza with a central angle of 180°, they would have eaten 50% of the pizza.

Percentage of pizza eaten = (180° / 360°) * 100% = 50%

The proton number of the particle during beta decay is

The proton number of an atom is also referred to as its atomic number, and it indicates the number of protons in the nucleus of an atom.

In the equation for the beta decay of Lithium-8,

8Li --> 8Be + e- + νe

we see that the Lithium-8 nucleus (8Li) is transformed into a Beryllium-8 nucleus (8Be). Therefore, the Beryllium nucleus that is formed has the same proton number as the original Lithium nucleus, which is Z=3.

Thus, the Beryllium-8 nucleus that is formed as a result of the beta decay of Lithium-8 has a proton number of 4, since it has gained one proton in the process.

a) The initial height of the rock is of 48 feet.

b) It takes 1 seconds for the rock to reach maximum height.

c) The rock's maximum height is 50 feet.

d) It takes 6 seconds for the rock to land on the ground.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

\(f(x) = ax^{2} + bx + c\)

It's vertex is the point \((x_{v}, f(x_{v})\)

In which

\(x_{v} = -\frac{b}{2a}\)

If a<0, the vertex is a maximum point, that is, the maximum value happens at \(x_{v}\), and it's value is \(f(x_{v})\)

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

\(ax^{2} + bx + c, a\neq0\).

This polynomial has roots \(x_{1}, x_{2}\) such that \(ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})\), given by the following formulas:

\(x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}\)

\(x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}\)

\(\bigtriangleup = b^{2} - 4ac\)

In this question:

The height of the ball after t seconds, in feet, is given by:

\(h(t) = -2t^2 + 4t + 48\)

Which is a quadratic equation with \(a = -2, b = 4, c = 48\)

a) What is the initial height?

This is \(h(0) = 48\). So the initial height of the rock is of 48 feet.

b) How many seconds does it take to reach the maximum height?

This is the value of t at the vertex. So

\(t_{v} = -\frac{b}{2a} = -\frac{4}{2(-2)} = 1\)

It takes 1 seconds for the rock to reach maximum height.

c) What is the rock's maximum height?

This is the height of the ball after 1 second. So

\(h(1) = -2(1)^2 + 4(1) + 48 = 50\)

The rock's maximum height is 50 feet.

d) How many seconds does it take to for the rock to land on the ground?

This is t for which \(h(t) = 0\), so we solve the quadratic equation.

\(\bigtriangleup = (4)^2-4(-2)(48) = 400\)

\(t_{1} = \frac{-4 + \sqrt{400}}{2*(-2)} = -4\)

\(t_{2} = \frac{-4 - \sqrt{400}}{2*(-2)} = 6\)

Time is a positive measures, so it takes 6 seconds for the rock to land on the ground.

No, the expression (x^3 - 1) / (x^2 - 1) does not simplify to x.

To simplify the expression, let's first factorize both the numerator and denominator.

The numerator can be factorized using the difference of cubes formula: a^3 - b^3 = (a - b)(a^2 + ab + b^2). So, we have (x^3 - 1) = (x - 1)(x^2 + x + 1).

The denominator is a difference of squares: a^2 - b^2 = (a - b)(a + b). Therefore, (x^2 - 1) = (x - 1)(x + 1).

Now, we can simplify the expression by canceling out the common factors in the numerator and denominator:

[(x - 1)(x^2 + x + 1)] / [(x - 1)(x + 1)]

The (x - 1) terms cancel out, leaving us with:

x^2 + x + 1 / (x + 1)

So, the simplified form of the expression is (x^2 + x + 1) / (x + 1), which is not equal to x.
