The probability of the marksman hitting the long-range target in 5 shots is 0.1429.

The geometric distribution is a Bernoulli experiment that predicts the likelihood of the first success after a certain number of failures. Negative-binomial and binomial distributions are two different forms of Bernoulli trials.

P = 0.268

x = 5

Use the geometric probability mass function below to calculate the probability:

P(X = x) = [tex](1 - P)^{(x-1)}[/tex]× P

P(X = x) = [tex](1 - 0.268)^{(3-1)}[/tex]× 0.268

P(X = x) = 0.1429

The probability that it takes 5 shots for the marksman to hit the long-range target is 0.1429.

A person must score at least 129.24 to be in the top 10%.

Using the z-table, find the z-score that corresponds to the 90% probability.

probability = 0.90

z-score = 1.2825

For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.

The z-score can be calculated using the formula below.

z-score = (x – μ) / σ

where x = individual data value

μ = mean

σ = standard deviation

Plug in the values and find the score to be in the top 10%, x.

z-score = (x – μ) / σ

1.2825 = (x – 110) / 15

x – 110 = 19.2377

x = 129.24

The Interquartile range i.e 1.5 (IQR) is used to identify outliers in a set of data which is the correct answer would be option (A).

We may build up a "fence" outside of Q1 and Q3 by using the Interquartile range (IQR) method of spotting outliers. Outliers are values that fall outside of this range.

To construct this barrier, we take 1.5 times the IQR, deduct it from Q1, and add it to Q3. This provides us with the lowest and maximum fence posts against which we will compare each observation.

Outliers are observations that are greater than 1.5 IQR below or above Q1. Minitab's default strategy for identifying outliers is this.

Therefore, the Interquartile range (IQR) is used to identify outliers in a set of data.

Answer:

x = 42

see below for the angle measures.

Step-by-step explanation:

The angle marked 2x - 9 is sort of outside the triangle. It is called an exterior angle. The other two angles are called remote interior angles. "Remote" means that they are away from the exterior angle. When you have this set up, the two remote angles added together EQUAL the exterior one.

x+5 + 28 = 2x - 9

x + 33 = 2x - 9

Subtract x.

33 = x - 9

Add 9.

42 = x

So x = 42° which if you put that back into the expressions you can find the measures of the one remote interior angle (the other we know is 28°) and the exterior angle.

remote int angle:

x+5

= 42 + 5

= 47°

Exterior angle:

2x - 9

= 2(42) - 9

= 84 - 9

= 75°

(You can also then find the completely unmarked angle which is 180°- 75° which is 105°)

Step-by-step explanation:

The slope of the line = rise of the line / run of the line = 2/2 = 1.

The slope (m) of a line can be determined by finding the ratio of the rise of the line to the run of the line, which is, the change in y over the change in x.

Referring to the image attached below, the blue line in the given graph shows the rise of the line while the red line shows the run of the line.

Therefore:

Rise of the line = 2 units

Run of the line = 2 units

Slope of the line (m) = rise/run = 2 units/2 units

Answer:

35000

Step-by-step explanation:

So the number is 34582

now look at the hundreds

if it is 5 or over then we add a thousand to and subtract what ever the lower than thosand

and in this case it is 5 so we round UP

and now we have 35000

The answer is 35,000.

To round to the nearest thousand, we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.

Since in this case the last three digit consists of 582 which is greater than 500 so we round the thousands digit up i.e. from 4 to 5 in this case.

The point-slope equation of this line is y - 7 = -7(x + 5).

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

Next, we would determine the slope of this line by using this formula:

Slope, m = Δy/Δx

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Substituting the given parameters into the formula, we have;

Slope, m = (0 - 7)/(-4 + 5)

Slope, m = -7/1

Slope, m = -7

At point (-5, 7), the point-slope equation of the line is given by:

y - y₁ = m(x - x₁)

y - 7 = -7(x - (-5))

The value of x for the given triangle is 30°.

According to the question,

We have the following information:

We have a triangle.

Three angles of the triangle are x°, 65° and (x+55)°.

We know that the sum of all the three angles of a triangle is 180°.

So, the sum of these angles will be 180°.

Now, adding three angles:

x° + 65° + (x+55)° = 180°

(2x+120)° = 180°

2x = 180-120

2x = 60

x = 60/2 (2 was in the multiplication on the left hand side. So, it is in the division on the left hand side.)

x = 30°

Hence, the value of x in the angles of the given triangle is 30°.

The probability that the experiment results in 9 or more successes = 0.0676

A binomial distribution is given by,

P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ  ,

where p is the probability of success and x is the random variable for success in n trials.

A binomial experiment has only two outcomes- success or failure.

Here, the number of trials, n = 10

Probability of success = 0.63

The probability for 9 or more success = P( X = 9, 10)

                                                               = P (X = 9) + P(X = 10)

So P( X = 9) =  ¹⁰C₉ (0.63)⁹ (1-0.63)¹⁰⁻⁹

                   = 10 x 0.0156 x 0.37

                   = 0.05772

and P(X = 10) = ¹⁰C₁₀ (0.63)¹⁰(1-0.63)¹⁰⁻¹⁰

                     = 1 x 0.009849 x 1

                     =  0.009849

Hence probability for 9 or more success = 0.05772 + 0.009849

                                                                    = 0.067569

So, the volume is 486 ft^3.

Total 150 miles Jan drove than Ian.

Set the time Ian traveled as I, and set Han's speed as H.

Therefore, Jan's speed is H+5.

We get the following equation for how much Han is ahead of Ian;

H + 5I = 70.

The expression for how much Jan is ahead of Ian is; 2 (H + 5) + 10I

This simplifies to: 2H + 10 + 10I

However, this is just 2(H + 5I) + 10

We know that:

Apply it to the given to get:

The solutions to the quadratic equation using completing the square method are  x = -(√109)/2 - 5/2 and x = (√109)/2 -5/2.

Given the quadratic equation in the question;

To solve using  completing the square method, first add 21 to both sides

x² + 5x - 21 = 0

x² + 5x - 21 + 21 = 0 + 21

x² + 5x = 21

Next, create a trinomial square on the left side of the equation, determine the value that is equal to the square of half of b which is 5.

( b/2 )² = ( 5/2 )²

Now, add ( 5/2 )²  to both sides of the equation

x² + 5x + ( 5/2 )² = 21 + ( 5/2 )²

Simplify

x² + 5x + 25/4 = 21 + 25/4

Add 21 and 25/4

x² + 5x + 25/4 = 109/4

Factor the perfect trinomial.

x² + 5x + 25/4 = 109/4

( x + 5/2 )² = 109/4

Solve for x by taking the square root of both sides.

x + 5/2 = ±√( 109/4 )

x = -5/2 ±√( 109/4 )

x = ±(√109)/2 -5/2

x = -(√109)/2 - 5/2, (√109)/2 -5/2

Therefore, the solutions to are x = -(√109)/2 - 5/2 and x = (√109)/2 -5/2.
