You randomly choose one of the tiles shown below. Find the favorable outcomes of the Event.

Each consecutive element of the series has one less blue points than the before element, with that, we conclude that the correct option is D, where there is only one blue point.

Here we can see a series of 3 elements.

the first element is a circle with 4 blue points on its circumference, such that the points are connected to form a rectangle.

The next element is a circle with 3 blue points on it, such that when the points are connected a triangle is formed.

The third element is a circle, this time with 2 points, and the connection forms a segment.

So what we can see is that in each consecutive element the number of blue points on the circumference of the circles decreases by one, so the logical conclusion is that the next element will have only one point on its perimeter, then the correct option is D, where we can see only one blue point on the perimeter of the circle.

Answer:

7+x

Step-by-step explanation:

X will be the unknown

Answer: Is in the screenshot

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

He saved 180 naira by buying three dozen eggs in sixes Instead of separately.

A group of twelve is referred to as a dozen and is frequently abbreviated as doz or dz. Given that there are roughly twelve lunar cycles (or months) in each cycle of the sun (or year), the number twelve may be one of the earliest primitive integer groupings.

Twelve is useful because it has the greatest number of divisors among numbers up to its double, a property shared only by the numbers 1, 2, 6, 12, 60, 360, and 2520.

1 dozen = 12

3 dozen = 36

6 eggs costs 150 naira

36 eggs costs 150 naira = 36/6 × 150

                                         = 900 naira

Each egg costs 30 naira, then 36 eggs costs = 36 × 30

                                                                            = 1080 naira

Savings = 1080 - 900 = 180 naira

Thus, He saved 180 naira by buying three dozen eggs in sixes Instead of separately.

Answer:

y = 3x + 1

Step-by-step explanation:

The formula for equation of a line in slope intercept form is;

y = mx + c

Where;

m is slope

c is y-intercept

Now, since we have coordinates, we will get the equation as;

(y - y1)/(x - x1) = m

(y - 1)/(x - 0) = 3

y - 1 = 3x

y = 3x + 1

Answer:

Step-by-step explanation:

The correct answer is, "a divided by 5"

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Brainliest pls UnU

The requried, percentage of students who study less than 2.50 hours a day is approximately 25.14 percent.

A Z-score is stated as the fractional model of data point to the mean using standard deviations.

We need to convert 2.50 hours to a standard score (z-score) using the formula,

z = (x - μ) / σ

where x is the value we want to convert, μ is the mean, and σ is the standard deviation.

z = (2.50 - 3.00) / 0.75

z = -0.67

This means that 2.50 hours is 0.67 standard deviations below the mean.

We can use a standard normal distribution table or a calculator to find the percentage of the distribution that falls below this standard score. For example, using a standard normal distribution table, we can look up the area to the left of z = -0.67 and get:

P(z < -0.67) = 0.2514

So the correct answer is (a) 25.14 percent.

Answer:

the polygon is a trapezoid

Step-by-step explanation:

(1, −1), (4, −1), the two points having the same y coordinate they make a horizontal line

(−1, −3), (7, −3) the two points having the same y coordinate they make another horizontal line

All horizontal lines are parallel.

The shape is a trapezoid because it has one pair of parallel lines.

The domain of \(b\,\circ \,a\,(x)\) is \([1, +\infty)\).

The composition of two functions consists in replacing the variable of the former function (\(b(x)\)) by the latter function (\(a(x)\)). If we know that \(b(x) = \sqrt{x-4}\) and \(a(x) = 3\cdot x +1\), then the composite function:

\(b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}\)

\(b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}\)   (1)

Since the composite function is a square root function, then the domain fulfill the following inequation:

\(3\cdot x -3 \ge 0\)

\(x \ge 1\)

Hence, the domain of \(b\,\circ \,a\,(x)\) is \([1, +\infty)\). \(\blacksquare\)

*Note, this is only for the sum of the interior angles. Exterior angles on polygons are ALWAYS equal to 360 degrees.

Answer:

triangle A because the measurements would be the same. If you add 30 + 112, you get 150. Triangles add to 180, so the missing angle of the first one is 30.

The volume of the bin is the amount of books it can contain.

455 books will fit in the bin

The dimension of the book is given as:

\(\mathbf{Book = 0.75ft, 0.75ft, 0.25ft}\)

The dimension of the bin is given as:

\(\mathbf{Bin = 4ft, 4ft, 4ft}\)

Start by calculating the volume of the book

\(\mathbf{Book = 0.75ft \times 0.75ft\times 0.25ft}\)

\(\mathbf{Book = 0.140625ft^3}\)

Next, calculate the volume of the bin

\(\mathbf{Bin = 4ft \times 4ft \times 4ft}\)

\(\mathbf{Bin = 64ft^3}\)

So, the number of books (n) is:

\(\mathbf{n = \frac{Bin}{Book}}\)

This gives

\(\mathbf{n = \frac{64ft^3}{0.140625ft^3}}\)

Cancel out the units

\(\mathbf{n = \frac{64}{0.140625}}\)

\(\mathbf{n = 455.11}\)

Remove the decimals

\(\mathbf{n = 455}\)

Hence, 455 books will fit in the bin

Using the binomial distribution, it is found that there is a 0.9499 = 94.99% probability that a student guesses at least 2 answers  correctly.

--------------------------

For each question, there are only two possible outcomes, either the student guesses the correct answer or not. The probability of guessing the correct answer on a question is independent of any other question, which means that the binomial distribution is used to solve this question.

Binomial probability distribution  

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)  

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

\(P(X \geq 2) = 1 - P(X < 2)\)

In which

\(P(X < 2) = P(X = 0) + P(X = 1)\)

Then

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{17,0}.(0.25)^{0}.(0.75)^{17} = 0.0075\)

\(P(X = 1) = C_{17,1}.(0.25)^{1}.(0.75)^{16} = 0.0426\)

\(P(X < 2) = P(X = 0) + P(X = 1) = 0.0075 + 0.0426 = 0.0501\)

\(P(X \geq 2) = 1 - P(X < 2) = 1 - 0.0501 = 0.9499\)

0.9499 = 94.99% probability that a student guesses at least 2 answers  correctly.
