The probability of the event occurring at odds of 11 to 28 is 11/39.
What is Odds and Probability?The odds of an event are other way of expressing the likelihood of an event occurring. Use the below formula for converting the probabilities and odds .
Probability = odds/(1+ odds)
We have, the odds for a certain event = 11 to 28 i.e, 11/28
The probability of the event occuring say, P =
= odds/(1+ odds) = (11/28)/( 1 + 11/28 )
=> P = (11/28 )/(( 28+ 11)/28)
=> P = (11/28 )/(39/28)
=> P =( 11/28)× 28/39
=> P = 11/39
Since 11 is prime number, this fraction cannot be reduced. Hence, required fraction is 11/39.

Adrian and his children went into a grocery store and will buy apples and
mangos. Each apple costs $2.25 and each mango costs $2. Adrian has a total
of $25 to spend on apples and mangos. Write an inequality that would
represent the possible values for the number of apples purchased, a, and the
number of mangos purchased, m.
We can represent the number of apples purchased by Adrian as the variable "a" and the number of mangos purchased by Adrian as the variable "m". The total cost of apples can be represented as $2.25 * a, and the total cost of mangos can be represented as $2 * m. The inequality that represents the possible values for the number of apples and mangos that Adrian can purchase is $2.25 * a + 2 * m <= 25.
A truck hauls a car cross-country. The truck's mass is 5.00x10 kg and the car's mass is 1.60x10 kg. If the force of propulsion resulting from the truck's turning wheels is 2.50x10' N, then determine the acceleration of the car (or the truck) and the force at which the truck pulls upon the car. Assume negligible air resistance forces. 3. Find the net forces for Situation 1 & 2 in page 56 of the module. 4. Figure below shows a truck is hauling a trailer along a level road. Find the force D that moves the truck forward. Use the given free body diagram. *27000 8500 0.7 m/? Drawbar D Trailer Truck
The truck is propelled forward by force D of 2.769 * 10⁴ N and acceleration of 0.78 m/s2.
What is Force?The definition of force is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
Given, Mass of the truck = 5000 kg
Mass of car = 1600 kg
Force applied = 25000 N
As we know Force (F) =m.a
Where m = mass of the body
a = acceleration of the body
25000 = (5000 + 1600) * a
a = 25000/ 6600 = 3.7878.
a = 3.79 m/s²
According to diagram D = ma
m = 27000 + 8500 = 35500 kg
a = 0.78 m/s²
so D = 35500 * 0.78 = 27690N
Therefore, Force D that moves the truck forward is 2.769 * 10⁴ N, and acceleration is 0.78 m/s².

What do we mean by equidistant?
A point is said to be equidistant from a set of objects if the distances between that point and each object in the set are equal.
In two-dimensional Euclidean geometry, the locus of points equidistant from two given (different) points is their perpendicular bisector. In three dimensions, the locus of points equidistant from two given points is a plane, and generalising further, in n-dimensional space the locus of points equidistant from two points in n-space is an (n−1)-space.
For a triangle the circumcentre is a point equidistant from each of the three vertices. Every non-degenerate triangle has such a point. This result can be generalised to cyclic polygons: the circumcentre is equidistant from each of the vertices. Likewise, the incentre of a triangle or any other tangential polygon is equidistant from the points of tangency of the polygon's sides with the circle.

What is the slope of a line Y − 3x − 5?
Three is the slope of the line y= 3x + 5.
The slope of a line is a measure of its steepness or incline. It is defined as the change in the y-value of a point on the line divided by the corresponding change in the x-value.
In the equation y = 3x + 5, the coefficient of x (3) is the slope of the line. Therefore, the slope of the line y = 3x + 5 is 3.
A line's slope might be zero, positive, negative, or undefinable. Positive slope lines climb as they move from left to right. A negative slope line slopes downward as it moves from left to right. Zero slopes indicate that a line is horizontal. An arbitrary sloped line has a vertical component.

Answer:
In a triangle, there are a total of 180 degrees.
Step-by-step explanation:
his is because the interior angles of a triangle always add up to 180 degrees. This is a property of triangles that can be proven using geometry.
Consider a triangle with three angles, A, B, and C. The sum of the angles in a triangle is equal to the sum of the angles in a straight line, which is 180 degrees. Therefore, the sum of the angles in the triangle is A + B + C = 180 degrees. This means that the three angles in a triangle always add up to 180 degrees.
It is important to note that this applies to all triangles, regardless of their size or shape. Whether the triangle is a right triangle, an isosceles triangle, an equilateral triangle, or any other type of triangle, the sum of its interior angles will always be 180 degrees.

Two friends argue over who brushes their teeth more often. To settle the
argument, they keep track of the number of mornings and nights they brush
and calculate a probability. These are shown in the table.
Probability of brushing

Braxton
0.72
0.85
Arabella
0.82
0.79
Who is more likely to brush both morning and evening? Assume all events are
independent.
Answer:
Arabella
Step-by-step explanation:
I am assuming the information in your table looks like this:
P(brushing in morning) P(brushing in evening)
Braxton .72 .85
Arabella .82 .79
Now, to find the probability either of Braxton or Arabella brushes in both the morning and evening (knowing they are independent), we multiply them together.
P(Braxton brushes in morning AND evening) = .72 × .85 = .612 = 61.2%
P(Arabella brushes in morning AND evening) = .82 × .79 = .6478 = 64.78%
Since 664.77% > 61.2%, we know that Arabella is more likely to brush her teeth in both the morning and evening compared to Braxton
Arabella is more likely to brush both morning and evening than Braxton, as her probability of brushing both morning and evening is higher.
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
To find out who is more likely to brush both morning and evening, we need to calculate the probability of each person brushing both morning and evening and compare the results.
For Braxton, the probability of brushing both morning and evening is:
P(Braxton brushes both morning and evening) = P(Braxton brushes in the morning) × P(Braxton brushes in the evening)
= 0.72 × 0.85
P ( B ) = 0.612
For Arabella, the probability of brushing both morning and evening is:
P(Arabella brushes both morning and evening) = P(Arabella brushes in the morning) × P(Arabella brushes in the evening)
= 0.82 × 0.79
P ( A ) = 0.6478
And , P ( A ) > P ( B )
Therefore, Arabella is more likely to brush both morning and evening than Braxton, as her probability of brushing both morning and evening is higher.
Hence , the probability is solved

The correct option is C. It is safe to apply the central limit theorem, even if the sample size for each sample is 15, if the sample population is normally distributed.
The central limit theorem states that, if you take repeated samples of a population and calculate the mean of each sample, the distribution of the means of those samples will tend to be normally distributed, provided that the sample size is large enough. This means that, even if the original population is not normally distributed, the distribution of the means of the samples will tend towards a normal distribution as the sample size increases.
However, if the original population is already normally distributed, then you can apply the central limit theorem with a smaller sample size and still expect the distribution of the means of the samples to be normally distributed. Therefore, in order for it to be safe to apply the central limit theorem with a sample size of 15, the sample population must be normally distributed.

Part A
How long is each side of the sandbox? Enter your answer in the box.
feet ( Input Answer )
Part B
The total cost of sand to fill the sandbox is $59.48. Lauren and 3 friends divide the cost equally.
How much does each person pay? Enter your answer in the box.
$ ( Amount??? )
Answer:
To solve this problem, we need to first find the length of each side of the sandbox. Since the sandbox is an octagon with 8 equal sides, we know that the perimeter of the sandbox is 8 times the length of each side. Thus, we can use the formula for perimeter to find the length of each side:
Perimeter = 8 * Side Length
Substituting the given values into this formula, we get:
18.8 feet = 8 * Side Length
Dividing both sides of the equation by 8, we get:
Side Length = 2.35 feet
Therefore, each side of the sandbox has a length of 2.35 feet.
________________________________________________________
To find the amount of money that each person pays to fill the sandbox, we need to divide the total cost by the number of people involved. In this case, there are 4 people in total, so each person pays 1/4 of the total cost. Thus, the cost per person is $59.48 / 4 = $14.87.
