Answer:
\(\frac{1}{8}\)
Step-by-step explanation:
Since there are four answer choices for question one, the chance of picking the correct answer is \(\frac{1}{4}\). However, there is also another question. That question is a true-or-false question, meaning that there is only two options. Therefore, the probability of picking the correct answer is \(\frac{1}{2}\). To find the probability of picking both correctly, you multiply the two together. \(\frac{1}{4} * \frac{1}{2} = \frac{1}{8}\), so the answer is \(\frac{1}{8}\).

The probability that either event will occur is 0.61
What is the probability that either event will occur?From the question, we have the following parameters that can be used in our computation:
Event A = 12
Event B = 10
Other Events = 14
Using the above as a guide, we have the following:
Total = A + B + C
So, we have
Total = 12 + 10 + 14
Evaluate
Total = 36
So, we have
P(A) = 12/36
P(B) = 10/36
For either events, we have
P(A or B) = 22/36 = 0.61
Hence, the probability that either event will occur is 0.61

Answers
He is 2√19 miles far way from starting point.
Suppose Billy starts at point A, turns at point B, and ends at point D, as shown below.
If Billy turns 60◦ northward and walks six miles, then we can draw a 30 − 60 − 90 triangle whose hypotenuse is 6 miles
It follows that Billy traveled 6/2 = 3 miles eastward during these 6 miles, and that he traveled 3√3 miles northward during these 6 miles. In total, Billy traveled 4 + 3 = 7 miles eastward and 3√ 3 miles northward.
By the Pythagorean Theorem, the distance from his starting point is q:

The relation does not relate y as a function of x because point (2,2) and (3,2) have the same y value. Hence, option 2 is the correct answer.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
We know that a function is a relationship between inputs where each input is related to exactly one output.
In the given graph (2,2) and (3,2) have the same y value that is two inputs have same output.

Fixed Points and Cobwebs (Calculator experiments) Use a pocket calculator to explore the following maps. Start with some number and then keep pressing the appropriate function key; what happens? Then try a different number-s the eventual pattern the same? If possi- ble, explain your results mathematically, using a cobweb or some other argument
Answers
When exploring maps using a pocket calculator, it's important to understand the concept of fixed points and cobwebs. Fixed points are values that do not change when the map is applied repeatedly. Cobweb diagrams help visualize the behavior of maps and can provide insights into the eventual pattern.
To explore a map using a pocket calculator, follow these steps:
Start with an initial number.
Apply the map by pressing the appropriate function key.
Repeat step 2 to see how the number changes with each iteration.
Observe the pattern that emerges over multiple iterations.
Repeat the above steps with a different initial number to compare the eventual patterns.
Mathematically, fixed points occur when applying the map does not change the value. In other words, if the map is f(x), a fixed point satisfies f(x) = x. By repeatedly applying the map starting from a fixed point, the value remains the same.
Cobweb diagrams are graphical representations of the iterative process, where each point on the diagram represents a value obtained from applying the map repeatedly. The diagram shows the connection between each iteration and helps visualize the behavior of the map.
By analyzing the cobweb diagrams and studying the properties of the map, one can determine whether the map has fixed points, cycles, or other interesting patterns. This analysis can be supported by mathematical reasoning and calculations.
It's important to note that the specific maps being explored are not mentioned in the question. To provide more specific insights, it would be helpful to know the particular maps and initial values being used.

a bearing of 150° By making a scale diagram find: -
a) The final distance of the port from the ship.
b) The final bearing of the port from the ship.
Answers
The final distance of the port from the ship is 75.63 km and the final bearing of the port from the ship is 263.57° using cosine and sine rules.
How to evaluate for the final distance and bearingConsidering the triangle formed by the ship ∆ABC where A, B and C are the points for; the port, where the ship changes its course, and its final bearing. The final distance "a" of the port from the ship is calculated with cosine rule as follows;
a² = b² + c² - 2(b)(c)cosA
a² = 40² + 70² - 2(40)(70)cos82°
a² = 1600 + 4900 - 5600cos82°
a² = 5720.63 {take square root of both sides}
a = 75.63
For the triangle ABC, by sine rule;
a/sinA = b/sinB = c/sinC
75.63/sin82° = 70/sinC
C = sin⁻¹(70 × sin82°/75.63) {by cross multiplication}
C = 66.43
angle C = 60 + 6.43 {60° is an alternate angle with angle 30° at the point B where the ship chenged course and 6.43° is a complementary angle at the 3rd quadrant of point C}
The final bearing of the port from the ship is calculated as;
180° + (90 - 6.43)° = 263.57°
Therefore, the final distance of the port from the ship is 75.63 km and the final bearing of the port from the ship is 263.57° using cosine and sine rules.

A skewed distribution is one in which the data is not uniformly distributed but rather concentrated on one side. In simple words, a skewed distribution is one in which one tail has a greater number of observations than the other tail, with the majority of data falling in the tail with the greater number of observations.
In a symmetric distribution, the data is uniformly distributed on both sides of the median, with half of the data lying to the right and half to the left.

Answers
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.
To calculate the actual distance between Beitbridge and Musina, given the scale of the map and the measured distance on the map, we can use the concept of scale.
The scale of the map is given as 1:3,000,000, which means that 1 cm on the map represents 3,000,000 cm in real life.
The measured distance on the map between Beitbridge and Musina is 1.3 cm.
To find the actual distance, we can set up a proportion using the scale:
1 cm on the map / 3,000,000 cm in real life = 1.3 cm on the map / x km in real life.
Simplifying the proportion, we have:
1 / 3,000,000 = 1.3 / x.
Cross-multiplying, we get:
x = (1.3 * 3,000,000) / 1.
x = 3,900,000 / 1.
x = 3,900,000 km.
The actual distance between Beitbridge and Musina is 3,900,000 kilometers.

Determine whether it is possible to find values of L > 0 so that the given boundary-value problem has precisely one nontrivial solution, more than one solution, no solution, and the trivial solution.
Answers
To determine the solutions to the given boundary-value problem, we must first analyze the values of L. If L is greater than 0, then we can use Sturm-Liouville theory to solve the problem.
If L is chosen in such a way that the boundary-value problem has a unique solution, then we have precisely one nontrivial solution. However, if L is chosen so that there are multiple solutions, we have more than one solution.
If L is chosen in such a way that the boundary-value problem has no solution, then there are no solutions, including the trivial solution. The trivial solution is the solution where all the unknowns are set to zero.
Therefore, it is possible to find values of L > 0 so that the given boundary-value problem has precisely one nontrivial solution, more than one solution, no solution, and the trivial solution depending on how L is chosen.
Involving values of L > 0, boundary-value problems, and nontrivial solutions. To determine whether it is possible to find values of L > 0 so that the given boundary-value problem has precisely one nontrivial solution, more than one solution, no solution, and the trivial solution, follow these steps:
1. Identify the boundary-value problem in question. This typically involves a differential equation and boundary conditions.
2. Analyze the boundary conditions and the differential equation to see if there is a possibility of finding values of L > 0 that satisfy the problem.
3. Determine if there is a trivial solution, which typically corresponds to a zero solution, where all the components of the solution are zero.
4. Check for the existence of nontrivial solutions. This may involve solving the differential equation for particular values of L > 0 and applying the boundary conditions.
5. Compare the results from steps 3 and 4 to determine if there is precisely one nontrivial solution, more than one solution, no solution, or only the trivial solution.

a caramel corn company gives four different prizes, one in each box. they are placed in the boxes at random. find the average number of boxes a person needs to buy to get all four prizes.
Answers
This problem can be solved using the concept of the expected value of a random variable. Let X be the random variable representing the number of boxes a person needs to buy to get all four prizes.
To calculate the expected value E(X), we can use the formula:
E(X) = 1/p
where p is the probability of getting a new prize in a single box. In the first box, the person has a 4/4 chance of getting a new prize. In the second box, the person has a 3/4 chance of getting a new prize (since there are only 3 prizes left out of 4). Similarly, in the third box, the person has a 2/4 chance of getting a new prize, and in the fourth box, the person has a 1/4 chance of getting a new prize. Therefore, we have:
p = 4/4 * 3/4 * 2/4 * 1/4 = 3/32
Substituting this into the formula, we get:
E(X) = 1/p = 32/3
Therefore, the average number of boxes a person needs to buy to get all four prizes is 32/3, or approximately 10.67 boxes.

Answers
Answer:
(0,16)
Step-by-step explanation:
Hi there!
The y intercept is the value in which the parabola passes through the y axis
Therefore, the value of x at the y intercept is 0
So to find the value of the y intercept, substitute x as 0 in the equation.
y=(2x-3)^2 + 7
If x=0, then:
y=(2(0)-3)^2 + 7
Multiply
y=(0-3)^2 + 7
Subtract 3 from 0
y=(-3)^2 + 7
Raise -3 to the second power
y= 9 + 7
Add 9 and 7 together
y = 16
So the y intercept is the point (0,16)
