As a result, the anticipated value in this circumstance is -$1,750, which probability suggests that if the architect decides to bid on the design of the new museum, she can expect to lose $1,750 on average.
What is probability?Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% since there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many disciplines, including statistics, economics, science, and engineering.
0.15 x $45,000 = $6,750.
Consider the following scenario in which the architect is not granted the contract:
The likelihood of not winning the bid is 0.85.
In this case, the payback is -$10,000 (a negative value since the architect would lose the $10,000 cost of creating blueprints and presenting a model).
In this case, the anticipated value is:
0.85 x (-$10,000) = -$8,500.
We sum the anticipated values of both situations to determine the overall expected value:
$6,750 + (-$8,500) = -$1,750.
As a result, the anticipated value in this circumstance is -$1,750, which suggests that if the architect decides to bid on the design of the new museum, she can expect to lose $1,750 on average.

FIND THE SIZE OF XYZ
The angle of XYZ is approximately 87.6 degrees.
To find the angle of XYZ, you need to use the Law of Cosines, which states that c² = a² + b² - 2ab cos(C), where c is the side opposite the angle C. Given the side lengths of the triangle XYZ, you can find the measure of angle XYZ as follows:
First, use the Pythagorean Theorem to find the length of side XY: XY² = 5² + 12² = 169, so XY = √169 = 13.
Next, use the Law of Cosines to find the measure of angle YXZ: 13² = 7² + 8² - 2(7)(8)cos(YXZ), which simplifies to 169 = 113 - 112cos(YXZ). Solving for cos(YXZ), you get cos(YXZ) = (113 - 169) / (278) = -0.125.
Finally, take the inverse cosine (cos⁻¹) of -0.125 to find the measure of angle YXZ in degrees: YXZ ≈ 102.4°.
Therefore, the measure of angle XYZ is 180° - 90° - 102.4° = 87.6°.

"The set of 24, 25, 26, and 28 has a mean of 30." b. "15 is the median of this data set: 12, 14, 15, 13, and 16."
The first statement about mean is false.
The second statement about median is false.
What is mean and median?
The "mean" is the "average" of any data set. Sum of all the data and dividing that by the number of data will give the mean.
The "median" is the "middle" value in the given list of data.
At the first statement the values are 24,25,26,28.
Now the smallest value is 24 and the greatest value is 28. so the average or mean must be in between 24 and 28. It cant exceeds the value 28.
Here given that mean is 30 which is obviously greater than 28. So it cant be the mean of the given data set.
At the second statement the data are 12,14,15,13,16.
The listed values are not in ascending order Without making the values in ascending order we cant find the median. Now if we arrange the values in ascending order the list will be 12,13,14,15,16.
As there are 5 terms so there are odd number of terms. For that the median must be the middle value which is 14.
But here median is 15.
So it cant be the median of the data.

Four part spinner is spun twice total number of possible outcomes. What is the probability of spinning pink on both spins? What is the probability of not spinning orange either spin?
Probability of spinning pink on both spins = 1/4 and Probability of not spinning orange on either spin = 9/16.
What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
If a four-part spinner is spun twice, there are 16 possible outcomes (4 options on the first spin, multiplied by 4 options on the second spin).
To find the probability of spinning pink on both spins, we need to first determine how many outcomes result in pink on both spins. If we label the four parts of the spinner A, B, C, and D, and assume that pink is on part A, then there are four possible outcomes where pink appears on both spins: AA, AB, AC, and AD. Each of these outcomes has a probability of 1/16, since there are 16 total possible outcomes. So the probability of spinning pink on both spins is:
Probability of spinning pink on both spins = (number of outcomes where pink appears on both spins) / (total number of possible outcomes)
Probability of spinning pink on both spins = 4/16
Probability of spinning pink on both spins = 1/4
To find the probability of not spinning orange either spin, we need to determine how many outcomes do not have orange. If we assume that orange is on part B, then there are three outcomes on the first spin that do not result in orange: AB, AC, and AD. On the second spin, there are again three outcomes that do not result in orange: BA, CA, and DA. So there are a total of 3 x 3 = 9 outcomes where orange does not appear on either spin.
Again, each of these outcomes has a probability of 1/16, so the probability of not spinning orange on either spin is:
Probability of not spinning orange on either spin = (number of outcomes where orange does not appear on either spin) / (total number of possible outcomes)
Probability of not spinning orange on either spin = 9/16

What is a line plot?In Mathematics and Statistics, a line plot refers a type of graph that is used to graphically represent a data set above a number line, while using crosses, dots, or any other mathematical symbol.
Based on the data and information provided in the line plot shown in the image attached above, we can calculate the total amount of sugar that was consumed by Kylie in the past nine (9) days as follows:
Total sugar consumed = (1/8 + 1/8 + 1/8) + 1/4 + (3/8 + 3/8 + 3/8) + (5/8 + 5/8)
Total sugar consumed = 3(1/8) + 1/4 + 3(3/8) + 2(5/8)
Total sugar consumed = 3/8 + 1/4 + 9/8 + 10/8

a trapezoid is shown with bases AD and BC. if slopCe of AD is 1/2, what is the slope of BC
The slope of BC is 1/2, since the slope of AD is 1/2. This is because the rise and run of the two bases are the same.
What is slope?The slope of a line is defined as the ratio of the vertical change (the rise) to the horizontal change (the run).
In the case of an isosceles trapezoid, the two bases (AD and BC) are parallel and of equal length. Therefore, the slope of the two bases is the same.
Given that the slope of AD is 1/2, the slope of BC is also 1/2.
This is because the rise and run of the two bases are the same. Therefore, the ratio of rise to run is the same and the slope of both bases is 1/2.
To understand this better, let us consider the rise and run of the two bases:
AD: Rise = y² − y1, Run = x² − x1
BC: Rise = y² − y1, Run = x² − x1
Therefore,
Slope of AD = (y² − y1)/(x² − x1)
Slope of BC = (y² − y1)/(x² − x1)
Since the rise and run of the two bases are the same, the slope of the two bases is also the same.
Therefore, the slope of BC is 1/2, since the slope of AD is 1/2.

The population will exceed 2627 when t is greater than approximately 6.05.
What is inequality?Inequality is a mathematical cοncept that expresses a relatiοnship between twο values οr expressiοns, indicating that οne is greater than, less than, οr nοt equal tο the οther. An inequality is usually represented using symbοls such as < (less than), > (greater than), ≤ (less than οr equal tο), ≥ (greater than οr equal tο), and ≠ (nοt equal tο).
To solve for the value of t when the population exceeds 2627, we can set up the inequality:
p(t) > 2627
Substituting the given equation for p(t), we get:
1000[tex]e^{0.21t}[/tex] > > 2627
Dividing both sides by 1000, we get:
[tex]e^{0.21t}[/tex] > 2.627
Taking the natural logarithm of both sides, we get:
0.21t > ln(2.627)
Solving for t, we get:
t > ln(2.627)/0.21 ≈ 6.05
Therefore, the population will exceed 2627 when t is greater than approximately 6.05.

Integers a and b are such that

Find the possible values of a and the corresponding values of b.
(Answers are a= -3 , 2 and b= -18 , 12. But I don't know how to show the working so please help, thx)
The possible values of a and the corresponding values of b are; a= -3, 2 and b= -18, 12.
How to calculate possible and the corresponding values?Expanding the left-hand side of the equation:
(a + 3√5)² + a - b√5 = a² + 6a√5 + 45 + a - b√5
Combining like terms:
2a² + (2a - b)√5 + 45 = 51
Simplifying further:
2a² + (2a - b)√5 = 6
Now, since √5 is irrational, the only way the left-hand side can equal 6 is if both the rational and irrational parts are equal to 0. Therefore two equations:
2a² + 2a - b = 0 (Equation 1)
2a - b = 0 (Equation 2)
Solving Equation 2 for b:
b = 2a
Substituting this into Equation 1:
2a² + 2a - 2a = 0
Simplifying:
2a² = 0
Thus, a = 0 is a solution. However, a = 0 does not satisfy the original equation, since the left-hand side would be 45, which is not equal to 51. Therefore, we can divide both sides of Equation 1 by 2a to get:
a + 1 - b/2a = 0
Multiplying both sides by 2a:
2a² + 2a - b = 0
Substituting b = 2a:
2a² + 2a - 2a = 0
Simplifying:
2a² = 0
Thus, a = 0 is a solution. However, as noted above, a = 0 does not satisfy the original equation. Therefore, we must consider the case where a ≠ 0. Dividing both sides of Equation 2 by 2:
a - b/2 = 0
Solving for b:
b = 2a
Substituting into the original equation:
(a + 3√5)² + a - 2a√5 = 51
Expanding:
a² + 6a√5 + 45 + a - 2a√5 = 51
Combining like terms:
a² + 7a√5 - 6 = 0
Using the quadratic formula:
a = (-7√5 ± √(7²√5² - 4(1)(-6))) / 2(1)
Simplifying:
a = (-7√5 ± 13) / 2
Therefore, the possible values of a are -3 and 2. For each value of a, we can use b = 2a to find the corresponding value of b. Thus, the possible values of b are -18 and 12.
