Probability and Stats: Suppose a group of research proposals was evaluated by a panel of experts to decide whether or not they were worthy of funding. When these same proposals were submitted to a second independent panel of experts, the decision to fund was reverse in 74 % of the cases. If the probability that a proposal is judged worth of funding by the first panel is 22 %, what is the probability that a worthy proposal is disapproved by both panels?
Answer: Let's define the events:
A: a proposal is judged worthy of funding by the first panel
B: the decision to fund a proposal is reversed by the second panel
We want to find the probability of the intersection of events A and B (i.e., a worthy proposal is disapproved by both panels). We can use the formula:
P(A and B) = P(B|A) * P(A)
We know that P(A) = 0.22 (the probability that a proposal is judged worthy of funding by the first panel). We also know that when a proposal is judged worthy of funding by the first panel, the probability that the decision to fund is reversed by the second panel is 0.74 (i.e., P(B|A) = 0.74).
Plugging in these values, we get:
P(A and B) = 0.74 * 0.22 = 0.1628
Therefore, the probability that a worthy proposal is disapproved by both panels is 0.1628, or approximately 16.28%.

y = √24²+32² = √1600 = 40
find base angle Ф on the right:
Ф = sin⁻¹(32/40) = 53.13
find other base angle (sum of interior angles of a Δ is 180):
180 - 90 - 53.13 = 36.87
now you can use the Law of Sines to find z, x:
40/sin36.87 = z/sin53.13 = (x+24)/sin90
z = 40(sin53.13)/sin36.87 = 53.33
sin36.87(x+24) = 40(sin90)
x+24 = 40/sin36.87 = 66.66
x = 66.67 - 24 = 42.67
double check the answers:
y² + z² = (x+24)²
40² + 53.33² = (42.67 + 24)²
1600 + 2892 = 4444

the sides of a rectangle are -x + 18 and x + 4.what is the area?
Answer:
The area of a rectangle is given by the product of its length and width. In this case, the length of the rectangle is -x + 18, and the width is x + 4. So, the area is:
Area = (length) x (width)
= (-x + 18) x (x + 4)
= -x^2 + 14x + 72
Therefore, the area of the rectangle is -x^2 + 14x + 72.
Explain how to identify the major and minor axes of an ellipse are by looking at both the graph and the equation.
In the graph, the major axis is the horizontal axis, while the minor axis is the vertical axis.
What is ellipse?An ellipse is a geometric shape that is a type of curve. In mathematics, an ellipse is defined as a set of points in a plane, such that the sum of the distances between any point on the curve and two fixed points is a constant which is known as foci.
To identify the major and minor axes of an ellipse, you can use both the graph and the equation of the ellipse.
Identify the major and minor axes using the graph: The major axis is the longest diameter of the ellipse, which passes through the center and touches the curve at two points called the vertices. The minor axis is the shortest diameter of the ellipse, which also passes through the center and touches the curve at two points called the co-vertices. On the graph, the major axis is the horizontal axis, while the minor axis is the vertical axis.
Identify the major and minor axes using the equation: The equation of an ellipse can be written in the standard form:
[tex]\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} = 1[/tex]
where the ellipse's center is (h, k), the semi-major axis' length is a, and the semi-minor axis' length is b. The semi-major axis is half the length of the major axis, while the semi-minor axis is half the length of the minor axis. Therefore, you can identify the major and minor axes by looking at the denominators of the terms that contain x and y in the equation. The larger denominator corresponds to the semi-major axis, while the smaller denominator corresponds to the semi-minor axis.

Suppose you are a (junk) bond broker who buys only bonds that have a 50% chance of default. You want a portfolio with at least five bonds that do not default. You can dispose of the other bonds in the portfolio with no great loss. What is the smallest number of bonds you should buy if you want to be at least 97% sure that five or more bonds will not default?
Answer:
We should buy at least 19 bonds to have at least a 97% chance of getting 5 or more bonds that do not default.
Step-by-step explanation:
This problem can be solved using the binomial distribution, which can tell us the probability of getting a certain number of successes in a given number of trials, each with a certain probability of success. In this case, the trials are the bonds, the probability of success is 50% (the chance that a bond will not default), and we want to know how many bonds we need to buy to have at least a 97% chance of getting 5 or more successes.
Let X be the number of bonds that do not default. We want to find the smallest value of n (the total number of bonds we buy) such that P(X ≥ 5) ≥ 0.97.
Using the binomial distribution, we can calculate that the probability of getting exactly k successes out of n trials with a probability p of success is:
P(X = k) = (n choose k) * p^k * (1 - p)^(n-k)
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items out of n without regard to order.
To find P(X ≥ 5), we can calculate the probabilities of getting 5, 6, 7, 8, 9, or 10 successes and add them up:
P(X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
We want this probability to be at least 0.97, so we can set up the following inequality:
P(X ≥ 5) ≥ 0.97
P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) ≥ 0.97
We can then use a spreadsheet or a binomial probability table to find the smallest value of n that satisfies this inequality. For example, using Excel's BINOM.DIST function, we can enter the following formula in a cell:
=BINOM.DIST(4,n,0.5,TRUE) + BINOM.DIST(5,n,0.5,TRUE) + BINOM.DIST(6,n,0.5,TRUE) + BINOM.DIST(7,n,0.5,TRUE) + BINOM.DIST(8,n,0.5,TRUE) + BINOM.DIST(9,n,0.5,TRUE) + BINOM.DIST(10,n,0.5,TRUE)
where n is the number of bonds we want to buy, and TRUE indicates that we want to calculate the cumulative distribution function (CDF) up to the given value of k.
We can then use Excel's Goal Seek tool to find the smallest value of n that makes this formula equal to 0.97. For example, if we set the target value to 0.97 and the "Set cell" to the formula cell, and we vary the "To value" of n, Goal Seek finds that the smallest value of n that satisfies the inequality is 19. Therefore, we should buy at least 19 bonds to have at least a 97% chance of getting 5 or more bonds that do not default.

This means that the quiz scores can be described as a bell-shaped curve, with the mean score of 78 points being the highest peak. The 68% of the data that lies within 1 standard deviation of the mean would be between 72 and 90 points, which is the range specified in the question, so the answer is 81.5%. This is because 68% of the data lies within 1 standard deviation of the mean and 13.5% of the data lies within the second standard deviation of the mean. The sum of these two figures (68% + 13.5%) is 81.5%. Therefore, the percentage of students with quiz scores between 72 and 90 points would be 81.5%.

You work for a pet-grooming service. You record the number of animals you groomed each day over a 10-day period: 7, 10, 8, 9, 7, 11, 8, 6, 7, and 9. You state that the typical number of animals that you can groom is the mean of 8.2 animals per day.
Does this measure of central tendency describe the data well?
Yes, because the mean always describes data well.
Yes, because there are no outliers to skew the data.
No, because it is not possible to groom 0.2 of an animal.
No, because the most common number of dogs groomed is 7.
Yes, because half of the time, it is possible to groom more than 8.2 and half the time less than 8.2.
No because it is not possible to groom 0.2 of an animal.
What is median ?
The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, the median is helpful. The median is one of the simple to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the center of a sequence to determine its value.
To support this, we can also calculate the median and mode of the data set to see if they are close to the mean. The median is the middle value of the sorted data set, which is 8 in this case, and the mode is the most common value, which is also 7 and 8 in this data set. So, the mean, median, and mode are all relatively close to each other, indicating that the data is roughly symmetric around the center.
Based on the given data, the mean of 8.2 animals per day can be considered as a reasonable measure of central tendency.
Hence the answer is No because it is not possible to groom 0.2 of an animal.

The scale drawing has a scale of 1 inch:9yards. What is the total area of the composite figure.
The figure is a right triangle with a height of 6 in and the height of 6 inches. The rectangle has a length of 7 inches and a width of 6 inches.
How do you solve?
The total area of the composite figure is 107/216 square yards.
What is Area?
Area is a measure of the size of a two-dimensional shape or surface. It is the amount of space inside the boundaries of a flat object, measured in square units such as square meters, square feet, or square inches.
To find the total area of the composite figure, we need to first convert the dimensions from inches to yards, since the given scale is in inches per yards.
Since 1 yard is equal to 3 feet, which is equal to 36 inches, we have:
The height of the triangle is 6/36 = 1/6 yards.
The base of the triangle is 9 times the height, which is 9/6 = 3/2 yards.
The length of the rectangle is 7/9 yards.
The width of the rectangle is 6/9 = 2/3 yards.
The area of the triangle is:
(1/2) x (1/6) x (3/2) = 1/8 square yards.
The area of the rectangle is:
(7/9) x (2/3) = 14/27 square yards.
Therefore, the total area of the composite figure is:
1/8 + 14/27 = 107/216 square yards.

Find all the missing angles in the diagram below. Explain how you used two different angle theories to find at least two missing angles.
The measures of the angles in the parallel lines is
m∠a = 97°
m∠b = 15°
m∠c = 68°
m∠d = 68°
What are Parallel Lines Cut by Transversal?Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
Let the two parallel lines be represented as l and m
Now , the transversal line is t
The measure of m∠a = 97° ( corresponding angles )
The measure of m∠d = 180° - 112° ( angles in a straight line = 180° )
So , the measure of m∠d = 68°
The measure of m∠c = measure of m∠d ( alternate interior angles )
So , the measure of m∠c = 68°
From the triangle formed by the intersection of lines ,
The measure of m∠b = 180° - ( a + d ) ( angles of a triangle = 180° )
So , the measure of m∠b = 180° - ( 97° + 68° )
The measure of m∠b = 15°
Hence , the measures of angles are solved

Use all the numbers below and use addition, subtraction, multiplication and/or division, and find an expression that
equals the target number. The target number is -2. The numbers provided are -1, -3, -5, -7, and -2
Answer: One possible expression that equals the target number (-2) using the given numbers (-1, -3, -5, -7, and -2) and basic arithmetic operations (+, -, *, /) is:
-3 * (-5) + (-7) - (-2) / (-1) = -2
Explanation:
-3 * (-5) = 15 (multiplication of -3 and -5 gives +15)
-7 - (-2) = -5 (subtracting a negative is the same as adding a positive, so -7 - (-2) = -7 + 2 = -5)
-2 / (-1) = 2 (dividing a negative number by a negative number gives a positive result, so -2 / (-1) = 2)
Therefore, 15 + (-5) + 2 = -2
