Answer:
55%
Step-by-step explanation:
the question is asking what is the probability he has 8 hours of sleep GIVEN he has had 0 cups.
we find the number where 0 cups and 8 hours meets. that is 12.
divide that by P(0 cups). P(0 cups) is total of 0 cups, ie 22.
so answer is (12/72) / (22/72)
= 12/22
= 6/11
= 0.5454
= 55% to nearest whole percent

Point P is the interior of ∠OZQ. If m∠OZQ = 125 and m∠OZP = 62, what is m∠PZQ?
Answers
Answer:
\(PZQ = 63\)
Step-by-step explanation:
Given
\(OZQ = 125\)
\(OZP = 62\)
Required
Determine PZQ
Since P is an interior of OZQ, we have that:
\(OZQ = OZP + PZQ\)
Solve for PZQ
\(PZQ = OZQ - OZP\)
Substitute values for OZQ and OZP
\(PZQ = 125 - 62\)
\(PZQ = 63\)
A residual is the difference between _______.
Answers
A residual is the difference between "the measured and predicted values of the quantity of interest".
What is residuals?In regression analysis, a residual would be the difference between an observable and anticipated value.
The formula is;
Residual = Observed value – Predicted value
Some key features regarding the residuals are-
The purpose of linear regression would be to quantify the relationship among one or so more predictor variables one and or more response variables. Linear regression selects the line that best "fits" the data, defined as least squares regression line, to do this. This line generates a prediction for every observation in the dataset, however it is improbable that the regression line's prediction would perfectly match its observed value.The residual is the discrepancy between the predicted and the observed value. The residuals for every observation would represent the vertical distance between both the observation as well as the regression line if we plotted the observed values then overlaid the fitted regression line.To know more about the residual, here

how many ways can he form the 8 person committee if the committee contains at least one gryffindor, exactly three ravenclaws, and no slytherins?
Answers
Assuming that we are starting with a pool of 8 people, we can form the committee in 8 different ways. This is because the committee must contain exactly 3 Ravenclaws, 1 Gryffindor, and 4 people from other houses.
First, we will choose 3 Ravenclaws from the 8 people. This can be done in 8 combinations. Then, we will choose 1 Gryffindor from the remaining 5 people. This can be done in 5 combinations. Lastly, we will choose 4 people from the remaining 4 people, which can be done in 4 combinations.
By multiplying the number of combinations, we get for each step, we can conclude that the total number of ways to form an 8-person committee with the requirement is 8 x 5 x 4 = 160. However, since the order of the people in the committee does not matter, this total number is reduced to 8. In conclusion, we can form the 8 person committee with the given requirement in 8 different ways.

find the area of the triangle which has sides ~u = (3, 3, 3), ~v = (6, 0, 6), and ~u −~v.
Answers
The area of the triangle is approximately 27.71 square units.
What is the area of the triangle with sides ~u = (3, 3, 3), ~v = (6, 0, 6), and u −v?We can use the formula for the area of a triangle given two sides and the included angle:
Area = 1/2 * |u| * |v| * sin(theta)
where |u| and |v| are the magnitudes of the vectors, and theta is the angle between them.
First, we can find the magnitude of each vector:
|u| = √(3² + 3² + 3²) = 3√(3)|v| = √(6² + 0² + 6²) = 6√(2)Next, we can find the vector difference ~u - ~v:
~u - ~v = (3-6, 3-0, 3-6) = (-3, 3, -3)
Then, we can find the magnitude of ~u - ~v:
|~u - ~v| = √((-3)² + 3² + (-3)²) = 3√(2)
Now, we can find the angle between ~u and ~v using the dot product:
~u · ~v = (3)(6) + (3)(0) + (3)(6) = 36|~u| |~v| = (3√(3))(6√(2)) = 18√(6)cos(theta) = (~u · ~v) / (|~u| |~v|)= 36 / (18√(6))= 2 / √(6)theta \(= cos^{-1(2\sqrt(6))}\) ≈ 30.96 degrees
Finally, we can plug in the values to find the area:
Area = 1/2 * |u| * |v| * sin(theta)= 1/2 * (3√(3)) * (6√(2)) * sin(30.96)≈ 27.71 square units.Therefor, the area is ≈ 27.71 square units.

In investigating whether stress is a factor in aging, telomere length was measured in women with chronically ill children, and compared to the number of years since the child's diagnosis. Use the following summary data to calculate the correlation coefficient between telomere length and chronocity:
Summary data:
Sum of products: -8.822
Sum of squares for chronicity: 318.817
Sum of squares for telomere length: 2.868
Total sample size: 38
Answers
The calculated correlation coefficient (r) is approximately -0.291.
To calculate the correlation coefficient between telomere length and chronicity, we can utilize the given summary data. The correlation coefficient, often denoted as r, measures the strength and direction of the linear relationship between two variables.
Let's denote the sum of products as Σxy, the sum of squares for chronicity as Σx², the sum of squares for telomere length as Σy², and the total sample size as n.
From the given data, we have the following values:
Σxy = -8.822
Σx² = 318.817
Σy² = 2.868
n = 38
The correlation coefficient (r) can be calculated using the following formula:
r = Σxy / √(Σx² * Σy²)
Substituting the given values into the formula:
r = -8.822 / √(318.817 * 2.868)
Now, let's solve this equation step by step:
First, multiply the values inside the square root:
r = -8.822 / √(913.350956)
Next, calculate the square root:
r = -8.822 / 30.219307
Finally, divide Σxy by the square root of the product of Σx² and Σy²:
r ≈ -0.291

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
A straight line is shown and is marked with three angles. The first angle measures 60 degrees. The second angle measures 60 degrees. The third angle is labeled y. The line between the 70 degree angle and angle y extends below the straight line. The angle formed is labeled angle x.
Write and solve an equation to determine the measure of angle x. (5 points)
Your answer:
Answers
Since angle y and angle x form vertical angles, the measure of angle x is equal to 50°.
What is the vertical angles theorem?In Geometry, the vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.
Furthermore, the sum of the angles on a straight line is equal to 180. Therefore, we would sum up all of the angles as follows;
60° + 70° + y = 180°
130° + y = 180°
y = 180° - 130°
y = 50°
Since both angle x and angle y are vertical angles, we can logically deduce that they are congruent and as such the magnitude of angle x is equal to 50°.

Suppose the following equations describe a scenario involving an externality: MSB=MPB=12−0.5Q
MSC=2+1.5Q
MPC=2+0.5Q
1. What kind of externality (positive or negative) is this? How do you know? 2. Sketch a graph of the marginal cost and benefit curves for this scenario. 3. Compute the quantity that will result from private decision-making. Show your work. 4. Compute the quantity that would be best from society's viewpoint. Show your work. 5. How do the social and private optima compare? Why is this the expected result in the presence of this type of externality?
Answers
The presence of a negative externality causes the MSC to be higher than the MSB, which leads to the market over-producing the good. This is because producers are only taking their private costs and benefits into account, not the costs and benefits to society as a whole. The difference between the private and social optima is known as the deadweight loss. In this case, the deadweight loss is equal to the shaded triangle in the attached image.
1. This is a negative externality. We can see this by the MSC being higher than the MSB. This means that the cost to society of producing the good is higher than the benefit to society, resulting in the market over-producing the good.2. See the attached image. 3. At private decision making, we set the MSB equal to the MPC: 12-0.5Q = 2+0.5Q. Solving for Q gives Q = 8. 4. To find the socially optimal quantity, we need to set MSB equal to MSC: 12-0.5Q = 2+1.5Q. Solving for Q gives Q = 4. 5. The private and social optima are different because of the negative externality.
