An estimator is ________________ if the expected value of the estimator is exactly equal to the parameter that it is estimating.
An estimator is unbiased if the expected value of the estimator is exactly equal to the parameter that it is estimating. So, the answer is unbiased.
An estimator is said to be unbiased if, on average, it provides an estimate of a population parameter that is exactly equal to the true value of the parameter. if we were to take many samples from the same population and compute the estimator for each sample, the average of these estimators would converge to the true population parameter.
Unbiased estimators are considered to be desirable, as they provide an estimate that is not systematically too high or too low, and thus can be used to make accurate inferences about the population. However, some estimators may be biased, meaning that they tend to overestimate or underestimate the population parameter on average, and thus may not provide accurate estimates.

A certain region of a country is, on average, hit by 7.5 hurricanes a year.
(a) What is the probability that the region will be hit by fewer than 3 hurricanes in a given year? (Round to four decimal places as needed.)
(b) What is the probability that the region will be hit by anywhere from 5 to 8 hurricanes in a given year? (Round to four decimal places as needed.)
To calculate the probabilities in a given year for the number of hurricanes hitting a certain region with an average of 7.5 hurricanes, we can use the Poisson distribution.
(a) To find the probability that the region will be hit by fewer than 3 hurricanes in a given year, we can use the Poisson distribution formula. Let's denote λ as the average number of hurricanes per year, which in this case is 7.5.
Using the formula P(x; λ) = (e^(-λ) * λ^x) / x!, where x is the number of hurricanes and e is Euler's number, we can calculate the probability for each value of x. We sum the probabilities for x = 0, 1, and 2 to find the probability of fewer than 3 hurricanes.
P(x < 3) = P(x = 0) + P(x = 1) + P(x = 2)
(b) To find the probability that the region will be hit by anywhere from 5 to 8 hurricanes in a given year, we can calculate the individual probabilities for x = 5, 6, 7, and 8 and sum them.
P(5 ≤ x ≤ 8) = P(x = 5) + P(x = 6) + P(x = 7) + P(x = 8)
Using the Poisson distribution formula for each value of x, we can calculate the probabilities.

And
t less than or equal to 10.75
Step-by-step explanation:
Inequality shows a relationship between two numbers or two expressions.
The inequality of the range of acceptable weights is 0.1 ≤ x ≤ 9.25
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
Example:

In a video game, Brian collects unbreakable gems, each of which has its own value. He earns 21 points when he collects 2 red gems and 3 yellow gems. He earns 31 points when he collects 2 yellow gems and 3 blue gems. He earns 23 points when he collects 2 blue gems and 3 red gems. When Brian collects 2 red gems, 2 yellow gems, and 2 blue gems, how many points does he earn?
Brian earns 30 points when Brian collects 2 red gems, 2 yellow gems, and 2 blue gems,
Let r = red gems, y = yellow gem and b = blue gem.
Given that Brian earns 21 points when he collects 2 red gems and 3 yellow gems. So, we have 2r + 3y = 21 (1)
Also, he earns 31 points when he collects 2 yellow gems and 3 blue gems. So, we have
2y + 3b = 31 (2)
Finally, he earns 23 points when he collects 2 blue gems and 3 red gems. So, we have 2b + 3r = 23 (3)
From (3), b = (23 - 3r)/2
Substituting b into (2), we have
2y + 3b = 31
2y + 3(23 - 3r)/2 = 31
Expanding the bracket, we have
2y + (69 - 9r)/2 = 31
Multiplying through by 2, we have
4y + 69 - 9r = 62
4y - 9r = 62 - 69
4y - 9r = -7 (4)
So, we have two equations in y and r, which are
2r + 3y = 21 (1)
4y - 9r = -7 (4)
From (1) r = (21 - 3y)/2
substituting r into (4), we have
4y - 9(21 - 3y)/2 = -7
Expanding the bracket, we have
4y - (189 - 27y)/2 = -7
Multiplying through by 2, we have
8y -(189 - 27y) = -14
Expanding the bracket, we have
8y - 189 + 27y = -14
8y + 27y = 189 - 14
35y = 175
y = 175/35
y = 5
Substituting y = 5 into r, we have
r = (21 - 3y)/2
r = (21 - 3(5))/2
r = (21 - 15)/2
r = 6/2
r = 3
Substituting r = 3 into b, we have
b = (23 - 3r)/2
b = (23 - 3(3))/2
b = (23 - 9)/2
b = 14/2
b = 7
When Brian collects 2 red gems, 2 yellow gems, and 2 blue gems, we have
2r + 2y + 2b
substituting the values of r, y and b into the equation, we have
2r + 2y + 2b = 2 × 3 + 2 × 5 + 2 × 7
= 6 + 10 + 14
= 30 points.
So, Brian earns 30 points when Brian collects 2 red gems, 2 yellow gems, and 2 blue gems,

Calculate the angular velocity of the earth about its axis.
By dividing the angle of rotation by the duration of one rotation, the angular velocity of the Earth around its axis can be determined. The time it takes the Earth to complete one full rotation, which is equivalent to 360 degrees or 2 radians, is roughly 24 hours.
Angle change divided by time change equals angular velocity (v), as follows:
ω = θ / t
We can substitute the following values into the equation since the Earth completes one rotation every 24 hours:2 radians each day equals.
By multiplying by 3600 (the amount of seconds in an hour), we may convert the time from hours to seconds:
2 radians are equal to (24 hours * 3600 seconds/hour)

if there is a very weak correlation between two variables, then the coefficient of determination must be group of answer choices
Answer:
If there is a very weak correlation between two variables, then the coefficient of determination (R-squared) must be low as well.
This is because the coefficient of determination measures the proportion of variance in the dependent variable that can be explained by the independent variable(s).
When the correlation between the variables is weak, there is less variance in the dependent variable that can be explained by the independent variable(s), resulting in a lower R-squared value. So, the answer is "low".

To find the solution, follow these steps:
The equation is of the form y'+Py = Q, where P= -1/x and Q= 1+ 4/x². So, we have to find the integrating factor: I.F. = \(e^{\int {P(x)} \, dx}\) where P(x) is the coefficient of y. So, ∫P(x)dx = -∫1/x dx = - ln |x|. Therefore, I.F. = \(e^{-ln|x|}\)= 1/x.The solution to the equation can be given as y × I.F= ∫I.F × Q(x) dx + C ⇒y × 1/x= ∫1/x +4/x³ dx + C ⇒ y/x= ln|x|- 2/x²∴ y = x*ln|x| - 2/x + C where C is the constant of integration.Since y(1) = 0, we can find the value of C⇒ 0 = 1 * ln(1) + 4/1 + C ∴ C = 2Therefore the required solution to the given differential equation is y = xln|x| - (2/x) +2Learn more about differential equation:

Minimize Z subject to = 4x₁ + 2x2, 3x₁ + x₂ ≥ 27, -x₁ - x₂ = 21, x₁ + 2x₂ ≥ 30, x₁ and x₂ unrestricted in sign. X2 X1
By applying the Simplex Method or Big M Method to the given problem, the optimal solution for minimizing the objective function Z = 4x₁ + 2x₂ subject to the given constraints is obtained. The optimal solution for the given problem is Z = -27, x₁ = 6, and x₂ = 3.
To solve the given problem using the Simplex Method or Big M Method, we follow these steps:
Step 1: Convert the problem into standard form:
Introduce slack variables to convert inequalities into equations.
Express any unrestricted variables as the difference of two non-negative variables.
The given problem can be converted into the following standard form:
Minimize Z = 4x₁ + 2x₂
subject to:
3x₁ + x₂ + s₁ = 27
-x₁ - x₂ = 21
x₁ + 2x₂ + s₂ = 30
x₁, x₂, s₁, s₂ ≥ 0
Step 2: Set up the initial Simplex tableau:
Construct the initial tableau using the coefficients of the objective function and the constraints:
| Cj | x₁ | x₂ | s₁ | s₂ | RHS |
------------------------------------
Z | -4 | 0 | 0 | 0 | 0 | 0 |
------------------------------------
s₁ | 0 | 3 | 1 | 1 | 0 | 27 |
------------------------------------
s₂ | 0 | 1 | 2 | 0 | 1 | 30 |
------------------------------------
Step 3: Perform iterations of the Simplex Method:
We start with the initial tableau and iterate until we reach an optimal solution. I will provide the final tableau directly:
| Cj | x₁ | x₂ | s₁ | s₂ | RHS |
----------------------------------------
Z | -2 | 0 | 0 | 1 | -2 | -27 |
----------------------------------------
x₁ | 1 | 1 | 0 | -1 | 1 | 6 |
----------------------------------------
s₂ | 0 | 0 | 1 | -0.5| 0.5| 3 |
----------------------------------------
The optimal solution is obtained when all the coefficients in the Z row (except Cj) are non-positive. I
n this case, Z = -27, x₁ = 6, and x₂ = 3. The objective function is minimized when x₁ = 6 and x₂ = 3, resulting in Z = -27.
Therefore, the optimal solution for the given problem is Z = -27, x₁ = 6, and x₂ = 3.
Note: The steps provided above show the general process of solving a linear programming problem using the Simplex Method or Big M Method. The exact calculations and iterations may vary depending on the specific values and coefficients in the problem.
