Complete the sentence: An unbiased estimator is _____. a. any sample statistic used to approximate a population parameter b. a sample statistic, which has an expected value equal to the value of the population parameter c. a sample statistic whose value is usually less than the value of the population parameter d. any estimator whose standard error is relatively small
Answer:
a) Any sample statistic used to approximate a population parameter.
Step-by-step explanation:
An unbiased estimator is any sample statistic used to approximate a population parameter.
In mathematics, the bias of an estimator refers to the difference between the true value of the parameter being estimated and the estimator’s expected value.
If a statistic is not an underestimate or overestimate of the population parameter, then it is unbiased.
That is why an unbiased estimator is an accurate sample statistic used to approximate a population parameter.

The maximum grain yield for corn is achieved by planting at a density of 36,000 plants per acre. A farmer wants to maximize the yield for the field represented on the coordinate grid. Each unit on the coordinate grid represents one foot. How many corn plants, to the nearest thousand, does the farmer need? (Hint: 1 acre = 43,560 ft2)
Answer:501,000

A circle with a radius of 1 in. is inscribed in a right triangle with legs of 3 in. and 4 in. If a point is randomly chosen within the triangle, what is the probability that the point is NOT also in the circle?
Answer:
P = (6-π)/6Explanation:
Circle Area:
CA = 1²×π
CA ≈ π in²
Triangle Area:
TA = 3×4/2 = 6 in²
Probability:
P(point not in circle) = (6-π)/6 ≈ 0.48 ≈ 47.64%
Solve for x. Round all answers to the nearest tenth.

X
12
Answer:
I hope im right so so sorry if im not
Step-by-step explanation:
first find area
1/2 bh
1/2 of base times height
bh=(9)(12)=108
if there is a right angle then that is 90°
so do 108° -90° which is 18°
So your answer is 18°
The solution is, the value of x = 36.87.
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
from the given figure,
we get,
height = 9
base = 12
by, using the trigonometric relations,
we get,
tan x = 9/12
or, tan x = 0.75
or, x = 36.87
Hence, The solution is, the value of x = 36.87.

Regis was competing on a game show, and he ran into a losing streak. First, he bet half of his money on one question and lost it. Then he lost half of his remaining money on another question. Then he lost $300 on another question. Then he lost half of his remaining money on another question. Finally, he got a question right and won $200. At this point, the show ended, and he had $1,200 left. How much did he have before his losing streak began
Answer:
$9200
Step-by-step explanation:
Given :
Working backwards :
Amount left before last $200 winning = $1200 - $200 = $1000
Amount had before 4th bet loss : $1000 * 2 = $2000
Amount lost on third bet loss = $300
Total amount had before 2nd bet loss = $(2000 + 300) = $2300
Amount had before second loss = 2 * 2300 = $4600
Amount had before first bet loss = $4600 * 2 = $9200
Hence, amount had before starting to lose games is $9200
30 + q = 43 show work PLEASEE HELP
Answer:
13
Step-by-step explanation:
43 - 30 = 13
q = 13
Answer:
q=13
Step-by-step explanation:
first, subtract 30 from both sides of the equation
30-30+q=43-30
you should be left with q=13
that's your answer

Answer:
5x + 3y = 12
Step-by-step explanation:
We are given the line 5x + 3y = 6 and are to find the equation of a new line that is parallel to this one and goes through (3, -1).
Parallel lines have the same slope. The slope of the given line is determined by the coefficients 5 and 3 visible above. Therefore, the form of the equation of the new line is 5x + 3y = C, where we must determine the value of C.
Substitute 3 for x and -1 for y in 5x + 3y = C, obtaining: 5(3) + 3(-1) = C. Then 15 - 3 = 12 is the constant value, and the equation of the 'new line' is
5x + 3y = 12
solve the equation f/3+22=17
Answer:
f = -15
Step-by-step explanation:
f/3 + 22 - 22 = 17 - 22
f/3 + 0 = -5
f/3 = -5
f = 3 × (-5)
f = -15
Thus, The answer is -15

Answer:
The Bakery will sell 22 more vanilla cupcakes than lemon cupcakes.
Step-by-step explanation
Ruling out the answers here, with the first answer you can get that by looking at the graph and can be supported with the data set. With the third answer that can also be supported by the data set and is a educated prediction. And for the fourth answer same thing as the last ones. The only one that wouldn't make sense if you were trying to support it with the data of cupcakes would be the second answer. Which therefore should be your answer.

Regina rolls a fair, six-sided die every week, and her allowance for that week is twice the
number she rolls on the die. Write an expression to represent Regina's allowance for the
week where n represents the number that Regina rolls on the die that week.
Write your answer in the box.
Answer:
6*2=n
Step-by-step explanation:
Well, if its a 6 sided die, and she gets twice the amount, then 6*2 and since the total = n 6*2=n The Total of the equation would be 12 instead of n
