Researchers would like to assess the overall health of white pine trees in a state park. Using a computer program,
the researchers selected 100 random points in the state park and assessed the trees closest to the selected
points. Of the 100 trees selected, 24 showed damage to their lower limbs. Which of the following describes the
sample in this setting?
all white pine trees in the world
the 24 trees that showed damage
the 100 trees checked for damage
all white pine trees in the state park
Anyways,
the sample is the 100 trees checked. Thats cause they checked all 100 and found 24 had damage. Which means they sampled 100 trees out of the whatever amount in the forest.

[SEPARATE QUESTION]
Separate question since people are confused about it in the previous answers comments "Which of the following statements best describes the bias that may arise from the results?":
I can confirm A is wrong. C just, feels wrong completely.
So that leaves us with B or D.
I think it's D: Trees near the road may have more damage than trees away from it, so the results may overestimate the overall damage of the trees.
I have not finished yet but I am 95% sure D is correct.
The reason why I don't believe it's B is because they want to resample near the same road, which can still result to biased results.

ED2021
Among all the given descriptions, the one that is describing the sample in the given setting is: “all white pine trees in the state park.” Hence, Option D is correct.
What is the meaning of the term “sample”?
A sample is merely a subset of the population. Consider a scenario in which one wished to determine the average income for all Americans in the population. In terms of research, a sample is a collection of individuals, things, or things that are taken for measurement from a wider population.
To ensure that the findings from the research sample can be applied to the population as a whole, the sample should be representative of the population. 100 trees that were examined are the sample.
That's because they examined all 100 and discovered that 24 had damage, which means that they took 100 samples from the total number of trees in the forest.
The findings may exaggerate the total extent of the damage to the trees since trees close to the road may have sustained more damage than those farther away from it.
Therefore, Option D is correct.

(6x^2+3x) + (x^2 - 4x -3)
plz help
Answer:
7x^2 - x -3
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
We have to use distributive property first to get rid of the parenthesis, so you simply have to multiply the positive (+) symbol with everything inside the second set of parenthesis.
+ * x^2 = x^2
+ * -4x = -4x
+ * -3 = -3
Now, we rewrite the equation which is
6x^2 + 3x + x^2 - 4x -3
Now you simply combine like terms.
6x^2 + x^2 = 7x^2
3x-4x = -x
The answer will be
7x^2 - x -3

On a coordinate plane, a piecewise function has 3 lines. The first line has a closed circle at (negative 3, negative 4) and continues horizontally to an open circle at (0, negative 4). The second line has a closed circle at (0, 2) and continues horizontally to an open circle at (4, 2). The third line has a closed circle at (4, 3) and continues horizontally through (5, 3) with an arrow instead of an endpoint.
A step function is shown on the graph. What are the domain and range?
Domain:
Range:
Answer:Answer:
f(-2) = 2
f(0) = 3
f (4) = -1
Step-by-step explanation:
The equation of the straight line passing through the points (0,3) and (-4,1) is
⇒ 2(y - 1) = x + 4
⇒ 2y - 2 = x + 4
⇒ 2y = x + 6
⇒
Again, the equation of the line passing through the points (0,1) and (4,-1) is
⇒ - 2 ( y + 1) = x - 4
⇒ - 2y = x - 2
⇒
Therefore, the function is defined as
for x ≤ 0 ........... (1) and
for x > 0 ............ (2)
Therefore, f(-2) = 2 from equation (1).
f(0) = 3 from equation (1)
And f (4) = -1 from equation (2). (Answer)

PLS HELP BY TOMORROW!A dice has sides numbered 1-6. What is the probability of landing of double threes?
Answer:
1/6
The probability of rolling a specific number twice in a row is indeed 1/36, because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6). The probability of rolling any number twice in a row is 1/6, because there are six ways to roll a specific number twice in a row (6 x 1/36).
Answer:
0.46% I think I got it wrong and I'm kinda sure bout it
Step-by-step explanation:
So on any turn, the probability of rolling a double is 6/36 = 1/6. Now each roll of the dice is independent. So the probability that any given turn will result in the rolling of doubles three times in a row is (1/6) x (1/6) x (1/6) = 1/216. This is approximately 0.46%

Mrs.Davis deposits $8,000 into each of 2 savings accounts account 1 earns 6.5% simple interest account 2 earns earns 3% simple interest what’s the difference between the amounts of interest in account 1 and account 2 after 6 years?
Answer:
$1680
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Account 1:
I = (8000)(0.065)(6)
I = $3,120
Account 2:
I = (8000)(0.03)(6)
I = $1,440
$3120 - $1440 = $1680

Triangle A B C. Angle C is 90 degrees. Hypotenuse A B is 41, adjacent B C is 9, opposite A C is 40.
Answer:
bStep-by-step explanation:
we are given opposite, adjacent and hypotenuse
and said to find cos(B)
recall trigonometric identity [tex]\cos(\theta)=\dfrac{adj}{hypo}[/tex]
let adj and hypo be 9 and 41 respectively
so
[tex] \displaystyle \: \cos( \beta ) = \frac{9}{41} [/tex]
