Elena collects 112 specimens of beetle and records their lengths for an ecology research project. When she returns to the laboratory, Elena finds that she incorrectly recorded one of lengths of the beetles as 122 centimeters (about 4 feet). What should she do with the outlier, 122 centimeters, when she analyzes her data?

please help me, this isn't a (a) (b) (c) (d) option I need a full explanation
40 POINTS!!!

Answers

Answer:

The correct option is;

C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording

Step-by-step explanation:

In order to minimize error in measurement, some valuable steps includes;

1) Perform a double check on all measurements to ensure that the measurements recorded are accurate

2) Ensure proper training before taking measurements

3) Measurements should only be taken under controlled conditions

4) Separate the entire population into smaller groups for proper recording

5) Have a second observer double check the records

Elena should remove the outlier of 122 centimeters (about 4 feet) from her dataset during data analysis due to its significant deviation from the typical lengths of beetles.

When analyzing her data, Elena should consider removing the outlier of 122 centimeters (about 4 feet) from her dataset. The Outlier is defined as a "data-point" which significantly deviates from the overall-pattern of the data.

In this case, the recorded length of 122 centimeters is likely an error or anomaly, as it is much larger than the typical lengths of beetles. Removing the outlier will help ensure that her analysis and conclusions accurately reflect the majority of the data and the actual behavior of the beetles.

Given that a randomly chosen flight arrives in Atlanta (ATL), what is the probability that it arrives on time?

Answers

Using the given percentage, it is found that there is a 0.877 = 87.7% probability that it arrives on time.

A probability is the number of desired outcomes divided by the number of total outcomes.Over a large sample, a percentage can be interpreted the same as a probability.

In this question, over a large number of flights, 87.7% arrive on time in Atlanta. Hence, there is a 0.877 = 87.7% probability that it arrives on time.

Here is what the plane would look like if the figure and points were drawn.

Answer:

52 units

Step-by-step explanation:

Plot the points and connect.

Note. If you connect the points in the given order you will end up with a weird figure hence we connect as pictured.

Horizontal sides sum to:

2*(8  - (-7)) = 2*15 = 30

Vertical sides sum to:

2*(8  - (-3)) = 2*11 = 22

The perimeter is:

Farmer Hopt started with some alabers on her farm. She had 90 alabers after 5 months. After 16 months, she had 167 alabers. Assume a constant rate of change.

Write an equation in slope-intercept form for total alabers, y, after x months.

Answers

Answer:

[tex]y= 11x+35[/tex]

Step-by-step explanation:

Let's find the slope first. It took hopt 11 months (from 5 to 16) to grow 77 trees. It means that each month he grew [tex]\frac{77}{11} = 7[/tex] trees.

At this point you can use the point-slope form and re-write the equation or, let's think about it. It's a direct proportion. If at month 5 she has 90 trees, one month earlier she had 11 less. two month earlier, 22 less. 5 month earlier, or at x = 0 (ie, our intercept!) she had 55 less trees, or 90-55 = 35 trees

The equation is then [tex]y= 11x+35[/tex]

A: 250 = 3 c - 20
B: 250 = 20 - 3 c
C: 250 = 3 - 20 c
D: 250 = 20 c - 3

Answers

Answer:  A: 250 = 3c - 20

Three times a number is three more than twice the number. Which equation can be used to find the value of x, the unknown number? 3x = 3 2x x = 3 2x 3x 3 = 2x 3x = 3 2 x.

Answers

We can begin by assigning a variable to the unknown number; in this case a number. Let's call this unknown number x (as that is the variable that the answer choices are given in terms of). Once we have our variable, we can begin to translate the written problem into numbers.

"Three times a number" implies multiplication of x by 3.
"is" indicates an = sign.
"three more" implies addition of 3.
"twice the number" can be translated to multiply x by 2.

Adding all of these together we get 3x=3 + 2x.
