The following is the least appropriate measure of central tendency for a data set that contains outliers is 2ndquartile.
A single number that seeks to characterise a set of data by pinpointing the centre position within that set of data is referred to as a measure of central tendency. As a result, measures of central location are occasionally used to refer to measures of central tendency. They also fit within the category of summary statistics. You are probably most familiar with the mean (sometimes known as the average), but there are additional central tendency measures, including the median and the mode.
The mean, median, and mode are all reliable indicators of central tendency, however depending on the situation, some indicators are more useful than others.

Data to predict the count of each bird that will be in the sanctuary during this year's visit is red-tailed hawks, Turkish vultures, northern goshawks and bald eagles.
What does predict mean in math?
In general, prediction is the process of determining the magnitude of statistical variates at some future point of time.
12 + 2 + 4 + 7 = 25 (The total number of birds observed in the last year)
Turkish vultures = 175 × 12 / 25 = 84
bald eagles = 175 × 2 / 25 = 14
northern goshawks = 175 × 4 / 25 = 28
red-tailed hawks = 175 × 7/ 25 = 49
So,
49 ↔ red-tailed hawks
84 ↔ Turkish vultures
28 ↔ northern goshawks
14 ↔ bald eagles
Hence, data to predict the count of each bird that will be in the sanctuary during this year's visit is red-tailed hawks, Turkish vultures, northern goshawks and bald eagles.

To predict the count of each bird that will be in the sanctuary during this year's visit, we need to assume that the proportion of each bird species in the sanctuary remains the same as it was last year when Jeff visited.
Last year, Jeff saw a total of 12 Turkish vultures + 2 bald eagles + 4 northern goshawks + 7 red-tailed hawks = 25 birds.
So, the proportion of each bird species in the sanctuary last year was:
Turkish vultures: 12/25 = 48%
Bald eagles: 2/25 = 8%
Northern goshawks: 4/25 = 16%
Red-tailed hawks: 7/25 = 28%
Using these proportions, we can predict the count of each bird species in the sanctuary this year:
Turkish vultures: 48% of 175 birds = 84 birds
Bald eagles: 8% of 175 birds = 14 birds
Northern goshawks: 16% of 175 birds = 28 birds
Red-tailed hawks: 28% of 175 birds = 49 birds
These are the predicted counts of each bird species in the sanctuary during this year's visit.

The first, second and fourth terms of a proportion are 16, 24 and 54 respectively. Find the third
term.
(a) 8
(b) 36
(c) 24
(d) 7.1
Answer:
Third term is 36
Step-by-step explanation:
According to the definition of proportion, if two sets of given numbers are in the same ratio, then the ratios are said to be directly proportional to each other
We use the symbol :: to denote proportion
So if
a:b :: c:d
Then a/b = c/d
We are given that first number = 16, second is 24 and the last is 54
Let the third number be x
We have that
16:24 :: x : 54
In other words
16/24 = x/ 54
Simplifying left side
2/3 = x/54
x = 2/3 x 54 = 36

Determine b so that f(x)is continuous if
f(x)= {4x+9 x≤2
4x2+bx+1 x≤2
b=
The value of b that makes the function f(x) continuous at x = 2 is b = 4. The complete function f(x) = {4x + 9, x ≤ 2; 4x^2 + 4x + 1, x > 2} is now continuous at x = 2.
How to get the b using continuous function?For a function to be continuous, its value must be the same at the point where two different pieces of the function meet, and the limit of the function must exist at that point.
In this case, we have two different pieces of the function: f(x) = 4x + 9 for x ≤ 2, and f(x) = 4x^2 + bx + 1 for x > 2. To make the function continuous at x = 2, the values of f(x) for x = 2 must be the same for both pieces.
According to question:Let's plug in x = 2 into both pieces:
f(2) = 4 * 2 + 9 = 17 for x ≤ 2
f(2) = 4 * 2^2 + b * 2 + 1 = 8 + 2b + 1 = 9 + 2b for x > 2
Equating these two values, we get:
17 = 9 + 2b
Solving for b:
b = (17 - 9) / 2 = 4
So, the value of b that makes the function f(x) continuous at x = 2 is b = 4. The complete function f(x) = {4x + 9, x ≤ 2; 4x^2 + 4x + 1, x > 2} is now continuous at x = 2.

FILL THE BLANK. the term statistics refers to a set of mathematical procedures for ______, _______, and ________ information
Statistics is a set of mathematical procedures used to collect, analyze, and interpret data.
Generally, it involves collecting data from a sample population, organizing the data into a meaningful manner, and then applying statistical methods to draw conclusions from the data. Statistical methods include descriptive statistics, which summarize the data, and inferential statistics, which use the data to make predictions about a larger population.
Descriptive statistics uses various measures to summarize a population, such as the mean, median, and mode. The mean is the average of all the values in a population and is calculated by adding up all the values and dividing by the number of values. The median is the middle value when all the values in a population are arranged from smallest to largest. The mode is the most frequently occurring value in a population.
Inferential statistics uses the data from a sample population to make predictions about a larger population. For example, a researcher might use a statistical test to determine if a certain treatment is effective. The researcher would collect data from a sample of the population, then use a statistical test to determine if the treatment had an effect on the sample population. If the test is statistically significant, then the researcher can conclude that the treatment is likely to have an effect on the larger population.

A pole 75 meters tall is stabilized using 3 guy wires spaced 120 degrees apart

tower and anchored 30 meters from the base of the tower. During a wind storm
the tower is bent over between two of the guy wires such that the 2 guy wires are
slack but the third is still tight. The angle that the tight wire makes with the
ground is 34 degrees. How far off vertical is the tower?
The amount the tower is off vertical by a height of h=74.13 m
Let's call the distance from the base of the tower to the point where the guy wire is attached "h".
This distance is 40 meters.
The length of the tight guy wire is:
L = h + 30
Using the Pythagorean theorem,
We can find the length of the guy wire as:
L^2 = h^2 + 30^2
Substituting the value of h = 40, we get:
L^2 = 40^2 + 30^2
L^2 = 1600 + 900
L^2 = 2500
L = 50
Next, we use the tangent function to find the angle between the vertical and the tight guy wire:
tan(34) = L/h
50/40 = tan(34)
Solving for h, we find:
h = L/tan(34)
h = 50/tan(34)
Finally, subtracting h from the height of the tower, we find the amount the tower is off vertical:
75 - h = 75 - 50/tan(34)
75-h = 75-(50/ 0.6745)
75-h = 75-74.12

She ran 0.3 miles per hour faster on Thursday than on Wednesday.
What is the relation between velocity, distance and time?Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:
v = d/t.
Considering the time in hours, each hour = 60 minutes, the velocity on Wednesday is given as follows:
v = 6/(50/60)
v = 7.2 miles per hour.
The velocity on Thursday is given as follows:
v = 4/(32/60)
v = 7.5 miles per hour. -> faster, as 7.5 > 7.2.
The difference is of:
7.5 - 7.2 = 0.3 miles per hour.

How do you find the scalar and vector projection?
The scalar and vector projection of a vector onto another vector is found using dot product.
The scalar projection of a vector A onto a non-zero vector B is given by:
scalar projection = (A . B) / ||B||
where (A . B) is the dot product of vectors A and B and ||B|| is the magnitude of vector B.
The vector projection of A onto B is given by:
vector projection = (scalar projection) * (unit vector in the direction of B)
The unit vector in the direction of B is given by B/||B||. A unit vector has a magnitude of 1.

Find the range for the measure of the third side of a triangle when the measures of the other two sides are 22 in. and 17 in.
Answer:
The range for the third side is 11 in. to 40 in.
Step-by-step explanation:
The third side of a triangle must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. In this case, the two sides have lengths of 22 in. and 17 in., so the third side must have a length between 11 in. (the smaller of the two given lengths) and 40 in. (the sum of the two given lengths).
The sum of the first 6 terms of a geometric sequence is 7812. The common ratio is 5. What is the second term of the sequence?.
The second term of the geometric sequence is 1260
The sum of the first 6 terms of a geometric sequence is 7812. This means that the formula for the sum of the first n terms of a geometric sequence, Sn = a(1-r^n)/(1-r), can be used to solve for the first term, a. 7812 = a(1-5^6)/(1-5). Solving for a, the first term is equal to 252.
The common ratio is 5, meaning that each term of the sequence is 5 times the previous term. Therefore, the second term is equal to 252 * 5, or 1260. This can also be seen by looking at the sequence, 252, 1260, 6300, 31500, 157500, 787500.
To conclude, the second term of the geometric sequence is 1260. This was calculated by taking the first term and multiplying it by the common ratio, 5.
