parameters are group of answer choices numerical characteristics of a sample. numerical characteristics of a population. the averages taken from a sample. numerical characteristics of either a sample or a population.
The correct answer is Option B. Parameters are defined as a group of numerical characteristics of a population.
Parameters are generally the numbers or values that represent the whole population's numerical characteristics. There is a difference between Statistics and Parameters.
Statistics is generally defined as the numerical characteristics of a sample. For example, a sample of standard mean or a sample of standard deviation is an example of statistics.
Parameters are the numerical representation of the characteristics of a population. For example, Population mean or Population standard deviation are examples of Parameters. These represent the data or the characteristics of the population in numerical.
Hence, the correct answer is Option B.

The correct answer is Parameters are described as a group of numerical characteristics of a population.
In general, Parameters are the numerical values that represent the entire population's numerical characteristics. There is a variation between Statistics and Parameters. Statistics are defined as the numerical characteristics of a sample. A sample of standard mean deviation or a sample of standard deviation are examples of statistics.
Parameters are the numerical portrayal of the characteristics of a population. Population mean deviation or Population standard deviation are examples of Parameters. These depict the information or the characteristics of the population in a numerical way.

How to solve Binomial Probability Distribution?The formula for binomial probability distribution is;
P(r) = nCr * p^(r) * (1 − p)^(n − r)
Where;
n = Number of events
r = Number of successful events in the trials
p = Probability of success in the single trial of the events
We are given;
p = 80% = 0.8
n = 7
1) Probability that exactly 4 flights are selected is;
P(X = 4) = ⁷C₄ * 0.8⁴ * (1 − 0.8)^(7 − 4)
P(X = 4) = ⁷C₄ * 0.8⁴ * 0.2³
P(X = 4) = 0.11469
2) The probability that at most 3 flights are on time is;
P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
Solving using online binomial calculator gives;
P(X ≤ 3) = 0.99533

Find the equation of the line that is parallel to this line and passes through the point (5, 3).
Find the equation of the line that is perpendicular to this line and passes through the point (5, 3).
Note that the ALEKS graphing calculator may be helpful in checking your answer.
Equation of parallel line:
Equation of perpendicular line:
Step-by-step explanation:
the equation
y = -8/5 x + 6
tells us 2 things :
-8/5 is the slope of the line, 6 is the y-intercept (the y value when x = 0).
a parallel line has the same slope (just a different y-intercept) : -8/5
a perpendicular line (intercepts at 90°) turns the original slope upside-down and flips the sign : 5/8
we the use the given point as x and y values and calculate the y-intercepts.
parallel :
3 = -8/5 × 5 + y-intercept = -8 + y-intercept
11 = y-intercept
y = -8/5 x + 11
perpendicular :
3 = 5/8 × 5 + y-intercept = 25/8 + y-intercept
(3×8)/8 = 24/8 = 25/8 + y-intercept
-1/8 = y-interceot
y = 5/8 x - 1/8 = 1/8 × (5x - 1)

The measurement of a quantity requires units to be defined. The 6 ounce of raisins is equal to 171100 milligrams of it.
What is Measurement unit ?A measurement unit is unit to measure different quantities such as mass, length and time.
The measurement unit of one quantity can be converted into the other by multiplying it with a certain number.
Given that,
The amount of raisins is 6 ounces.
Since One ounce is equal to 23.85 grams,
6 ounce converted in grams equals 6 × 28.35 = 171. 10 grams
Now, 1 gram = 1000 milligrams.
Therefore, 171. 10 grams = 171.10 × 1000 milligrams

x = -1 is the solution to the given inequality |x| - 2 ≤ -3.
The five steps to resolving inequalities are as follows?
When addressing an inequality, we can:
Equal numbers are added to both sides.Take the same amount away from both sides.Add the same positive number to both sides.Subtract the same positive value from both sides.Reverse the sign and multiply both sides by the same negative value.Isolate the variable on one side of the inequality and place all other constants on the other. To achieve this, alter the inequality by performing opposing procedures. First, multiply each side by two to isolate the x. Any action you take toward one side must also be taken toward the other.
C) If x = -1,
|x| - 2 ≤ -3
|-1| - 2 ≤ -3.
1 - 2 ≤ -3.
-1 ≤ -3 which is true.

Using the probability, the expected number of female children in a family with three children is 1.5. The option 2 is correct.
In the given question, we have to find the expected number of female children in a family with three children.
The possibility of having girls in family is 0,1,2 or 3.
From the 8 possible sequences, only one of them give the possibility of 0 girls.
So the probability of 0 girls is 1/8.
There are total 3 ways of having 1 girl.
That is: GBB, BGB, and BBG.
Thus, the probability of 1 girl is 3/8.
Similarly checking for having 2 girls with probability 3/8
Having 3 girls with probability 1/8.
The predicted number of girls is calculated as a weighted average of all potential numbers, where a number's weight is determined by its likelihood of occurring.
The anticipated number of girls is therefore
= 1/8⋅0+3/8⋅1+3/8⋅2+1/8⋅3
= 0+3/8+6/8+3/8
=(3+6+3)/8

The dimensions of a rectangular garden are 15 yards by 20 yards. A sidewalk, one yard wide, is to be built around the outside of the garden. What will be the area of the sidewalk?
Answer:
74 square yards
Step-by-step explanation:
Area of two-dimensional shapes:Area of rectangular garden:
l = 20 yds
w = 15 yds
Area of the rectangular garden = l *w
= 20 * 15
= 300 square yards.
Area of the outer rectangle (rectangular garden and the sidewalk):
length = 20 + 1 + 1 = 22 yds
width = 15 + 1 + 1 = 17 yds
Area of outer rectangle = 22 * 17
= 374 square yards
To find the area of the sidewalk, subtract the area of rectangular garden from the outer rectangle.
Area of the sidewalk = area of outer rectangle - area of sidewalk
= 374 - 300

Step-by-step explanation:
It is because in the elimination method it does not matter whether you eliminate x or y so if you use option a which multiplies -2 by 1st equation so it will become:
-4x+6y=40
4x+6y=8
so the -4x and 4x cancels and a is a valid option.
If you use the b which multiplies the second with 3 it becomes:
2x-3y=-10
4x+3y=24
so -3y and 3y cancel which also makes this a valid option.
