the two branches of the study of statistics are generally reffered to as
Answer:
The correct answer is: descriptive and inferential statistics.
Step-by-step explanation:
The two branches of the study of statistics are generally referred to as descriptive and inferential statistics.
Descriptive statistics are the brief summary statistic which summarizes a given data set, which can be a representation of the entire population or just a sample of it.
While Inferential statistics is the way data analysis is used to deduce the properties of an underlying probability distribution.
The study of statistics generally branches into descriptive statistics, which involves summarizing and displaying data, and inferential statistics, which makes predictions about a population based on sampled data.
Explanation:The two branches of the study of statistics are generally referred to as descriptive statistics and inferential statistics. Descriptive statistics involves the organization, summarization, and display of data. It seeks to describe a situation or sample population without offering any conclusions or inferences about the data. Examples include calculating averages, measures of central tendency like mean, median, mode, and variability measures such as range, variance, and above all standard deviation.
On the other hand, inferential statistics is a method to make predictions or inferences about a population based on a sample of data. It is used when it is not practical or impossible to examine the entire population. Examples of inferential statistics methods include hypothesis testing, chi-square tests, t-tests, ANOVA, regression analysis etc.

Sets L, M, and N are shown. Which of the sets represents L ∪ (M ∩ N) (the union of L with the intersection of sets M and N)?
L = {0, 20, 40, 80, 100}
M = {5, 10, 15, 20, 25}
N = {10, 20, 30, 40, 50}
Answer:
L ∪ (M ∩ N) = {0, 10, 20, 40, 80, 100}
Step-by-step explanation:
L ∪ (M ∩ N) means "take what's common of set M and set N" and then "add it to all the elements of set L".
So, what are the common elements of set M and set N?
They are 10 & 20. So,
M ∩ N = {10,20}
Now, we add it to all the elements of set L. Note that we don't need to count 20 twice.
Thus L ∪ (M ∩ N) = {0, 10, 20, 40, 80, 100}
Katie needs to figure out how much space a shoe box takes up. It is 13 1/2 inches long and 5 inches high and 6 2/3 inches wide. What is the shoe box's volume?
Answer:
you multiply all three of these numbers to get an answer of 450
Step-by-step explanation:
Final answer:
The volume of the shoe box is calculated using the formula for the volume of a rectangular prism, resulting in a total of 450 cubic inches.
Explanation:
The formula for finding the volume of a rectangular prism (which is the shape of a shoe box) is Volume = Length × Width × Height. However, before calculating, we need to ensure all dimensions are in the same unit. Since the given width is in mixed number form, we will convert 6 2/3 inches to an improper fraction which is 20/3 inches. We then multiply the length, width, and height.
Volume = (13.5 inches) × (20/3 inches) × (5 inches)
Volume = (13.5 × 20/3 × 5) cubic inches
Volume = (270/3 × 5) cubic inches
Volume = (90 × 5) cubic inches
Volume = 450 cubic inches
The shoe box's volume is 450 cubic inches.
Which expression is equivalent to –8?
–2–3
(-1/2)^-3
(1/2)^-3
2–3
Answer: second option. (NOTE: If the first option is [tex](-2)^3[/tex], then it would be an equivalent expression too, because: [tex](-2)(-2)(-2)=-8[/tex])
Step-by-step explanation:
To solve this problem you must keep on mind the following exponents rule:
[tex](\frac{1}{a})^-b=a^b[/tex]
Therfore, you have that:
[tex](-\frac{1}{2})^-3=(-2)^3[/tex]
This means that the number -2 must be multiply by itself three times. Therefore, you obtain the folllowing result:
[tex](-2)(-2)(-2)=-8[/tex]
If the first option is [tex](-2)^3[/tex], then it would be an equivalent expression too, because:
[tex](-2)(-2)(-2)=-8[/tex]
Answer:
[tex](\frac{-1}{2})^{-3} = -8[/tex].
Step-by-step explanation:
Given : –8.
To find : Which expression is equivalent.
Solution : We have given –8.
By the radical rule : [tex](\frac{-1}{x})^{-a} = -x^{a}[/tex].
Then
[tex](\frac{-1}{2})^{-3} = -2^{3}[/tex].
[tex](\frac{-1}{2})^{-3} = -8[/tex].
Therefore, [tex](\frac{-1}{2})^{-3} = -8[/tex].
Write the equation of the line in slope-intercept form that has the following points: (2, -1)(5, -3)
Answer:
[tex]\large\boxed{y=-\dfrac{2}{3}x+\dfrac{1}{3}}[/tex]
Step-by-step explanation:
The skope-intercept form:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (2, -1) and (5, -3). Substitute:
[tex]m=\dfrac{-3-(-1)}{5-2}=\dfrac{-3+1}{3}=\dfrac{-2}{3}=-\dfrac{2}{3}[/tex]
We have the equation:
[tex]y=-\dfrac{2}{3}x+b[/tex]
Put the coordinates of the point (2 , -1) to the equation:
[tex]-1=-\dfrac{2}{3}(2)+b[/tex]
[tex]-1=-\dfrac{4}{3}+b[/tex] add 4/3 to both sides
[tex]\dfrac{1}{3}=b\to b=\dfrac{1}{3}[/tex]
Finally we have:
[tex]y=-\dfrac{2}{3}x+\dfrac{1}{3}[/tex]
If a train travels at 80mph for 15 min, what is the distance traveled ?
Answer:
20 miles
Step-by-step explanation:
The formula for distance is
d =rt where r is the rate and t is the time
We need to convert the time to hours since the rate is in mph
15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours
d = (80 mph) * .25 hours
d = 20 miles
The train goes 80 miles in an hour which is 60 minutes. 60 minutes divided by 15 minutes equals 4. 80 miles divided by 4 equals 20 miles. The train went 20 miles in 15 minutes.
Apply the distributive property to factor out the greatest common factor. 30+42= 30, plus, 42, equals
To factor out the greatest common factor from 30 and 42, first, find the GCF. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The greatest common factor is 6. Using the distributive property, 30 + 42 becomes 6(5 + 7). So, the final answer is 6 times the sum of 5 and 7, which is 72.
To factor out the greatest common factor (GCF) from the expression 30 + 42, we first need to find the GCF of the two numbers, which is 6. Then we can rewrite the expression using the distributive property.
Step 1: Find the GCF of 30 and 42:
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The common factors are 1, 2, 3, and 6. The greatest common factor is 6.
Step 2: Rewrite the expression using the GCF:
[tex]\[30 + 42 = 6 \times 5 + 6 \times 7\][/tex]
Step 3: Apply the distributive property:
[tex]\[30 + 42 = 6 \times (5 + 7)\][/tex]
Step 4: Perform the addition inside the parentheses:
[tex]\[30 + 42 = 6 \times 12\][/tex]
Step 5: Multiply:
30 + 42 = 72
So,30 + 42 equals 72 after factoring out the greatest common factor using the distributive property.

if a/b=2 what is the value of 4b/a
Anwer:
4b/a=2
Step-by-step explanation:
Lets assume:
a = 4 & b = 2
So a/b would equal 2.
4b/a indicates that you are going to multiply b times 4, meaning that in this scenario you would multiply 2 times 4.
4(2) = 8
and 8 divided by (4) is 2.
Why 4? Because remember a = 4 (in this scenario).
Other examples:
10/5 = 2, --> 4(5) = 20, --> 20/10 = 2.
20/10 = 2. --> 4(10) = 40, --> 40/20 = 2.
Answer:
2
Step-by-step explanation:
a/b = 2
Invert each side of the equation
b/a = ½
Multiply each side by 4
4b/a = 4 × ½ = 2

Step-by-step explanation:
Prove:Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
A = sinx - sin3x,
B = -sin3x + sin5x
First A:
The average of x and 3x is 2x, and they (x and 3x, that is) are each a distance of x from this average. That's fancy talk for:
x = 2x-x,
3x = 2x+x.
So, A = sin(2x-x) - sin(2x+x)
Using angle sum formulas:
A = (sin2x cosx - cos2x sinx) - (sin2x cosx + cos2x sinx)
A = -2 cos2x sinx
Similarly,
B = -sin(4x-x) + sin(4x+x)
= -(sin4x cosx - cos4x sinx) + (sin4x cosx + cos4x sinx)
B = 2 cos4x sinx
Now,
sinx - 2sin3x + sin5x = A+B = -2 cos2x sinx + 2 cos4x sinx
= 2 sinx (cos4x - cos2x).
Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
Step-by-step explanation:sinx - 2sin3x + sin5x = sinx - sin(3x) + sin(5x)- sin(3x)
= 2· cos[(x+3x)/2] · sin[(x-3x)/2] + 2·cos[(5x+3x)/2]· sin[(5x-3x)/2]
= 2· cos(2x) ·sin(-x) + 2· cos(4x) · sin(x)
= -2·cos(2x)·sinx + 2· cos(4x)·sinx
= 2·sinx · [ cos(4x)- cos(2x)]
Which triangle is a reflection of triangle ABC over the X axis?
The correct answer is: Triangle MNO
A reflection of a triangle over the X-axis involves flipping the triangle about this axis. Each point in triangle ABC (A, B, and C) is reflected to a corresponding point A', B', and C' in the reflected triangle such that their Y-coordinates are negated while the X-coordinates remain the same.
Explanation:To understand the concept of the reflection of a triangle, you need to visualize flipping the triangle over a line, in this case, the X-axis. When a triangle named ABC is reflected over the X-axis, the positions of the points change as follows: A (x, y) becomes A' (x,-y), B (x, y) becomes B' (x, -y), and C (x, y) becomes C' (x, -y). Therefore, the triangle that is a reflection of triangle ABC over the X-axis is triangle A'B'C'.

A veterinarian divided 2/5 of a bottle of medicine equally among some sick cats. She gave each cat 1/5 of a bottle of medicine. How many sick cats were there?
The veterinarian gave each cat 1/5 of a bottle of medicine. By dividing the total medicine (2/5 of a bottle) by 1/5, we find that there were 2 sick cats.
Explanation:To find the number of sick cats, we need to divide the amount of medicine given to the cats by the amount given to each cat. Since each cat received 1/5 of a bottle, we can divide the total medicine (2/5 of a bottle) by 1/5 to find the number of cats. This can be done by multiplying the total medicine by the reciprocal of 1/5, which is 5/1.
Convert 2/5 to an improper fraction: 2/5 = 2 ÷ 5 = 2/5Multiply the total medicine by the reciprocal of 1/5: 2/5 × 5/1 = 2 × 5 / 5 × 1 = 10 / 5 = 2Therefore, there were 2 sick cats.
