What is the definition of independent samples? A. All samples of the same size have an equal chance of being selected from the population. B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population. C. The sample selected from one of the populations is paired with a sample selected from the other population.
Answer:
B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
Step-by-step explanation:
In statistical analysis, the use of independent samples for diverse studies is common.
Independent samples are such that the sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
This means that samples are selected randomly in such a way that an observation obtained from a sample does not depend on the values obtained from the observation of another sample from the other population.

Determine the slope of the line that is perpendicular to the line passing through the points (-6, 4) and (10,-2).
Answer:
The slope of the line that is perpendicular is 3/8
Step-by-step explanation:
The slope of the line through
(-6,4) (10,-2)
m = ( y2-y1)/(x2-x1)
= ( 10 - -6)/( -2 -4)
= (10+6)/(-2-4)
= 16/-6
=-8/3
A line perpendicular has a slope that is the negative reciprocal
- 1/( -8/3)
+ 3/8
The slope of the line that is perpendicular is 3/8

what is the range of f?
Answer:
Range is [tex]-5 \le y \le 5[/tex]
Range in interval notation is [-5, 5]
==========================================================
Explanation:
Refer to the diagram below. As marked in red, the smallest y value is y = -5. The largest y value is y = 5. The range is the set of y values between these endpoints, including both endpoints.
We can say the range is [tex]-5 \le y \le 5[/tex]
In interval notation, we write that as [-5, 5]. The use of square brackets tells the reader that the endpoints are included as part of the range.

Find the surface area of this sphere.
Round to the nearest tenth.
10 cm
Formulas for Spheres
S.A. = 4rr2
V = firer
?] cm2
Enter
Answer:
the answer is 62.8cm^2
Step-by-step explanation:
4•3.14•5
By using the formula for the surface area of the sphere [tex]S.A = 4 \pi r^2[/tex], the surface area of this sphere would be, [tex]S.A = 314[/tex] cm²
Used the formula of the surface area of the sphere,
[tex]S.A = 4 \pi r^2[/tex]
Where 'r' is the radius of the sphere.
Given that,
Diameter of a sphere = 10 cm
We know that the radius of the sphere is half of the diameter of the sphere.
Hence, the radius of the sphere is,
[tex]r = \dfrac{10}{2}[/tex]
[tex]r = 5[/tex] cm
Substitute r = 5 cm in the above formula,
[tex]S.A = 4 \pi r^2[/tex]
[tex]S.A = 4 \times 3.14 \times 5^2[/tex]
Therefore, the surface area of a sphere is,
[tex]S.A = 314[/tex] cm²

Answer:
48°60°72°Step-by-step explanation:
The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:
4×12° : 5×12° : 6×12° = 48° : 60° : 72°
Angles 1 to 3 are 48°, 60°, 72°, respectively.

Answer:
([tex]\frac{5}{2}[/tex], 3)
Step-by-step explanation:
I got 5/2 as my x variable and 3 for my y variable to being the midpoint. In which I added both my x variables provided ( 3 and 2 ) and then I divided them by two to get half of that (since you are looking for in between those two digits technically so you are wanting to find the midpoint or the middle of that line segment). I also did the same with the two y variables as well which were 7 and -1, then I divided both by two to get the variable 3.
Answer:
5/2, 3

Answer:
[tex]57\frac{3}{11}[/tex] = c
or
[tex]57.\overline{27}[/tex] = c
Step-by-step explanation:
We know that the diameter of a circle multiplied by [tex]\pi[/tex] is the circumference, so we can create this equation:
180 = c * [tex]\pi[/tex]
Your teacher told us to assume [tex]\pi[/tex] is 22/7, so we'll put that in
180 = c * [tex]\frac{22}{7\\}[/tex]
To get c by itself, we divide both sides by 22/7
[tex]\frac{180}{\frac{22}{7}}[/tex] = c
Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22
180 * [tex]\frac{7}{22}[/tex] = c
Evaluate
[tex]\frac{1260}{22}[/tex] = c
[tex]57\frac{3}{11}[/tex] = c
If you want a decimal instead:
[tex]57.\overline{27}[/tex] = c

O x=5+31
O x = 51/19
O x = 5+219
O x = 5+2/31
Answer:
[tex]x = 5 \± \sqrt{31}[/tex]
Step-by-step explanation:
Given
[tex]6 = x^2 - 10x[/tex]
Required
The solution in radical form
[tex]6 = x^2 - 10x[/tex]
Rewrite as:
[tex]x^2 - 10x - 6 = 0[/tex]
Using the quadratic formula, we have:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
a = 1
b = -10
c = -6
So, we have:
[tex]x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{100 +24}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{124}}{2}[/tex]
Split the roots
[tex]x = \frac{10 \± \sqrt{4 * 31}}{2}[/tex]
Express [tex]\sqrt 4[/tex] as 2
[tex]x = \frac{10 \± 2\sqrt{31}}{2}[/tex]
Split the fraction
[tex]x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}[/tex]
[tex]x = 5 \± \sqrt{31}[/tex]
