Answer:
So for the geometric mean, you would multiply the two numbers and put them under a radical
Step-by-step explanation:
3 times 10= 30

The solution is : the geometric mean between 3 and 10 is √30.
What is geometric mean?The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.

in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \

Answer: Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope.
Step-by-step explanation:
Given equations of line:
y = 2x – 6 ...(i)
y = –4x + 3 ...(ii)
On comparing with y=mx+c (slope-intercept form), where m= slope ,= y-intercept.
(i) has positive slope (2) and (ii) has negative slope(-4).
Eliminate (ii) from (i), we get

⇒ 6x=9
⇒ [tex]x=\dfrac32[/tex]
Put value of x in (i), we get

The semicolon in (A; β) signifies the ordered pair is polar coordinates (magnitude; angle). The comma in (x, y) signifies the ordered pair is rectangular (Cartesian) coordinates. This notation is borrowed from the GeoGebra app, a geometry graphing/calculating program. It avoids some confusion.

Evaluate and simplify the following complex fraction.
Answers
=========================================================
Explanation:
The fraction 6/(-7) is the same as -6/7
We have the two fraction -6/7 and 3/11 being divided
The denominators are 7 and 11 respectively.
The LCM of those two numbers is 77 since 7*11 = 77
If we multiply each of those fractions (-6/7 and 3/11) by 77, then we'll clear out those inner denominators to simplify this complex fraction into a nicer one.
77*(-6/7) = -66
77*(3/11) = 21
This means the original complex fraction becomes -66/21
We can further simplify this by dividing each part by the GCF 3
-66/3 = -22
21/3 = 7
Therefore, the final answer is -22/7

y = 12(x)+28
(-1,16)
y = 12(-1)+28 = 16
(5,88)
y = 12(5)+28 = 88
Answer:
We conclude that the function [tex]f(x) = 12x + 28[/tex] works.
The graph of the function y = 12x + 28 is also attached below.
Step-by-step explanation:
Given that the line passes through the points
(-1, 16)(5, 88)Let us determine the slope between (-1, 16) and (5, 88) using the slope formula
[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case:
(x₁, y₁) = (-1, 16)(x₂, y₂) = (5, 88)so subtituting (x₁, y₁) = (-1, 16) and (x₂, y₂) = (5, 88) in the slope formula
[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{88-16}{5-\left(-1\right)}[/tex]
Refine
[tex]m=12[/tex]
Thus, the slope of the line is: m = 12
Important Tip:
The slope-intercept form of the line equation is
[tex]y = mx + b[/tex]
where m is the slope and b is the y-intercept
now substituting m = 12 and the point (-1, 16) in the slope-intercept form of the line equation
[tex]y = mx + b[/tex]
[tex]16 = 12(-1) + b[/tex]
switch the equation
[tex]12(-1) + b = 16[/tex]
[tex]-12 + b = 16[/tex]
Add 12 to both sides
[tex]-12+b+12=16+12[/tex]
Simplify
[tex]b=28[/tex]
Thus, the y-intercept of the line is: b = 28
now substituting m = 12 and b = 28 in the slope-intercept form of the line equation
[tex]y = mx + b[/tex]
[tex]y = 12x + 28[/tex]
Thus the equation of the line is:
[tex]y = 12x + 28[/tex]
or
[tex]f(x) = 12x + 28[/tex] ∵ [tex]y = f(x)[/tex]
Hence, we conclude that the function [tex]f(x) = 12x + 28[/tex] works.
The graph of the function y = 12x + 28 is also attached below.

What is Inequality?Relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is -2z - 3 < 5
Minus two times of z minus three less than five.
-2z - 3 < 5
We need to solve this inequality, which means we need to solve of variable z.
Add 3 on both sides of inequality
-2z<8
Divide both sides by 2

Answers
Answer:
For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.
Step-by-step explanation:
The probability of selecting 2 blue marbles without replacement will be 1/66.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
There are 4 white marbles, 6 red marbles, and 2 blue marbles.
Once a marble is selected, it is not replaced.
Then the total number of the marbles will be
Total marbles = 4 + 6 + 2
Total marbles = 12
Then the probability of selecting 2 blue marbles without replacement will be
P = 2/12 x 1/11
P = 2/132
P = 1/66
