The value of x that is not in the domain is x = 7.
which of the following values of X is not in the domain of f(x)?
Remember that in math we can't divide by zero, so any value that makes the denominator equal to zero can't be in the domain.
Here the rational function is:
f(x) = (x + 3)/(x - 7)
When x = 7, the denominator becomes zero, so x = 7 is not in the domain.

Step-by-step explanation:
[tex]\text{The formula of a volume of a sphere:}\\\\V=\dfrac{4}{3}\pi R^3\\\\R-radius\\\\\text{A diameter}\ D=2R\Rightarrow R=\dfrac{D}{2}.\\\\\text{Therefore}\\\\V=\dfrac{4}{3}\pi\left(\dfrac{D}{2}\right)^3=\dfrac{4}{3}\pi\left(\dfrac{D^3}{8}\right)=\dfrac{D^3}{6}\pi[/tex]
[tex]\text{We have the dimater}\ D=10in.\ \text{Substitute:}\\\\V=\dfrac{10^3}{6}\pi=\dfrac{1000}{6}\pi=\dfrac{500\pi}{3}\ in^3[/tex]
For this case we have that by definition, the volume of a sphere is given by:
[tex]V = \frac {4} {3} \pi * r ^ 3[/tex]
Where:
r: It is the radius of the sphere
We are told as data that the diameter of the sphere is 10in, so the radius is 5in:
[tex]V = \frac {4} {3} \pi * 5 ^ 3\\V = \frac {4} {3} \pi * 125\\V = \frac {500} {3} \pi\\V = 523.33in ^ 3[/tex]
Answer:
[tex]V = \frac {4} {3} \pi * 5 ^ 3\\V = \frac {4} {3} \pi * 125\\V = \frac {500} {3} \pi[/tex]
Any of the three given expressions can be used to find the volume of the sphere.

Which of the follow if best describes AOR
Answer:
C
Step-by-step explanation:
A major arc is an arc that is greater than 180 degrees.
A minor arc is an arc less than 180 degrees.
An acute angle is an angle less than 90 degrees.
A central angle is the angle created in the center of a circle with 2 sides being the radius.
Thus, we can see in the figure that we are talking about the angle so we can eliminate major arc and minor arc.
Now, we clearly see that the angle is greater than 90 degree so it cannot be acute angle.
The correct answer is central angle as it goes with the definition.
Final answer:
AOR or Adjusted Odds Ratio is used in medicine as a measure of association between exposures and outcomes, and it tends to overestimate the RR for common diseases.
Explanation:
The term AOR refers to the Adjusted Odds Ratio, which is a statistical measure used to describe the strength of association or non-independence between two binary data values in epidemiology and other fields. In comparison to the Relative Risk (RR), the AOR is a more complex measure that takes into account additional variables that may affect the outcome. In the context of disease prevalence, when a disease is uncommon (around 5% prevalence or less), the AOR can closely approximate the RR. However, for more common diseases (for example, with a 40% prevalence of hypertension), the odds ratio tends to overestimate the risk compared to the RR, diverging more as the prevalence increases.

a) The possibility space is completed with the potential outcomes of spinning both spinner A and spinner B.
b) The probability of getting a negative score is 2/9.
c) The probability of scoring more than 3 is also 2/9.
a) **Possibility Space:**
```
Spinner A
2 4 6
Spinner B 3 1 -1 -3
6 4 0 -2
9 7 3 1
```
In the possibility space, each cell represents the outcome of spinning both spinner A and spinner B. The score is obtained by subtracting the number on spinner A from the number on spinner B.
b) **Probability of Getting a Negative Score:**
To calculate the probability of getting a negative score, count the number of occurrences where the result is negative and divide it by the total number of possible outcomes. In this case, there are two instances (-1 and -2) where the score is negative. The total number of outcomes is 9.
Probability of negative score = Number of negative outcomes / Total number of outcomes
Probability of negative score = 2 / 9
c) **Probability of Scoring More Than 3:**
To find the probability of scoring more than 3, count the number of occurrences where the result is greater than 3 and divide it by the total number of possible outcomes. In this case, there are two instances (4 and 7) where the score is more than 3.
Probability of scoring more than 3 = Number of outcomes > 3 / Total number of outcomes
Probability of scoring more than 3 = 2 / 9

cuboid of length 24cm and volume 768cm^3 the width and hight are not equal.give a pair of possible values for their length.
Answer:
Possible values of dimensions are (24,16,2) or (24,8,4)
Step-by-step explanation:
We are given the volume of the Cuboid and length . We are required to find the possible values of width and height from this information.
Let us say that the width is x and height is y
Length = 24
Volume of a cuboid = length * width * height
Volume = 768
768=24*x*y
[tex]xy=\frac{768}{24}\\xy=32\\[/tex]
xy=32
Now the possible factors of 32
32=1*32 ( Which shall not be taken into consideration as length is already given as 24 and width or height can not be more length)
32=2*16
32=4*8
Hence the possible values width are 8, 16 and that of height 4 and 2
Hence the possible values of dimensions are (24,16,2) or (24,8,4)

q: A right angle measures 90°.
r: Four points are always coplanar.
s: A decagon has 12 sides.
r ∧ (q ∨ s)
Select one:
A. Four points are always coplanar, or a right angle measures 90° and a decagon has 12 sides; false.
B. Four points are always coplanar, and a right angle measures 90° or a decagon has 12 sides; true.
C. Four points are always coplanar, or a right angle measures 90° and a decagon has 12 sides; true.
D. Four points are always coplanar, and a right angle measures 90° or a decagon has 12 sides; false.
Answer:
Options b and D
Step-by-step explanation:
It's a question of Boolean's algebra
We will find the truth values of each statement p, q, r, and s first.
p : An isosceles triangle has two congruent sides.
Means truth value is True
q ; A right angle measures 90°
Truth value of this statement will be True
r : Four Points are always coplanar.
Truth value of this statement will be False.
s : A decagon has 12 sides
Truth value of the statement will be False.
Now we come to the options.
a. Four points are always coplanar and a right angle measures 90°.
Here "and" means conjunction and truth value of conjuncion of two statements will be true if only both the statements are true.
r q r ∧ q
T T T
But the truth value is given as false so not the correct option.
b. Four points are always coplanar and a right angle measures 90°.
As we have discussed in option a. truth value of the conjunction is True so this option will be the correct option.
c. Four points are always coplanar or a right angle measures 90°
OR means it's a disjunction and truth value of disjunction is false only when both the statements are False.
r q r ∨ q
T T T
But the truth value is given as False, so this option is not correct.
d. Four points are always coplanar or a right angle measure 90°
As discussed in option c. Truth value will be True. so this option will be the correct option.
Options b and d are the correct options.

(6x-7)+(3x-29)
Answer:
180°
Step-by-step explanation:
(8y+17)°=(6x-7)°
(3x-29)°+(8y+17)°=180°
so,
(3x-29)°+(6x-7)°=180°
To solve the expression (6x-7)+(3x-29), we combine like terms. The 'x' terms (6x + 3x) sum up to 9x and the constants (-7 and -29) sum up to -36. Therefore, the simplified expression is 9x - 36.
Explanation:The student wants to solve the expression (6x-7)+(3x-29). To do this, you should combine like terms, which means you should add together the terms that have the same variable.
Step 1: Add the 'x' terms together. This would give us 6x + 3x which equals 9x.
Step 2: Then add the constants together, in this case -7 and -29, you get -36.
So, the simplified result of the expression (6x-7)+(3x-29) is 9x - 36.

the graph shows vectors a and b the resulting vector for b - a is blank, blank >, and the resulting vector for 2a -b is < blank, blank >.
Answer:
The resulting vector b - a is <-5 , 7>
The resulting vector 2a - b is <8 , -9>
Step-by-step explanation:
* Use the graph to solve the problem
- The vector a is <3 , -2>
- The vector b is <-2 , 5>
* We can add and subtract the vectors
∵ a = <3 , -2>
∵ b = <-2 , 5>
- To find b - a subtract a from b
∴ b - a = <-2 , 5> - <3 , -2> = <(-2 - 3) , (5 - -2)> = <(-5) , (7)>
∴ The resulting vector b - a is <-5 , 7>
* 2a means multiply vector a by 2
∵ a = <3 , -2>
∴ 2a = <(2 × 3) , (2 × -2) = <6 , -4>
* Now lets find the resulting vector 2a - b
- Subtract b from 2a
∵ 2a = <6 , -4>
∵ b = <-2 , 5>
∴ 2a - b = <6 , -4> - <-2 , 5> = <(6 - -2) , (-4 - 5> = <(8) , (-9)> = <8 , -9>
∴ The resulting vector 2a - b is <8 , -9>

a shaded region above a dashed boundary line
a shaded region below a dashed boundary line
Answer: D is correct dotted and shaded below
Step-by-step explanation:
It’s a dotted line because the symbol is < or >
Everything below the line will be shaded because it’s y<, if it were y> then everything would be shaded above
Answer:
A shaded region below a dashed boundary line
Step-by-step explanation:
Conveniently it has been established, that in inequalities graph dashed lines indicate that all the points ∈ line expressed by y< -1/2x+5 part of the inequality are not included. So we represent by shaded regions below dashed lines.
If this inequality was then expressed by y<= -1/2x +5 then a solid line would then represent.
