Find the median
X 20 25 29 33 38 42 43
F 6 20 24 28 15 4 2 1
Answer:
The median for X is "33"
The median for F is "10.5"
Step-by-step explanation:
Answer:
33 and 10.5
Step-by-step explanation:
The median is the middle number in the data set arranged in ascending order.
If there is no exact middle value then it is the average of the 2 numbers either side of the middle.
X 20 25 29 33 38 42 43
↑ middle number
Thus the median = 33
Arrange set F in ascending order.
F 1 2 4 6 15 20 24 28
↑ middle between 6 and 15
Thus the median = [tex]\frac{6+15}{2}[/tex] = [tex]\frac{21}{2}[/tex] = 10.5

Answer:
D. The function has no intercepts.
Step-by-step explanation:
There are vertical and horizontal asymptotes on both the x and y-axis (meaning nothing can touch them), so it is impossible for there to be any intercepts.

1. & 2. In the diagram below, points A, B, and C are collinear. Answer each of the following questions. The figure shown below is not drawn to scale, meaning you cannot determine your answers by using your ruler.
Answer:
a). AB = 8 in
b). AB = 9.75 in
c). AC = 6.5 in
d). BC = 1.5 in
Step-by-step explanation:
a). Since, AB = AC + CB
Length of AC = 5 in. and CB = 3 in.
Therefore, AB = 5 + 3 = 8 in.
b). Given : AC = 6.25 in and CB = 3.5 in
Therefore, AB = AC + CB = 6.25 + 3.5
AB = 9.75 in.
c). Given: AB = 10.2 in. and BC = 3.7 in.
AB = AC + BC
AC = AB - BC
AC = 10.2 - 3.7
AC = 6.5 in
d). Given: AB = 4.75 in and AC = 3.25 in.
BC = AB - AC
BC = 4.75 - 3.25 = 1.5 in.

Answer:
y = 2(x + 3)(x + 1)
Step-by-step explanation:
Use the formula y = a(x-b)(x-c)
b and c are the x-intercepts
The x-intercepts in this function are -3 and -1
y = a(x+3)(x+1)
substitute the point (-2, -1)
-2 = a(-2 + 3)(-2 + 1)
-2 = a(1)(-1)
-2 = -a
a = 2
y = 2(x + 3)(x + 1)

8.) Write an inequality that can be used to represent this situation, where x represents Olivia’s sister’s age. (Short answer)
Olivia is 6 years older than her sister. The sum of their ages is no more than 28 years.
Bonus: What is the oldest age her sister can be?
please show work!! It took me ages to try to solve this!
thank you future answers! :D
Answer:
The oldest age of Olivia’s sister can be 11 years.
Step-by-step explanation:
Given: Olivia’s sister’s age is x years.
To write: inequality that can be used to represent the given situation.
As Olivia is 6 years older than her sister,
Olivia's age [tex]=x+6[/tex]
As the sum of their ages is no more than 28 years,
[tex]x+(x+6)\leq 28\\2x+6\leq 28\\2x\leq 28-6\\2x\leq 22\\x\leq \frac{22}{2}\\ x\leq 11[/tex]
So, the oldest age of Olivia’s sister can be 11 years.

How can you distinguish if the solution is one value, all real numbers, or no solutions?
Answer:
If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.
Step-by-step explanation:
For example:
One value: 7 + x= 10 => x= 3
All real numbers: 0x=0 => x can be all real numbers
No solutions: 7x=6x => no solutions
Based on a mathematical equation, and the content of the question, there are various ways to determine the outcome of the solution, this includes knowing the type of equation and the connection between equation components.
What is a mathematical solution?The mathematical solution is a term that ks used to describe the assignment of values to the unknown variables that make the equality in the equation true.
Generally, the mathematical solution is a value or a collection of values such that, when substituted for the unknowns, the equation becomes equal.
Hence, to determine if an equation has one solution or no solutions, consider the following factors.
Type of equation, such as Linear equations, Quadratic equations, Absolute value equations, Exponential and logarithmic equationRelationship between equation components, such as Operations performed on both sides, Inverse operations, Contradictions, or identities.Hence, in this case, it is concluded that various factors including graphing the equation or using numerical methods can help visualize or approximate the mathematical solution set.

Which is an example of structured observation?
A. A parent visits her son's second-grade classroom to
observe his behavior.
B. A zoo employee observes a new gorilla's interaction
with the other gorillas in the enclosure.
C. A new employee sits beside a veteran employee to see what types of situations occur during a normal work
day.
D. After receiving an anonymous tip, a supervisor
observes his staff to see if any of them are downloading music while they should be working.
The example of structured observation is when a new employee sits beside a veteran employee to see what types of situations occur during a normal work
For better understanding, let's explain what structure observation means
Structured Observation is simply refered to as method or technique often used for data collection. it is said to rely on wide or explicit rules for observing, categorizing, and recording behaviour of all types.There is direct observation of behaviour of which is not often used due to the fact that there is limited access to some social spaces and difficulty in capturing some behaviours. It is made up of smaller sample sizes.From the above we can therefore say that the answer The example of structured observation is when a new employee sits beside a veteran employee to see what types of situations occur during a normal work is correct

What is the value of x?
x= ??
Answer:
X=50
Step-by-step explanation:
Because the top and bottom angles are formed by 2 intersecting lines, we know that the angles are equivalent to each other via the vertical angle theorem. This allows us to set the following equation:
[2(x+10)]=(3x-30)
You would then distribute the 2 on the left side to get
2x+20=3x-30
Then, simply combine like terms.
20+30=3x-2x
Simplify.
50=x
The answer is therefore 50.

Kiera thinks of a number.
She subtracted 4 from it.
Then she multiplied that
answer by 3. She got a final
answer of 24. What was her
starting number?
Answer:
24/3-4
Answer is 12
Step-by-step explanation:
To find the answer, you have to work backwards. You also have to use PEMDAS. Since she multiplied her answer to get 24, you have to work backwards and divide by 3 first. You will get the number 8 after that because 24/3 is 8. Since she also subtracted 4, you have to work backwards and add 4. That gives you an original number of 12.
Answer:
12
Step-by-step explanation:
explanation: if you go backwards you divide 24 by 3 getting 8, then you add 4 to that and then you get 12.

Hurry, I'll mark brainliest!!! Write the sentence as an equation. The product of q and 321 is the same as z
Answer: 321q = z
This is the same as z = 321q
The term "product" means "result of multiplying two or more values"
For example, the product of 2 and 3 is 2*3 = 6
Writing 321q is the same as 321*q, but we often leave out the multiplication sign. You could say q*321, but convention usually has the number come first then the variable second. The 321 is the coefficient.
Solve for n 11(n – 1) + 35 = 3n
Answer:
n=-3
Step-by-step explanation:
Given: 11(n-1)+35=3n
Multiply 11 with the parenthesis. 11n-11+35=3n
Combine like terms. 11n+24=3n
Take 3n away from each side. 8n+24=0
Take 24 away from each side. 8n=-24
Divide each side by 8. n=-3
