Answer:
27
Step-by-step explanation:
Let a represent Amanda's age. Then Jordan's age is 2a+5, and the combined ages are ...
a +(2a+5) = 38
3a = 33
a = 11
So, Jordan's age is ...
2(11) +5 = 27

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.
Jon is 5 years older than Dana. Ella is twice as old as Jon and Zach is twice as old as Dana. The sum of their ages is 93. How old is Jon?
Answer:
Dana's age = 13 years
Zach's age = 26 years
Jon's age= 18 years
Ella's age = 36 years
Step-by-step explanation:
Let
Dana's age = x
Zach's age = 2x
Jon's age= x + 5
Ella's age = 2(x + 5)
Sum of their age = 93
x + 2x + (x + 5) + 2(x + 5) = 93
x + 2x + x + 5 + 2x + 10 = 93
6x + 15 = 93
Subtract 15 from both sides
6x + 15 - 15 = 93 - 15
6x = 78
Divide both sides by 6
x = 78/6
= 13
Therefore,
Dana's age = x = 13 years
Zach's age = 2x
= 2(13)
= 26 years
Jon's age= x + 5
= 13 + 5
= 18 years
Ella's age = 2(x + 5)
= 2(13+5)
= 26+10
= 36 years
Dana's age = 13 years
Zach's age = 26 years
Jon's age= 18 years
Ella's age = 36 years
Sum of their age = 13 + 26 + 18 + 36
= 93 years

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.

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.

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]

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.

A student group at NAU collected information from a local dine in resturant indicating the tip amount left by customers over the course of a two year period. The tip amounts were roughly normally distributed with a mean of $7.84 and a standard deviation of $2.60
Answer:
The desired range will be "($ 2.64, $ 13.04)".
Step-by-step explanation:
The query given seems to be missing. Kindly check find the entire questions attachment.
The given values are:
Mean
= $ 7.84
Standard deviation
= $ 2.60
Those are established by empirical rule whether 95% including its values cheat throughout two standard deviations of such the mean, for something like a roughly normal distribution results.
Thus, the range of values which might absorb 95% of all sums will be:
= [tex](Mean - 2\times Standard \deviation, Mean + 2\times Standard \ deviation)[/tex]
On putting the estimated values, we get
= [tex](7.84 - 2\times 2.60, 7.84+ 2\times 2.60)[/tex]
= [tex](7.84-5.2, 7.84+5.2)[/tex]

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

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
