Noah was asked to find the median of the following numbers.
115, 109, 117, 136, 127, 131
Noah’s work is shown below.
109, 115, 117, 127, 131, 136
StartFraction 117 + 127 Over 2 EndFraction = StartFraction 244 Over 2 EndFraction = 122
What error, if any, did Noah make?
He forgot to put the numbers in order first.
He crossed off the high/low number pairs incorrectly.
He left out a number when putting the numbers in order.
He did not make any error.
Answer:
No error
Step-by-step explanation:
Nothing to explain
Answer:
Noah did not make any errors
Step-by-step explanation:
The median is a list of strictly increasing numbers is simply the middle number. if there's an even number of numbers in the list, then the median is the average of the middle terms.
here, the numbers are 115, 109, 117, 136, 127, 131. when ordered from least to greatest we get 109, 115, 117, 127, 131, 136 which is what Noah got.
since there are 6 numbers (6 is even), the median will be the average of the middle two numbers which are 117 and 127: (117+127)/2=244/2=122
so Noah is was correct.

The sum of the given expression will be equal to -3.
What is an Algebra?Algebra is the study of mathematical symbols and the rules for manipulating them in formulas; it is a common thread that runs through practically all of mathematics.
given expression:
=[tex]\left[\begin{array}{c}2&3\end{array}\right][/tex] + [tex]\left[\begin{array}{c}-5&6\end{array}\right][/tex]
= [tex]\left[\begin{array}{c}2 +(-5)&3+6\end{array}\right][/tex]

Part A: A number is increased by 54. The sum is then divided by 9. The result is 21.
Write an equation to represent the description above. Use n for the number.
Equation:
Part B: Find the value of n. Show your work.
n =
Part C: Choose two numbers and use them to do the following:
Write an equation that shows your first number added to n equal to your second number. Solve your equation for n.
Equation:
Solution:
Answer:
(n +54)/9 = 21; 135= n
Step-by-step explanation:
(n+54)/9 = 21
n+54/9 *9= 21*9
n+54-54 = 189-54
n= 135
the first part is simply recognizing the order its written and the words used.
So to start off with, they use the turn "a number" so we know there's going to be some form of a variable. From there it says "increased by" rather than "multiplied" or "doubled" or something of that nature, so we know its adding 54 rather than multiplying. Then, the next part says that "the sum" which is another key term for addition, "is then divided by 9". So we can assume so far that a variable plus 54 is added together to get a number, which is then going to be taken and divided by 9. The last part says "the result is 21", which simply means that we need to end up with 21.
So once we gather all this information, we can put it together as so: (n +54)/ 9 = 21.
I put parentheses around the n + 54 to make sure that the equation is following the system of equations (PEMDAS).

Judys town voted on a new speed limit. 95% of the 2,000 votes were in favor of the new speed limit. How many voted were in favor
Answer:
1,900 votes were in favor.
Step-by-step explanation:
Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:
2000*95%=1900
According to this, the answer is that 1,900 votes were in favor.

Shanley would like to give $5 gift cards
and $4 teddy bears as party favors.
Shanley has $120 to spend on party
favors. Write an inequality to find
the number of gift cards x and teddy bears
y Shanley could purchase.
Give onc solution to the incquality.
Answer:
$5x + $4y ≤ $120
let x = 10
y = 5
$70 ≤ 120
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater or equal to
≤ means less than or equal to
the total amount Shanley has is $120. She can spend less than this amount or the amount exactly. So, the inequality sign to be used is ≤
$5x + $4y ≤ $120
let x = 10
y = 5
(50) + 20 ≤ 120
$70 ≤ 120
-x - 4y = 10 in function form
Answer:
y=-x-10

The answer would be B.
Step-by-step explanation:
It couldn't be A because it just doesn't make sense because if the dot means a student then what are the numbers on the bottom mean.
It also couldn't be D because nowhere does it say anything about teachers.

Is the function linear, quadratic, or exponential?
f(x)=2−3x2+x
Answer:
No, it is a quadratic function.
Step-by-step explanation:
An exponential function has the variable as the exponent. 3^x would have been an example of an exponential function. In this function, the exponent is not variable, it is 2. Therefore this is a quadratic function, not an exponential one.
Write the exact value of, or estimate, the side length of a square with an area of 100 square units.
95 square units.
36 square units.
30 square units i’ll give brainliest
Answer:
l =10 units, 9.7 units, 5.5 units
Step-by-step explanation:
Area = length x breadth
Area of a square = l^2
100= l^2
√100 =√l^2
l=10 units
95=l^2
√95 = √l^2
l= 9.7 units
30=l^2
√30=√l^2
l= 5.5 units

Write the nth term of the following sequence in terms of the first term of the sequence.
2, -4, 8, -16, . . .
Answer:
[tex]\bold{a_n=2\cdot(-2)^{n-1}}\\\\or\\\\\bold{a_n=(-1)^{n-1}\cdot2^{n}}[/tex]Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence: [tex]a_n=a_1\cdot r^{n-1}[/tex]
Therefore:
[tex]a_n=2\cdot(-2)^{n-1}\\\\a_n=2\cdot(-1\cdot2)^{n-1}=2\cdot(-1)^{n-1}\cdot2^{n-1}=(-1)^{n-1}\cdot2^{n-1+1}\\\\a_n=(-1)^{n-1}\cdot2^{n}[/tex]
Answer:
2(-2)^n-1

A drawing of a triangle. The base equals 15 centimeters and height equals 8 centimeters.
Answer:
17
Step-by-step explanation:
If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)
how do u do 2 over 3 =A over 60 PLZ NO LINKS THANKS
Hey there!
2/3 = a/30
First: you have to CROSS MULTIPLY the given numbers
2(30) = 3(a)
2(30) = 60
3(a) = 3a
New EQUATION: 3a = 60
Second: DIVIDE 3 to BOTH SIDES
3a/3 = 60/3
CANCEL out: 3/3 because that gives you 1
KEEP: 60/3 because that helps you solve for your a-value
60/3 = a
60/3 = 20
Therefore, your answer is: a = 20
Good luck on your assignment and enjoy your day!
