Answer:
Step-by-step explanation:
first arrange the data from ascending to descending order.
11 , 12 , 15 , 17 , 19 , 20 , 21 , 22
Median(Q2)=(N+1)/2
=8+1/2
=9/2
=4.5 th term
=(4 th term + 5 th term)/2
=(17+19)/2
=36/2
=18
therefore the median of the set of data is 18.

Evaluate 32 + (7 − 2) ⋅ 4 − 6 over 3 . (1 point)
Answer:
50
Step-by-step explanation:
Given:
32 + (7 − 2) ⋅ 4 − 6/3
Using the acronym PEMDAS
P = parenthesis
E = Exponential
M = Multiplication
D = Division
A = Addition
S = Subtraction
32 + (7 − 2) ⋅ 4 − 6/3
= 32 + (5) • 4 - 6/3
= 32 + 20 - 6/3
= 32 + 20 - 2
= 52 - 2
= 50
Therefore,
32 + (7 − 2) ⋅ 4 − 6/3 = 50

What is true about -9.94 and -9.8 when
plotted on a number line?
Answer: A number line is defined as the pictorial representation of numbers such as fractions, integers, and whole numbers laid out evenly on a straight horizontal line. Positive numbers are plotted to the right of the origin while negative numbers are plotted to the left of the origin.
Step-by-step explanation:
When solving the equation 6x - 8 = 12, the first step is to move the
constant, 8, to the right side by adding 8 to both sides. What is the
equation after step one?*
6x - 8 = 12 + 8
14x - 8 = 20
6x = 12 + 8
6x = 20
Answer:
6x= 12+8

Answer:
x < 3/14
Step-by-step explanation:
-14x > -3
divide each side by -14
however, whenever multiplying or dividing an inequality by a negative value then you must reverse the inequality symbol
x < 3/14
Answer:
divide by -14:
[tex]x<3/14[/tex]
when you divide by a negative the sign flips

What value do you square to get 9?
Answer:
3 or -3
Step-by-step explanation:
What number multiplied by itself will give you 9
1*1 =1
2*2 =4
3*3 =9
Also note that negative times negative will be positive so
-1*-1=1
That means -3*-3 = 9
Answer:
3^2 0r (-3)^2
Step-by-step explanation:
let the number be x
x^2=9
x=[tex]\sqrt{9[/tex]
x=[tex]\sqrt{3*3[/tex]
x=3
there fore x=plus or minus 3.since it is a sqauring a number if u square (-3)^2 along will the number sign also gets multiplied and (-*-)=+ so u we get positive number.
therefore if u square 3 then u will get 9
A rhombus has the same properties as a square. True False
Answer: True
Step-by-step explanation: am i wrong
Answer:
false
Step-by-step explanation:
in a rhombus all interior angles are not equal even though they have equal sides.while in a square all sides are equal including interior angles. so no a rhombus does not have the same properties

Money in a bank triples every 9 years. If $100 is deposited today, what will it's value be after 36 years?
Answer:
[tex]\$8,100[/tex]
Step-by-step explanation:
We can denote this increase with the function [tex]y=3^x\cdot 100[/tex], where [tex]y[/tex] is value after [tex]\frac{x}{9}[/tex] years.
Substituting [tex]x=36[/tex], we get:
[tex]3^4\cdot 100=\boxed{\$8,100}[/tex]
Answer:
8,100
Step-by-step explanation:
The first 9 years would be 300, then 18 years would be 900, and 27 years it would be 2,700, and finally after 36 years it would be 8,100.

1 / 5^4
Step-by-step explanation:
5^3 / 5^7
We know a^b / a^c = a^(b-c)

5^-4
If you are not allowed to have negative exponents
We know a^-b = 1/a^b
1 / 5^4
I made a mistake while solving the inequality below. What mistake did I make? Explain what I should’ve done instead.

Find the average rate of change of a function that contains the points (-2,3) and (2,5)
Answer: [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Rate of change are typically found using [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex].
[tex](x_{1}, y_{1}) = (-2, 3)\\(x_{2}, y_{2}) = (2, 5)\\\\\frac{5-3}{2-(-2)} =\frac{2}{2+2} =\frac{2}{4} =\frac{1}{2}[/tex]
Therefore, the rate of change(aka slope) is [tex]\frac{1}{2}[/tex].

Answer:
a ≈ 14.39
Step-by-step explanation:
7² + a² = 16²
49 + a² = 256
49 - 49 + a² = 256 - 49
a² = 207
√a² = √207
a = 14.3874945699
a ≈ 14.39

1. Provide an example of a variable term.
2. Provide an example of a constant term.
3. When looking at an expression and/or equation, how can we tell that we need to distribute?
4. When solving an equation, if you get the solution, x=0, how many solutions to the equation are there?
(One solution, no solution, or infinite solutions)
5. When solving an equation, if you get 5 = 11, what does this mean? (One solution, no solution, or infinite
solutions)
6. When solving an equation, if you get 5 = 5, what does this mean? (One solution, no solution, or infinite
solutions)
Answer:
Step-by-step explanation:
1) a variable term contains a variable. If x is a variable
5x is an example of a variable therm
2) a constant therm is not a variable
3 is an example
3) for example when a number multiply a sum or a difference between a constant and a variable
Example:
2(x-3) = 5(x+4)
4) one solution: only if x is equal to 0 the equation is true
5) no solution: the equation can’t be true for ever value of the variable
6) infinite solutions: the equation is ever true for every value of the variable
