How to calculate the median of a large data set.
Answer:
The first is organize your data set and after that determinate if the length (the total data) is odd or even dependent of that find the middle value. This is the traditional algorithm for find the median of whatever data set.
Step-by-step explanation:
Organize the data set (ascending or descending order)Determine if the total number of data is odd or evenif is odd use the next formula for find the middle value [tex]X[\frac{n}{2} ][/tex] where [tex]X[/tex] is the data set and [tex]n[/tex] the number of data.if is even use the next formula for find the middle value [tex]\frac{X[\frac{n-1}{2}] + X[\frac{n+1}{2}] }{2}[/tex] in this case you take both middle values and get it's mean.Зx — 6 = 3х – ?

Ram's income is 35% more than that of Anil's income. By what percent is Anils incomes less than Ram's income? Step by step answer pls i rly need it
Answer:
100%-35%=75%
so ex-
if ram has an in income is 500
than anil is 35%lower than his so,anil has an income of 350 which is 35%less tan 500.
Answer:
25.9%
Step-by-step explanation:
anil = 100%
ram = 135%
fraction Anils income is of Ram's income
anil/ram = 100/135
a/r = 0.7407407407
74.1%
percent Anils income is less than Ram's income?
100% - 74.1% = 25.9%
4. Elie took $200 to spend during summer vacation. She spent $32 a day for 5 days. Then she bought gelato for her and three friends for $6 each. How much did she have left at the end of the trip?
Answer:
$16
Step-by-step explanation:
32×5=160
6×4=24
160+24=184
200-184=16
Elie was left with $16 at the end of the trip
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Elie who took $200 to spend during summer vacation. She spent $32 a day for 5 days. Then she bought gelato for her and three friends for $6 each.
Assume that she is left with $[x]. Then, we can write the equation as -
x = 200 - {(32 x 5) + (6 x 4)}
x = 200 - {160 + 24}
x = 200 - 184
x = 16
Therefore, Elie was left with $16 at the end of the trip.

A plant is already 41 centimeters tall, and it will grow one centimeter every month. The plant's height, h (in centimeters), after m months is given by the following function.
h(m)=41+m
What is the plant's height after 28 months?
Answer:
69
Step-by-step explanation:
Answer:
Answer
Step-by-step explanation:
H (28) = 41 + 28
H (28) = 69
Each month is +1 cm, which means 41 + 28 = 69 cm is the plant height in 28 months

Five whole numbers are written in order.
4 6 х у
10
The mean and median of the five numbers are the same.
Work out the values of x and y.
Answer:
x = 7, y = 8Step-by-step explanation:
Given numbers in order:
4, 6, x, y, 10The mean is same as median.
The median is x as middle number. Since x is a whole number, the mean is also a whole number.
x and y can be selected from 7, 8 or 9 (numbers between 6 and 10).
The mean is:
(4 + 6 + x + y + 10)/5 =(20 + x + y)/5 = 4 + (x + y)/5It should be a whole number, so (x + y) should be divisible by 5.
The option is (7 + 8) = 15, and 9 is excluded.
Let's verify:
Median = x = 7Mean = 4 + (7 + 8)/5 = 4 + 3 = 7Mean:-
[tex]\\ \sf\longmapsto \dfrac{4+6+x+y+10}{5}[/tex]
[tex]\\ \sf\longmapsto \dfrac{x+y+20}{5}[/tex]
Median:-
n=5M(D)=n+1/2=5+1/2=3rd term[tex]\\ \sf\longmapsto M(D)=x[/tex]
Compare
[tex]\\ \sf\longmapsto \dfrac{x+y+20}{5}=x[/tex]
[tex]\\ \sf\longmapsto x+y+20=5x[/tex]
[tex]\\ \sf\longmapsto 4x=y+20[/tex]
[tex]\\ \sf\longmapsto x=y/4+5[/tex]
[tex]\\ \sf\longmapsto x[/tex]
Take pair of (7,8)
[tex]\\ \sf\longmapsto 7=8/4+5\implies 7=2+5[/tex]

x=7y=8Molly drew a map of her town. She graphed the point L(−1.75, −3) for the library. The ice cream shop is located at L′, a reflection of L across the x-axis. The fire station is located at L′′, a reflection of L′ across the y-axis. Identify the ordered pair that describes the location of the fire station. Express your answer using decimal notation.
(__,__)
Answer:
(1.75, 3)
Step-by-step explanation:
Let's find L' first: We are reflecting L over the x axis, it means it stays on the same vertical (x=-1.75) and it's y changes sign, going to (-1,75,3).
This new point gets reflected again, over the y-axis. The horizontal coordinate (y=3) remains the same, and the x coordinate changes sign, going to it's final destination (1,75, 3)
The measure of side c is 135 inches and

Answer:
The length of side b is 80.
help need it done for tomorrow
Step-by-step explanation:
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
with the sides being opposite to the angles.
so,
14/sin(80) = x/sin(60)
x = 14×sin(60)/sin(80) ≈ 12.3cm
7.4x10^7 in standard form
Answer: 740000000
Step-by-step explanation:
Answer:
0.000074
7.4×10−5
To write in standard notation, move the decimal point on
7.4
over as many times as the power of ten given.
Move to the left if the given power has a negative exponent
Move to the right if the given power has a positive exponent
Therefore:
7.4×10−5=0.000074

What are the coefficient terms and Constants of 10x + 5 + 3x + 1
Answer:
The Coefficients in this expression are 10 and 3, while the constants are 5 and 1.
Step-by-step explanation:
Coefficients = The number that is in front of the variable.
Constant = Any number without a variable.
(Variables are the letters that you may find in an equation or function.)
Hope this helps you :)
Answer:
The coefficient are 10 and 3
The constants are 5 and 1
Step-by-step explanation:
A coefficient is the number in front of any known term.
A constant is a number by itself.
So the coefficient are 10 and 3
The constants are 5 and 1
Ticket sales for for Matilda were 1,120 the first day. The next day, they sold 85 more tickets and made a total income of 2,310. What was the cost per ticket? The cost was dollars per ticket
