Answer:
40
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact value in the middle then it is the average of the values either side of the middle.
The data is arranged in ascending order within the dot plot
There are 10 values in the data set
Thus the median is between the fifth and sixth values.
Counting from the left (35)
The fifth value = 39 and the sixth value = 41, thus
median = [tex]\frac{39+41}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40
Answer:
Step-by-step explanation:
Data:
35 , 38, 38 , 39 , 39, 41, 42 , 43, 43, 44
Total number of data = 10
Number of data is even. so, median is the average of (n/2)th term & ([tex]\frac{n}{2}+1[/tex] ) middle term,
Median = average of 5th and 6th term
= (39 + 41)/2 = 80/2 = 40

An architect maps two buildings, which are located on a piece of land, onto a coordinate plane. He wants to build a wall at the diagonal AC to divide the piece of land into two parts. What will be the length of the wall? A. 65–√ units B. 6 units C. 237−−√ units D. 2 units
Answers
Answer:
[tex] 6\sqrt{5} units [/tex]
Step-by-step Explanation:
The length of the wall = diagonal AC = distance between point A (-6, -2) and point C (6, 4).
Distance formula between two points on a graph (d) = [tex] \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Where,
[tex] A(-6, -2) = (x_1, y_1) [/tex]
[tex] C(6, 4) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(6 - (-6))^2 + (4 -(-2))^2} [/tex]
[tex] d = \sqrt{(6 + 6)^2 + (4 + 2)^2} [/tex]
[tex] d = \sqrt{(12)^2 + (6)^2} [/tex]
[tex] d = \sqrt{144 + 36} [/tex]
[tex] d = \sqrt{180} [/tex]
[tex] d = \sqrt{36*5} [/tex]
[tex] d = 6\sqrt{5} [/tex]
The length of the wall = [tex] 6\sqrt{5} units [/tex]

Answers
Answer: A) 67[tex]\frac{11}{117}[/tex] (or) 67.09
B) No. of people neither children nor women
= 468-(314+75)
= 79
= [tex]\frac{79}{468}[/tex]*100
= 16[tex]\frac{103}{117}[/tex] (or) 16.88
I hope it helps. Have a great day :)
Answer:
a) = 67.10 % or 67.09%
b) = 84.10% or 83.97%
Step-by-step explanation:
a = (314/468)*100 = 67.094017094 %
b = (393/468)*100 = 83.9743589744 % (edited 393)
To find b we have to can use simple subtraction to find Men = m = ?
If Women = w = 314 and Children = c = 75
Eliminate the (w = 314) with (c=75) from total to find (m=?)
w+c+m= 468
c+m = 468-w = 468-314 = 154
m = 154-c = 154-75 = 79
m = 79
b) Total sum that were not children = w+m = 314 + 79 = 393
or = 468-314 = 154
then 154 - 79 = 75
with = 468-75 = 393
then find percentage;
(393/468) * 100 = 83.9743589744
Find the distance between the points X and Y shown. Question 5 options: A. 29−−√ B. 21−−√ C. 21 D. 5–√
Answers
Answer:
A
Step-by-step explanation:
From the graph we can notice that the coordinates of the poinrs x and y are:
● x(-2,0)
● y(3,-2)
There are many methods to find the distance between x and y. We will use the distance formula.
Let d be the distance between x and y.
● d = √[(-2-3)^2 + (0-(-2))^2]
● d = √[(-5)^2 + 2^2]
● d = √(25+ 4)
● d = √(29)
The other method was using the pythagorian theorem. d is the hypotenus.

The exponent 3 is a positive number.
The base - 2 is an even number.
Answers
Answer:
just did this on a test and it was
The exponent 3 is an odd number.
Step-by-step explanation:
Hince the statements which justify it:
The base -2 is a negative number.
The exponent 3 is an odd number.
Julie gets a negative number for her final answer when solving the expression (-2)³ = -2 x -2 x -2
Because the base, -2, is a negative number.
When an odd number of negative numbers are multiplied together, the result is always negative.
In this case, there are three negative numbers (-2 x -2 x -2),
Which is an odd number, resulting in a negative answer.
However, since the base is negative, the result will always be negative for any odd exponent.
Therefore, the negativity of the base and the odd value of the exponent together lead to a negative final answer.

a grandfather purchased a brand new car in 1958 for $2500.the car depreciated $325 a year. what would the car be worth 4 years after it was bought?
Answers
Answer:
$1200
Step-by-step explanation:
Since the value of the car depreciates $325 a year.
After 4 years it would be 1300, becuase $325 × 4 = $1300.
So, $2500 - $1300 = $1200
The car worth started at $2,500
Four years would be $325 • 4
It’ll give you the answer of $1,300
You now need to subtract the $1,300 from the $2,500 and you’ll be left with $1,200

Complete the equation of the line through (3,-1) and (4,7). Use exact numbers. What does "y" equal?
Answers
Answer:
lets start with finding the slope
m=7-(-1)/4-3
m=8
now we can choose either of the 2 points given and the slope and plug that into the point slope form
y-7=8(x-4)
y-7=8x-32
y=8x-25
and that is your equation
Answer:
y = 8x - 25
Step-by-step explanation:
The equation of a line is y = mx + b
To find the slope use y2-y1/x2-x1
When you plug it in it will be 7 + 1/4 - 3 (8)
Now it is y = 8x + b
Lastly you need to plug in a coordinate to the equation to find b
7 = 8(4) + b (-25)

l is the length
w is the width
From the question
Area = 6052 m²
width = 68 m
To find the length substitute the values into the above formula
6052 = 68l
Divide both sides by 68
