What is the mean of the data set?
11, 14, 15, 16, 16, 18, 20, 20, 22, 22
Answer:
The answer is 17.4.
Step-by-step explanation:
Mean is the average of all the numbers. To do this, you have to add up all the numbers then divide by how many numbers there are.
First, let's add up all the numbers.
11+14+15+16+16+18+20+20+22+22 = 174!
Next, let's divide the numbers by how many numbers there are. There are 10 numbers in total.
174÷10 = 17.4
Hope this helps! :3
Answer:
17.4
Step-by-step explanation:
To find the mean of a data set, add all numbers. Then, divide the sum by how many numbers are present.
11 + 14 + 15 + 16 + 16 + 18 + 20 + 20 + 22 + 22 = 174
There are 10 numbers, so divide 174 by 10.
174 / 10 = 17.4
Therefore, 17.4 is the mean of the data set.

76 cm a 52 cm Find the area of the regular pentagon (the answer has one digit after the decimal point)
Answer:
98.8 cm²
Step-by-step explanation:
Hi there!
[tex]A=\frac{1}{2} Pa[/tex] where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)
1) Find the perimeter
[tex]P=5l[/tex] where l is the side length
Plug in the side length 7.6 cm
[tex]P=5(7.6)\\P=38[/tex]
Therefore, the perimeter of the pentagon is 38 cm.
2) Find the area
[tex]A=\frac{1}{2} Pa[/tex]
Plug in the perimeter (38) and the apothem (5.2)
[tex]A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (197.6)\\A=98.8[/tex]
Therefore, the area of the pentagon is 98.8 cm².

Answer:
D. 140
Step-by-step explanation:
In the equation, [tex]ax^2+bx+c=0,[/tex] the discriminant can be found with [tex]b^2-4ac[/tex].
In this equation,
the discriminant would be: [tex](-10)^2-4(2)(-5)=100+40=140[/tex]
Answer:
D. 140
Step-by-step explanation:
D = b² - 4ac
So, let's identify our values.
a = 2
b = -10
c = -5
Now, we can plug in our values.
D = -10² - 4(2)(-5)
D = 100 + 40
D = 140
El 15% de las ventas de un comercio ha sido de productos que valían 100€ o más. Si se han realizado 595 ventas de productos que valían menos de 100€, ¿que numero de ventas se han realizado en total?
Answer:
700 total sales
Step-by-step explanation:
The computation is shown below:
After 15% discount i.e.
= 100 - 15
= 85%
Now
85% = 595 sales of less than € 100
So,
15% = x sales of € 100 or more than € 100
After this
(595 × 15) ÷ 85 = 105 sales of € 100 or more than € 100
The number of total sales is
= 595 + 105
= 700 total sales

one box has 16 apples. another box has 24 lemons. each apple weighs twice as much as each lemon. if a is the weight of the box of apples and b is the weight of the box of lemons, what is a/b?
Answer:
32/24
Step-by-step explanation:
16 times 2 is 32
The value of a/b is 4/3.
What is unitary method?The unitary method is used to find the value of a single unit from a given multiple.
One box has 16 apples.
One box has 24 lemons.
If 'a' is the weight of box of apples and 'b' is the weight of box of lemons.
As each apples weigh 2 times the lemon
Weight of box of apples= 16*2*b=32b
Weight of lemon box = 24b
So, a/b
=32b/24b
=32/24
=4/3.
Hence, value of a/b is 4/3.

Given klmn is a trapezoid, kl = mn, m<1 = m<2, lm/kn = 8/9, pklmn = 132. Find: the length of the legs
Answer:
The length of legs lm, mn, and lk is 32 while that of kn is 36.
Step-by-step explanation:
The diagram is attached in the answer.
As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk
This leads the two set of legs such as
[tex]\dfrac{lm}{kn}=\dfrac{8}{9}[/tex]
Or this could be written as
[tex]lm=8x\\kn=9x[/tex]
Now the remaining two sides are given as
[tex]lk=lm[/tex] as this form an isosceles triangle so
[tex]lk=8x[/tex]
Similarly
[tex]mn=lm\\[/tex]
Or
[tex]mn=8x[/tex]
Now the perimeter is given as
[tex]\text{perimeter}=lm+mn+kn+lk\\[/tex]
Here perimeter is given as 132 so this gives:
[tex]\text{perimeter}=lm+mn+kn+lk\\132=8x+8x+8x+9x\\132=33x\\x=\dfrac{132}{33}\\x=4[/tex]
So the four legs are of length as given below:
[tex]lm=8x=8\times 4=32\\mn=8x=8\times 4=32\\lk=8x=8\times 4=32\\kn=9x=9\times4=36[/tex]
So the length of legs lm, mn, and lk is 32 while that of kn is 36.
Levi and his family belong to a family share plan for their cell phones. The pan includes unlimited minutes, text, and
Internet access for a monthly charge of $250.00 plus $10 for each line. Their plan may include as few as 2 lines and as
many as 12 lines. Complete the table to determine the cost for each plan member. Write a function that can be used
to determine the cost per month, y, for each plan member, X.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of calculations of bills.
The bill calculation goes as equation,
y = $250 + n*($10)
here, n = number of lines,
1.) For n = 2 , Y = cost = 250 + 20 = $270
2.) for n = 4 , Y = $290
3.) for n = 6 , Y = $310
4.) for n = x, Y = $250 + x*($10)
for lastly 12 members we get as,
Y = 250 + (12)*(10) = 250+120 = $370

Find the approximate radius of a circle with a circumference of 34.48 inches. Use 3.14 for pie. Round to the nearest hundredth. Please provide steps.
Answer:
around 5.5 inches
Step-by-step explanation:
34.48 = 2rπ
34.48/π = 2r = around 11
r = 11/2
The radius of the circle is equal to 5.49 inches.
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
here, we have,
Given here:
Circumference as 34.48 inches and π=3.14
Now circumference of the circle is given by
2πr=34.48
r=34.48/2×3.14
r=5.49 inches
Hence, The radius of the circle is equal to 5.49 inches.

Answer: 65in
Step-by-step explanation:
Break the trapezoid into a rectangle (8in by 10in) and the leftovers are 2 triangles. Find the area for the triangles. Because the top of the trapezoid is 10in and the bottom is 15in, then we know that 15-10 = 5 and that the triangles are 2.5in by 8in. Because the triangles are the same congruent, then just multiply 8 by 2.5 to get 20.
Find the middle part now, which is 8 times 10 to get 80. Then 80 + 20 = the area of the trapezoid.
Lastly, subtract the non shaded region (7x5=35) and then 100-35 = 65
