Answer:
π x³ /12 is the volume of the cone if A cone has a height of x and a diameter of x
Step-by-step explanation:
The base diameter and the height of a cone are both equal to x units
Diameter of cone = x units
Radius = Diameter /2
=> Radius of cone = x/2 units
Height of cone =x units
Volume of cone = (1/3) π r²h
r = radius h = height
=> Volume of cone = (1/3)π (x/2)² * x
= (1/3) π (x²/4) * x
= (1/12) π x³
= π x³ /12 cubic units
here is the histogram of a data distribution. all class widths are 1. which of the following numbers is closest to the mean of this distribution a)3 b)5 c)4 d)9 e)7
The number 5 is closest to the mean of the distribution, option (B) is correct.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
From the histogram:
2, 6, 4, 2, 0, 1, 6, 4, 2, 1
The sum of the above data = 28
= 2×1+6×2+4×3+2×4+0×5+1×6+6×7+4×8+2×9+1×10
= 2+12+12+8+6+42+32+18+10
= 142
Mean = 142/28
= 5.07
Thus, the number 5 is closest to the mean of the distribution option (B) is correct.

y=1/2(0.25)^0-1. +2
y=1/2(0.25)^-1 +2
y=1/2*4+2

A nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes. What is the probability of the complement of the event? Express your answer as a fraction in simplest form.
The probability of the complement of the event is 3/4 if the nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of contains in the bag = 15+10+15 = 40
Total number of nickel = 10
The probability of getting the nickel = 10/40 = 1/4
The complement of the probability:
P' = 1 – 1/4
P' = 3/4
Thus, the probability of the complement of the event is 3/4 if the nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes.

based on a survey of 425 master’s programs in business administration, the u. s. news & world report ranked the indiana university kelley business school as the 20th best business program in the country (america’s best graduate schools, 2009). the ranking was based in part on surveys of business school deans and corporate recruiters. each survey respondent was asked to rate the overall academic quality of the master’s program on a scale from 1 “marginal” to 5 “outstanding.” use the sample of responses shown below to compute the weighted mean score for the business school deans and the corporate recruiters. discuss.quality business school corporate assessment deans recruiters 5 44 31 4 66 34 3 60 43 2 10 12 1 0 0
The deans have a higher weighted mean score for business schools which is 3.8.
What is weighed mean?The weighted arithmetic mean is similar to the conventional arithmetic mean in that certain data points contribute more than others to the final average.
Weighed mean = (weightage x parameter)/no of parameters
The Weighted mean score for deans
= [(5×44)+(4×66)+(3×60)+(2×10)]/(44+66+60+10)
= 684/180
= 3.8
The Mean weigted score of recruiters
= [(5×31)+(4×34)+(3×43)+(2×12)]/(31+34+43+12)
= 444/120
= 3.7
Hence, The deans have a higher weighted mean score for business schools which is 3.8.

Answer:
The 8.39-kg bag
Step-by-step explanation:
19.99 divided by 7.98 = $2.51
20.38 divided by 8.39 = $2.43
2.51 > 2.43
So 8.39-kg bag is the better buy
Answer:
7.98: $2.51/kg8.39: $2.43/kgthe 8.39 kg bag is the better buyStep-by-step explanation:
To find the unit price, divide the price by the number of units. Here, the unit of interest is 1 kg.
__
Unit price of 7.98 kg bag:
$19.99/(7.98 kg) = $2.51 /kg
__
Unit price of 8.39 kg bag:
$20.38/(8.39 kg) = $2.43 /kg
__
The 8.39 kg bag has a lower cost per kilogram, so is considered the better buy.

Ms. Jones baked 12 cookies on Monday. On Tuesday, she baked 15 cookies, on Wednesday, she baked 18 cookies. If Ms. Jones continues baking cookies this way, how many will she bake on Friday?
Answer:
19 or 20
Step-by-step explanation:
well is see
Monday = 12
Tuesday = 12 + 3 = 15
Wednesday = 15 +3 = 18
so the pattern is 3
but now since there is only 14, 13, 19, and 20
we could say she only added 1 or 1 each time
because it said she wanted cookies to stay about 18
1 x 2 = 2
18 + 2 = 20
or
1 + 18

The new floor plan for the interior of a home is below. Marisa wants to cover various parts of the floors with carpet, tile, or wood.
If tile costs $1.29/sq. ft., how much will the tiled portion of the floor plan cost?
A) $1,548.00
B) $1,161.00
C)5387.00
D) $774.00
Answer:
C. $774.00
Step-by-step explanation:
First, you have to find the area of the area that is tile, in this case, it is a trapezoid.
Area of Trapezoid formula:
A= 1/2(b1+b2)h
h= height
b=base
A= 1/2(15+25)30
A= 1/2(40)(30)
A=1/2(1,200)
A= 600
Now, you multiply 600 by the cost of the tile to get how much money it will cost.
600*1.29= $774.00
A box of chocolates contains 18 chocolate squares. 10 of the squares are milk chocolate. 5 are dark chocolate and 3 are white chocolate if christina randomly chooses a chocolate out of the box, what is the probability of her choosing a white chocolate square
Answer:
Either %16.67 or %17 if rounded
Step-by-step explanation:.
An easy way to do this is convert the probability from a fraction into a percent. We can do this by taking the total number of chocolate squares (18) and using this as a denominator. Then take the number of white chocolate squares (3) and using this as our numerator. This give us a fraction of 3/18. Now to turn this into a percent, we need to find what you need to multiply 18 by to get 100. We can do this easily by deviding 100 by 18. This is a long decimal so i'll keep it in fraction form (100/18). Now you just have to multiply 3 by (100/18). This is about 16.67. If the answers are rounded it will be 17%.

Hi guys !
Find the missing angle in the given figure .
All the best *
Answer:
third angle: 50°
Explanation:The interior angles of a triangle sum ups to 180°.
Here given two angles: 95°, 35°, x - Let the missing angle be x
When they sum up, they equal to 180:
x + 35 + 95 = 180
x + 130 = 180
x = 180 - 130
x = 50
Given two angles are 35° and 95°
Let the unknown angle be "x"
We know that sum of angles of a triangle is 180°
Therefore,
[tex]\sf{35°+95° + x = 180°}[/tex]
[tex]\sf{130° + x = 180°}[/tex]
[tex]\sf{x = 180°-130°}[/tex]
[tex]\sf{x = 50°}[/tex]
Hence, the missing angle is 50°.

find the area of a square whose perimeter is 840m
Answer:
Area of square = 44,100 m²Step-by-step explanation:
Given :-
Perimeter of square = 840 cmTo find :-
Area of sqaureSolution :-
The find area of sqaure firstly we need to find the length of each side of the sqaure.
We know that,
Perimeter of rectangle = 4 × side
→ 840 = 4 × side
→ 840/4 = side
→ 210 m = side
Side of square is 210 m→ Area of rectangle = (Side)²
→ Area = (210)²
→ Area = 44,100 m²
Hence, Area of the square is 44,100 m²Hey ! there
Answer:
Area of square is 44100 m² .Step-by-step explanation:
In this question we are provided with a square having perimeter of square 840 m . And we are asked to find the area of square .
For finding area of square we need to find the side of square . So , we are finding the side of square by assuming it as " x " metres and then equating it with given perimeter that is 840 m .
We know that ,
[tex] \qquad \quad \underline{\boxed{\frak{Perimeter_{(Square)} = 4 \times Side }}}[/tex]
SOLUTION : -
✼ Finding Side ,
Substituting value of side as x in formula and equating it with 840 :
[tex] \quad \longmapsto \qquad \: 4 \times x = 840[/tex]
or ,
[tex] \quad \longmapsto \qquad \:4x = 840[/tex]
Dividing with 4 on both sides :
[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{4}x}{ \cancel{4}} = \cancel{ \dfrac{840}{4} }[/tex]
We get ,
[tex] \quad \longmapsto \qquad \: \underline{\boxed{\frak{x= 210 \: m}}}[/tex]
Therefore , SIDE of square is " 210 " metres .
✼ Finding Area ,
We know that ,
[tex] \: \qquad \: \qquad \: \underline{\boxed{\frak{Area_{(Square)} = Side {}^{2} }}}[/tex]
Now , substituting value of side as 210 in formula :
[tex] \quad \dashrightarrow \qquad \: (210) {}^{2} [/tex]
or ,
[tex] \quad \dashrightarrow \qquad \:210 \times 210[/tex]
Multiplying 210 two times , We get :
[tex] \quad \dashrightarrow \qquad \:\blue{\underline{\boxed{\frak{44100 \: m {}^{2} }}}} \quad \bigstar[/tex]
Henceforth , AREA of square having perimeter 840 m is ❝ 44100 square metres ❞
