PLEASE HELP!! The mean absolute deviation for each pizzeria is approximately 10. Approximately how many times the mean absolute deviation is the difference between the means of the data sets?
The required mean absolute deviation is 2.1 times the difference between the means of the data sets.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
To find the means of the two data sets, we need to convert the double stem-and-leaf plots into regular frequency distributions.
To calculate the mean of this data set, we can use the formula:
Mean of Giavano's = (sum of values) / (number of values)
Mean = [31+32+33+36+42+44+46+52+63+68+]/10
Mean= 44.7
Mean of brick oven = (sum of values) / (number of values)
Mean = 38+57+58*2+66+69+74+77+78+79 / 10 = 65.5
Difference of the mean = 65.5-44.7
MAD = 10
According to the question, a ratio of the difference of mean to MAD,
= 65.5 - 44.7 / 10 = 2.1
Thus, the required mean absolute deviation is 2.1 times the difference between the means of the data sets.

Write v = 2x2 + 12x +1 in vertex form.
A. y = (x+3)2 - 17
B. y = (x+4)
C. y=2(x+3)2 – 17
D. y = 2(x + 2)2 + 12
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
y = 2x² + 12x + 1
To express in vertex form use the method of completing the square.
The coefficient of the x² term must be 1 , thus factor out 2 from 2x² + 12x
y = 2(x² + 6x) + 1
add/ subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9) + 1
= 2(x + 3)² - 18 + 1

Ratio means division
So we can rewrite as
5x/8=7/2
Using cross multiply
5x×2=7×8

10x=56
X=56/10
X=5.6
The value of X= 5.6
Answer:
x = 5.6
Step-by-step explanation:
Expressing the ratio in fractional form, that is
[tex]\frac{5x}{8}[/tex] = [tex]\frac{7}{2}[/tex] ( cross- multiply )
10x = 56 ( divide both sides by 10 )

Gandalf was able to save the dwarves from the trolls in The Hobbit because he cleverly confuses the trolls until dawn.
From the story, it should be noted that the dwarves will have been killed by the trolls if not for the help of Gandalf.This wasn't because he magically casts a sleeping spell on them but rather because he cleverly confuses the trolls until dawn.

How many ways can a committee of 4 people be chosen from a group of 8 people if the members are selected in no particular order?
Answer:
70
Step-by-step explanation:
There are 8 choices for the first member, 7 for the second, 6 for the third, and 5 choices for the fourth member (because once you pick someone as a member, they cannot be picked again)
So you have:
8*7*6*5 = 1680
However, we realize that in this particular problem, order DOES NOT matter. (for example, ABCD is the same as DCBA.)
So we divide 1680 by 4! (4*3*2*1) to end up with 70.
You do this because because there are 4! ways to arrange 4 people in a line, and since order doesn't matter, only one of those arrangements counts.

A cylinder has a base radius of 6 inches and a height of 14 inches. What is its volume
in cubic inches, to the nearest tenths place?
Final answer:
The volume of the cylinder is 1580.64 cubic inches.
Explanation:
To find the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius of the base, and h is the height.
In this case, the radius, r, is 6 inches and the height, h, is 14 inches.
So, the volume is calculated as follows:
V = π(6²)(14) = 3.14(36)(14) = 1580.64 cubic inches.

2x-3y=8
Answer:
x=-2/7,y=8/7
Step-by-step explanation:
Simultaneous equation
y=3x+2....(1)
2x-3y=8...(2)
Substitute (1) into (2)
2x-3(3x+2)=8
2x-9x-6=8

-7x=2
Divide both sides by-7
X=-2/7
Substitute the value for x into (1)
y=3(-2/7)+2
y=-6/7+2
Lcm be 7
y=-6+14/7
y=8/7
Therefore x=-2/7,y=8/7

D. $9.96
Answer:
d. 9.96
Step-by-step explanation:
Trust me, I kept googling this for almost an hour.
The Average of the Dinner is 20.66.
What is Average?In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.
The data for dinner is:
18.8, 22.13, 20.79, 24.82, 16.74
The Average of the Dinner is
= ( sum of all data for dinner)/ Total Number of Dinner
As, sum of all data for dinner = (18.8 + 22.13 + 20.79 + 24.82 + 16.74)
=103.28
and, Total Number of Dinner = 5
Now put the values we get
= (18.8 + 22.13 + 20.79 + 24.82 + 16.74) / 5
= 103.28/ 5
= 20.656
= 20.66
Thus, the average of the dinner is 20.66

I need help with this question please I’ll mark as brainliest
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 14), thus
y = a(x - 8)² - 14
To find a substitute (5, 13) into the equation
13 = a(5 - 8)² - 14
13 = a(- 3)² - 14
13 = 9a - 14 ( add 14 to both sides )
27 = 9a ( divide both sides by 9 )
a = 3
Thus
y = 3(x - 8)² - 14 → C
The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?
Answer:
104
Step-by-step explanation:
First, put the word equation into a numerical equation.
-4+5x=7x-212 This is our equation
-4=2x-212 I subtracted 5x from both sides
208=2x I added 212 to both sides
104=x I divided both sides by 2
To solve the problem, we can set up an equation and solve for the variable 'x'. The number is x = -25.
Explanation:To solve this problem, we can translate the given information into an equation. Let's assume the number is 'x'. The sum of -4 and 5 times 'x' is -4 + 5x. The equation becomes 3(-4 + 5x) = 7x - 212. We can simplify this equation and solve for 'x' to find the number.
First, distribute the 3 to -4 and 5x, which gives us -12 + 15x = 7x - 212. Then, combine like terms by subtracting 7x from both sides, which gives us -12 + 8x = -212. Next, add 12 to both sides to isolate the variable, resulting in 8x = -200. Finally, divide both sides by 8 to solve for 'x'. The number is x = -25.

Step-by-step explanation:
( 0.006) 6 is the first significant number.
The number next to it is seven. (0.0067) in which 7 is greater than 5.
therefore, add 1 .
the final answer is 0.007
0.006772 rounded to 1 significant figure is 0.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, 0.006772 and we'll round this to 1 significant figure means only one digit it will have after the decimal place.
So, 0.006772
= 0.006770
= 0.00677
= 0.00680
