Which group has the largest mean absolute deviation? A) Group 1 B) Group 2 C) Group 3 D) Group 4
Answer: B) Group 2
Step-by-step explanation:
Given the data:
Group 1 : 18 25 56 42 29 38 54 47 35 30
Group 2 : 23,19,50,49,67,34,30,59,40,33
Group 3 : 19,22,24,40,45,29,33,29,39,59
Group 4 : 21,23,25,40,35,19,70,40,22,23
The mean absolute deviation (MAD) :
Σ(x - m) / n
Where :
m = mean ; n = number of observations
Using calculator to save computation time :
GROUP 1:
m = 37.4 ; n = 10
Mean Absolute deviation = 10
GROUP 2:
m = 40.4 ; n = 10
Mean Absolute deviation = 12.68
GROUP 3:
m = 33.9 ; n = 10
Mean Absolute deviation = 9.48
GROUP 4:
m = 31. 8; n = 10
Mean Absolute deviation = 11.56
9.48 < 10 < 11.56 < 12.68
Group 3 < group 1 < group 4 < group 2
Group 2 has the highest mean absolute deviation with a value of 12.68
Answer:
group 4

Answer: If the air-plane travels 1020 km in one hour, then it will cover 4250 km in 25/6 hours.
The formula which relates distance, speed, and time is given by d = rt, where d is the distance traveled, r is the rate of travel or the speed, and t is the time traveled. To find out the distance an aircraft will travel in t = 25/6 hours, we must first find out the speed r of the aircraft in kilometers per hour (km/hr) as shown:
d = rt
1,020 km = r(1 hr)
(1,020 km)/(1 hr) = [r(1 hr.)]/(1 hr)
1,020 km/hr = r(1 hr./1 hr)
1,020 km/hr = r(1)
r = 1,020 km/hr
Now, calculating the distance the aircraft will travel in t = 25/6 hours, we have:
d = rt
= (1,020 km/hr)(25/6 hr)
= (1,020)(25/6) km
= (1,020/6)(25) km
= (170)(25) km
= 4,250 km
Answer:
4250 km

Step-by-step explanation:
A pound of chocolate cost six dollars . Donna buys P pound. Write an equation to represent the total cost c that Donna pays 
Answer:
c = 6P
Step-by-step explanation:
equation format: c = mP
c = the total cost Donna pays
m = the cost per pound of chocolate(6)
P = the amount of pounds Donna buys
Since we know the cost per pound is $6, we can input it into the equation format:
c = 6P
Now we have an equation that represents the total cost (c) that Donna pays for P pounds.
Let C = total cost that Donna pays.
Donna buys P pound at $6 per pound tells me to multiply.
C = 6P.

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 4640 seats. The students filled 85% of the seats in the theater. How many 6th graders went on the trip?
Answer
3944
explaination:
multiply 4640 by 85%, you get 394400. next add n with one hundred. now divide 394400 by 100 and you get 3944. enjoy :)

The Playground Center purchases swing sets for $385.99. It sells the swing sets for $598.99. What is the percent of markup? Round to the nearest percent.
Answer:
55%
Step-by-step explanation:
$598.99–$385.99
=$213
$213/$385.99 × 100%
=55%
The profit percent is 55.1%.
What is profit Percent?The profit formula aids in determining the gain in any financial transaction as well as the profit made by selling a specific product, which is typically done in a business. When the selling price exceeds the cost price, a profit can be determined. So, the equation to calculate the profit is:
Profit = Selling Price (S.P.) - Cost Price (C.P.)
and, profit percent = (Profit/Cost Price) × 100.
Given:
Playground Center purchases swing sets for $385.99.
Selling price of swing sets = $598.99.
Profit = $598.99–$385.99
Profit = $213
and, profit percent
=profit / CP x 100
= $213/$385.99 × 100%
=0.551 x 100
= 55.1%
hence, the profit percent is 55.1%.

Given the function f(x) = 2x − 1 and the linear function g(x), which function has a greater value when x = 3?
graph of line g of x equals 4 times x minus 5
Answer:
The function g(x) has a greater value when x = 3. The function g(x) will be 7 when x = 3 while the function f(x) is will be 5
Step-by-step explanation:
For the function f(x), when x = 3, you get the equation f(x) = 2(3) - 1. Two times three equals six, so the equation can be simplified to f(x) = 6 - 1. Six minus one equals five, so f(x) = 5 when x = 3.
For the function g(x), when x = 3, you get the equation g(x) = 4(3) - 5. Four times three equals 12, so the equation is now g(x) = 12 - 5. 12 minus five equals seven, so g(x) = 7 when x = 3.
Hope this helps :)

Aparabola has the focus at (4,6) and the directrix y = -6. Which equation represents this parabola?
Answer:
(x - 4)² = 24y
Step-by-step explanation:
In a parabola with focus at (x, y) and directrix at y = k - p, we can write;
Focus: (h, (k + p))
Directrix: y = k - p
We are given focus at (4, 6)
Thus;
h = 4 &
k + p = 6 - - - (1)
Also, directrix at y = -6
Thus;
k - p = -6 - - - (2)
Adding eq(1) and eq(2) together gives us;
2k = 0
k = 0
Thus, p = 6
The equation takes the formula;
(x - h)² = 4p(y - k)
Plugging in the relevant values;
(x - 4)² = 4(6)(y - 0)
(x - 4)² = 24y
Answer:
(x-4)^2=24y

isolate the variable on the following problem. show your work.
-2=-4+x
Answer:
x=2
Step-by-step explanation:
Add 4 to both sides:
-2=-4+x
-2+4=-4+4+x
2=x
Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
First we must add 4 to both sides.
[tex]-2 = -4 + x[/tex]
+4 +4
-4 + 4 = 0
-2 +4 = 2
Isolating a variable means that it is alone on its side of the eqation.
[tex]2 = x[/tex]
x is now isolated and we also have the solution for it.
[tex]x = 2[/tex]
