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:

55%

Step-by-step explanation:

$598.99–$385.99

=$213

$213/$385.99 × 100%

=55%

The  profit percent is 55.1%.

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%.

2.y =-2x+3. Yes. Came as above. The x intercepts are (3/2,0) and the y is (0,3)

3. x= -2. No because it is a straight line or vertical line up the -2

Answer:

200

Step-by-step explanation:

x-15% of x= Rs.170

x - 0.15x = 170

0.85x = 170

x = 170/0.85

x = 17000/85

x = 200

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 :)

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

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]

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

4250 km

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.
