Here is what I got for the first one.
MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|) =1/5(2+0+4+7+13)) =5.2
And for the second one I got,
MAD= 1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|) =1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|) =1/5(1+2+8+7+4)) =4.4

answer = 4.4

They will have the same coordinate,so we can just find out x and y

3x-y=9(1)
y=-2x+11(2)
Put (2) into(1)
3x-(-2x+11)=9
3x+2x-11=9
5x=20
x=4
Put x=4 into (1)
3(4)-y=9
12-y=9
y=3
Answer is A

Vinil7 [7]

The total cost that will be paid by the family will be RM(15x - y).

<h3>How to calculate the cost?</h3>

The entrance fee to a circus for a child is RM(3x-y).

The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.

Therefore, the cost for 2 adults and three children will be:

= 2(3x + y) + 3(3x - y)

= 6x + 2y + 9x- 3y

= 15x - y

I really need help! :'( Domain= ? Range= ?

hodyreva [135]

Domain = {x|x = 2, 9, 6}
Range = {y|y = c, 0}

I think this is the answer? I tried, it's better to fill it in than to leave it blank :/

the total attendance at a concert in a theater hall was 1500, of this total 400 were children,850 were women , and the remaining

AleksandrR [38]

Answer:

Below!

Step-by step explanation:

We know that:

400 + 850 + m = 1500

Solution of Question A:

Percent of children: Total children/Total attendance

=> 400/1500
=> 4/15
=> 0.27 (Rounded to nearest hundredth)
=> 0.27 x 100
=> 27%

Hence, the percent of children is about 27%.

Solution of Question B:

Percent of women: Total women/Total attendance

=> 850/1500
=> 85/150
=> 17/30
=> 17/30 x 100
=> 17/3 x 10
=> 170/3
=> 56.67%

Hence, the percent of women is 56.67%.

Solution of Question C:

400 + 850 + m = 1500
=> 1250 + m = 1500
=> m = 1500 - 1250
=> m = 250

Percent of men: Total men/Total attendance

=> 250/1500
=> 1/6
=> 0.17 (Rounded to nearest hundredth)
=> 0.17 x 100
=> 17%

Hence, the percent of men is about 17%

Hoped this helped.

Please help with question A and show work!! thank you

Digiron [165]

The equation for the line of reflection is x = 2.
If you drew a vertical line crossing the x-axis on x = 2, the drawing will be the same on the left and right side, as if one side was drawn then exactly copied on the other side but flipped.
The figure is symmetrical, and x = 2 is the line of symmetry.
Hope this helps!
