What is the MAD of the data set?

{13, 6, 3, 7, 11}

Answers

Answer 1

Answer: 13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5
6 - 8 = |-2| = 2
3 - 8 = |-5| = 5
7 - 8 = |-1| = 1
11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2

Answer 2

Answer:

Answer:

MAD = 3.2

Step-by-step explanation:

13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5

6 - 8 = |-2| = 2

3 - 8 = |-5| = 5

7 - 8 = |-1| = 1

11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2

Answers

Answer:

1)For, m = 3/4 , (0,4) , 4y - 16 - 3x = 0 is the equation of line.

2)For, m = 4 , (-2,-5) , y - 4x - 4 = 0 is the equation of line.

3)For, m = -1/3 , (4,-1) , x + 3y -1 = 0 is the equation of line.

Step-by-step explanation:

If m is the slope and (x0,y0) is the point on any given equation, then

by POINT SLOPE FORMULA:

The line equation is given as (y - y0) = m (x -x0)

Now , here:

1) m = 3/4 , (x0, y0) = (0.4)

So,, the equation of line is $(y-4) = (3)/(4) (x-0)\nor, 4(y-4) = 3x$

on simplification, 4y - 16 - 3x = 0 is the equation of line.

2) m = 4 , (x0, y0) = (-2.-5)

So,, the equation of line is $(y-(-5)) = 4 * (x-(-2))\nor, (y+4) = 4(x+2)$

on simplification, y - 4x - 4 = 0 is the equation of line.

3) m = -1/3 , (x0, y0) = (4, -1)

So,, the equation of line is $(y-(-1)) = (-1)/(3) (x-4)\nor, 3(y+1) = -(x-4)$

on simplification, x + 3y -1 = 0 is the equation of line.

Which equation represents a proportional relationship that has a constant of proportionality equal to –10? y = x minus 10 y = StartFraction over negative 10 EndFraction y = negative 10 x y = negative 10

Answers

Answer:

The correct answer would be C. y = -10x

Step-by-step explanation: We cam eliminate the first two by common sense, that would leave us with options C, and D. The correct answer would be C, the reason it is not D is because D isn't a proportion, y = -10 is just stating that variable y equals -10, whereas, y = -10x represents a proportion.

Lisa's recipe for 6 dozen cookies has 3/4 cup of butter and 1 1/2 cups of sugar. How much butter does she need to make only 3 dozen cookies?

Answers

Dozen = 12
6 Dozen = 12 * 6 = 72 <- Irrelevant but useful information

3 dozen is half of 6 dozen, so we just half the recipe!
3/4 cup of butter = 3/8 cups (doubling the denominator is the same as halving)
1 1/2 cups of sugar (3/2 cups) = 3/4 cups

She needs 3/8 cups of butter, and a 3/4 cup of sugar

Please give me brainliest answer if I helped! I need it for my next rank :D

This is basic alegbra, you set up a proportions equations with dozen of cookies over butter. 6/ 3/4 equals 3/x. You cross multiply, 6x equals 2 1/4. You divide 6 on both sides of the equation to isolate x, the variable. 2 1/4 divided by 6 equals 0.375. The answer is 0.375 cups of butter
