Answer:

The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195

Step-by-step explanation:

P.S - The exact question is -

Given - The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below.

                                       Sidney’s Grades           Phil’s Grades

Mean                                     82                                    78

Mean Absolute Deviation      3.28                                 3.96

To find - Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?

Proof -

Given that Mean of Sidney Grades = 82

                 Mean of Phil's   Grades = 78

So,

The difference of two means = 82 - 78 = 4

Also,

Given, Mean Absolute Deviation of Sydney = 3.28

Now,

The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195

Answer:

x = 4.3

Step-by-step explanation:

Given the question :

Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=

Taking out the equation :

1.2x = 5.16

Divudse both sides by 1.2

1.2x/1.2 = 5.16 / 1.2

x = 4.3

Hence, x = 4.3

The value of x in the equation is equal to 4.3

Data;

To solve this problem, we need to first make x the subject of formula and this is done by dividing both sides of coefficient of x.

[tex]\frac{1.2x}{1.2} = \frac{5.16}{1.2}[/tex]

This can be further simplified as

[tex]x = \frac{5.16}{1.2} = 4.3[/tex]

The value of x in the equation is equal to 4.3

Answer:

x = -3

Step-by-step explanation:

24 = 12 - 4x

24 - 12 = -4x

12 = -4x

12/-4 = x

x = -3

Answer:

x=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24=12−4x

24=12+−4x

24=−4x+12

Step 2: Flip the equation.

−4x+12=24

Step 3: Subtract 12 from both sides.

−4x+12−12=24−12

−4x=12

Step 4: Divide both sides by -4.

Answer:

(-2, -6)

Step-by-step explanation:

Given the simultaneous equation

3x-y=0 ... 1

2x+y=-10 ... 2

Add both equations to eliminate y

3x + 2x = 0 - 10

5x = -10

x = -10/5

x = -2

Substitute x = -2 into 1

3(-2)- y = 0

-6 - y = 0

-y = 0+ 6

-y = 6

y = -6

Hence the coordinate (x, y) is (-2, -6)

Answer:

Bushes are $9.

Bonsai trees are $32.

Step-by-step explanation:

Bushes are b and bonsai trees are t.

15b + 8t = $391

9b + 5t = $241

15b + 8t = $391 × 3 and 9b + 5t = $241 × 5

= 45b + 24t = $1173 and 45b + 25t = $1205

(45b + 24t = $1173) - (45b + 25t = $1205)

t = 1205 - 1173

t = $32

Apply to 15b + 8t = $391.

15b + 32 × 8 = $391

15b = $391 = 32 × 8

15b = $391 - 256

15b = $135

x = ($135 ÷ 15) = $9

Answer:

8 2/3

Step-by-step explanation:

First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2  divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.

Answer:

Step-by-step explanation:

- The # in front of x will be the number that hits on the y-axis

- The # after x or the slope, ex: y = -1/2x + 2, is how much you move to hit the next point on the graph

-  2 would actually be 2/1 so move up 2 and right 1 (if the number or fraction is negative then go up and to the left

- So y = -2x - 1/2, negative slope. Start at -2 on y-axis and go up 1 then left 2.
