Answer:

6

Step-by-step explanation:

The interquartile range is the 3rd quartile - the 1st quartile.

Quartiles  Quartiles:

Q1 -->               6

Q2 -->              9

Q3 -->              12

Thus 12-6 = 6

Answer: 0 ≤ x ≤ 4

Step-by-step explanation:

The cost equation can be written as:

y = $2 + $0.75*x

Where x is the number of ounces that you buy.

If you can spend between $2 and $5, then we have the inequality:

$2 ≤ y ≤ $5

replacing y by the above equation:

$2 ≤  $2 + $0.75*x ≤ $5

Now let's solve this for x.

$2 - $2 ≤ ($2 + $0.75*x) - $2 ≤ $5 - $2

$0 ≤ $0.75*x ≤ $3

now we can divide bt $0.75 in the 3 sides:

$0/$0.75 ≤ ($0.75*x)/$0.75 ≤ $3/$0.75

0 ≤ x ≤ 4

Then the domain is:

D: 0 ≤ x ≤ 4

or we can also write this as:

D = x ∈ [0, 4]

Answer:

<XYZ = <CBD

Step-by-step explanation:

this is the right answer I can confirm

Answer:

The solution lies at approximately (4.25,6.5).

Step-by-step explanation:

The estimate is pretty close for both equations. For the first equation, the estimate results in a value that is only 0.2125 units away from the constant. For the second equation, the estimate results in a value that is only 0.25 units away from the constant.

Answer:

- 1/2 or - 1.5

Step-by-step explanation:

I would suggest using a table

x       y

2      -1

0      0

from -1 to 0, you add 1

from 2 to 0, u subtract 2

so y/x

1/-2

Your slope will be -1/2 or -1.5

Hope this helped!

Answer:

[tex]m=0[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

Point (-12, 1)

Point (4, 1)

Step 2: Find slope m

Answer:

zero; it is a horizontal line

Step-by-step explanation:

equation of slope: [tex]\frac{y1-y2}{x1-x2}[/tex]         (-12, 1) (4, 1)

[tex]\frac{1-1}{-12-4}[/tex] = [tex]\frac{0}{-16}[/tex]

Because the numerator is zero, the slope of the line is zero. It is a horizontal line.

Answer:

y-b+am/m

Step-by-step explanation:

y-b=m(x-a)

y-b=MX-ma

mx=y-b+ma

x=y-b+ma/m

Answer:

The sidewalk is 2 feet wide

Step-by-step explanation:

The area of the sidewalk is given as 80 square feet

The length and width of pool

including side walks will be;

10 + 2x and 6 + 2x

To get the area of the side walk

That will be area of total minus area of the pool

That will be ;

(10 + 2x)(6 + 2x) - 10(6) = 80

60 + 12x + 20x + 4x^2 - 60 = 80

4x^2 + 32x -80 = 0

x^2 + 8x -20

x^2 + 10x - 2x - 20 = 0

x(x + 10) -2(x + 10) = 0

(x-2)(x + 10) = 0

x = 2 or -10

since width cannot be negative;

The sidewalk is 2 feet wide

The system of inequalities shown in the graph is x ≤ 4 and y > 1 ⇒ C

Step-by-step explanation:

In the given figure, there are 2 lines, let us find the equations of them, then write the inequalities which represent the shaded areas

∵ The purple line is a vertical line

∵ It is cross the x-axis at the point (4, 0)

→ By using the first rule above

∴ The equation of the purple line is x = 4

∵ The purple line is solid and the shaded area left the line

∴ The sign inequality is ≤

∴ The inequality of the purple area is x ≤ 4

∵ The blue line is a horizontal line

∵ It is cross the y-axis at the point (0, 1)

→ By using the second rule above

∴ The equation of the blue line is y = 1

∵ The blue line is dashed and the shaded area above the line

∴ The sign inequality is >

∴ The inequality of the blue area is y > 1

∴ The system of inequalities shown in the graph is x ≤ 4 and y > 1

Answer:

Before Tax: $37.50 and $32.50

After-Tax: $40.50 and $35.10

Step-by-step explanation:

In order to calculate the sales price we need to turn these percentages into the proper decimals, since they are discounts we would do this by dividing each percentage by 100 and then subtracting them from 1. Then we use those decimals and multiply them by the original cost of the shoes.

25% / 100 = 0.25

1 - 0.25 = 0.75

50.00 * 0.75 = $37.50

30% / 100 = 0.35

1 - 0.35 = 0.65

50.00 * 0.65 = $32.50

Now we see that the sales price for these shoes would range between $37.50 and $32.50. Now we need to add an 8% sales tax, we do this by dividing this percentage by 100 and adding 1 to it. Then we multiply this new value by the new sales prices.

8% / 100 = 0.08

0.08 + 1 = 1.08

$37.50 * 1.08 = $40.50

$32.50 * 1.08 = $35.10

Answer:

The answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.

Step-by-step explanation:

In order to find the answer, first you have to calculate 30% of the amount Mr. Vaughn set aside of his income each month to determine the money he spent to replace the broken water heater:

$200*30%=$60

Now, you have to subtract the amount that represents the 30% from the amount he set aside:

$200-$60=$140

According to this, the answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.

Answer:

(4, -2)

Step-by-step explanation:

if you do process of elimination you find that 'a' doesn't work out but 'b' will . . . substitute -2 for 'y' and 4 for 'x' and see if the equation is true

-2 = -3/4(4) + 1

-2 = -3 + 1

-2 = -2
