Answer:

Undefined slope, vertical line

Step-by-step explanation:

Slope = [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

Slope = [tex]\frac{-7 -(-9)}{-9-(-9)} = \frac{-7+9}{-9+9} =\frac{2}{0}[/tex] = Undefined

Since the slope is undefined, you would have a vertical line.

Answer:

first one is 42/7 = 6

11*6 = 66

second one

1/2 inch = 3/2 feet

17/2 inches = 17*3 = 51/2 = 25.5

Answer:

Question 4

You have actual length of the stage is 42 feet and the scale drawing is 11cm: 7ft. Divide the 42 by 7 and the answer is 6. You would need 6 of the 7 ft increments to equal the total of the 42 ft stage. If you multiply one side of a ratio, then you have to multiply both sides. 11 x 6= 66!

Step-by-step explanation:

42/7 = 6

11cm x 6: 7ft x 6

66cm: 42ft

Question 5

You have an actual length of the garage is 8 1/2 inches, or 8.5 inches on the blueprint. It take 2 of the 1/2 inch segments to get 1 inch. You need 8 1/2 or 8.5 total inches. You have to multiply 8.5 by 2 to get the total number of 1/2 inch increments that you need. 8.5 x 2 = 17. This tells you that you would need 17 of the 1/2 increments to get your total blueprint length. If you multiply one side of a ratio, then you have to multiply the other side. 17 x 1 1/2 or 1.5 = 25.5

Step-by-step explanation:

1/2 inch or 0.5 inch x 2 = 1 inch

8 1/2 inches or 8.5 inches x 2 increments = 17 increments

1 1/2 ft or 1.5 ft x 17 = 25.5 ft

Answer:

If the mean time to respond to a stimulus is much higher than the median time to respond, the shape of the distribution of response times is positively skewed

For a distribution, the following are the relationships between the mean and the median values

When the mean is greater than the median, it means that the distribution is skewed right or positively skewed

Hence, the shape of the distribution of response times is positively skewed.

Answer:

unit rate: [tex]\frac{1}{8}[/tex]  .....main answer.

equation: y = [tex]\frac{x}{8}[/tex] .......use it to find any given points.

Explanation:

Take two comfortable best coordinates: ( 1 , 1/8 ) , ( 2 , 2/8 )

slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{\frac{2}{8} -\frac{1}{8} }{2-1}[/tex]

[tex]\frac{1}{8}[/tex] ...this is the slope and the unit rate of the situation(m)

Step-by-step explanation:

We have to calculate the annual interest rate for the account. Formula for the simple interest is : I = P * r * t, where P is the investment, r is the annual interest rate and t is time in years. In this case: 1,800 = 10,000 * r * 4; 1,800 = 40,000 * r; r = 1,800 : 40,000; r = 0.045, or 4.5 %. Answer: The annual interest rate is 4.5 %

Hi!

We can use point-slope form to solve this.

[tex]y-y_{1} =m(x -x_{1})[/tex]

[tex]y_{1}[/tex] and [tex]x_{1}[/tex] will be from one of the points.

First, we have to find [tex]m[/tex], the slope. We can use the slope equation to get this.

[tex]\frac{y_{1} -y_{2} }{x_{1} -x_{2} }[/tex]

Plug in your points:

[tex]\frac{4-0}{8-(-8)} =\frac{4-0}{8+8} =\frac{4}{16} =\frac{1}{4}[/tex]

Your slope is [tex]\frac{1}{4}[/tex]

Now plug points and slope into point-slope equation. We will use (8, 4).

[tex]y-4=\frac{1}{4} (x-8)[/tex]

Now, if you want to get it into y = mx + b form, you have to solve for y:

[tex]y-4=\frac{1}{4} (x-8)[/tex]

[tex]y-4=\frac{1}{4} x-2[/tex]

[tex]y=\frac{1}{4} +2[/tex]

Your equation is [tex]y=\frac{1}{4} +2[/tex]
