The old machines ratio would be 45:30 and the new ratio would be 120:60, but since 120 is how many cookies the machine can cut in an hour, the machine can cut 60 cookies in half an hour (30 min) therefore, the comparison would be 43:60 (Old Machine cookie cutting rate to new machine cookie cutting rate. I hope I helped

A scatter plot is shown below: A graph shows numbers from 0 to 10 on the x axis at increments of 1 and the numbers 0 to 15 on th
Mrrafil [7]

Answer:

B (0, 14) and (10, 1)

Step-by-step explanation:

Option A: (0, 14) and (10, 14)

Equation of line using two point slope form .

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

(x_1,y_1)=(0,14)

(x_2,y_2)=(10,14)

Substitute values in formula :

y-14=\frac{14-14}{`10-0}(x-0)

y-14=0(x-0)

y=14

Option B :  (0, 14) and (10, 1)

Equation of line using two point slope form .

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

(x_1,y_1)=(0,14)

(x_2,y_2)=(10,1)

Substitute values in formula :

y-14=\frac{1-14}{`10-0}(x-0)

y-14=\frac{-13}{10}(x-0)

y=\frac{-13}{10}x+14

Option C: (0, 7) and (7, 0)

Equation of line using two point slope form .

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

(x_1,y_1)=(0,7)

(x_2,y_2)=(7,0)

Substitute values in formula :

y-7=\frac{0-7}{`7-0}(x-0)

y-7=\frac{-7}{7}(x)

y= -x+7

Option D: (0, 7) and (3, 0)

Equation of line using two point slope form .

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

(x_1,y_1)=(0,7)

(x_2,y_2)=(3,0)

Substitute values in formula :

y-7=\frac{0-7}{`3-0}(x-0)

y-7=\frac{-7}{3}(x)

y=\frac{-7}{3}(x)+7

Now after plotting all the lines of given options on the graph of scatter plot we can see that the blue line y=\frac{-13}{10}x+14 of Option B  the is the line of best fit for this scatter plot Since it is covering almost all ordered pairs of scatter plot.

Hence two ordered pairs can be joined to best draw the line of best fit for this scatter plot are  (0, 14) and (10, 1)

Option B is correct.

Step-by-step explanation:

Pythagorean theorem is used

We will call AB x

x^2 + 6^2 = 8^2

x^2 + 36 = 64

x^2 = 28

x = 5.2915026
