Answer:

you get (2x+3), because 14 divided by 7 = 2 and 21 divided by 7 = 3

Based on given information for each of the following, which lines cannot be parallel? a m∠2=127°, m∠3=63°\ PLZZSZZZ help :&gt;
tia_tia [17]

Answer:

Lines m and n cannot be parallel

Step-by-step explanation:

1. Because angles 2 and 3 are Same Side Interior Angles, they must be supplementary.

2. To check this you add the angles together (127 + 63) and it sums to 190 degrees, not 180

3. Since they don't agree with the laws of parallel lines, the lines that the angles are on can't be parallel

4. Angles 2 and 3 reside on lines m and n so lines m and n cannot be parallel

maw [93]
Well, 9 is the largest, but 4 is the smallest and 3 is the second odd number. So it would go yes, no, no or if it's just one question, it would be no.

Answer:

The correct option is;

The situation shows correlation without causation

Step-by-step explanation:

The given data are;

Weight y     {}            Miles Per Gallon

42     {}                           18

36     {}                           12

30     {}                            6

.     {}                                x

24     {}                            0

The first difference of the data = 42 - 36 = 36  - 30 = 30 - 24 = 6

18 - 12 = 12 - 6 = 6 - 0 = 6

The first difference of the data is constant and equal to 6

Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;

The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;

(42 - 24)/(18 - 0) = 1

Therefore, the points of the data fit into the straight line and the data of the situation shows correlation

In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.
