9. Write an equation for the line that is parallel to the given line and that passes through the given point.
timurjin [86]

Answer:

  y -11 = 2(x -3)

Step-by-step explanation:

The slope of the given line is the x-coefficient: 2. The parallel line will have the same slope.

When you know the slope and a point on the line, it is convenient to use the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Your line's equation is ...

  y -11 = 2(x -3)

An NBC News/Wall Street Journal poll conducted in 2010 predicted that 61% of Americans did not support the Tea Party movement. I
fomenos

Answer:

The right answer is:

The poll provides strong evidence that more than 61% of Americans oppose the Tea Party movement this year. Why? The P-value (0.026) is less than the significance level of 5%.

Step-by-step explanation:

At a level of significance of 5%, a P-value of 0.026 (2.6%) means that the difference is significant and the null hypothesis is rejected.

The difference between the proportions is significant, what means that more than 61% of Americans oppose the Tea Party movement this year.

Note: The difference in the sample proportions (3%) is not enough to claim that the difference is significant.

The right answer is:

The poll provides strong evidence that more than 61% of Americans oppose the Tea Party movement this year. Why? The P-value (0.026) is less than the significance level of 5%.

Whats the the answer to this math problem
GrogVix [38]

Answer:

9 inches

Step-by-step explanation:

*Keep in mind, the length value is only greater than the width by 2.

15 ÷ 5 = 3

(So the length is increasing by 3, which means what? The width will also increase by 3. Now just multiply)

3 • 3 = 9
